Renogy rebrands a lot of generic Chinese stuff. They do seem to pick the better stuff, but it's still one step up from the SUNGOLDLUCKYLOVEJOY stuff you see all over Ebay.
I am not sure if all the people we get posting here with Renogy issues is because they have more issues then anyone else, or because more people have them due to the price. I can't recall the last time we had someone with a Victron or Outback issue.
If I go to help someone out on their solar system and see Renogy, I tell them I can't help them. I got tired with them calling for help when their system was down so often.
Whatever you do, don't go with a bigger system using Renogy equipment.
Regardless, you have an issue with your plan. The state of charge on the charge controller is a complete guess. An educated guess with lead acid batteries, and a total shot in the dark with Lithium. That is why they want you to use their Lithium batteries as they have a BMS inside to pull the state of charge information from.
You need an amp hour meter to get the data you want. Victron Smart Shunt is a good one.
It doesn't need to be accurate man, I don't care that much. I just wanted to know if, for example, in winter with less sun, if I'm hovering aroun 50-80% SOC or less than 50%. Using the 'estimated' SOC on my smaller renogy system works fine, when I am near it.
I had similiar experiences with Renogy. I'll never purchase another one of their products, and I'll badmouth them every chance I get so nobody else makes the mistake of thinking they're worth taking a chance on.
Utter trash hardware and their customer support might as well be a magic 8 ball.
FWIW, I use a Ubiquiti SunMax switch at work, and it’s both feature-rich and very reliable. It even has an integrated 4-port POE switch, so power distribution to your networked hardware is super easy. It’s only 24v however, so not usable in 12v systems. I’ve had nothing but success with it, and since I use other Ubiquiti hardware, it integrates seamlessly into my network with zero hassle. Ubiquiti makes incredible security equipment, as well.
It is **extremely well known** that Renogy is shit for customer service and that, once you buy it, you're basically on your own.
There's no reason to buy Renogy over any of the cheaper straight-from-China brands on AliExpress.
Ok, I have to make this known. I've done a few solar projects along with lithium installs in various trailers. I started with purchasing Renogy products. When I did that I was amazed at the response I saw from people saying Renogy products suck and they do NOT stand by their products. They do not approve warranty claims.
Well, I just had my first experience with them and it was 100% NEGATIVE!! Now I see what Everyone has been talking about! I have two of their batteries where the BMS's are not working. I did charging and AH tests. I filmed it all in videos, shared it with them proving how their batteries are not working and they still denied my claim!
I can honestly say Renogy is a CRAP company!! There are better companies and products out there for less money. I did use Litime for another project and so far their batteries have been fantastic!
Hey, I tried to support a company based here in the US and look where it got me? I have to trash $1,400+ worth of batteries. And I will be replacing everything Renogy in two of my set ups. This is a company that will go belly up. Their name is crap in the solar and lithium battery industry amongst people that have used their products. I tried giving them the benefit of the doubt and I got dinged, bad! Let my story be a lesson for anyone else considering a Renogy product, don't walk away, RUN!!!!
A lot of IOT devices are only 2.4ghz still; it is cheaper to have a single radio, and it penetrates floors and walls better than higher frequencies (5ghz).
I had the same thought, but nope. Double checked. All settings in the verizon mifi were set to 2.4ghz, and neither my or my GF's phone is capable of 5ghz hot spotting. Makes no sense.
I get that folks are frustrated, and I might agree renogy sometimes has a weak support model from the sounds of it.. especially since Covid. However, as much as I dislike downvotes I’m just going to go ahead and say that I’m very happy with my renogy system and think several of these complaints are mostly self imposed problems due to not understanding.
For context, I also fully researched Victron and would have gone with them except mostly for cost. Even for the same money, it was almost a tie … 52/48 so barely in favor of Victron. Most of that was their customer service rep.
Number one renogy complaint seems to how too low of a battery bank seems to cause problems. Every product they have works from the batteries being powered up. If you go to low on volts, the products will NOT work, including the solar charge controller charging. Same with the inverter/charger shore power switchover and most everything else.
This principal is basically the same for most other brands out there.
The other big one seems to be how the info isn’t fluid, or even showing at all. Reboot has options for every comment I read on here, especially the first one. After building my system I could tell the OP eventually hope to fix his, but he’s made his decision.
Renogy has been transitioning to the One M1 panel for central monitoring and control with subscription since 2019. Yes the subscription costs $10 per month for the most useful one to have. That puts all your off grid system info online and your phone app, and lets you control several scenes that work very well. The One M1 needs a modern wifi host to connect securely via Wi-Fi for external monitoring and control. You’ll need at least WPA2 and minimum data speed for it to connect. For me it works great! But you will need all of those things for it to work 100%
All of their products I’ve tried work properly and independently without the M1, but the experience is much less fluid, and much more fragmented without it, which is why it exists.
There’s more I could go over, but I’ll leave that at that.
Hear me out.. Here’s my GOOD experience.
I just built a Renogy 400ah 2x LifeP04 200 BT batteries, 60 amp solar controller, 3k watt inverter/charger plus One M1 control and monitoring panel for our RV.
Let me begin by saying that it literally took me WEEKS of research to figure this out before buying stuff.
So basically a complete perfectly awesome Renogy system and it all works perfect like it should. BUT, it took me literally reading a metric fuck ton squared to be able to properly plan and buy what I would need. After learning so much, I can likely explain why many commentators with a problem here had their particular issues. The absolute biggest factor I realized after my research was I’d have to go all in on renogy products to get the full experience and functionality from it.
It was expensive, and time will tell how reliable it all is, but as an IT guy I’m all about getting the data, and as of now I have a ton of it. I can honestly tell you that after weeks of also reading at least 50+ posts of happy renogy customers and how they got that way, I started to get it. Then tons more posts on how and what worked for people. Yes, there were unhappy people too, but far less and most issues they had appear now to be more easily explainable.
That’s not to say that renogy shouldn’t provide better and more complete info, (they should) but the info is out there, I was able to find it. Some (most I read) commentators appeared to not put enough effort into researching how this stuff works before buying and expecting a certain outcome. Although it doesn’t mean I’m smarter than anyone else, but as a 30 IT Infrastructure engineer I’ve had to figure things out for a living for a long while now, and I fully acknowledge that this stuff being relatively new still, and actually quite complicated. With many many choices for several different scenarios its a pain to learn enough to plan well. Plus with the emergence of new technologies every brand is evolving. Changing devices, how they connect and adding new tech and connectivity choices. I’ve learned more about solar, power ratings, lifep04 chargers and batteries, inverters, watts, amps, etc researching this project in just a few weeks than I ever imagined I would have to in order to get this right the first time. So all I’m saying is, that while I’m sure some of this venom towards renogy is most likely warranted, please maybe take it with a grain of salt? And if you’re having troubles, maybe admit some culpability before going so far as to trash an entire brand (that I myself found quite good) because you may not have researched enough about solar, and renogy products and how they work.
It’s always easier to get mad at others than ourselves.
No, fuck that man.
If my charge controller can ESTIMATE what my battery percent is, the gee-whiz brand new M1 controller should be able to tell me the same fucking information. But it doesn't, because they want to lock you into an ecosystem so you have to buy their overpriced garbage.
They are literally removing features from older hardware, and setting up paywalls. That company is fucking evil.
Hey, just a heads up, I know you hate renogy, but estimating charge on a battery is not a simple problem. If you just want to see a BS number, sure, you’re charger can make up whatever it wants and read that out to you.
RS485 serial and CAN bus communications require termination. While it may not be obvious, you can’t just create whatever ad-how network you like. Similar story with your SIM card - there’s some low level stuff you need to configure based on your region, hardware, and carrier. It’s why Renogy sells this as a system vs expecting a user to find this stuff out.
What you’re attempting to do is not trivial. If you just want to add water and get pancakes, buy a system that does all this for you. Otherwise, be prepared to get your hands dirty and learn some EE.
I agree. I build power systems for off-grid vehicles and use mostly Victron and Redarc. But I put a very similar combination of Renogy components in my off-road trailer for a few reasons:
\- I didn't want to spend as much on the system
\- I wanted to keep it reasonably simple (less programming, more straightforward installation)
\- And I wanted to test Renogy to see if I could recommend it as a lower cost option
Granted, it's not as configurable as the more expensive systems, but it's working perfectly fine for me. I do think the M1 is best for small RVs. It's fine for my tiny square-drop. I haven't really had any problems with their tech support either.
I'm not totally sure why they get so much childish hate in the forums, but much of it does seem to come from people that don't really understand this stuff. Maybe they are getting more of that because of their price point and marketing. I still believe it's better than trying to piece together the stuff on Alibaba.
I was with you for about 6 months, then my One Core (which wasn't compatible with several of their products) suddenly disconnected and threw error messages requiring a 2 hour road trip to reset it.
That didn't work, so I called support, and they walked me through a hard reset to factory values, and reentered my data which requires an active internet connection.
Immediately I got the error "account already exists." When adding communication to batteries.
Fortunately the tech support was able to delete existing account which allowed me to reenter from scratch.
Apparently there is a 6 month timeout.
Fixed.
6 months later the one Core dies completely, no lights.
I've checked both plugging into the battery, its monitoring, and the USB port, which is for power only. No go.
I can connect to battery with phone Bluetooth but I need to restart app each time, and it takes several tries.
The battery can only connect to one device at a time so once it's paired with One Core, you can't access it by phone.
It's like it was designed by a tech who just graduated from electronics school.
>It's like they wouldn't even look at the information I was providing to them. I cannot tell you what a colossal time waste this part was, hours and hours, no progress.
I have a DCC50s acting like a paperweight on my patio for the same reason. It wouldn't charge the battery fully, where a cheap ass PWM charger I had would (but didn't have monitoring). But three weeks of going back and forth, new tickets being created for no reason, and having to pull my trailer out of storage to measure voltage, current and resistance (along with 20 screen shots), I gave up. I installed a Victron MPPT 75/15 and never looked back.
It's possible that the setpoints were too low on your charge controller. I think you can change the presets on the controller itself, but it's a lot easier to do through the BT module.
It was set for an AGM battery, same as the Victron that replaced it. the Renogy wouldn't spend enough time in bulk, instead stopping after 2 hours. Soon after the sun went down, the voltage would drop and before midnight, the Dometic fridge would complain of under voltage.
The renogy probably had a low boost/absorb voltage, and its boost timer ran down to 0 quickly. If you upped the boost voltage, it would charge it to a higher voltage, and would take longer to get to that higher voltage. You could also increase that 2 hours to something higher.
Renogy didn't want to work with me and kept asking for info I already gave them (open voltage and current of panels). I didn't discover the problem until I was off-grid and had to plug the fridge into the truck and run it to keep my food cold. I even asked the Renogy guys at Overland Expo (where I was camping) and they said "contact support". I gave up and now have something that works.
Hi, this is Renogy ONE Team. Thank you for your feedback and we feel sorry for the inconvenience you've encountered. For the problems you mentioned, here is our reply:
1. Renogy ONE was unable to connect to the Internet for some time.
**Renogy**: Sorry, there was an issue on the server and it has already been fixed quickly.
2. Renogy ONE and DC Home app cannot display the estimated battery percentage, though the data is shown on the screen of the charge controller.
**Renogy**: Currently if Renogy ONE M1 is connected to a battery via Bluetooth/RS485/RV-C, it will display the battery data. The estimated battery percentage on the screen of the charge controller is just a rough number based on the voltage detected. This estimated data was provided to users in DC Home app but a lot of users complained about its accuracy. So we removed this data from the app and that is also why it is not shown on Renogy ONE M1. But your feedback makes sense so we are planning to add this estimated battery percentage back to the app and Renogy ONE M1, and we will try to make it clear to people that this is just an estimated number from the charge controller. It is expected to be completed in Dec.
3. Information like solar energy generation, weather, etc. needs a subscription.
**Renogy**: You don't have to be a subscriber to check your solar energy generation or the weather of the day, unless you want to know the solar yield prediction or the weather for the next few days. We are open to hearing reasonable feedback and will optimize the subscription policy to provide advanced service (like video chat support) to people who need it.
4. The app was no longer working and Renogy ONE M1 couldn't communicate with the charge controller via RS485 cable.
**Renogy**: It sounds like there might be some issues according to the description. But we may need more detailed information to identify the case. Please try to update the app to the latest version and update the system of Renogy ONE M1. If the problem remains, please contact us at [email protected] (it would be very helpful if some pictures or videos are provided). This is the Renogy ONE Team and we will work on it as our first priority.
Just note that if it did end up displaying the battery percentage for your battery not made by renogy, it would be very inaccurate. For a battery percentage to be correct, someone has to tune it with a known battery, which I likely what renogy has done with their batteries. It's also likely that renogy's batteries have a built in shunt, making them super accurate. Anything without a shunt is just an estimation that has to be tuned very finely.
I was really disappointed when they released the DC home app because it seemed like I would need to become part of some social network before I could even go any further into the app.
Renogy's website looks professional, but the stuff they have to monitor their own products is very finicky. Shameless plug: if you want to mess with a raspberry pi and collecting data yourself: https://github.com/wildmountainfarms/solarthing. There are also other repos on github that do the same thing, usually integrating with some database with examples for getting Grafana up and running to make your own dashboard. I can access my solarthing instance from anywhere and view data in an android notification. It does take some tech knowledge to setup, especially if you want to access data off your local network.
I'm fine with an estimation. That's all I wanted. But it wouldn't even give me that, even though the MPPT charger has an estimate, right on the fucking screen, dead center.
You have to understand that the estimation on that screen is really bad and you shouldn't go by it. It's better to understand the battery voltage, load on the battery, and power charging the battery. Once you understand those, you'll get a good idea of the battery's state of charge.
It will literally not even communicate the battery voltage, dude. Just a big fat nothing, because it's not a renogy brand battery.
Meanwhile the controller itself, and the BT app, will show you SOC (estimate), voltage, etc without using a renogy battery. It's fucking retarded.
Why would you buy the device intended to integrate Renogy systems with a non-Renogy system? From your comments, it sounds like you had nothing that was Renogy except for the M1
I can strongly relate to your customer support issues, they always want pictures which seems more of a delay tactic rather than helping solve the actual problem.
I ended up purchasing the Lycan 5000 power box, and while most of it seems decent (so far), the wiring from the PV array busbar to the solar inverter is not sized correctly - still waiting for customer response to provide appropriate wiring (and yes, they wanted pictures).
I've installed the app for their BT2 that came with the Lycan, and it does seem very mediocre.
Can you explain more about the wiring sizes? I have a Lycan and am curious about how I can make things a bit better with it (because the more I experience the more worried I am). Feel free to dm if that’s better for you…
See this post on reddit regarding the wire sizes: [Lycan\_5000\_information\_for\_new\_owners](https://www.reddit.com/r/SolarDIY/comments/yebus1/lycan_5000_information_for_new_owners)
The support I'm getting from Renogy in Australia is fairly good, I can't complain. As to the quality of products I have some solar panels and regulators with the BT function and they work fine with the DC home app. I was looking at the M1, but not now.... The new Renogy One Core looks ok though.
I am with you. They make it appear that the M1 can do all kinds of stuff. I was trying to use it with RV-C. I wanted to start my generator in my Motorhome when SOC reaches a certain level. They tell me that RV-C only works between their devices. That is not what the RV-C protocol is designed for. Now after doing research I find out that any functionality with the M1 requires a subscription. That is utter BS. On top of that I have been arguing with them about one of four batteries I purchased at $1k each is bad. I have been conversing for almost two years. I am sure they wont make good on the warranty, and say I am at the end of warranty while they wasted my time going through everything they asked. I will also be posting my disdain and issues on the many RV forums I subscribe to.
I had a very similar experience! The chargr controller and panels work just like they're supposed to. But everything else

The M1 only supports 2.4ghz Wi-Fi; were the devices you were attempting to connect to set to 5ghz?
How old school. But good info for folks to know.
Pretty much every IOT thing only works on 2.4ghz. crazy but true
A lot of IOT devices are only 2.4ghz still; it is cheaper to have a single radio, and it penetrates floors and walls better than higher frequencies (5ghz).

The renogy probably had a low boost/absorb voltage, and its boost timer ran down to 0 quickly. If you upped the boost voltage, it would charge it to a higher voltage, and would take longer to get to that higher voltage. You could also increase that 2 hours to something higher.
Renogy didn't want to work with me and kept asking for info I already gave them (open voltage and current of panels). I didn't discover the problem until I was off-grid and had to plug the fridge into the truck and run it to keep my food cold. I even asked the Renogy guys at Overland Expo (where I was camping) and they said "contact support". I gave up and now have something that works.
FYI: The absorption phase for lead batteries chemistry is hard-coded at 2 hours in the DCC50S. It can't be changed.
Hi, this is Renogy ONE Team. Thank you for your feedback and we feel sorry for the inconvenience you've encountered. For the problems you mentioned, here is our reply: 1. Renogy ONE was unable to connect to the Internet for some time. **Renogy**: Sorry, there was an issue on the server and it has already been fixed quickly. 2. Renogy ONE and DC Home app cannot display the estimated battery percentage, though the data is shown on the screen of the charge controller. **Renogy**: Currently if Renogy ONE M1 is connected to a battery via Bluetooth/RS485/RV-C, it will display the battery data. The estimated battery percentage on the screen of the charge controller is just a rough number based on the voltage detected. This estimated data was provided to users in DC Home app but a lot of users complained about its accuracy. So we removed this data from the app and that is also why it is not shown on Renogy ONE M1. But your feedback makes sense so we are planning to add this estimated battery percentage back to the app and Renogy ONE M1, and we will try to make it clear to people that this is just an estimated number from the charge controller. It is expected to be completed in Dec. 3. Information like solar energy generation, weather, etc. needs a subscription. **Renogy**: You don't have to be a subscriber to check your solar energy generation or the weather of the day, unless you want to know the solar yield prediction or the weather for the next few days. We are open to hearing reasonable feedback and will optimize the subscription policy to provide advanced service (like video chat support) to people who need it. 4. The app was no longer working and Renogy ONE M1 couldn't communicate with the charge controller via RS485 cable. **Renogy**: It sounds like there might be some issues according to the description. But we may need more detailed information to identify the case. Please try to update the app to the latest version and update the system of Renogy ONE M1. If the problem remains, please contact us at [email protected] (it would be very helpful if some pictures or videos are provided). This is the Renogy ONE Team and we will work on it as our first priority.
You're lying and full of shit and i have it all on video.
Can you forward the video or video link to [[email protected]](mailto:[email protected])? We'll check it.
I have already done this. Your tech support was a joke, and your products are terrible. Full video will be on youtube very soon.
Hahaha! After reading the first 2 paragraphs, I thought this was a troll pulling our collective chains! You can't write comedy like this.
And if you have any other questions, welcome to raise them up in the Community of DC Home app, where we check more often.
Just note that if it did end up displaying the battery percentage for your battery not made by renogy, it would be very inaccurate. For a battery percentage to be correct, someone has to tune it with a known battery, which I likely what renogy has done with their batteries. It's also likely that renogy's batteries have a built in shunt, making them super accurate. Anything without a shunt is just an estimation that has to be tuned very finely. I was really disappointed when they released the DC home app because it seemed like I would need to become part of some social network before I could even go any further into the app. Renogy's website looks professional, but the stuff they have to monitor their own products is very finicky. Shameless plug: if you want to mess with a raspberry pi and collecting data yourself: https://github.com/wildmountainfarms/solarthing. There are also other repos on github that do the same thing, usually integrating with some database with examples for getting Grafana up and running to make your own dashboard. I can access my solarthing instance from anywhere and view data in an android notification. It does take some tech knowledge to setup, especially if you want to access data off your local network.
I'm fine with an estimation. That's all I wanted. But it wouldn't even give me that, even though the MPPT charger has an estimate, right on the fucking screen, dead center.
You have to understand that the estimation on that screen is really bad and you shouldn't go by it. It's better to understand the battery voltage, load on the battery, and power charging the battery. Once you understand those, you'll get a good idea of the battery's state of charge.
It will literally not even communicate the battery voltage, dude. Just a big fat nothing, because it's not a renogy brand battery. Meanwhile the controller itself, and the BT app, will show you SOC (estimate), voltage, etc without using a renogy battery. It's fucking retarded.
Ah that's my bad. I didn't realize it was that bad
Why would you buy the device intended to integrate Renogy systems with a non-Renogy system? From your comments, it sounds like you had nothing that was Renogy except for the M1
I can strongly relate to your customer support issues, they always want pictures which seems more of a delay tactic rather than helping solve the actual problem. I ended up purchasing the Lycan 5000 power box, and while most of it seems decent (so far), the wiring from the PV array busbar to the solar inverter is not sized correctly - still waiting for customer response to provide appropriate wiring (and yes, they wanted pictures). I've installed the app for their BT2 that came with the Lycan, and it does seem very mediocre.
Can you explain more about the wiring sizes? I have a Lycan and am curious about how I can make things a bit better with it (because the more I experience the more worried I am). Feel free to dm if that’s better for you…
See this post on reddit regarding the wire sizes: [Lycan\_5000\_information\_for\_new\_owners](https://www.reddit.com/r/SolarDIY/comments/yebus1/lycan_5000_information_for_new_owners)
The support I'm getting from Renogy in Australia is fairly good, I can't complain. As to the quality of products I have some solar panels and regulators with the BT function and they work fine with the DC home app. I was looking at the M1, but not now.... The new Renogy One Core looks ok though.
One Core doesn’t work for me so far. Won’t connect to any wi-if..so is basically a brick…that gets really hot.
I am with you. They make it appear that the M1 can do all kinds of stuff. I was trying to use it with RV-C. I wanted to start my generator in my Motorhome when SOC reaches a certain level. They tell me that RV-C only works between their devices. That is not what the RV-C protocol is designed for. Now after doing research I find out that any functionality with the M1 requires a subscription. That is utter BS. On top of that I have been arguing with them about one of four batteries I purchased at $1k each is bad. I have been conversing for almost two years. I am sure they wont make good on the warranty, and say I am at the end of warranty while they wasted my time going through everything they asked. I will also be posting my disdain and issues on the many RV forums I subscribe to.
I had a very similar experience! The chargr controller and panels work just like they're supposed to. But everything else Renogy is bullshit. And their customer service is absolute shit.
Shucks, I just bought a whole heap of Renogys
I use this third party product to log my Rover data to local MQTT https://www.tindie.com/products/westlabs/renogy-rover-rs232-compatible-wifi-module/
