ONE Core: All-in-one Off-Grid Energy Monitoring Panel, Battery Monitoring for Van, Cabin, Boat and Tiny Homes, Works with Renogy Energy Devices, Wi-Fi Version, Black

Works great just don’t hook to battery bank with lots of amps it will overheat it

Got mine in October of 2025 and it only lasted till April 2026. The display is unresponsive, I checked the voltage to the unit and it was 13.4 volts. Tried reseting nothing helped! So I just installed the second one we’ll see how long this one lasts🤬

Connected to phone, love the fact that I can monitor anywhere. Installing it was ok, took a few, but got it figured out.

Not very easy to setup and link. I like the size and screen looks good, just spent 3 days getting the think linked with my phone app. Thank goodness for YouTube and google. If your dedicated to making it work, there is a lot of info out there, that supports the product, better than Renogy’s manual’s, on screen setup guidelines, etc..

Renogy keeps getting better everyday. I have 2 of these; 1 in my camper and 1 in the tool trailer. Great product for monitoring your batteries and solar components.

hopefully getting the attention of renogy because they are sending out this stuff without the comm cable. Classic renogy man they are so close to being great but clearly dont give a f about their customers. I am in too deep at this point with two systems but I would not recommend them to anyone.

Remember this is a WiFi device, plug in using usb c plug and update and connect to wifi before install. Trying to do it from RV can be a pain because of signal strength. I bought this to have wifi control over my RV system. if you just want bluetooth use the phone app. I have 800 watts solar, rover 60 controller, shunt300, and 600AH of batteries. All is Renogy. Easy to install just make sure your trailer is level and when installing mount pay attention to the bubble level. once done press calibrate button on your phone to calibrate to zero. I was .2 degrees side to side and .8 end to end but it was good enough to be considered level. hit calibrate and it says 0 in both directions. awesome product for the price. the only thing better is Victor electronics at 3 times the price.

Find something else. Less than one week after installing this device a software update made it useless. Now I have a hole in the wall to go along with my return paperwork. I should also mention they removed the leveling function from the software. UPDATE: Renogy support got it working again, but the idea that it could become useless mce again overnight is still around.
