Review on 🌞 Renogy 48V 3500W All-in-One Pure Sine Wave Inverter with MPPT Charge Controller – Solar Power for Home, Camping, and RVs by Bill Dahl

I ordered one of these as an incentive to retrofit the solar system in my motorhome. I have had many solar panels with an open voltage of around 130 volts. The camper also has a 4000w generator. The idea was to use a solar inverter to extend my dry camping time before running out of gas or needing to change the motor oil in my generator. The problem I had was that the charge control circuitry was defective/faulty or too picky. If at any point it fails for any reason, the generator just happens to stall for half a second too, stopping charging entirely. After that, it will no longer charge from the 120V input and will completely drain $1,000 AGM interstate batteries. The only way to get it working again was to turn it off and turn off the power for over an hour and then miraculously when the power came back on it worked. At least until the generator tripped or something stupid happened again and I then tried again to get it to charge its batteries. Worse, I ran into a situation a couple of times where even with the solar power generator on, everything was on. the inverter did not turn on. No error codes just no power delivery but with the power lights on and everything lit as normal on the unit power button, tried all the options under the sun, same result, no power. I showed that the inverter is off. It just won't kick the inverter. Turn off the generator, the power suddenly turns on. Maybe a bad bypass? I got him to say it was in bypass mode and worked exactly as it should once and never again after that. I'm tired of fighting this and if it happened while I was out I'd be in trouble. I work remotely while I'm on the road. I sent it back. After some research, it turned out that most of the cheap all-in-ones on the market are now made by the same company, SRNE. Renogy is just a rebrand, in this case it looks like they've rebranded the buggy old hardware and are charging more than other companies for the latest LCD upgrade versions. This strengthened my decision, unfortunately I had to send it back. Revain don't have the latest Growatt 3000TL LVM-ES (yet), they only have older ones that have literally the same LCD screen etc as Renogy. The Growatt I ordered elsewhere stacks up to six units. It only has good reviews on YouTube, renogy 48v 3500 watt only has bad reviews on YouTube. Revain really should stop selling it. I wish I hadn't wasted my time on that half-baked solar inverter and doing some research and ordering some first-timers on the way.
