Thanks for these updates. I was considering the Epever MPPT options when I had gotten sick and tired of trying to get Renogy support to help me figure out if the Renogy Rover MPPT I had was defective or simply really really poorly designed. After weeks of back and forth with them (they never answered my questions and kept me looping by repeatedly asking for the same information like screenshots which I sent to them more than once, “read the this t support thread” is what i told them). After hearing about
@Rednecktek ’s MPPT dropping issues with Epevers, I knew that for not an extreme amount of more money I could get a Victron 100/30 and NEVER DEAL WITH THIS SHIT AGAIN. So I did and so far, I haven’t had to deal with any of that shit. In fact, I think the MPPT tracking on my Victron is so fast, that I’m seeing 15-30% more production using the exact same panels as I used with the Renogy. Based upon reports like yours and Rednecktek, I assume it might be a similar problem with the Epever since it’s getting stuck.
@sunshine_eggo summed it up when he said that the solar charge controller is the brain of your whole system, so why would you go cheap? What’s the benefit of an inferior brain? Buy a cheap battery, cheap panels, quality aka expensive copper wiring and good connectors and a quality not-cheap charge controller. That will be a good investment.
Wish I could get back all the time I “wasted” learning this lesson, lol!
Not saying they’re isn’ta time and place for cheap charge controllers, even the $7 PWM ones have their use case. But if it’s important that your controller works as well as you think it should and not give you headaches, then spend a day as a panhandler or whatever it takes to pony up to buy a quality one.
