Review on 🌞 Renogy Commander 40 Amp 12V/24V MPPT Negative Ground Solar Charge Controller Regulator - Compatible with Sealed Lead-Acid, Flooded, Gel Batteries + MT-50 Tracer Meter by Sean Julian

Died 2.5 years in the best generators and portable power supplies

update my review: seemed like a great controller but only 1 year warranty. Since the installation I have generated over 1750 kWh of electricity with it and 10x100 watt solar panels. Everything worked as expected, but after 2.5 years the switch between battery and controller tripped and works again when I restart. The controller ended up with a short on the charging side. I regularly connect my laptop to it and study logs to see how the panels work and it works very efficiently. I have a 48v 188ah battery system, i have this charger and it keeps them well charged. The only problem is that I don't think the software can be easily installed by a non-computer technician, and it can't turn loads on and off. I bought it for around $400 so I thought it was a great price compared to other big brands.

Pros
  • handy thing
Cons
  • useless features
