I am looking for a charge controller for one or two sun panels (each ~ 400 Wp) to charge a proper 12 V BMS+LiFePO4 battery in a cost effective but reliable way.
This seems to be a very simple question. However, I am a bit lost here, having found so many answers with caveats like "very expensive" and "unreliable".
For example, this article scares me to choose MakeSkyBlue MPPT or its clone PowMR. Epever MPPT seems a bit less scaring. Or is using PWM a good choice for small scale projects?
I would really appreciate getting some practical user experiences, some thoughts. Thanks!
