I hope someone has an answer for this. My 4x 100W Renogy solar panels in series and my new MPPT solar controller (EPEVER 40A/150V) will take two hours in the morning to output any meaningful voltage and current. For instance, at 9AM with *full* Sun exposure here in Arizona, the MT50 digital...

When using my 60A PWM solar charge controller (model BSC6048) on the “LiFePO4: 3.2V-4S” setting versus the controller’s other LiFePO4 setting of “3.2V-5S”, I only get half the charging current (10A) to my two parallel BB 12V batteries with my 4 x 100W parallel connected solar panels. In other...

We just set up your Renogy solar system for our RV. It consists of four Renogy 100W 12V Monocrystalline Solar Panels, wired (10AWG) in parallel to a Renogy Wanderer Li 30A 12V PWM NG Charge Controller, then on to our twin 100Ah BB 12V Lithium batteries (in parallel). We are in Arizona (White...
