I am planning to build a simple 12V solar system for my grandkids playhouse. I have a 265W Qcell panel with short circuit current 9.32A and open circuit voltage 38.52V. Would a 10A mppt controller work for my project? Any recommendations on make/model? Thank you in advance, Leonid

I believe the charger has everything “for dummies”: About this item INTELLIGENT REGULATOR : Compatible with 12v/24v batteries(SLD/FLD/GEL/LiFePO4/ternary lithium battery), this solar charge controller is auto resettable after disconnecting, also be auto-wakeup for lithium battery after...

I have not chosen a battery yet, thinking of something like 20-50 Ah sealed. The system will be used mostly if not only for lighting. With modern 12V led I won’t need too much power. I got confused with the max panel current of 9A. Is mppt able to produce more charge current to battery than the...

It is almost done. Thanks to everyone for your advice. I bought 16Ah LiFePo and 20A PWM. Small size and weight were what I liked.

I tested my setup. I discharged the battery to under 20% and placed the panel under the bright sun. The controller displayed up to 6A and went down to 0.1A in about 6 hrs. It looks like a very reasonable charging mode.

Is EPEVER 20A MPPT Charge Controller 12V 24V a good one? It is the only 20A controller currently available on Amazon Prime with 2-days delivery.

I was advised by the other people that I need 20A for the 265W panel. Won't 10A charger fail or just limit charging by 10A? Thanks!
