we recommend to choose solar panel that meets below:
1) open circuit voltage between 35-150v(OCV, whatever you connect the panel in series or in parallel), Max.700W, Max.12A
2) MC4 Connector (if your solar panel has an anderson connector, you need to buy a anderson to mc4 charging cable)
Note:total OCV below 35V or above 150V will trigger low-voltage/over-voltage protection. AC200P only receive 700W/12A(Max.) if total input power /current exceed 700W/12A.
The recharge time various from diffrent factors such as weather condition, the actual input solar power, temperature, angle, etc.
