What it covers
Panel side: four 100 W panels wired two in series, two strings in parallel. Panel voltage stays under the controller’s 100 V limit with room left for cold mornings, and 400 W is under the controller’s 440 W rating at 12 V. AC side: the inverter supplies 800 VA, or 650 W at 25 C (1,500 W peak). Check the watts on each device’s label.
