Browse Components
Batteries
LiFePO4 batteries from 100Ah to 300Ah. Compare voltage, capacity, cycle life, and price per watt-hour.
Charge Controllers
MPPT and PWM charge controllers. Match solar input voltage, charge amps, and battery compatibility.
Inverters
Pure sine wave inverters from 1000W to 6000W. Compare input voltage, surge watts, and efficiency.
Solar Panels
Rigid and flexible solar panels. Compare wattage, Voc, Vmp, and price per watt.
How It Works
Size your system
Add up the watt-hours you need per day. Account for weather, inefficiency, and days of autonomy.
Pick compatible components
Match battery voltage to your charge controller and inverter. Check solar panel Voc against controller limits.
Wire it up
Connect panels to controller, controller to batteries, batteries to inverter. Use proper fusing and wire gauge.
