1.22kW Off-Grid Tiny House Solar Power System (Base Kit 2)

This off-grid solar power system kit provides nearly everything you need to bring 1.22kW of off-grid solar power and storage to a tiny house off the grid. Choose your preferred battery type and solar panel mounting option, and you're on your way!

The inverter/charger at the heart of this system is a Samlex EVO-2224, capable of delivering 2.2kW continuously over 120-volt pure sine wave AC output. As a 24V battery bank charger, the EVO-2224 offers adaptive 3- or 4-stage charging with equalization. And with two programmable AC inputs, a generator can easily be added to this system. Working in tandem with the EVO-2224 is a FLEXmax 60 MPPT Charge Controller from OutBack Power, which provides up to 60 amps of 5-stage battery charging from your solar panels.

For Installation You May Need to Provide:

• Multimeter
• Tools for installation
• Wiring between combiner or junction box and inverter or charge controller
• Wire terminals
• Pass-through bushings
• Conduit
• Lag bolts for mounting racking to roof (if Roof Mounting Option is chosen)
• Schedule 40 piping (if Ground or Top of Pole Mounting Option is chosen)
• Concrete for anchoring (if Ground or Top of Pole Mounting Option is chosen)

The answer starts with knowing how much power you need on a daily basis in kilowatt-hours (our load calculator can help with this; divide the number it gives you in Watt-hours by 1000 to get kilowatt-hours, or kWh).

Compare your daily kWh needs to the map here, which shows the amount of daily kWh this system's solar panels will produce if installed at an optimal tilt during the time of year when there's the least amount of sun. If your needs exceed the solar potential shown for your area on the map, check out our larger off-grid solar power system kits.
