📏 Before you order:

The SUNON3.6 delivers 120V single-phase power. If you need 240V for a well pump, dryer or central AC, look at the SUNON7.2 system instead.
Keep your solar array within 4,500W and 300V open-circuit.
It's an off-grid inverter. It can charge from the grid or a generator, but it doesn't export power to the utility.
Need more power later? Up to 6 SUNON3.6 units can run in parallel.

❓ Common Questions

Will it run my well pump or AC?

The SUNON3.6 is 120V only and rated for motors up to 2 HP. Many well pumps and central AC units need 240V. If yours does, choose our SUNON7.2 system instead.

Can I add batteries later?

Yes. Add more RX-LFP48100 batteries and bracket racks anytime. The included RX10P busbar has room for a larger bank.

Can I add a generator?

Yes. The SUNON3.6 can charge your batteries from a generator at up to 40A.

How is it delivered?
