📏 Before you order:

The SUNON7.2 is an off-grid inverter. It can charge from the grid or a generator, but it doesn't export power to the utility.
Need more than 7.2kW? Look at our SUNON12 + Lithi2-16 system, or add a second SUNON7.2 in parallel later.
The cabinet ships by freight. Residential and liftgate delivery may add a fee.
We recommend installation by a qualified electrician.

Choose Your System

Every system includes the 6-slot cabinet, so you can add batteries later up to six.

Why This System

⚡

Real 240V Power

Split-phase 120/240V output runs well pumps, dryers and other 240V equipment, not just 120V outlets.

☀️

Dual MPPT Solar

Two MPPT inputs take up to 9,000W of solar for faster battery charging.

🗄️

Clean, Protected Bank

RUiXU's pre-assembled cabinet holds up to six batteries with the busbar and wheels already in place.

📈

Room to Grow

Start with three batteries and fill the cabinet later, or parallel up to six SUNON7.2 inverters.
