📏 Before you order:

Grid-tied systems need utility interconnection approval and a permit. Talk to your installer and utility first.
Keep solar strings within the RX-12K's 90–550V PV input range.
For off-grid properties without utility power, see our SUNON12 + Lithi2-16 off-grid system.
Installation by a licensed electrician is required for grid-tied systems in most areas.

❓ Common Questions

What's the difference between this and the SUNON12 system?

The RX-12K is a hybrid inverter for homes connected to the utility. It works with the grid and backs you up in an outage. The SUNON12 system is built for off-grid properties.

Will it back up my whole house?

It depends on your loads. The RX-12K delivers 11.4kW continuous, which covers most homes. Send us your main loads and we'll help you check.

Can I add more batteries later?

Yes. RUiXU supports up to 32 Lithi2-16 batteries in parallel.

How is it delivered?

By freight from RUiXU's California warehouse. Residential and liftgate delivery may add a fee, and we'll confirm the details before shipping.
