RiiO Sun II series is a brand-new versatile all-in-one solar inverter for off-grid, energy storage systems and self-consumption applications, combining a pure sine wave inverter, battery charger, MPPT solar charge controller and a high-speed automatic transfer switch in a compact casing with a user friendly display.

Compared with the previous RiiO Sun series, it boasts higher PV open circuit voltage, higher PV charging power and current, and supports parallel and three-phase operation up to 9 units to achieve higher power output (up to 72kVA).

It is optional to work without battery and only use solar energy to power loads directly.

You can start with a smaller system and gradually expand, depending on what best suits your needs and budget..

RiiO Sun II supports energy feeding back to power loads on the AC input to maximize self-consumption and cut down system investment.

Auto generator start function is also available for RiiO Sun II. Its power assist and power control function enable it to work well with limited AC sources such as generators or limited grid.

RiiO Sun II can automatically adjust its charging current by taking loads into account to protect the AC source from overload.
