TBB RiiOSun II 2kVA~8kVA all in one solar inverter

RiiO Sun II series is TBB’s brand-new versatile all-in-one solar inverter for off-grid, ESS 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 better display interface design and better human machine interface. 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 54KVA). It is optional to work without battery and only use solar energy to power loads directly. You can start

with the comprehensive system or a smaller solution and gradually expand it, depending on what best suits your needs and budget. A

programmable smart port is also equipped in both 5KVA and 6KVA model for generator input or load management.

Worth to mention, that RiiO Sun II supports energy feeding back to power loads on the AC input to maximize self-consumption and cut

down system investment. AGS function now is also available for RiiO Sun II. Its power assist and power control function enable it 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. Once the temporary peak power appears, it can also discharge the battery in an

extremely short time to compensate the insufficient part of the limited AC source.
