Questions & Answers
Is this a genuine original part?
This is a premium quality professional-grade inverter from TBB Power, supplied by Solarika. It is built to industrial standards for long-term off-grid and backup use.
How do I know if it is compatible?
Check that your battery bank is 48V. If you are using solar panels, ensure the total VOC (Open Circuit Voltage) does not exceed the 250V limit for this RIIO-II series model.
Can this inverter work without a battery?
The RIIO-II series is designed as a hybrid system; while it can support loads directly from solar when the grid is present, a battery is highly recommended for stable off-grid operation and to leverage its full surge capacity.
