      RiiO Sun II (HV)

      2kVA-8kVA

      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. 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 a battery and only use solar energy to power loads directly. A programmable smart port is also equipped in 5kVA, 6kVA, and 8kVA models for generator input or load management.

      Parallel & Three-phase Operation up to 9 units

      RiiO Sun II supports parallel and three-phase operation up to 9 units to achieve higher power output (up to 72kVA). You can start with the comprehensive system or a smaller solution and gradually expand it, depending on what best suits your needs and budget.

      Optional to work without battery

      Optional to work without battery

      Only for single unit applications with stable AC bypass supply, and PV energy is a supplement for AC bypass. The energy produced by the solar panels is directed to the house for use and they do not need to produce all the electricity to run an entire household as shortfalls can be made up from the grid. Advantages of working without battery backup: savings on electricity bills, less costly to install, more environmentally friendly, fewer components to maintain.

      A programmable smart port

      A programmable smart port

      Built-in a programmable smart port for generator input or power normal loads. When programmed as generator input, it can provide two AC inputs for the system; When it is programmed as an AC out 2 for connecting normal loads, its on/off can be controlled based on the grid condition, battery SoC/Voltage, to manage loads in a smart way.
