      RiiO Sun II (LV&SP) solar inverter for backup power applications product features

      RiiO Sun II (LV & SP)

      All-in-one Solar Inverter

      RiiO Sun II (LV & SP)

      Single Phase: 2kVA / 3kVA / 4kVA | 120VAC Split Phase: 5kVA / 8kVA | 120/240VAC

      RiiO Sun II is a versatile transformer-based all-in-one solar inverter, designed for backup power, off-grid and ESS applications, integrating a pure sine wave inverter, battery charger, MPPT solar charge controller and a rapid 4ms automatic transfer switch in a compact casing. It’s engineered to handle high surge loads and ensures continuous operation of critical load during outages. Additionally, RiiO Sun II enhances energy self-consumption, supports grid feed-in for utility credits and retrofing existing PV system, and optimizes costs with peak shaving and time-of-use strategies.

      2 MPPT trackers for flexible system installation

      Dual-MPPT functionality allows much greater system design flexibility, significant cost savings and higher levels of harvested energy.

      Parallel & Three-phase Operation up to 9 units

      Parallel & Three-phase Operation up to 9 units

      RiiO Sun II supports parallel and three-phase (SP only supports parallel) operation up to 9 units to achieve higher power output (up to 36kVA). 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.
