RSI31 Micro Inverter

RSI31 Solar Micro Inverter features switchable single-phase and three-phase AC voltage, real-time data monitoring, and support for four solar modules. Its durable, IP65 waterproof design, high-speed MicroChip CPU, and multi-channel MPPT controller ensure efficient and reliable performance.

Features of RSI31 Micro Inverter

◆ Switchable single-phase and three-phase AC voltage

◆ Real-time/historical data monitoring and analysis

◆ Each unit can connect 4 solar modules

◆ Streamlined appearance/Acid and alkali resistance and oxidation resistance, High-quality aluminum alloy casing, High-pressure oxidation treatment process, IP65 waterproof design;

◆ MicroChip CPU: High-speed digital processing chip, More stable operation; Multiple PWM outputs, Large number processing;

◆4-channel MPPT controller: Multi-channel maximum power point tracking (MPPT) Capture solar light with high speed and precision, Let photovoltaic systems generate more power and be more efficient;

◆ LLCPower chip management: High performance PWM controller, Everything is under your control, dual-ended full-bridge topology;

◆ Stacked installation of multiple inverters: Multiple inverters of different models can be stacked and installed, Installation and connection are simple and quick; The current of each group connected in series to the AC box can reach 50 Amp;

◆ Multiple single-string stacking: No model limit, match as you like, and work independently without interfering with each other. The branches of the system work independently. Even if a certain path or a certain pile is damaged, it can continue to work.
