RPI M8A

Product catalog summary

Overview: The RPI M8A is a high-efficiency, 3-phase transformerless inverter designed for the European market, suitable for residential or small commercial photovoltaic (PV) systems. It features a compact design with a high power density-to-size ratio, making it ideal for versatile applications both indoors and outdoors.

Specifications:

Efficiency: Maximum efficiency of 98.3% and EU efficiency of 97.9%.
Operating Conditions: Temperature range from -25°C to +60°C, with full power operation without derating up to +40°C. Humidity tolerance is 0-100% non-condensing, and it can operate at altitudes up to 2000 meters.
Output (AC): Nominal apparent power of 8.0 kVA, voltage range of 230 ± 20% / 400 V ± 20%, and a nominal frequency of 50/60 Hz. The power factor is adjustable between 0.8 capacitive and 0.8 inductive, with total harmonic distortion (THD) less than 3%.
Input (DC): Maximum recommended PV power is 10 kWP, with a voltage range of 200 to 1000 V and a startup voltage of 250 V. It supports symmetrical and asymmetrical loads with two MPP trackers.

Design and Features:

Mechanical Design: The inverter measures 510 x 445 x 117 mm and weighs 25 kg. It uses convection cooling and includes integrated AC/DC disconnectors.
Safety and Standards: The inverter complies with various safety and grid regulations, including VDE, EN, and IEC standards. It features configurable trip parameters, insulation monitoring, and anti-islanding protection.
Communication: Equipped with multiple communication interfaces, including RS485, dry contact, emergency power-off, and digital inputs.
