RPI M50A

Product catalog summary

Overview: The RPI M50A is a high-efficiency, 3-phase solar inverter designed for large-scale solar PV systems in the European market, suitable for commercial and agricultural sectors. It features a compact design, high power density, and versatile applications for both indoor and outdoor use.

Specifications: The inverter offers a peak efficiency of 98.6% and an EU efficiency of 98.4%. It operates within a temperature range of -25 to +60 °C and supports a maximum operating altitude of 2000 meters. The standard guarantee is 5 years, with possible extensions.

Output (AC): The inverter provides a nominal apparent power of 50 kVA, with a maximum of 55 kVA. It supports a voltage range of 230 ± 20% / 400 V ± 20% and a frequency range of 50/60 Hz ± 5 Hz. The power factor is adjustable between 0.8 capacitive and 0.8 inductive, with a total harmonic distortion of less than 3% at nominal power.

Safety and Standards: The RPI M50A complies with various safety and grid regulations, including VDE, UTE, G59/3 LV, and EMC standards. It features IP65 protection, safety class I, configurable trip parameters, insulation monitoring, and anti-islanding protection.

Input (DC): The inverter supports a maximum recommended PV power of 70 kWP and a maximum input power of 58 kW. It operates within a voltage range of 200 to 1100 V, with a maximum current of 100 A. It includes two MPP trackers for symmetrical and asymmetrical loading.

Mechanical Design: The inverter measures 740 x 612 x 278 mm and weighs 74 kg. It includes cooling fans, AC and DC connectors, communication interfaces, and an integrated DC disconnector. The display features two LEDs and a 4-line LCD.

Model Variants: The RPI M50A is available in two models: M50A_120 with integrated AC and DC surge protection devices (SPDs) and M50A_122 without SPDs.
