RPI Series 15-20 kVA

Thеsе new three-phase transformerless solar inverters are designed for commercial PV applications where maximum versatility and profitability are important. Thanks to the high maximum efficiency up to 98.4 %, optimum yield from the PV plant is ensured from the devices.

For the system planner, maximum flexibility is ensured thanks to a wide input voltage range of 200 – 1000 V and 2 MPP trackers. The RPI series support symmetrical and asymmetrical loading (33/67 %). The new units are compatible with major types of PV modules and the robust IP65 rated enclosure allows outdoor installation.

The M50A Inverter has built-in and replaceable AC and DC-side Type II SPDs (surge protection devices) and 15 A string fuses. The M50A offers an exceptional power density-to-size ratio, one of the highest in the 50 kVA transformerless inverter class. The aluminium housing ensures long lasting protection against moisture and corrosion and is suitable for indoor and outdoor applications (IP65).
