Description:
The PIS‑50/500‑T is a 50 kVA string solar inverter designed for medium‑scale photovoltaic installations. It converts DC power from solar arrays into high‑quality AC power for feeding into the grid. The inverter employs a three‑level IGBT conversion circuit with RB‑IGBTs (reverse‑blocking IGBTs) to reduce switching losses, harmonic distortion and noise, achieving a maximum conversion efficiency of 99.0% (Euro efficiency 98.5%). The unit is housed in an IP65‑rated outdoor enclosure, rated for ambient temperatures from –25 °C to +60 °C, and includes both passive and active anti‑islanding detection, voltage ride‑through (FRT) capability, and a RS‑485 communication interface. It is designed for no‑isolation‑transformer operation and can be installed indoors or outdoors.
