FoxESS P3-100-Plus Commercial String Inverter 100kW Three-phase 8 MPPT
The FoxESS P3-100-Plus is a three-phase string inverter rated 100kW from the P3 Plus series, built for commercial and industrial plants. Maximum apparent power is 110kVA, with 152A rated and 167,2A maximum current per phase, and the unit runs 8 MPP trackers.
Peak efficiency is 98.5% and European efficiency 98.1%. Maximum DC voltage is 1000V with a 180-850V MPPT window; power factor is adjustable from 0.8 leading to 0.8 lagging and current distortion stays below 3% at rated power, as required for medium-voltage connections.
Cooling is intelligent air cooling, the enclosure is IP65 and the operating range spans -30 to +60 °C up to 4000 m altitude. Communication ports include USB, RS485, Bluetooth, Wi-Fi and LAN, with optional 4G and CAN, so the inverter fits into plant supervision systems.
