Deye SUN-100K-G03 String Inverter 100kW Three-Phase
The Deye SUN-100K-G03 is a three-phase string inverter rated 100kW for grid-feeding PV plants on industrial roofs, carports and ground-mounted fields. With 6 MPP trackers, up to 150kW of PV input power and a peak efficiency of 98.8%, it is the reference machine for projects without storage that need maximum yield per installed kWp.
The IP65 enclosure with intelligent air cooling and noise below 55 dB allow outdoor installation even close to working areas. Type II surge protection on both DC and AC, optional AFCI and CEI 0-21 and CEI 0-16 certification make grid connection in Italy straightforward. It pairs with Deye loggers and meters for export power control and, within the same plant, with Deye hybrid inverters for the storage section.
