Deye GB-S20K-EU Hybrid Inverter 20kW Three-Phase High Voltage All-in-One

The Deye GB-S20K-EU is the 20kW three-phase hybrid inverter of the Deye high-voltage all-in-one storage system: it handles up to 26kW of PV on 2 MPPTs and a high-voltage battery pack in the 160-700V range, built from stackable Deye GB-LM4.0 modules of 4.09kWh. It is the answer for three-phase homes, shops and small businesses looking for self-consumption, storage and backup in a single cabinet.

The high-voltage architecture lowers currents and therefore cable losses: peak efficiency is 97.6% with 99.9% MPPT efficiency. A generator input and unbalanced-output handling also suit weak grids, while CAN communication with the BMS and CEI 0-21 compliance simplify installation in Italy. Monitoring runs through the Deye DL1000B data loggers on Deye Cloud.

Key features

160-700V high-voltage batteryThe high-voltage pack built from 4.09kWh GB-LM4.0 modules cuts currents and cable losses compared with a 48V system.
20kW three-phase with 2 MPPTsTwo MPP trackers of 26A each accept up to 26kW of modules and cover two different orientations.
97.6% efficiency97.6% peak efficiency, 97% European efficiency and 99.9% MPPT efficiency.
Generator and unbalanced gridsA dedicated generator input and unbalanced-load handling, with CEI 0-21 and VDE-AR-N 4105 compliance.
