Deye GB-S20K-EU Hybrid Inverter 20 kW Three-Phase High Voltage All-in-One
The Deye GB-S20K-EU is the 20 kW three-phase size of the GB-S high voltage All-in-One storage platform. It accepts up to 26,000 W of PV across two MPPT trackers with a 1,000 V DC side, manages the high voltage battery pack and the grid connection, with on-grid, off-grid and generator set operation.
It suits small commercial installations, branch premises and homes with high annual consumption, where a heat pump, electric vehicle charging and technical loads have to be powered at the same time, even with unbalanced loads across the phases (up to 35 A). The IP65 enclosure allows indoor installation or outdoor installation in a sheltered position. It pairs with Deye GB-L Pro Pack 4.1 high voltage LiFePO4 battery modules with dedicated BMS unit and base, with CAN communication and capacity expandable module by module.
Key features
20 kW Three-PhaseRated output of 20,000 W and maximum AC power of 22,000 W on a 230/400 V grid, with a rated current of 30.4 A.
Unbalanced Loads up to 35 AHandles uneven load distribution across the three phases, a common situation in residential installations and small businesses.
26 kW of PV on 2 MPPTsMPPT range of 150-850 V and maximum DC voltage of 1,000 V, with 26+26 A of input current: suitable for large roof areas.
Modular High Voltage StorageWorks with LiFePO4 packs from 160 to 700 V; capacity grows by adding GB-L Pro Pack modules in series.
Efficiency up to 97.6 %Maximum efficiency of 97.6 %, European efficiency of 97 % and MPPT tracking efficiency of 99.9 %.
Continuity of SupplyOff-grid operation powering essential loads during a blackout, with the option of integrating a generator.
