Deye GB-S15K-EU Hybrid Inverter 15 kW Three-Phase High Voltage All-in-One
The Deye GB-S15K-EU is the 15 kW three-phase conversion unit of the GB-S high voltage All-in-One storage platform. It simultaneously manages the PV array (up to 19,500 W across 2 MPPT trackers with DC voltage up to 1,000 V), the high voltage battery and the grid, allowing on-grid, off-grid and generator operation and keeping essential loads powered during a grid outage.
It is designed for homes with high consumption and for small commercial premises: heat pumps, electric vehicle charging and unbalanced loads across the three phases. The IP65 protection rating 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 together with their BMS unit and base, communicating with the BMS via CAN; capacity is expanded by adding modules in series.
Key features
15 kW Three-PhaseRated output of 15,000 W across three phases at 230/400 V, with 16.5 kW of maximum AC power and unbalanced load handling up to 30 A.
DC Side up to 1,000 VTwo MPPT trackers with a 150-850 V range and 19,500 W of accepted PV power: suitable for roof pitches with different orientations and for generous array oversizing.
High Voltage StorageWorks with LiFePO4 battery packs from 160 to 700 V (Deye GB-L Pro Pack 4.1 HV), modular and expandable by adding modules in series.
High EfficiencyMaximum efficiency of 97.6 % and European efficiency of 97 %, with 99.9 % MPPT tracking efficiency.
Off-Grid and Generator OperationSupports on-grid, off-grid and generator set operation, keeping critical loads powered during a blackout.
Sheltered IP65 InstallationIP65 enclosure with intelligent thermal management and built-in protections against overvoltage, overcurrent, short circuit and insulation faults.
