High-capacity three-phase storage, purpose-built for Force H3X.
The Pylontech FH3X-15K-HY-3P is a 15 kW three-phase high-voltage hybrid inverter designed to sit on top of Force H3X battery stacks. It supports seamless on-/off-grid operation with fast EPS switchover, generous PV headroom, and native connectivity for smart energy management. (Listing is for the inverter head unit only—battery modules, cabinet and accessories sold separately.)

Why installers choose it

• Serious PV flexibility: up to 24 kW PV, 3 MPPT (1+1+1), MPPT 200–850 V (full-load 280–850 V), Voc 1000 V, 20 A per MPPT (Isc 30 A). Ideal for modern high-voltage strings.

• High-voltage battery performance: works with Force H3X stacks (system 120–850 V) with up to 50 A charge / 50 A discharge on the 15 kW model.

• Fast backup (EPS): on/off-grid switching ≤10 ms keeps essential loads powered.

• Scalable power: parallel up to 6 three-phase units for higher power and redundancy. 

Reliability & compliance

• Outdoor-ready protection: system IP55; DC/AC SPD Type II; AFCI; engineered for EU grid/safety norms including EN 50549-1, VDE-AR-N 4105, CEI 0-21 (see datasheet). 

• Low noise, wide climate window: air cooling, <29 dB @1 m, operating –10 °C to +55 °C.

Monitoring & comms

Built-in Wi-Fi/WLAN/Bluetooth portal connectivity, plus RS485/CAN for inverter-to-BMS and external integrations.

Efficiency

European efficiency ~97%; max efficiency up to ~97.6% for the three-phase range.
