The ESS1-15K3P-02-HV is a three-phase hybrid inverter built for villas, small factories and commercial buildings that need solar self-consumption and battery backup on a three-phase supply. It manages the PV array, a high-voltage LiFePO4 battery bank and the grid from one unit, feeding loads first and storing or exporting the surplus according to programmable priorities.
Key Features
- Three-phase hybrid: 15kW output at 380-400VAC within a 10-30kW series.
- High-voltage battery bus: lower charge/discharge currents improve round-trip efficiency and simplify cabling.
- Quality cells: pairs with HV LiFePO4 battery modules using CATL/EVE cells.
- Dual MPPT: wide PV voltage window for flexible string design.
- Uninterruptible backup: automatic switchover fast enough to keep computers and control systems running.
- Tested before dispatch: every unit completes a 72-hour full-load test; LCD plus monitoring app included.
Typical Applications
Villas, small factories and commercial buildings with three-phase supplies and daily loads around 60-100kWh; multiple units parallel for larger C&I sites.
Common Pain Points We Solve
- Backup complexity on three-phase: PV, HV battery and grid managed by one unit – no external transfer switches or custom control wiring.
- Downtime for critical loads: automatic switchover is fast enough to keep computers and control systems running through outages.
- Quality uncertainty: every unit completes a 72-hour full-load test before dispatch – failures happen in our factory, not on your site.
- Scalability doubts: parallel operation with HV battery modules lets the same platform grow from a villa to a C&I plant.
