SAJ HS2
The SAJ All-in-One three-phase solution is the first comprehensive home energy storage system, combining an integrated hybrid inverter (PCS), a battery management module (BMS) and an energy storage unit. This series features a modular design, IP65 ingress protection rating and no external wiring, ensuring extremely simple and fast installation. The devices offer power from 5 to 10 kW, 2 MPPT trackers and full support for three-phase unbalanced loads.
Key features of SAJ HS2:
- All-in-One and modular design: Integrated inverter, BMS and battery with the ability to expand battery capacity up to 25 kWh (using BU2-5.0-HV1/5 modules).
- High performance and compatibility: Support for DC input current up to 16 A per MPPT, providing excellent matching with modern high-power photovoltaic panels.
- UPS emergency power: Reliable switching function with a time below 10 ms ensures continuity of power in case of grid loss.
- Three-phase unbalanced load: Full support for three-phase unbalanced loads and maximum efficiency up to 98.0%.
- Weather resistance: IP65 ingress protection rating and cooling by natural convection allow flexible installation locations.
- Safety and flexibility: Provides comprehensive electrical protections, AC retrofit function and quiet operation below 35 dBA.
Who is this a good choice for?
The SAJ HS2 series is an ideal solution for single-family homeowners seeking a modern, aesthetic and fully integrated photovoltaic system with energy storage. With a wide power range from 5 to 10 kW, three-phase supply and UPS function, the system is suitable wherever energy security, independence from the grid and ease of future system expansion are key.
