HS3-12K-T2-W-P is SAJ's latest-generation three-phase all-in-one system. In an enclosure only 170 mm deep, it combines a hybrid inverter (PCS), BMS, energy management system (EMS), battery modules and, optionally, an 11 kW EV charger. The modules use plug-in connections with no visible cabling, and the entire installation requires only 12 screws.
Key benefits
- Each battery module has its own DC/DC optimiser, allowing the system to be expanded with new modules at any time, regardless of the age of existing modules
- Input current up to 20 A per string, suitable for large-format modules
- Expandable to 8 battery modules (40 kWh)
- Cable-free plug-in connection between modules
- Internal battery self-heating and fire protection
- Optionally integrated 11 kW EV charger (CU2-11K-T-I)
- Only 170 mm deep with IP65
