The SAJ HS5 EK70 is a premium all-in-one solar and battery storage solution combining a high-performance hybrid inverter, modular 9kWh LiFePO4 battery storage, whole-home backup and intelligent energy management in one streamlined system.


Available in both single-phase and three-phase configurations, the HS5 EK70 is designed for fast installation, flexible system sizing and reliable backup power. Its modular blind-mate design minimises external battery cabling while the integrated 63A bypass and automatic transfer functionality simplify whole-home backup without the need for a separate backup gateway.


Each 9kWh battery module uses premium 314Ah LiFePO4 cells and provides 9kWh of usable capacity with 100% depth of discharge. Up to six battery modules can be connected per system, providing up to 54kWh of storage capacity. Individual DC/DC optimisation allows each battery module to be independently managed, supporting efficient operation and straightforward future expansion.
