SAJ HS3-3K-S2-W-PX All-in-one Hybrid

SAJ HS3 Single-Phase All-in-One – The smart, all-in-one solution for your energy management

The SAJ HS3 Single Phase All-in-One has been specially developed for modern residential buildings and combines all the key components of an energy storage system in a single unit. The hybrid inverter, battery storage, battery management system (BMS), energy management system (EMS) and provision for a 7 kW electric vehicle charging module work together seamlessly to enable the efficient use of self-generated solar energy.

The HS3 series is available in power ratings from 3 to 6 kW and features two independent maximum power point trackers (MPPT), allowing even complex roof orientations to be utilised optimally. With a maximum PV input power of up to 12 kWp and an input current of 20 A per MPPT, the system is ideally suited to modern high-performance solar modules.

The integrated LiFePO₄ battery storage system operates within a voltage range of 380 to 500 V and can be flexibly expanded to accommodate up to eight battery modules. The battery modules are connected via an intelligent plug-and-play system without the need for additional cabling, making installation and subsequent expansions particularly straightforward.

With a maximum efficiency of 97.6 per cent and a European efficiency of 97.2 per cent, the HS3 operates particularly efficiently. Comprehensive protection functions, such as reverse polarity protection, short-circuit, overcurrent and overvoltage protection (AC and DC), AFCI arc fault detection and integrated off-grid protection, ensure safe operation.

Communication is conveniently handled via Wi-Fi, Ethernet or, optionally, 4G. The SAJ app allows you to clearly monitor energy generation, storage status and consumption at any time.

Thanks to its compact design with a depth of just 170 mm, IP65 protection rating, natural convection cooling and an operating noise level of less than 35 dB(A), the HS3 is suitable for both indoor and outdoor installation. An integrated self-heating system and a fire protection system within the battery ensure reliable operation even at low outdoor temperatures.
