SAJ is a global energy technology manufacturer specialising in solar inverters and battery storage systems. Founded in 2005, the company has established a strong footprint in Australia, delivering reliable and cost-effective energy storage solutions for both residential and commercial applications.
The SAJ B2 Series is a modular lithium battery system designed to deliver flexible and scalable energy storage. Built using LiFePO₄ (Lithium Iron Phosphate) chemistry, the B2 series prioritises safety, long service life, and consistent performance.
Each battery module provides 5.12 kWh of storage, with systems expandable up to 25.6 kWh, making it suitable for a wide range of energy demands. The robust IP65-rated enclosure allows for outdoor installation, with options for wall-mounted or floor-mounted setups. Advanced features such as remote monitoring, firmware updates, and CAN communication ensure seamless system integration and ongoing performance optimisation.
The SAJ HS2 Series integrates a hybrid solar inverter with modular battery storage into a single, streamlined unit. This all-in-one design simplifies installation and improves overall system efficiency.
The HS2 range is available in both single-phase and three-phase configurations, accommodating different household and commercial power requirements.
Single-phase systems support up to 18 kWh of usable storage
Three-phase systems extend capacity up to 22.5 kWh
These systems are engineered to maximise solar self-consumption while maintaining high conversion efficiency and reliable backup performance.
SAJ energy storage solutions are positioned within the value-driven segment of the Australian market. They offer an affordable entry point into battery storage without compromising essential features or safety standards. Customers should consider performance expectations, warranty coverage, and local after-sales support when selecting a system.
