Modular Growth
System capacity scales by adding up to 8 battery modules, giving flexibility from small (10 kWh) to large (40 kWh+) installations. Installation is simplified by auto-recognition wiring harnesses.
Backup Power
When paired with SAJ’s backup-ready inverter, the SAJ battery supports seamless blackout protection. It can power essential loads automatically if the grid fails.
Integrated Monitoring
SAJ’s app and web portal allow homeowners to track their battery’s state-of-charge, health, and solar production in real time. Alerts and reports help manage usage for maximum savings.
Rugged & Safe
With IP65 rating, the SAJ battery can be installed outdoors. The high-quality LFP chemistry and built-in BMS (battery management system) ensure high safety and a long cycle life.
SAJ is backed by a global manufacturer with a track record in solar. They typically provide a 5-year warranty on their battery systems (with performance guarantees around 10 years). While not as widely reported as some other brands, SAJ batteries compete well on price and support. In Australia, they’re often chosen for their straightforward hybrid system integration and competitive cost.
