The SAJ H2 & B2S is a flexible residential solar and battery storage solution combining SAJ's H2 hybrid inverter range with the modular B2S high-voltage LiFePO4 battery system.
Available in single-phase and three-phase configurations, the H2 range covers residential applications from 3kW through to 30kW, with fast battery charging and discharging, smart operating modes and backup switching in ≤10ms. Depending on the model, H2 inverters feature two or three MPPT trackers to provide greater flexibility when designing complex or multi-orientation PV arrays.
The B2S battery uses modular 6.4kWh LiFePO4 battery modules with a stackable, quick-connect design for straightforward installation and future expansion. Storage capacity can be configured from 12.8kWh up to 51.2kWh in a single tower depending on the H2 inverter configuration, with 100% depth of discharge and a rated cycle life of 6,000+ cycles.
