The SAJ B2-12.8-HV1-S 12.8kWh Battery is a high-voltage energy storage solution designed to help households store and make better use of their solar energy. With a substantial 12.8kWh storage capacity, it can capture excess electricity generated during the day and make it available when solar production is lower, such as during the evening or at night.
Designed with modern residential energy storage requirements in mind, the SAJ B2-12.8-HV1-S combines efficient energy storage with a compact and practical design. Its intelligent battery management helps monitor operating conditions and supports safe and reliable battery performance. The system is well suited to solar-plus-storage installations where homeowners want to maximise self-consumption and improve overall energy management.
The battery provides a practical way to reduce wasted solar generation by storing surplus electricity rather than sending it back to the grid. It can also support greater energy independence by making stored energy available when required. Its high-voltage architecture and integration with compatible SAJ energy systems make it a suitable choice for a wide range of residential applications.
