About This Product

The SAJ B2S HV LFP 6.4kWh Battery Module is a high-voltage lithium iron phosphate battery module designed for SAJ B2S energy storage systems. Each module provides 6.4kWh of total and usable energy capacity and operates at a nominal voltage of 64V. The modular, stackable design allows multiple battery modules to be combined into a larger storage system, making it suitable for residential and small commercial solar storage applications using compatible SAJ H2 hybrid inverters.

Who This Product Suits

The SAJ B2S HV LFP 6.4kWh Battery Module suits customers building or expanding a compatible SAJ B2S high-voltage battery system. It is intended for installations using compatible SAJ H2 series hybrid inverters where modular battery capacity is required. SAJ specifies configurations of 2-6 battery modules with compatible single-phase H2 inverters and 3-8 modules with compatible three-phase H2 inverters, subject to the requirements of the particular inverter model.

Specifications Explained

The module uses LiFePO4 battery chemistry and provides 6.4kWh of total energy capacity with up to 100% depth of discharge under SAJ’s specified operating conditions. Nominal module voltage is 64V, with an operating voltage range of 56-72V and a rated/maximum charge and rated discharge current of 50A. The B2S platform uses a quick-connect stackable architecture, natural-convection cooling and an IP65-rated system enclosure when assembled as the specified battery system. SAJ specifies more than 6,000 battery cycles under its stated cell test conditions.

Summary

The SAJ B2S HV LFP 6.4kWh Battery Module is the 6.4kWh building block used within compatible SAJ B2S high-voltage battery systems. Its LiFePO4 chemistry, 64V nominal module voltage and modular stackable format allow installers to configure storage capacity around the requirements of the compatible SAJ H2 inverter and installation. It is a practical choice where a scalable SAJ battery solution is required for solar energy storage and backup applications.
