Fox EQ4800-L9 HV, 41.93kWh 1x Master 8x Slave

The EQ4800-L9 is the largest configuration of Fox ESS's EQ4800 high-voltage battery, pairing one EQ4800-M master module with eight EQ4800-S slave modules in series for 41.93kWh of nominal storage. Each module adds to the stack via a plug-and-play connection, so the system scales without rewiring the master unit. Built from LFP cells with CAN communication back to the inverter, the stack is rated for 90% depth of discharge and a round-trip efficiency above 95%. It is designed for outdoor or indoor installation and suits larger residential or light-commercial systems needing high-voltage storage from a single compact footprint.
