Fox EQ4800, 4.66kWh HV Battery (Slave)

The EQ4800-S is the slave module of Fox ESS's EQ4800 high-voltage battery range, adding 4.66kWh of LFP storage to an EQ4800-M master unit. Up to eight slave modules can be stacked in series behind a single master, taking the system to a maximum of 41.93kWh. Each slave connects via plug-and-play cabling with no separate BMS of its own, drawing power management from the master module. The stack is rated for 90% depth of discharge with a round-trip efficiency above 95%, suited to residential and light-commercial installations that need to add high-voltage capacity incrementally.
