FoxESS EP12 Plus High Voltage Storage Battery 11.52 kWh LiFePO4
The FoxESS EP12 Plus is an 11.52 kWh high voltage storage battery with lithium iron phosphate (LiFePO4) cells, designed for residential and small commercial PV plants. It works at a nominal 384 V, with an operating range of 348–438 V: the high voltage reduces cable losses and improves charge and discharge efficiency, which stays above 95 % over the full cycle. The permitted depth of discharge is 90 %, equal to roughly 10.4 kWh of usable energy per module.
It is a modular system: up to 4 units can be connected in parallel to reach 46.08 kWh, so the storage can grow along with consumption. With an IP65 protection rating and a built-in heater it can be installed outdoors and keeps working down to -25 °C. Installation is floor or wall mounted, communication with the inverter is over CAN and five front LEDs show the system status. It is compatible with all FoxESS H1, KH, H3, H3 Smart, H3 Pro and US inverter series.
Key features
11.52 kWh at high voltageAn 11.52 kWh module at a nominal 384 V: lower cable losses and more efficient conversion than low voltage systems.
Expandable up to 46.08 kWhUp to 4 units can be paralleled, extending the storage over time without replacing the existing system.
Built-in heaterThe preheating function extends the operating range down to -25 °C, useful for outdoor or mountain installations.
LiFePO4 cellsLithium iron phosphate chemistry offers thermal stability, high safety and a long cycle life.
Flexible IP65 installationIP65 protection rating and floor or wall mounting, indoors or outdoors, with natural convection cooling.
Efficiency above 95 %Round-trip efficiency ≥ 95 % and 90 % depth of discharge, around 10.4 kWh available per module.
