Fox ESS EP12 11.52kWh High-Voltage Battery with Heating

★ Ideal for

  • * New Fox ESS EP12 battery product page
  • * Homes needing 11.52kWh per EP module
  • * Higher-capacity residential storage systems
  • * Indoor or outdoor IP65 battery positions

⚡ Works well with

  • * Fox ESS H1, KH, H3, H3 Smart and H3 Pro systems
  • * Fox ESS HV Junction Box for parallel EP batteries
  • * CAN battery communication wiring
  • * Installer-selected battery isolation and protection

The Fox ESS EP12 supplier code EP 12 is an 11.52kWh high-voltage LFP battery listed by Fox ESS as model EP12 Plus, with 384V nominal voltage, 348-438V operating voltage and an IP65 enclosure. It suits residential battery systems where a higher-capacity EP module is preferred and where the installer has confirmed the compatible Fox ESS inverter and battery layout.

  • 11.52kWh nominal energy with 384V nominal voltage
  • 348-438V operating voltage with 30A maximum charge and discharge current
  • Floor or wall-mounted high-voltage LFP battery module
  • CAN communication with five-LED status display
  • Compatible PCS listed for H1, KH, H3, H3 Smart, H3 Pro and US series
  • 710mm wide x 640mm high x 185mm deep, 98kg, IP65
  • IEC62619, EN IEC 61000-6-1/2/3/4 and UN38.3 listed

Why choose EP12 over EP11-H?

EP12 provides 11.52kWh nominal energy per module, while EP11 provides 10.36kWh. The difference matters where the system design benefits from a larger module count step without changing to a different battery family.

The EP12 datasheet also lists a maximum of four units in parallel, giving a maximum stated EP12 storage capacity of 46.08kWh. Keep this new page separate from EP11-H so buyers can see the capacity and model difference clearly in the retained Fox ESS range.

How does EP12 scale storage?

Fox ESS lists EP12 scalability as a maximum of four units in parallel. Each unit provides 11.52kWh nominal energy, so the stated upper capacity is 46.08kWh.

Parallel EP battery systems require the correct accessories and must match the selected inverter configuration. The installer should confirm whether a Fox ESS junction box is needed before ordering the battery set.

What does the installer check first?

The first checks are inverter compatibility, battery count, mounting method and cable route. The EP12 datasheet lists compatible PCS series, but the final storage configuration still depends on the inverter model and current Fox ESS installation rules.

EP12 is rated for indoor or outdoor installation with IP65 protection. The wall or floor position must suit the 98kg unit weight, the required clearances and any service access stated in the latest manual.

Is EP12 a new product page?

Yes. The current LAMPS Fox ESS export did not contain an EP12 product page in the keep-list comparison, so this should be created as a new page rather than overwriting EP11-H or EP5-H.

What is the usable depth of discharge?

The EP12 datasheet lists 90% depth of discharge. Do not copy EQ4800 or EQ2900 depth-of-discharge data into this product, because the battery family and datasheets differ.

How many EP12 batteries can be paralleled?

The EP12 datasheet lists a maximum of four units in parallel. That gives a maximum stated capacity of 46.08kWh before inverter and accessory compatibility checks.

Does EP12 need a wall or floor installation?

The EP12 datasheet lists floor or wall mounting. The final method must account for the 98kg unit weight, substrate, clearances and the current Fox ESS installation manual.
