Wall-mounted ESS, 3–12 kW.

A hybrid inverter and LiFePO4 battery in one wall-hung unit, sized from 3 kW to 12 kW across single and three-phase. The system mounts in about five minutes, switches to battery in 10 milliseconds, and scales from 5.12 to 46.08 kWh as your customer's load grows.

Why Wall-Mounted

Backup power without the battery room.

The whole system hangs on a wall like a flat-screen TV. Three color-coded cables plug into foolproof sockets, the ports are insulated to IP67, and the positive and negative terminals sit at 0 V until assembly — so installers and shippers stay safe.

  • 10 ms switchover (UPS, VDE) — lights stay on, computers keep working
  • 90–280 V wide input with constant-voltage output on unstable grids
  • IP67-insulated ports and foolproof sockets prevent reverse polarity
  • SOC breathing light: blue, green, yellow — red signals a fault
  • BMS monitors all 16 cells with 6 temperature probes
  • Universal wheels rated 150 kg for easy repositioning

Full Series

Nine models, three hardware families.

From the 3 kW entry unit to the 12 kW three-phase model, every system shares the 5.12 kWh battery module, TN grounding, 10-year design life and 5 + 10 year warranty.

EMS-ESS wall-mounted energy storage battery in white and gray factory color variants
Colors & OEM

White or gray, then make it yours.

Factory colors are pure white and gray, and both carry identical specifications. For distributors, OEM color matching, logo printing and private-label packaging are supported — the platform, certifications and APP monitoring stay unchanged.

Buyer Questions

Wall-mounted, answered.

Pick by peak load and PV size. The 5 kW takes up to 4000 W of PV with MPPT 64–130 V and suits most single-phase homes. The 10 kW accepts 13,000 W of PV with MPPT 125–500 V, outputs 10,000 VA at 43.5 A and runs at 98.2% efficiency — the better match for larger arrays and heavy evening loads.

Yes. Each 5.12 kWh battery module stacks under the inverter. The entry series (3/4/5 kW) takes 1–8 modules for 5.12–40.96 kWh; the high-power and three-phase units take 3–9 modules for up to 46.08 kWh depending on model.

Yes. White and gray are finish options only — power, efficiency, switching time, warranty and certifications are identical. Choose the color that matches the installation wall, or specify an OEM color at order stage.
