EMS-ESS 5 kW Wall-Mounted ESS.

The single-phase entry hybrid: 5000 W of output with 21.7 A rated current, one to eight 5.12 kWh battery modules, and a 10 ms UPS-class switchover. Model codes LC-E2-510, LC-E2-515, LC-E2-520 and LC-E2-525.

5 kW · Single Phase

Whole-home backup in one wall unit.

The inverter, MPPT charge controller and LiFePO4 battery share a 600 × 420 × 600 mm enclosure. PV input is capped at 4000 W through an MPPT window of 64–130 V, and the system hands over to battery in 10 ms when the grid fails — fast enough that lights stay on and desktop computers keep running.

Gray Variant

Same 5 kW, in gray.

The gray 5 kW unit carries identical specifications to the white model — 5000 W output, 21.7 A, 10 ms switching and the same 5 + 10 year warranty. It is a finish option, not a different SKU family, so your stocking decision is purely about what your installers prefer on site.

Buyer Questions

5 kW, answered.

The PV input is capped at 4000 W across an MPPT voltage range of 64–130 V. Size the string so its open-circuit voltage stays inside that window and total input stays at or below 4000 W.

One to eight 5.12 kWh modules give 5.12 to 40.96 kWh of usable capacity. Each battery module measures 600/420/200 mm and weighs 54 kg; the base adds 600/420/130 mm and 17.5 kg.

The unit is CE/TUV certified with safety compliance to IEC 62109-1&-2, IEC 62477, MSDS EN 61000 and UN38.3, and operates over 170–280 V (UPS), 90–280 V (APL) and 183–253 V (VDE) grid ranges.
