The team behind EMS-ESS.

EMS-ESS designs, engineers and services micro-grid energy storage for homes and small commercial sites. We pair 3–12 kW hybrid power with 5.12–30.72 kWh of LiFePO4 storage plus GTB grid-tie microinverters, and sell through distribution channels in more than 20 countries.

What we do

Micro-grid storage, from R&D to after-sales.

EMS-ESS is a high-tech enterprise focused on the research, development, design, manufacturing and service of micro-grid energy storage systems. We deliver integrated photovoltaic-plus-storage solutions: a hybrid inverter draws energy from PV, grid or diesel, and stacks LiFePO4 modules from 5.12 kWh up to 30.72 kWh behind it.

Our tagline is “Energize the world.” In practice that means millisecond-class changeover — 10 ms on UPS and VDE modes, 20 ms on APL — a 90–280 V wide-voltage input that keeps output constant, and a 0 V transport-safe port design.

  • 3–12 kW power and 5.12–30.72 kWh usable capacity
  • Multi-source input from photovoltaic, grid and diesel
  • GTB grid-tie microinverters from 400 to 1600 W
  • One certificate pack: CE, IEC 62109 and UN38.3
Milestones

A decade of storage, in five markers.

2016
Founded in Changsha
The engineering team behind the storage platform is established as a micro-grid energy storage company at the Lugu Science & Technology Industrial Park in Changsha, Hunan.
2019
Hunan Leading Innovative Enterprise
Recognized in March 2019 as a Leading Innovative Enterprise of Hunan Province, together with an 800,000 RMB provincial innovation reward. The low-voltage LC-E1 prototype followed in May.
2021
MUSE Design Award — Gold
The residential storage line won Gold in the product design category at the MUSE Design Awards (June 2021), confirming the industrial design of the wall-mounted and stackable systems.
2022
CE & grid-connection approvals, plus iF
CE certification and grid-connection approvals for several countries were obtained in June 2022, the iF Design Award followed the same year, and in April the team was named a Hunan High-Tech Enterprise.
2022–now
European service & global distribution
The European after-sales service center was established in Hungary in October 2022, and distribution channels now span Hungary, Sweden, Czech Republic, Iraq, Poland, Nigeria, Bangladesh and the Philippines, among more than 20 countries.

Our principles

Four commitments behind every unit.

Safe storage

10 ms switchover keeps lights on and computers running; built-in automatic fire suppression and a 0 V battery port protect installers and shippers from the first touch.

Multi-source input

Every system accepts photovoltaic, grid and diesel input simultaneously, with 90–280 V wide-voltage input converted to constant output.

Modular expansion

Start at 5.12 kWh and stack up to five modules as load grows, reaching 25.6 kWh without replacing the inverter or rewiring the site.

Intelligent O&M

The APP plus EMS cloud platform monitors all 16 cells and 6 temperature probes, with remote fault diagnosis and SOC breathing-light alerts.
