Solar microgrid with energy management for a museum, Xiong'an, China

Microgrid · Public building · 21 kWp solar + 50 kWh battery + EMS · In operation

The project

A museum in Xiong'an New Area wanted a microgrid that could run on its own or alongside the grid, with little or no staff attention.

Component Specification
Solar PV 21 kWp
Inverters 4 × 5 kW
Battery 50 kWh LFP
Control Energy management system (EMS) coordinating solar, battery and grid
Output About 38,600 kWh per year, used on site, surplus stored

What it shows

  • Island or grid-tied. The microgrid runs on its own or alongside the grid, and switches automatically.
  • EMS control. One system balances solar, battery and grid, with real-time monitoring and alarms.
  • Hands-on commissioning. Our engineers surveyed the site and commissioned the system in person.
