Islandgrid / Microgrid function and Blackstart


All WSTECH Inverter´s for ESS application are available with optional islandgrid functionality. This function enables the inverters capability to act as the grid building device, the behaviour is partly very similar to a Diesel generator set. Several WSTECH Inverter units can operate in parallel in the operating mode Island grid.

The island grid function can be used for complete offgrid applications, without a public grid connection avilable or for example in region´s  with an instable public grid to supply critial loads during an outage of the public grid.

With a special function the WSTECH Inverter can operate as the grid building device, charging  the battery at the same time.

The black start function restoring a part of an electrical grid is given with the islandgrid option also, only the auxilliary supply must be provided externally, e.g. by an UPS
