OTDC disconnect switches
Disconnect switches can be used in three different levels of an Energy Storage System (ESS): battery racks, combiners and Power Conversion Systems (PCS). The most suitable switch to use depends on the size of the ESS, and whether the topology is behind or in front of the meter. Utility scale ESS (>1 MW) have "front of the meter" topology.
