Deye SUN-STS500L 500kW static transfer switch, grid generator loads
This is the panel that decides where the power comes from: grid, generator or battery. It handles 500kW on all three sides, transfers in 10ms or less and already contains the 250A breaker for the PCS AC cable, the metering circuits for grid, loads and generator, the generator start contacts and two digital inputs. One module serves a 500kW PCS or four 125kW units, and up to five modules work in parallel for 2.5MW. We supply it with the industrial storage kits that include it, not as a stand-alone part.
