SolarEdge › grid/AC connection and site wiring
System backfeeds generator through transfer switch
manufacturer says
Symptoms
- With the utility out and a third-party generator running, the SolarEdge system pushes power into the generator, which has no reverse-current protection and is mechanically damaged (what SolarEdge's webinar calls rapid unplanned disassembly)
- The inverter also refuses to operate correctly on generator power because it sees frequency and sine-wave irregularities
