P1000 Posted May 31, 2023 Share Posted May 31, 2023 Those aren't 3 pole, they are just the higher voltage version. The voltage should match what your inverter can handle. If the arrestor voltage is higher than your inverter, it will only start working after it's too late... Energy-Jason 1 Quote Link to comment Share on other sites More sharing options...
