Paul Z. Posted July 8, 2021 Share Posted July 8, 2021 Odd thing just happened to me. I fired up my new PJ 8kW inverter to run the entire home (ran just fine for about 5 mins) but as soon as the solar came online, the PJ mos boards exploded. The solar system consists of 12 grid-tie micro inverters, which should have synced up to the PJ once the rapid shutdown delay was over (5 mins). The solar system is 5 kW, and I'm sure that the loads were less. Shouldn't the balance backfeed through the transformer into the battery? Or would this cause the inverter to fail? I also had an autotransformer connected elsewhere in the system, because the micro inverters are 240v only... but I doubt that had anything to do with the failure.
