Indeed. After I replace the fuse, I'll have to be watching for fault currents while I start it up. Unfortunately the encapsulation makes "snooping" pretty difficult without extensive excavation and dismantling - all likely to do more harm than good. This microinverter is already scrap, and I am trying to fix it just so that I can have a working spare on hand. For when the next inverter fails. Which is inevitable, it seems. If my tinkering fails, not a big loss. I just have to proceed carefully. |

Looks like Jeroen3 and Xena are right. Something else is wrong with this unit. I replaced the fuse, but when I attempted to power it up, it gave no sign of life. I'll keep searching for another problem. |
