I have an install that has had a few problems with its inverter. It burned out a communications card inside the inverter and now it appears to have done so again. The install is 16 270W modules in one string with a Solaredge SE5000 inverter. We are in Guatemala so there are no NEC rules and no inspections. The distribution panels (2) are home made with breakers mounted on DIN rail and a bus bar for ground and another bus bar for neutral. It is also a very high lightening area. The house has had one direct hit that cracked a cement wall. I was down there troubleshooting the inverter and decided to look closely at the house wiring. I could not find where the ground was connected to neutral. I checked both panels - nothing. I followed the ground wire a bit, but could find nothing. As part of the normal inverter inspection I had found 0V ground to neutral.
If there is no bond between ground and neutral, what would go wrong under normal use? or when lightening hits?
