Hi.
I presume that most of You use a lot of auto cbs, 10A or 13A for 230 Volts AC and DC CBs for the solar side.
However, I have removed the 13A CBthat was placed after my 230 V ACinverter.
MostInverters areprotected against shorts and other mishaps, so a CBon the AC side should not be necessary, butthe CBs makes it possible to disconnect some of the load if needed.
Yesterday I wantedto install a newly bought ACmeter and switched off the AC breaker.
When finished, I turned the CBback on: The result wasa loud bang and a light flash inside the CB. The CB simply exploded :huh:
The explosion obviously caused a huge electricalspike and this destroyed my Inverter.
Now I am going to replace the CBs with plain switches. I will leave the protection to the inverters.
Just to let You know.
