So a carpenter was busy here at my house installing a new door in a steel frame. The door had to be turned around so he had to drill new holes in the frame.
While he was busy, my power just went off. No breakers tripped on either the main DB or the sub DB. However, my MPII just had its “Overload” light on. I had to switch it off, bypass it and switch it back on.
Then I received the emails from VRM "Overload L1 on VE.Bus.
Does anyone know what could have caused it? My grid was on at the time so my inverter couldn’t have been “overloaded”. There was also basically no loads on in the house at the time either.
Could this be due to a short on a circuit sitting behind the inverter? (Given that no breakers tripped)
