I’m sure that somehow these are related but I’m so deep in diagnosing that I’m thinking I can’t see the forest from the trees.
I have a permanent surge protector and no factory generator.
First, I have been losing shore power intermittently the last few days. I was thinking the reason was I was running 2 a/c units on a 30 amp and the outside temp was very warm. When the shore power would drop out I would still have 12V in the trailer.
I moved today and am now hooked up to 50 amp service. Hot and humid so I cranked up the 3 a/c units. After about 30 minutes the shore power went out, the pedestal breaker was still ok. But when I lost shore power I also lost 12V. The control panel went dark. Then the power came back on and so did the control panel.
I have checked voltage across every breaker and i have battery voltage on both sides of the breakers. I also checked every fuse and those are all good.
Im thinking I have two issues. One is on the 12V side and the other is on the 120V side. Any input as to why I would be losing 12v would be appreciated. Maybe I’m just overthinking everything and am missing some easy.
now the batteries are not charging so I’m thinking once I figure that out I may be on my way to figuring out the 12V issue. The batteries still have 85% charge (I have a Victron monitor)
