Hi All, I will soon be installing one of these in a detached shed, where it would be useful to have a light installed. There will be no panel in there other than the GridBOSS, inverters and batteries. The manual says that the smallest breaker size that is supported is a 30a breaker. See table below.
I emailed their tech support to ask if there would be a problem with a 20a breaker. They gave a very basic answer pointing me back to this same table, and then recommended to add a subpanel, and then run a 20A circuit from there. That seems a bit overkill for a light. I cannot see why if a 30A breaker is allowed, a 20A breaker would not be allowed. It is just a simple Eaton breaker. Am I missing something here?
