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?
Cheers,
Dave
