Hi folks. Can someone help me make sense of what my system designer is telling me. They're saying I'm limited to a 3.8kW system due to the size of my mains disconnect at the meter. My house is laid out like this:
The thing that's clear to me is I'm limited to load side tap unless I want to dig through some trees. What's confusing is that, assuming my mains panel is 125A, I should have 25A to work based on the 120% rule. That's 6kW - not 3.8kW. Also, if I wanted to go higher, why can't I upgrade my mains panel? Also, why does adding a 125A breaker/disconnect to the existing panel change anything?
I'm in central Texas if that matters any.
- Meter is at the curb with a 125A breaker/disconnect
- Underground run to my house (some trees that will make digging a new run difficult)
- Mains panel in my garage (unknown size but at least 125A) - no additional disconnect
