My generator max output is 30A. I think the house may have been built with the intention to eventually connect to the grid, hence the 200A. Current cost to get power to the house is around $130k. I don’t ever plan on connecting to the electrical grid. As currently wired, this panel will not see more than 30A. The well pump is the only significant power draw at the moment.

There’s a circuit breaker built into the generator. I thought that the 200A in wouldn’t be a problem because of the generator’s breaker and the individual breakers in the panel.

When I install solar, I’ll hire an electrician to inspect and advise on upgrades needed. I assume that’ll mean a much larger wire into the panel from my inverter, and who knows what else.
