“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
“Six recessed lights in the kitchen and a dimmer that actually works. The ceiling patch was so small I didn't need a painter.”
“Sold our house and the buyer's inspector flagged eight electrical items. OSB fixed all of them in one visit and wrote it up so we could close on time.”
It depends on whether you want essential circuits or the whole house. A typical Onset single-family runs well on 18-24kW for whole-house coverage; essentials-only systems can be half that.
