100-Amp to 200-Amp Panel Upgrade to Power an EV Charger

A 100-amp panel used to be plenty for most homes. But that was before EV chargers, heat pumps, and whole-home backup systems became common. Once you start adding that kind of load, a 100-amp service just doesn't cut it anymore - and pushing it too hard creates real problems.

This homeowner was ready to add an EV charger and wanted to make sure their electrical system could handle it. The old meter panel came off the wall - you can see the rust and age on the removed unit - and we put in a fresh 200-amp service. Clean install, properly sized for what's coming next.

Going from 100 to 200 amps doubles the available capacity. That's not just enough for an EV charger. It's enough headroom for whatever else gets added down the road - a hot tub, a home addition, a backup battery system. The upgrade essentially future-proofs the electrical side of the house.

This is exactly the kind of work we do before the charger goes in, not after. Getting the service right first means the charger install goes smoothly and everything downstream is on solid footing. No shortcuts, no workarounds.

If your home is still running on a 100-amp panel and you're thinking about an EV or any other major addition, this is the conversation to have early. A panel upgrade is one of those things that's a lot easier to plan for than to react to.
