Dual Tesla Powerwall Installation in King County

Most homeowners think one battery is enough. And sometimes it is. But when you want real backup capacity - enough to run your home through an extended outage or offset serious energy costs - two units changes the game completely.

This is a dual Tesla Powerwall setup we installed at a King County home. Two units mounted side by side on the exterior wall, clean and tight against the siding. The Powerwall is already one of the most capable home battery systems on the market. Stack two of them together and you're looking at double the storage capacity, which means longer runtime during outages and more flexibility with how you use and store energy from solar or the grid.

Here's what a lot of people don't realize about battery installs - placement and mounting matter just as much as the hardware itself. We position units to keep conduit runs efficient, protect the system from the elements, and make sure everything is accessible for future service. It's not just about getting the boxes on the wall.

We handle full Tesla energy installations, from single-unit setups to multi-Powerwall expansions like this one. Whether you're starting fresh or looking to add capacity to an existing system, we can walk you through what makes sense for your home and your energy goals.
