Storage
Backup that earns its keep.
Whole-home or essential-load backup, solar self-consumption, and resilience—installed by a Tesla Certified Installer.
Tesla Certified Installer
One partner.Every volt.
Solar on the roof. Powerwall on the wall. A car charging in the carport—managed by Tesla Home. DES installs that stack as a Tesla Certified Installer, and still owns the industrial power work behind plants and campuses.
A whole-home Tesla energy system: Solar Roof, Powerwall storage, and Wall Connector charging. DES is a Tesla Certified Installer of these products.

From Wall Connector to fleet.
Tesla Wall Connector for homes, plus commercial and fleet charging with capacity planning and commissioning.
Tesla Home
The operating system that comes with every Powerwall.
Tesla Home is Tesla’s home energy management system. It ships standard with every Powerwall and is powered by Opticaster, Tesla’s AI optimization software. DES installs and commissions the hardware so Tesla Home can run—we did not build Tesla Home or Opticaster.
Tesla Home comes standard in every Powerwall. When DES commissions your system, the Tesla app is part of closeout—not a separate product sale.
Where Tesla and the local utility offer a program, Powerwall owners can participate in Virtual Power Plant events in Tesla Home. The app can prepare for a grid event—charging the battery to support the grid and maximize payout—and you can opt out from Home Status. DES installs the system that enables this. Tesla operates Tesla Home, Opticaster, and VPP.
Set your goal
In the Tesla app, prioritize savings or solar self-consumption. Set Backup Reserve so a slice of the battery stays ready for outages.
Maximize savings
Opticaster analyzes household usage, solar production, and utility prices, then times charging and discharge around that goal.
Monitor your system
See the day as it unfolds—solar, battery, home load, grid, and the car. Change preferences anytime without a truck roll.
