Battery Storage

Store Energy For When It Matters

Sunergy Systems is a proud Seattle based Tesla Powerwall Certified Installer and SunPower SunVault Elite Dealer. We offer a customized solar-plus-battery solution that enables you to access the free, abundant power of the sun when you need it the most, for back-up power in the event of a grid outage.

Even In An Outage, You Won’t Feel Powerless

Our energy storage systems are specifically designed to provide you and your family peace of mind in the event of a power outage. Its unique power detection system will sense outages in real-time and automatically switch over to battery power! During power outages, solar shuts down in homes equipped with solar electric systems alone. However, an energy storage system keeps the solar activated, and depending on the weather, can extend the storage capacity during prolonged outages for many days!
