1 “Essential Appliances” are determined by the homeowner before installation and typically include lights, select appliances and devices. The energy storage system should not be relied upon as a power source for critical medical devices. The life of the energy storage system will vary depending on a number of factors, including, but not limited to: the amount of energy stored in the battery, the amount of wattage used by the appliances and electronics connected to the battery storage system, the age of the battery, the battery’s ability to recharge during daylight hours due to weather, the frequency and duration of battery usage, and other factors. Battery life will decrease with time and use.

SunVault™ Storage FAQs SunPower by Custom Energy
A home solar storage battery is charged during the day and can decrease the amount of electricity drawn from the grid at peak times or at night. It can also be used during an outage.*
SunVault? Storage is comprised of two boxes, the SunVault? Battery and Hub+? (the brains behind the system). Additionally, all customers receive access to SunPower's mobile app to view their performance and manage system settings.
Yes. SunPower provides a 10-year warranty for SunVault™ Storage as part of the Complete Confidence Warranty, the same warranty that covers your SunPower® solar system.
SunVault™ Storage is designed to charge when it is sunny and discharge when needed based on your settings. In your mobile app, you can select how much of the battery you want to use daily for savings and how much to reserve for an outage.
We recommend indoor installation, typically in a garage. Outdoor installations are possible in shaded areas and where temperatures remain between 15-110° F and are protected from other severe and extreme weather.
This depends on your energy use, utility rate, rate structure, and several other factors. Your SunPower Equinox® proposal will provide an estimate of your annual savings from your solar and storage system based on your current electricity use.

I had a SunPower system (35 panels and 2 batteries) installed by Custom Electrical (Custom Energy). I found them knowledgeable and easy to work with from the project start to finish. The design and install crews did excellent work and took my concerns into account. Their work was completed on time and on budget. I would use them again in the future and I certainly recommend them.— Steve Kaylor

We contacted Custom Energy late in the fall hoping that our system could be installed before year end. They worked quickly with the design and permitting process and installation was completed in December. They did a very professional job and everything works like it is supposed to.— ROBERT FOLEY
