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.


* Your battery storage system’s ability to provide electricity to your home will vary based on a number of factors, including: the amount of energy stored in the battery, the amount of wattage used by appliances and electronics connected to the 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. The battery storage system should not be relied upon as a power source for critical medical devices. Battery life will decrease with time and use.

    Custom energy had repaired my solar panels, replacing all inverts and associated controls on Sun Power warranty. That is why I had Custom energy install my batteries for solar backup. They did a wonderful job, I trust them completely.

    They kept me informed through the whole process of installation. We had the roof replaced during the process, and the new roof looks amazing. The panels are working like they should so far(1 month), unless it snows then they work fine once the snow melts.

    We really liked the "all in one solar system" not components from different manufacturers. The system was expertly and timely installed. Both SunPower and Custom Electric meet all of our expectations.

    Custom Energy provided detailed, accurate and timely information. Our own research indicated that the manufacturer (SunPower) as well as Custom Energy provides quality products, good service and prompt response to any questions or issues. Our system was installed in a timely manner and is operating better than expected. I appreciate the all encompassing service approach - if I have a problem I call the same person regardless of the origin of the issue. I would not hesitate to recommend Custom Energy and SunPower to anyone looking for a quality system and install.

    Called for a bid and they were helpful and responsive. The layout appears to be able to satisfy our needs, but we were not able to move forward with the installation until later. Overall was good to get a bid and understanding of next steps.

    I purchased a 20kw system for $64.2k in 2021. I wanted the best panels from a manufacturer with the best reputation. SunPower’s panels and equipment met these requirements. Their Utah affiliate, Custom Energy, visited my home within the week of my inquiry and provided me with a clearly illustrated proposal which said my electric bill would go down from over $400 per month to $30 per month. I was skeptical of course. The installation occurred three months thereafter with little hassle and done with precision in one day. Other electricians visiting my home said the install was the “cleanest” they’ve seen. One year in and my monthly power bill is just $16…yes…$16. It’s amazing and I am very excited to no longer have a huge bill to run our air conditioning which can run very high in Moab, Utah’s desert where 100 degrees is typical. Love solar and love Custom Electric.

    The company was professional from start to finish. They had the product on hand, told me when the installation would start and when it would be finished. They provided weekly feed back telling me where the approval process stood and what I needed to do. After installation, they were there to answer questions about the system. When friends ask about my panels, I highly recommend SunPower by Custom Energy to them.

    The sales process was professional, easy to understand, and answered all our questions. The salesman was helpful throughout the whole process from placing the order to follow up after start-up. The company was also responsive in getting us documents necessary for filing for our tax rebate. The installation crew was quick and professional and did an excellent job. We only received about 2 days notice before their arrival. A little more notice would have been helpful. The new meter from our power company was installed a few days after installation was complete. When that was done the system was turned on. However, no power was being generated because of a communication problem. After calling Custom Electric they sent someone to rectify the problem within a day. Since then, the system has been operating well without any issues. The system size seems to have been determined well since it is generating enough power for our home usage and provides some excess which goes back into the grid. The app that reports how much energy the system is producing and how much the house is using is confusing and just wrong. This could definitely be improved since it has a lot of potential to give customers insight into their energy usage and production. Overall, I would highly recommend SunPower Equipment and Custom Electric to anyone who intends to add solar power to their house. The experience was positive and the people were helpful and responsive.
