Answering Your Questions About SunVault


How does SunVault work?

SunVault works by storing excess solar energy during the day in a lithium-ion battery. Then, in the evening or during outages, it uses that stored energy to power your home, reducing reliance on the grid and potentially lowering electricity bills.

Why should I choose a SunVault battery system?

Consider SunVault if you want to maximize self-reliance on solar power and reduce electricity bills. It stores excess solar energy for use at night or during outages, and SunPower offers a long warranty with no limit on charging cycles.

How much does SunVault cost? 

The exact cost of SunVault depends on your system size and local market. SunPower offers financing options, so you can spread out the cost.  Federal tax credits are currently available for solar energy systems, including battery storage.  Consult with SunPower by Sun Solar for the latest pricing and incentive information.

Will SunVault work with my existing solar panels?

SunVault may potentially work with your existing solar panels, but with a caveat. It depends on the inverter you have. SunPower SunVault is designed for AC coupling, meaning it connects on the alternating current side of the inverter.

Here's the key point:

  • Compatible: If your existing system uses a compatible AC inverter, SunVault can likely be integrated.
  • Not Compatible: If your system uses a DC (direct current) only inverter, SunVault likely won't work and inverter replacement might be needed.

It's best to consult with SunPower by Sun Solar to assess your specific system and confirm compatibility.


What are the space requirements for installation?

SunVault doesn't require a massive space, but it's not tiny either. A single unit (13 kWh or 19.5 kWh) is comparable to a large refrigerator. For more storage (26 kWh or 39 kWh), a double unit is needed, doubling the space requirement. We can help you determine your exact space needs based on your chosen configuration.

How long can SunVault power my home during an outage?

The exact duration SunVault powers your home depends on how much energy you use and the battery's capacity. A fully charged SunVault system can power your home for several hours, but factors like appliance usage significantly impact runtime.  It's important to work with SunPower by Sun Solar to accurately assess your energy consumption so you can purchase and install the right SunVault system size.

What is the lifespan of the SunVault battery?

SunPower offers a 10-year warranty on the SunVault battery, guaranteeing its performance for a decade. However, the lifespan can potentially exceed 10 years depending on usage patterns. Like most lithium-ion batteries, SunVault batteries are designed to maintain at least 70% capacity after ten years.

Does the SunVault require any maintenance?

SunVault requires minimal maintenance. Unlike lead-acid batteries, SunVault's lithium-ion technology doesn't require electrolyte level checks or replacements. The system itself manages battery health and performance. You'll mainly focus on keeping the surrounding area clear and well-ventilated for optimal operation.
