SunPower doubles SunVault Storage capacity to 26 kWh

SunPower has increased the storage capacity of its SunVault Storage batterynow providing whole-home backup capability.

SunVault now offers double the energy as previous iterations with 26-kWh and 52-kWh configurations. The first version of the battery, released in 2019, reached 13 kWh.

“As power disruptions are becoming more commonplace, the demand for energy resilience and reliability is higher than ever,” said Nate Coleman, chief products officer at SunPower. “With the new SunVault, we are going beyond just the essentials. Customers can have the peace of mind that even if their grid service is disrupted, their lives don’t have to be.”

The lithium-iron phosphate (LFP) battery comes with a 10-year warranty, including 70% usable energy retention. This warranty update raises the standard for residential energy storage systems with no restriction on total energy throughput or the number of times customers can charge their battery.

Customers with SunPower solar systems can also take advantage of the company’s Complete Confidence Warranty, which covers everything from panels and racking to monitoring hardware.

The new SunVault storage system is available now with installations set to begin in June 2022.
