The SunPower SunVault 13 is only compatible with SunPower brand solar panels

SunPower enjoys a well established reputation for high efficiency solar panels. In the second quarter of 2020, SunPower broke away from Maxeon to focus on distribution and sales, leaving all future manufacturing to Maxeon. If SunPower is indeed no longer involved with the manufacturing process, they are tight-lipped with details about the actual physical location or country that the Sunvault battery is manufactured.

The SunVault is a relatively new battery by SunPower. It is designed to work exclusively with SunPower solar panels. If it is important to you to have solar panel options, Sunvault may not be the best fit.

These batteries use a very safe Lithium Iron Phosphate chemistry and the Sunvault 13 model features a Total Capacity of 13kWh and a Usable Capacity 13.kWh.

SunPower Sunvault uses a Lithium Ferro Phosphate or LFP. In addition to increased efficiency, and extended life, this type of battery chemistry is thought to have a reduced risk of thermal runaway. The Sunvault has an average service life of approximately 10 years.

The Sunvault 13 can operate continuously at 6.4kW, with short bursts of peak power at 10kW.

Power Output

Continuous power is a measurement, expressed in kW, of a battery's potential to release a sustained energy for a given period. Peak power is a measurement, expressed in kW, of a potential maximum power output in short bursts. The SunPower SunVault 13 provides 10 kW of peak power and 6.8 kW of continuous power. The Sunvault 13 performs within the range of solar industry standards.

The Sunvault 13 has a roundtrip efficiency rating of 85% with 3% degradation.

Sunpower backs the Sunvault 13 with a 10 year or 4000 through cycle warranty, whichever comes first.
