Panasonic, which makes batteries for Tesla, is one of the top producers of batteries in the world. It introduced its residential battery storage device, the EverVolt, in 2019. The EverVolt is a scalable energy storage system that’s configurable as an AC or DC-coupled system.
The Panasonic EverVolt system is designed to work as a DC battery when connected directly to a solar array. With a Panasonic EverVolt SmartBox, it can also take power from an AC solar array. The SmartBox is Panasonic’s intelligent load management system, which transfers power from the grid to the battery during outages and can manage power to devices in your home during a blackout. It can also maximize your energy use to maximize potential savings by using your power when grid prices are high and pulling from the grid when prices are low.
The Panasonic EverVolt Battery is available in 3 different cabinet sizes and 9 kWh, 13.5 kWh, and 18 kWh options. They’re modular and you can combine up to four units together achieving up to 72 kWhs of storage capacity for whole-home power for days of energy storage.
Panasonic’s battery and home energy system carries a 12 year warranty. The warranties cover the batteries. Panasonic also offers a 12-year warranty on other EverVolt home energy system products including the hybrid inverter and SmartBox systems.
