Overview
Equinox Storage is SunPower's new product line for residential energy storage. It contains SunVault battery system and Hub+. SunVault battery system integrates inverter and battery pack along with an enclosure with built-in forced convection cooling system. On the other hand Hub+ is the brain of Equinox storage that can take form of a main service panel.
Design and development of Equinox Storage involved defining system architecture, layout, and allowable loads, component loads, design, analysis and testing, manufacturing, system installation and field support.
