The Vulcan Well Pump Backup Unit is a rugged, autonomous battery system designed to keep your well pump running when the grid goes down. It supports 240V pump motors up to 1.25 HP with a simple two-step installation—no transfer switch, sub-panel, or tie-in switch required. Just wire it between the pump breakers in your electrical panel and the pressure switch, and you're set for seamless, uninterrupted water access during power outages.
