Backup Power in 3 Simple Steps
No rewiring. No plumbing changes. No complicated setup.
Plug It In
Stays on Standby
Automatic Backup
Plug-and-Play Setup
No electrician, plumbing work, or battery system modification required. Just plug your existing 115V–120V sump pump into PUMP PARTNER — helping avoid hundreds of dollars in typical backup pump installation or wiring costs.
Automatic Switchover
When utility power fails, PUMP PARTNER switches to battery output in milliseconds, so your primary sump pump can keep running without manual restart — especially important during overnight storms or when you are away from home.
Built for Sump Pumps
Designed for real sump pump behavior: long standby periods, sudden startup demand, repeated stop-and-start cycles, and high inrush current when the pump motor starts under heavy rain conditions.
2048Wh LiFePO₄ Battery & Protection
Built-in 51.2V 40Ah LiFePO₄ battery delivers up to 2048Wh of usable energy, with 4,000+ cycle life. Integrated overload protection helps respond to abnormal current draw from aging, blocked, or locked-rotor pumps.
