Hi-PowerMaxx2 Battery Backup for Sump Pumps

Hi-PowerMaxx2 Battery Backup for Sump Pumps

Hi-PowerMaxx2 Battery Backup Power Solution for Uninterruptible Power Supply.

If the submersible pump loses mains power, the Delta Hi-PowerMaxx2
battery backup system kicks in and keeps the pump running. This
allows the sump pumps to continue to safely discharge water from a
basement even during a power cut. This battery backup is specifically
designed to run one or two Delta V4, V6 and Delta Bespoke V3 basement
pumps without mains power (not simultaneously). The Hi-PowerMaxx2
will automatically recharge when mains power returns.
