Read our privacy policyProtect your home from rising sump water with the iON 55ACi+, a 1/2 HP sump pump system designed to provide dependable primary pumping and emergency backup protection. With up to 65 GPM at 10 feet of total dynamic head, the system uses standard 120V AC power during normal operation and automatically switches to auxiliary AC power from two connected 12V AGM batteries during a power outage.
The 55ACi+ includes the iON+ Switch with integrated high-water alarm, an 800 VA power inverter/charger, and a non-corrosive battery enclosure. Its solid-state level control, audible and visual alerts, and automatic battery charging provide added protection against power outages and rising water levels.
The iON 55ACi+ combines everyday sump pumping with automatic emergency backup in one system. During normal conditions, the 1/2 HP stainless steel and cast iron pump operates from standard 120V AC utility power. When utility power is unavailable, the system automatically switches to auxiliary AC power generated from the connected battery backup system.
This dual-source configuration allows the same high-capacity pump to continue removing water during a power outage without requiring a separate conventional DC backup pump. The 55ACi+ can also be used as a dedicated secondary pump alongside another primary sump pump.
With up to 65 GPM at 10 feet of total dynamic head, the 55ACi+ provides strong water-removal performance for residential sump applications. Its auxiliary AC backup system allows the pump to maintain its high-capacity operation during a power outage.
During normal operation, the system uses household AC power rather than stored battery energy, helping preserve battery capacity for emergency conditions.
The 55ACi+ includes the iON+ Switch, a solid-state level-control system designed to operate without moving parts or contact points. This provides automatic pump control while reducing the mechanical components commonly found in traditional float switches.
The integrated high-water alarm provides both visual and audible notification when elevated water levels are detected, helping users respond to potential flooding conditions.
The included 800 VA power inverter/charger converts stored 12V DC battery power into 120V AC power when utility power is lost. This allows the 55ACi+ pump to continue operating during a power outage while maintaining its high-capacity AC pumping performance.
The system requires two 12-volt deep-cycle AGM batteries, which are sold separately. When utility power returns, the inverter/charger automatically resumes charging the batteries and keeps them ready for future emergency operation.
The iON 55ACi+ includes a 1/2 HP stainless steel and cast iron sump pump, iON+ digital level control with high-water alarm, 800 VA power inverter/charger, and non-corrosive battery enclosure. Two 12-volt deep-cycle AGM batteries are required and must be purchased separately.
The system can be installed as a primary sump pump with automatic battery backup or as a dedicated secondary pump alongside another primary pump, providing flexibility for residential sump installations.
Proper system selection depends on required flow rate, vertical lift, discharge piping, fittings, total dynamic head, basin dimensions, battery capacity, and installation conditions. The 55ACi+ provides up to 65 GPM at 10 feet of total dynamic head, while actual flow varies according to total system head and discharge configuration.
An 18-inch diameter by 24-inch deep minimum basin is recommended. The system requires two 12-volt deep-cycle AGM batteries for backup operation. Always verify basin dimensions, discharge piping, electrical supply, battery specifications, pump configuration, control settings, and applicable local codes before installation.
The iON 55ACi+ includes a 3-year warranty. For proper installation and dependable long-term performance, verify the required basin dimensions, discharge piping, electrical supply, battery type and capacity, pump configuration, control settings, and applicable local codes before installation. Refer to the manufacturer's operation manual and installation documentation for complete installation, operation, maintenance, and safety requirements.
The iON 55ACi+ is a 1/2 HP battery backup AC sump pump system designed to provide dependable water removal during everyday operation and continued pumping capability during power outages. Rated at 65 GPM at 10 feet of head, the system uses household AC power during normal operation and automatically switches to battery-powered AC backup when utility power is unavailable.
Built with durable stainless steel and cast iron construction, the 55ACi+ is designed for reliable residential sump applications. The system includes a high-capacity pump, automatic power inverter and battery charger, battery enclosure, and iON+ solid-state level control with a high water alarm. Two 12V deep-cycle AGM batteries are required and sold separately.
