A sump pump control system for monitoring and driving AC pumps that are supplied by directly either by AC utility power, or converted DC battery power. AC power is continuously monitored and the control automatically switches to DC battery supply in the case of power failure. DC battery power is converted to AC power. The control is equipped with unique pump switching circuitry allowing the pumps to be configured in parallel or staggered positions. Both pumps automatically alternate to prevent damage to pumps from humidity and corrosion that can result from remaining idle. Each pump has its own float switch to control operation. A third float switch controls both pumps in case of failure of either pump or float switch. Multiple visual and audio signals are included, displaying present power and pump conditions as well as alerting to any pump malfunction. The control utilizes two 12 volt deep cycle lead acid batteries that are being monitored for voltage level and continuously trickle charged to maintain maximum capacity. Batteries can be paralleled to obtain longer pump running time when AC power fails. The control system also allows for use of a single pump in the absence of a second pump.

A programmed microcontroller based sump pump system includes multiple pumps that can be employed with one as a primary pump and one as a back-up, or can be employed in combination to increase the discharge rate.
