Here's How Pump Sentry Works Battery Back Up For Sump Pumps 1200 Watt Capacity 822PS Pump Sentry interfaces between a pump and its AC wall outlet. When AC utility power is present, the 822PS charges a battery and monitors the wall outlet to detect a power outage. At the moment utility power fails, the 822PS draws energy from a battery and converts it to enable pump operation. When utility power returns, the 822PS automatically switches the pump back to AC wall outlet power. At the same time, the 822PS resumes charging the battery to return it to full capacity in preparation for the next power failure. Pump Sentry interfaces between a pump and the AC electrical supply. When electricity is available, Pump Sentry charges a battery and monitors the power line to detect a power outage. At the instant that power failure occurs, Pump Sentry draws the energy stored in the battery and converts it to AC power. This AC power is automatically channeled to the pump to maintain its operation in the absence of electricity. When AC utility power is restored, the Pump Sentry reinstates AC utility power as the prime energy source to operate the pump. Simultaneously and automatically Pump Sentry commences the recharging of the battery, to return it to full capacity in preparation for the next power failure. Designed to operate most 1/3 Hp sump pumps.
