1200 Watt Capacity

822PS Pump Sentry is among the most advanced sump pump battery backup system available. It 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.
