You can use a power inverter to power your sump pump during a power outage. Sump pumps vary in size. The most common that our customers call us to power are 1/3 horsepower sump pumps, and 1/2 horsepower sump pumps. The best option we have here at theinverterstore.com would be our inverter/charger with built in transfer switch.
From our experience, 1/3 hp sump pumps and below can be ran with our AIMS Power 1500 watt power inverter with charger and built-in transfer switch. For higher capacity pumps like a 1/2 hp sump pump you should use AIMS Power 3000 watt power inverter with charger and built-in transfer switch.
The sump pump is first connected to the power inverter. The inverter is connected to both your battery bank and city power. As an added benefit to this, the incoming AC power will charge and maintain the battery(s) for you. The sump pump is run off of AC power directly through the power inverter/charger. When AC power is lost the inverter will automatically transfer to the battery bank.
An automatic sump pump back up system, like the one offered by theinverterstore.com, gives the customer piece of mind. Back up sump pump systems ensure that the pump will have constant power supply whether you are home or away. As you already know hurricanes, tropical storms and other heavy rain can deliver a lot of water to your sump. Investing in an inverter/charger with transfer switch is better than repairing a basement from flood damage during a hurricane or heavy storm.
