How do I keep my 1/3 horsepower sump pump running during a hurricane or tropical storm?
You can use a power inverter to make sure your sump pump keeps working during a power outage. We recommend the AIMS Power 1500 watt power inverter/charger with built in transfer switch. Along with the inverter, you will need a battery bank to power the sump pump when the AC power is out.

The size of your battery bank will depend on how much emergency backup power you want to provide your sump pump system. We recommend that you use deep cycle batteries, which you can find on our site. Generally, 1 or 2 AGM sealed lead acid 100 amp hour batteries would be the minimum battery bank you would want to install. Keep in mind that a couple of extra batteries could save your home from major damage during a storm, so do not be afraid to have more power than you think you need. You will be much more comfortable in a hurricane or storm knowing you have this extra power on standby.

The inverter will need to be connected to the battery bank using #4 AWG UL listed cables. recommends always using an inline fuse kit within 12 inches of the battery bank on the positive terminal. A fuse kit prevents a battery fire caused by a ground fault. When the AC power goes out, this inverter/charger will automatically switch over to run off the batteries. Eliminating the need to wake up in the middle of the night and start your noisy generator.
