Batteries - Why do my batteries go dead so fast?

Why do my batteries go dead when I use the inverter/charger in invert mode?

A Schneider Electric inverter takes available battery power and converts it to AC power to operate household appliances. In many cases there are additional "hidden loads" that will draw power from the inverter even when they are turned off. Some examples are: TV tubes being kept warm and microwave & VCR clocks. In addition to AC loads, there may also be DC loads that draw power from the same battery bank as the inverter. These loads can include CO detectors, accent lighting, and water pumps. Phantom loads may consume over 70 amp hours per day and most banks will be depleted in about three days with the inverter running with no loads on connected.
