I assume your primary inverter has a battery charger. You want your second inverter to have an internal transfer switch (so it will detect no shore power and switch to "invert" mode). But you do not want an inverter with a battery charger. Two battery chargers may not "play" well together. Xanterx Pro Series fills this requirement. Its available in 1000 and 1800 watt versions - 1000 watts is plenty for modern refrigerators. See: http://www.xantrex.c...-inverters.aspx ken
