This unit will run off the new Honda eu1000i 1,000 watt portable generator, while in cool mode.  Another option is to use a Statpower 1,800 watt inverter and 450 amp hours of battery power and you can anchor out (one average) for one night.  We have actually had success operating the Mermaid Model M5 off as low as a 1000 Watt Inverter and only 400 amp hours of battery power, however, longer operating times, it is recommended to use a higher wattage inverter and a bit more battery power.

Due to the construction of this unit, electric heat is not an option with this unit.  This unit is ideal for the “tight fit” installations and is a welcomed addition to larger vessels for individual climate controlled cabins.  The Mermaid Model “M5” has a rotatable blower so, no Air Discharge option is necessary.

On average, this unit is designed to cool cruisers up to 26′ and sailboats up to 28′.
