Subject: Re: lv-ab: Sizing marine air and inverter?
One of the major problems with this setup is the startup current
required by the compressor. I tied this once with a 2600 (1800
continuous) heart inverter and a 6000 btu reverse air. It would not
start the unit but would run the unit. I started it with generator
power and ran it off the inverter. Next problem was after it satisfied
the demand it would shut down and would not restart.
Not a real practical method of cooling. Try a small box fan and a quick
shower. Works wonders.

Time to get updated on the available technology!
I just visited IBEX and paid particular atttention to the issue of air
conditioning and inverters.
Mermaid of Fort Meyers has been especially diligent in developing low
power, high efficiency compressors for use with inverters.
In addition, they adopted one of my suggestions and added a time delay to
their control box for a really soft start that greatly reduces start up
surge.
I currently have two prototype installations running on some government
vessels where the inverters are driving a heat pump HVAC unit for both
cooling and heating onboard. So far the sea trials are sucessful.
However, the trial period will not be completed for three more months
because one of the test boats blew an engine.
Can't test the system when the boat is laid up getting a new engine
installed.
While it may not have been practical with yesteryears technology, it is with
today's models and several manufacturers already have product off the
shelf.
