Tripp Lite APS750 inverter/charger 750 watt.
Wire: 6 guage up to 10 feet (per tripp lite tech support)
DC Fuse: 150 amp. (still have to order this).
I did a test with a standing fan and it ran for over 6 hours and only brought the battery down to the 80% to 90% charge range. nice.buickanddeere wrote:If the inverter input is 12V and the output is 1200W. Current on the 12V input side will be 110-115amps. #6 wire is going to get hot and a 40amp fuse is going to go poof.
I was thinking of another post with the 1200W numbers. 750W on 12V is going to draw approx 85amps at full load. #6 is ok on short runs as voltage drop will be limited. The wires will get warm particularly if they are together or in confined area with limited airflow. Ideally 85amps needs #4 or #3 .
