Power Inverter to a truck battery (need help and ideas)
I bought a Roadpro RPPI-2500W 2000/5000 Watt DC to AC Power Inverter from Ama$on ($100 by the way) and would like to run a spot cooler of of it. Spot cooler is 690 watt 6 amps. My alternator is rated at 100 amps. Efficiency of an inverter is 87%. Do you think if truck will be running for 9-10 hours a day (FedEx truck) alternator will still be able to keep my batteries at above 50% state of charge so that they don't deteriorate?
I was calculating it like this: (690w/12v)/.87= 66.1 amp is required from my battery to run it.
so if an alternator rated to produce 100 amps it should be fine?
Your thoughts guys?
