Best Pure Sine Wave Inverter?

[fishsail18]

Ok so humor me here and help me with some math. All 115v a/c .
I have a Refer that draws 1.3 amps x 115v=150 watts is that correct?
then a freezer that draws .45amp. =52 watts and a part time small ice maker drawing 2 amps= 230 watts
total watts 432. and multiply by 4 for start up? = 1728 watts so theoretically a 2000 w inverter should work?
am I on track here?
Thanks very much

You should be ok with that.
Just remember that at full load even figuring 100% efficiency (more like 85%) your 12 volt current demand is going to be around 160 amps from the battery bank.



2000W = 158.73A
12.6V

It is highly unlikely they will all start at the same time, but your wiring must be ready for that load.
