I would go even larger than that. with a 28' run I would not go any smaller
than #0. Inverters do not like low voltage and #2 will drop the voltage
almost half a volt at normal draw and can handle a maximum of 178 amps which
is to small to handle the 200 amp peak. #4 is fine for 100 watts over a
total of 10' (out and back) but not for 28'. For the 10' run (20' total) to
my Prosine 2.0 Xantrex recommended 450mcm. I scrimped and used #0000 and
will just have to be careful about getting over 2kW.

I have a 1200 watt nominal / 2400 watt peak, power inverter that I
would like to install about 12 feet from the battery that will power
it. My question is what gage wire will I need for a 14 foot run to the
inverter? The unit was supplied with 5 feet of 4 gage. Is 4 gage
really necessary, it seems like overkill to me? Thanks, Mike Howard

I'd use #2.
