I have the opposite problem.

I want to find a 100 amp, zero center. amp meter to monitor my overall
system..

My alternator and/or charer/invertor put out around 100 amps at the
beginning of a charge, while various tools and appliances draw as much as
10-15 amps each and can total, at times, 30-40 amps.

I don't have a sophisticated battery monitor system, but would like to
monitor the net gain or loss from the battery bank..

Right now I have a 100 amp meter that just drops below zero when the charge
is greater than the current being used. Not very accurate and may not be
good for the meter movement.

What you need to do is put a 100 Amp Shunt in series with the main
battery connection and then buy an appropriatly scaled Center Zero
Meter to connect to the shunt. Paul Hendricks at Hendricks Electric
at Fisherman's Terminal can set you up with this stuff.
