So, say I've got a measley 2 group 27s and my old Yanmar 2GM15 and I
want to by a 2300watt continuous inverter. BUT...

I'm willing to run the Yanmar while I'm using any heavy loads like a
power tool, microwave, or electric heat and I only use the inverter
*without* running the Yanmar/alternator for small loads like a TV/VCR or
a boombox.

Any problem with that?

If I recall correctly, the stock (Hitachi?) alternator on my 2GM was
only rated at 35 amps - that would only be enough to sustain a 3 amp
(360 watt) load at 120 volts. (I replaced the stock alternator with a
higher output unit, and a smart regulator, to give me some chance of
keeping the batteries charged.)


There are two alternators shipped with the small Yanmars - a 35 Amp
and a 50 (or is it 55?) Amp Hitachi. I have the larger. On one
engine I replaced it with a Balmar, but on those times that I've had
to use the Hitachi for primary charging I've been disappointed in its
output. I don't think it ever got to 35 Amps, and this was only when
there was a heavy load.
