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?
