The TruCharge 40+ has no provision to limit the input current - don't
know about the ProSine.

Peter, the manual says:

"The ProSine 2.0 uses a Power Share feature which senses the AC load
on the system and gives priority to your AC loads, thereby reducing
the charger current ... Sometimes the usual AC shorepower sources have
a low voltage. To avoid loading these weak sources any further, the
charger automatically reduces its AC current draw as the AC voltage
approaches the minimum acceptable level (as set by the user)."

Sounds great in theory, and the ability to set the triggering AC
voltage level will give some ability to tune the system. But as Wayne
says, there might be a surging effect - especially if the generator is
running when the air conditioner compressor goes on.

That's why I'm looking for people who have tried this sort of thing.
It's a bit hard to breadboard up a system without making a major
investment in at least some of the components.
