If I remember it was used to control the inputs of wind and gas powered generation units, when used in combination with solar.

I'll have to look into that too.
It's generally a good idea to only supply a subset of the outlets from your inverter unless you have a big honking battery bank. For example, if you wired it in to supply every outlet and forget to switch the refrigerator to gas-only operation, when the inverter supplies 120v to the outlet the refrigerator is plugged into, it'll dutifully switch over to 120v operation to "save propane" (while sucking your batteries dry.) Selective is good.

Keeping the microwave (if you have one) and the air conditioner off the inverter is good. Even if you have a big honkin' battery bank! Either one can drain your batteries stony dead in less time than it takes to say, "stony dead."

Hey I didn't even think of the fridge. I guess it wouldn't be prudent to have that or the A/C hooked up permanently on the AC circuit. I'll have to check the wiring out and see if there's an easy way to hard wire the inverter/charger to just the outlets desired, leaving out the A/C and the fridge outlet.

Thanks for the help figuring this out. Once I get the solar finished, I'll start tackling the convertor replacement, keeping your sage advice in mind.

Though I have an converter/charger (Intellicharger) and a small external inverter, I agree wholeheartedly with Lewster. If you can afford it, go with the Inverter/charger and definitely use a professional if you are not 100% sure you know what you are doing. Not only can a botched installation leave you in the dark, but can even be a fire hazard.
