To solar or not to solar? That is the question....

We had good luck running unreliable power through battery charger (it does not pay a lot of attention to wildly varying voltage) and then running microwave or air conditioner via inverter as has been discussed elsewhere - one German couple burned out just about everything in Yucatan. We lost one micro-wavein Baja and another in Yucatan due to bad power and almost lost an ac unit at a state park in Colorado.
