Thanks Brettski,
The system is built from "Outback" products and the inverter is true sine wave.
As for generator backup there is switching wired in such that we can manually switch over to generator power and have the generator feed both the electrical system to run the cabin and also the charger to charge the batteries. We would use the little 5000 watt gas generator that we have used for construction. We expect to rarely or never use generator power except for construction needs. The cabin is intended for only part time usage and the cabin's electrical load has been kept small - fans, lights, and computers for the most part. And I hope to teach my grandkids some energy conservation (course I never did do a very good job of getting my son Scott to turn off lights when he was young
