Ok
So of you are asking about the load.
Well it would depend on whats running as fridge and freezer would be on 24/7. Then maybe once a day a washing machine load and tumble dryer load. Plus one computer in the day. During the evening it would be tv, lights and computer. I doubt that we would meet the peak load of what the generator can do. Yet if we had a battery packs installed etc they could be used first and we could kick in the gene if required.
Yes we do have the gene already at house.
With regarding the batteries we would take care of them to last and would be looking at the mid-range ones. This might sound a stupid question but how long would a battery last before it need charging kind of thing.
