OP: Let me put a shameless plug in for having a little Honda EU2000i as a backup for your solar system. Caca Happens. When it's been three days without sun, and the XYL wants to blow-dry her hair, you'll be a hero. Greatest little things since sliced bread. Toss a gallon of gas at it and it'll run 12 hours charging batteries. Very quiet. And perfectly happy running out of gas, so you don't need to baby-sit it. Plug. Pull. Go away. Come back to a full charge and firm ice cream.
Yamaha makes a very good inverter genny too, but my fav is the Honda. YMMV.
You're in signals? Extra class ham here. PM me if you want to yak on 40 meters some time.
BTW: your ham ticket gets you some amazing pricing (and free shipping) on an EU2000i from Mayberrys.com. Call 'em and introduce yourself.
