Re: Choosing a good generator
First a question. Why would you need more than you can get from a 2kw inv genset? That's what I'd go for if my 10kw diesel died completely on me.
Natural gas...you can't store it, if supply is interrupted you're somthing out of luck. As you said, Gasoline it is.
What about a larger inv genset, Honda goes up to 5kw for your shop loads and charging.
Presently the freshly charged lithium starter battery measures 12.32 volts after removal from a cold car environ. Turning it on along with the built in small flashlight lowered the voltage reading to 12.28 volts. Pretty disappointing. Warming it up to room temperature to see what voltage will read.The 12.32V reading would indicate an almost completely discharged 4 cell lithium ion battery, fully charged would be in the mid 13V range.

Living in the lightning capital of the US, I never understood the concept of grounding the PV frames, that's a couple hundred square feet of lightning attraction that at best will vaporize the ground wire and at worst cause your home to burn to the ground.
PV cells don't touch the frame, the Jbox or MC box doesn't touch the frame, there is no way a panel defect can energize the frame.
One of the nice things about regulations, is that is ALWAYS up to the local inspectors to what is acceptable, regardless of what the NEC has written.
In all my installations, with full written approval of the local inspectors my frames are left un-bonded to anything. the last thing I want is to be waving a flag at the next bolt of lightning to say HIT ME HERE and that is exactly what grounding the frames do.
Each and every year I get about 20-30 hits within a few hundred feet of my home. Last year the street light got nailed and took out 2 inverters by backfeeding in the mains. That street light is less than 30 ft from the solar panels .. so I think its safe to say my preference saved my array/house from a direct hit!
I'm not sure how John Wiles became an expert in lighting issues and best practices of wiring to write regulations for the NEC, but where he lives I doubt he see the activity in his lifetime I see in one rainy season here in central Florida.
