Re: Perfomance data from LiFePO4 (LFP) Battery
Thanks for the information, he is another Australian, lives on the opposite side of the continent. Looks like he installed his LFP battery in December 2012 about four months before I installed mine. Impressive that he has been off-grid since 1991.

If you went to the outback tech forum and pm gorden Lunbaunm.

Re: Choosing a good generator
My belief is the best generator is no generator other than the solar system. Let ol' Sol do the warming and when it gets cold, move to a warmer location. Only fuel used is the gas to get you to a warmer location. I haven't one single clue why people want to live where it's cold. Masochists, I suppose.
What about a solar system? Gensets are for Tyrannosaurus Rex and its relatives.Ralph Day said: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.

Re: Lithium "jump start" batteries are worthless when it is cold.
As another Colorado resident, I think I will just say that there are lots of reasons to live somewhere other than the places that people flock just for warm weather. I think I'll stay here and know that @OldMan won't be. Sounds like we both will be better for it.

When they lost the personal ads (one of their revenue streams) they might have had to loosen up elsewhere to offset the loss of the predators, hookers and lost souls.

Re: Panel Angles
wayne,
wow, you must be half asleep as if you look to the upper right of his post it says baton rouge la and that's in the south so no snow belt there. hurricane belt maybe.
thomas,
it may be possible to tweak it, but from your results, if it ain't broke why fix it?

Re: NEC 2017 and RSS - I feel so blessed
Some regions simply require code for even off grid homes.
One was really funny require was posted here years ago, Their inspectors even required a utility meter socket for a solar powered off grid home (confused some people seeing an empty meter socket and they had AC power at the cabin).

Re: Lithium "jump start" batteries are worthless when it is cold.
There is no option for AC charging, only from the cars 12V cigarette lighter. That is just one flaw.mcgivor said:softdown said: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.
Oh yea, this is the net. Where everybody knows much more than me. About everything.

Re: Limiting Flow on AC voltage - Grundfos 11 SQF 2 pump
You are right about old school not always being the best school. lol Looked at the pump curve.
Looks like you need a variable DC power supply to dial your pump in to your needs when running off a genny.

Solar Guppy wrote: »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.
