Gents you both have me lost for words.
I heart forums for that. Idea propagation and considered responses.
CM. The green issue. Haha...I see green fallacy more often than fidelity. We both like empirical data.
I cannot claim to be green, I do not. My carbon footprint is that of a Godzilla. They paid me to do it (I hold my hand up to say that does not make it right either). I can use 200kAh at work in 4 hours for a societal memory and no more but contaminated soil and waste to dispose of. I know buildings the test load is 1000A per phase.
Off-grid power versus grid-tied; Grid-tied is greener. No throttling, community benefit, considerably less hardware.
Off-grid lifestyle versus grid-tied; Off-grid is greener. I lived for 10 years on 20L of water a week, 500Wh and not wanting. And yes they were diesel hybrid Wh.
Off-grid infrastructure; not financially competitive.
Off-grid under-the-radar agricultural land-living, capable, critical thinkers not willing to invest 20 years of their life to a mortgage to play by the rulez. Ha well...standards are your own but I would say it's cutting out a lottov of middlemen who may or may not be justified in their positions. While not profitable is substantially more affordable.
What I acknowledge is off-gridders like reliability and proveabilty. The cost is not as significant as these.
Grid-tied users generally want a financial return on investment to entertain the merits of conscience, misplaced or otherwise.
Damon, I remain unconvinced to the comparative appropriateness of privately owned dynamically operating grid-tied batteries. They are to me entirely of benefit only to situationally dependant economic factors of marginal merit compared to say insulation, usage reduction, intelligent load triggering. They are certainly not greener than batteryless systems that have no round-trip efficiency losses. It seems often an exercise in proprietary electron farming with a higher embedded system loss than more traditional use it or lose it installations where the network benefits more and is sure to offset dirty fuel instead of heating hybrid inverter transistors. They are pretty far down the curve of diminishing returns long beyond low-hanging fruit.
I am running a grid-tied battery and the jury's out. The two unprovable factors are; Is the LFP projected data accurate (be a cynic until proven otherwise) and can LFP perform better than lead (is that the same question)?
I've invested €8k of hardware and a 18-month build in the experiment. I am a sceptic I will overthrow diesel-electric as a consolation
price prize.
I think a 10 year payback is too long regardless of ethics.
4 years. 10 hires...that's business. That ain't green either.
In any case, I'll be hibernating it for November to March because solar excess won't be a concern and operating temperatures are. I could dynamically grid-tie a lead battery but I already know the answer to that one and lead's waaaay cheaper.
I had a thought bubble the other yesterday. Would people charge their E-bikes by riding an exercise bike if time wasn't a factor? I don't know the answer.
Time or money?
I don't know too many dyed-in-the-wool off-gridders who invest in new hardware. Most buy it tired, worn out, discarded, untested and put it right. ..muddy waters..hrmm..
I can't help much to put it into effective writing either.
I'm sure somebody else has though...
The question is in many aspects similar to what is the true weight of art? What is music worth?
I often undermine my own reservations. Is 400kAh an appropriate cost for world-changing inspiration?
