Yes you can. You can get dual use inverters that can then be used for both panels & batteries. Otherwise you need 2 inverters as I found out. Normally the batteries won't feed the house at a power cut but you can get a normal socket fitted off them. I think we were quoted c £250 for that.

Surely it costs the environment the same, no matter what time it's generated? Nope. Consider the difference between nukes and gas for example. A nuke has to run at more or less full bore all the time, whereas gas can be turned up and down at a moment's notice. One of the tradeoffs is therefore environmental impact vs flexibility. Historically it has been well-nigh impossible to store electricity so we've been constrained to only using nukes to provide baseload. Now we have batteries we can decrease the amount we need to use gas by shifting night generation to use it in the day. And about the 50% efficiency in 20 years who cares I'll be dead thing....if my current system was working at 50% I (and maybe most of us) woukd find that unusable so would either have to use the grid more (which will have been the case all through as the efficiency decreases) or replace the batteries. Assuming replacement, hasn't that just handed a huge problem to the next but one generation.
Batteries aren't exhausted in the same way that fuel is though, they just need to be recycled Don't both the above scupper the eco argument and expose the true motives for all this...financial gain?
It's certainly true that a lot of people are only prepared to shift to low-impact energy usage if it's of financial benefit to them, which is pretty depressing really, but I suppose it's better than refusing to do anything. Are you telling me only nucleur runs at night, no gas? No eco cost in recycling batteries? Don't forget they have to be replaced by the initial owner , so new ones for every recycled. But people aren't refusing to do anything.nthey can't afford it.mA proper way forward wouod be to subsidise it in a way that allowed ordinary people to take eco steps rather that a simple financial gain for already wealthy people. Remember that all these subsidies are financed from extra charges added to the bills of the folk who can't afford to take advantage of the offers.

No but ditto night storage etc etc. By the way the panels produce DC so if you have batteries at the same time you only convert it once to AC in the same way you do with PV energy directly. But I was clear in my statement that I was only talking about charging from the grid not about directly from panels

My system has also saved 18 tons of co2 in just over 4 years. I've no idea if that compensates for the co2 to build it but makes me feel good. That's a really good point I think

Nick .... errmm yes! ... me 🙂
That's because I'm off-grid in the strictest sense .... no 'eco-power' ... no power at all
In the same way I think every driver should spend time on a motorbike before they get their car licence to sharpen their road-awareness .. I think everyone should spend a couple of years really off-grid (or with a smart-meter that simulates that and can't be bypassed) ... to learn the strengths and weaknesses of renewables and fully appreciate living within your energy means.
K Nice one. I know three people off grid entirely. The only thing is they all need a very large amount of land to support them. So it's unsustainable in that there isn't enough land to support the population that way. These people I know still need diesel etc. So they have to have income. So they're only off grid in a relative sense. They still need the benefits of ordinary organised society. One has 200 acres, one 75 and one 5. Hard to defend on an ecological argument.

I hope you don't mind me going on about this. I'd really like to think it's a way forward and I'm hoping to learn from replies that it is. But it just seems to me we need a whole rethink of the financial side of it to get anywhere. I'm almost getting lefty in my old age....

I do like off-grid as a concept.
I guess I was kinda operating off-grid as a spotty yoof, and for much of my adult life in regard to minimal purchasing power to buy any new m/cycle or car, which forced me to acquire the knowledge to return old machines to usage over many years. I have never purchased a new motorcycle, and bought my very first new car circa a decade back, when in my late 60`s..!
Along the lines of that which K typed, whatever restriction causes you to operate "off-grid" in the wider sense, would also seem to have the potential to alter one`s perspective on much by some considerable degree...?
Hoping to pick up a new Tesla in a bit over a week, I don`t need to be spitting out diesel fumes performing mundane motoring tasks, and given our minimal mileage these days, the Tesla seems to have potential to fit in reasonably well.. Time will tell. I would like to go the whole hog and install solar panels etc. etc, but as ever "disposable income" limitations play a part, though If in time I end up selling my planet killers in the form of my C4S and +8...Hmm..?

Nick ... the amount of land required is only unsustainable if you don't consider reducing the population to the levels where the land will support them sustainably ... I have no kids as a deliberate choice (if they start energy allocation then anyone with no kids should get considerable leeway as their choice has saved the planet from a cascading avalanche of future consumers down the generations 🙂) .... it's impossible to live without environmental impact ... however we can aim to reduce it to below the levels where the environment passes its capacity to heal itself ..... we're way beyond that currently and with no prospect of reaching it while we adhere to an obviously catastrophic 'continuous growth' philosophy. Best we can do is manage the little bit we have control of the best we can and trust to being buried before the broader societal consequences come home to roost. K

I too enjoy the perspectives ... the Mog community is both intellectual AND alternative (hopefully these are not related!). I've always been disappointed by the building / heating industry in that - given the generally agreed climate crisis - things like heat batteries are still unheard of in new builds (which generally still go up with 0 PV panels, or in some cases a token 4 - with little concern about South facing roofs...). Amazing.
