No the Gels haven’t stood up well but that’s not their fault . I knew bugger all about solar when we got the system installed and the installers were on a learning curve to it seems . DOD was not set up properly and nether were the charge parameters so we spent a whole summer not knowing that we were discharging the batteries way too much . Got that sorted then the system went at least 6-8 months in winter of only being charged by half the solar panels because the breaker to the other string had “broken” and I wasn’t keeping an eye on things . after all that I started keeping an eye on the system very closely but the damage was done I think . We have good quality outback brand kit all round so hopefully if we can get some good LifeP04 batteries it will be Plain sailing for at least 5 years hopefully more . I like the fact that lithiums are happy to be charged to any % and don’t need an absorb stage , that’s what is difficult in winter is getting the Gel batteries up to 90 odd percent then having a good few hours of sun on absorb to let the charge soak in . Ah ha, yeah they got off to a bad start, that's a bummer.
Also why I have all controls in the one spot including breakers. There is a master fuse out by the panels but if it pop there will be nothing coming in. All the rest I can see super easy and anything out of whack should stick out like bulls balls.
My solar guys and I have 3 sets all independent of each other and been in the game a long while, all reckon a good bank set up well should cruise it for many many years. They are all telling me the Gels should still be fine in 10 years as long as nothing goes bad in the system.
I will suss that mid winter 90% angle though as it is a important aspect. We should be fine as we have big panels in perfect sun (and hopefully on a tracker shortly) and having spend out lives on boats we have been trained in the ways of low consumption.
On Thursday I spoke to my Resource Consent specialist* about the legalities of having off grid in the Burbs. We're going to develop out city property into a pile of units and I'm sussing the viability of having them all off grid power wise. Also with water, putting in 2 separate systems, one to the kitchen and bath room taps with mains water, all the rest from tanks. If 3 Waters gets in water bills will sky rocket so build to minimise the need to be part of that shambles is the theory.
Now if they will only allow suburban long drops 
* - A handy man to speak to before everything else. He;'s already given us a 'Don't even bother', 'If you want to spend the extra' and a 'go for it' list to give to the architects.

Have a creek and are already onto that one. Also wind is in the mix but from what we're seeing in our solar system we're really beginning to wonder if we need any extra.
Just thinking if we can run an entire household with all it entails on a 14.4kw bank, some even smaller, and have shit loads of reserve then EV cars are pretty damn inefficient. A limp arse grade Nissan leaf needs a 14.4 bank just to get to bowls and back.
That would be heaps of storage for a “normal” house hold but not with a spa pool or heat pumps or electric oven ! just had a good look at wind and it’s not great for us , it’s great on boats or tiny homes but the big models cost shit loads and the output is lame for the $$ spent . I had two AirX marines on the motor home when I was building the house and they were great especially at night time in bad weather but that system was small . They both needed yaw bearings replaced after two years of chasing the breeze in circles …easy enough changing the bearings but taking the tower down wasn’t much fun and busted some blades which cost a bit to replace . Not a fan of spa pools, besides we already have a a pile of redneck spa pools, just stick a hose on the exhaust of the tractor and into a trough Never been a fan of pools but we'll have the 'water garden', the one that looks suspiciously like a small lake, to use in summer.
Solar water off the roof piped thru the slab for heating. We are talking 45 cubic of the stuff so once warmed up it'll take bugger ll to keep it up. Cooking off gas and a wood/scraps feed small pot belly like device that also has a wetback. While we're earning OK we want to put in as much redundancy and future proofing as we can.
We're doing a little work with a NZ start up that's developing a wind generator specifically for farms and small communities where getting mains is hard or to costly. Can't say much but it is a vertical system and the demo I saw was totally silent, freakily so almost when standing next to this good sized moving object. I have offered a corner for a trial one, if they want then I will but as time goes on the less likely it seems we'll need all that extra power.

That’s cool ! I’ve always been a bit annoyed at lack of vertical axis turbines here . They are quite common in the states and EU and make a lot of sense , especially if you have a dirty wind flow . Hope it goes well for them and will keep an eye out for them in the future

Hope it goes well for them and will keep an eye out for them in the future A place just down the road, a small block with a lifestyler heading towards hermit, gets all his power from 2 verticals and reckons it's all he needs. He brought them off Aliexpress about 5 years ago. He did say when he installed them he gave the exteriors another hell coat of paint, what was there made him a little nervous, not sure why, otherwise they have not been touched. He has them on a ridge so they get good wind.
I did consider following his lead but don't need the power at the moment.

I remember may years ago (like 40ish) there was a Darreius "hoop" type vertical axis turbine being run on a trial basis at a substation on SH1 heading north, maybe coming into Kaiwaka. One of the issues with many of the vertical axis turbines is they are not "self starting" Interesting paper here, don't be scared of the slides with maths, there are also pictures  www.wgtn.ac.nz/scps/research/attachments/turbinepres.pdf |

just consider this if you are thinking about buying an EV, comment from a blog
Okay, listen up. Further to Shaw's latest drivel about his wonderful new scheme re EVs, take this on board. Over in the UK, they are somewhat further ahead than New Zealand with the introduction of EVs, and as of 30 June 2022, the Electric Vehicles (Smart Charge Points) Regulations come into force. All home installed EV charges will be required to be separately metered and be able to send information to the Smart meter data communications network. (like your hot water does now) Potentially this legislation allows the electricity used for charging EVs to be charged at a higher rate than domestic electricity. The technology enacted also enables the rationing of electricity for EV charging because the government can decide when and if an EV can be charged, plus it also allows the EV battery to be drained into the grid if required! If enacted here, EV owners will be required to have installed in the garage where they intend to park said EV, a separate charging point, separately connected to your meter board, accessible to the power company to turn it on and off at will, and then drain that overnight charge you thought you were putting in your EV’s battery! Given the nonsense we are already being subjected with the Covid mandates and such like, will you really want to be party to this sort of control by this government, and / or your power company? So, the salient points are, that if the current shower go the UK way, which is highly likely, once they have everyone in an EV, THEY will decide how and when you may charge it, charge you whatever excessive amount they want, and having paid an exorbitant amount to charge the damned thing, can drain your battery for the national grid!

Mr Fish sweetie, I suspect that while the post is inflating the negative a similar suggestion was put forward by Mr Shaw I'm thinking about 2 years back. I'm 90% sure he did suggest EV's could 'become part of the national grid when parked up'. That would require a separate connection for your EV. Also add into the mix a how a suggestion like that sold by the powercos to the pollies would go down in Welly. The powerco can control supply for the good of the nations supply but for a small premium they would ensure you'd get all the charge you needed and the pollies could say 'No cars on Tuesday due to blaa blaa blaa'. A little out there or would have been a few years ago but today that is a real possibility. I wouldn't twaddlebollocks too prematurely. Now a question. Do you miss the days of being able to drive at the speed limit. Judging on the EV's I follow so often the chances are I'll be shagging Princess Kate long before a EV will get a speeding ticket. Why are they all so bloody slow or is it a case the drivers see their life as being finished so have just given up and brought a EV while they wait for the big clocking off   |

Turns out this is actually a result of the bean counters at work, they have found that it is cheaper to put in a bigger electric motor with no gearbox than to fit a smaller electric motor with a gearbox. I would think the latter would be more efficient due to less current draw particularly on acceleration. I think the slow cruising speed is due to a combination of worry about running out of kW's and an EV being about as exciting to drive as opening your fridge door  |

While you are bagging KW anxiety go bin the solar system on your boat and install a generator …biff out your battery tools too ! It’s all green shit for kaftan wearers 😂 |

Why are they all so bloody slow or is it a case the drivers see their life as being finished so have just given up and brought a EV while they wait for the big clocking off Are you serious? My PHEV appears to have a slight problem with speed camera's.... AND, why do you think NZTA re dropping the speed limits around the country to 80 or even 60 on State Highways? They say it is for safety, but really, it is so EV drivers can hit the speed limit............ The Twaddlebollocks part of CZ's post, was, well, fairly much all of it. When we were doing watermain replacement in London, we were installing supply meters as we went. We had the exact same reaction. Mainly that the govt were going to use said mechanical water meter to spy on people, and listen to their thoughts. Not long after that the comms team banned me from talking to customers... (apparently I lacked tact and discretion when responding to these questions - true story.) Trying to use a conspiracy theory in the UK to not buy an EV in NZ? More to the point, Shaw announced a plethora of twaddlebollocks new rules and "initiatives" yesterday (or the day before). You could drive a bus through almost all of the logic of that stuff - like subbsidies so that poor families can buy a Tesla... most of them just want a warm dry house and 3 cans of baked beans a day... On the technical element though, do you think Shaw understands that getting 100v DC out of a car with a battery management system, into a National grid at 240 V ac, via a standard car charger may be problematic? This is the same party that thought di-hydrogen-oxide was a thing and wanted it regulated. If everyone has an EV, then it would be logical for powerco's to implement some demand management capability, same as when hot water cylinders first came out. Doesn't mean everyone ditched their hot water cylinders and went back to wet-backs & Argas though did it? |

Hey Fish, as you are well aware we are seeing governments wanting to control our lives like never before (look what happened in Canada recently with the Freedom Convoy supporters) and when you consider concerns being raised about future Digital ID's, Programmeable Central Bank Digital Currencies and a Social Credits system it is entirely possible to face the scenario of governments applying controls as envisaged in the quote I posted. As far as Vehicle to Grid drawing on EV's batteries, this capability is already been included in some vehicles and it may finish up all EV's are required to have this. Currently (no pun intended) from www.elektrobit.com/trends/vehicle-to-grid-technology/: As of 2021 there are only a few commercially available cars that are V2G compatible:
Nissan e-NV200
Nissan LEAF
Mitsubishi Outlander PHEV
Mitsubishi Eclipse Cross PHEV
From 2022 on all electric vehicles from Volkswagen that use the MEB (modular electric-drive toolkit) will be V2G capable Look, even the later version of your trusty Outlander PHEV

Yes, but you presented those issues as a reason not to get an EV. Or at least that is how I took it, this being a thread about EV's and all. The issue of govt controlling our lives is different to the pro's and con's of getting an EV. There was once upon a time that the govt controlled the supply of petrol, and you couldn't drive on certain days. The most obvious solution would be to not connect your EV to the grid. GO30 and em are already fully off grid, and it probably makes good economic sense to just use solar to charge anyway. The issue will be around cloudy days of course. But I think it is hopeless to discuss the merits of EV's bases on future govt control. There are much more pressing issues with EV's. The obvious two are range and environmental impact of making the batteries. I'm far more interested in hydrogen as a long term solution. Just need to understand how to make it. PS, does anyone actually understand the Carbon Budget Shaw put out earlier in the week? If you already have an emmissions trading scheme, and petrol co's are paying for the carbon in petrol, why do you need to fuck around with all this other complexity and bureaucracy? AND, if you are taxing the carbon in petrol, isn't it good when petrol gets expensive? So isn't then dropping the petrol tax counter-productive? Or is the main issue the economy getting completely screwed over and inflation going nuts, what with petrol forming a key cost for every household and every consumer good? |

Taking a longer horizon - the world is pouring mega bucks like you can’t imagine into building:
1. New battery building capacity
2. New battery tech
The expectation is that this will ultimately lead to:
1. Geo-independence so major govts & alliances have their own secure supply of batteries (source materials) breaking the near 100% dependence on China that we have today. In other words the world is turning battery producing into the oil-producing equivalent of the next few decades. We all know how oil dominates geo-politics and so there is huge motivation to achieve a reset as we move away from oil to electric.
2. Usability. The battery nerds are predicting that in the foreseeable future you will buy a battery pack and it will outlast the car itself. You’ll keep the battery pack for years and swap out the rest of the car when the body & parts become tired. If this seems far-fetched look at how other tech has advanced over the years when markets are motivated to find new solutions.
