Dingbatt:

The house would need to be isolated from the grid while being powered by the generator.

I would not do the following because I wouldn't trust it, but as a matter of curiosity, what would be the catch in just turning off the mains switch at the fuse box, thus isolating the house, then making a power cord with two plugs and connecting the generator to any house circuit, using that to feed the rest? Of course you would have to be careful not to overload the generator, but even then the safety would just break the connection. What is it actually that makes this a very stupid idea? I'm sure there must be something I haven't thought of.

Noob here - what does an inverter do? I.e. how might that be a better option than a non-inverter model?

With a non-inverter generator you're getting whatever the generator happens to throw out, fine for running a concrete mixer before the site has power but a lot of electronics really, really doesn't like being run from that. The inverter takes whatever the generator is putting out and converts it to a steady 230V 50Hz with, for the better ones, a reasonably clean sinewave.

The big hazard is stuffing up the process in a panic and livening up the street because you did it in the wrong order. Also no idea if the mains is back on.

Someone might see the switch is off and turn it back on thinking it would make something disconnected work again.

Someone unplugs the cable and fries themselves on the end of it because they have no idea what it is for or the risks inherent with it being there.

Same thing but cable tripped over because its not put in a way to prevent that.

Not very well isolated inverter output blows up at having one of its output pins connected to earth by the MEN link in the board connecting them.

Cable being found later by someone who thinks its an extension cord and only finds out after plugging it in when they grab what should be the socket and and find its live.

There are different kinds of power. Some devices, like heaters, aren't too fussy. Others, like computers, TVs, and almost anything expensive and electronic, will have an instant stroke if they don't get the high quality stuff.

Handle9: They followed the rules presented to them.

You can get basically nothing out of the forestry industry and put everyone involved out of work or you can get nothing out of the forestry industry.

Up to you.

Again that is BS. So by your claim nothing should done to industries that are killing people and or causing immense damage to infrastructure land and waterways. hmm now lets think are there industries that have been required to change?

Auto industry required to change design and compulsory installation of safety equipment, EG Seat beats, design of front end to protect pedestrians

Building industry, banning of asbestos, earthquake mitigation.

All industries, emmission controls.

Toy and infant equipment, must meet strict child safety regulations.

Drug Industry, must meet strict safety regulations.

Shall we go on. How many of those industries are still going strongly? Why should the forestry industry be exempt from this scrutiny, legal requirement and responsibility regarding environmental damage and human life? What gives the forestry some kind of right to destroy large swathes of countryside and waterways, destroys homes and businesses and take lives.

I agree things need to change. That wasn’t what you originally posted.

You want the forestry industry to pay for fixing the damage from the flooding. There is no practical way to make that happen.

Solar probably not suitable due to us living in the Waitakere Ranges :) Thanks though!

Unless you're incredibly shaded it's actually surprisingly viable, the friend of mine that I mentioned in that thread is in Swanson, with tall trees on three sides of the house. For that batteries help, they soak up the sun during the times the house isn't shaded.

But don’t grid tied Solar systems need some sort of extra wizardry to operate during a power outage? Which is what I think the caffynz is after?

Inverter one has the alternator output turned into high voltage DC where it is then chopped up into a sinewave with basically a big class-D amplifier outputting what should be a good sinewave.

They do not like loads that have massive inrushes and will do protection from that which may blow up other devices connected to it, whereas a non inverter generator will bog down and slowly come back up to voltage and frequency as it catches up with the load, but then when you disconnect the big load will overshoot the voltage as the voltage regulators on those are somewhat primitive.

You basically decide if you blow up your electronics when you start the circular saw on the inverter one, or when you stop it on the non inverter one.

For most home loads outside of primitive motors you don't really matter which you get if you are not going to try running big things at the same time. Inverter ones dont need the engine to run at a constant speed so will idle down as needed saving a crapload of fuel.

neb: "hey, I listen to 1ZB and I'm only 76 you insensitive clod!", I'm just using all the talkback listeners I know of as case studies.

Lol, yes, Im not 76 but its the squeaky wheel. Mark Richardson is a classic example. its not about the content its about me getting my share of clicks.

Listening to talkback radio (and those muppets in particular) is much like listening to a couple of drunk people at a bar that are 'experts' on everything....

Ive only had x minutes of exposure this week so i will make more happen...

I have been thinking about a similar thing. Despite not losing power in the recent events, I am thinking a generator may be a good idea.

We are in the process of getting our distribution board replaced in the house to allow for EV charging and the installation of solar. I’m thinking I will ask how much it would be to provision for a generator.

It would need to be for essential equipment in the house, preferably on 1 circuit.

The house would need to be isolated from the grid while being powered by the generator.

A petrol generator would need to operate in a ventilated, but secure space.

Hopefully I wouldn’t need to charge the EV using a petrol generator 😉

But your many previous posts are very anti climate change so why bother??? Its not like it will happen that often, unless a Tonga underground volcano appears again???

I took a long breath before composing this to stay within the FUGs.

But here goes…

Because, unlike your quasi-religious adherence to the climate apocalypse, I’m all about mitigation instead of meaningless sacrifice*. I’m not sorry for pointing out some facts that may have contributed in this latest terrible weather event. But I have less faith in our already stretched electricity grid, as it is expected to do more and more but is still vulnerable. Add to that, the likelihood of electricity costs trebling and my planning may be a bit clearer. Produce some of my own and have a backup.

I assume you’ve actually bothered to look at the IPCC’s AR6 after being called out on it? Some of your posts would appear to show you haven’t. And how can someone be “anti climate change”? It would be more accurate to say Anti Climate Change Extremism. At least you didn’t use the “denier” label because what can’t be denied is that the climate changes (always has, always will) and that humankind affects the environment we live in.

* Even if you reduce NZ’s 0.17% contribution to GHGs to zero while simultaneously crippling our primary income earners, it will make no difference.

Look in the mirror. If you feel that CC is fake news, just say so. All I mentioned is that you are anti CC as evidenced by your many previous posts, its not an attack at all, so dont make it up

your quasi-religious adherence to the climate apocalypse

I assume thats not an attack.... What it is, is that you decree you are correct and I am the others are wrong

I am aware of your facts, and also acknowledged them. You seem to avoid the blatant trend post Industrial Revolution.

climate changes (always has, always will)

Old news, yes it has and it will, but not as much as it has in the last 200 or so years. Life adapts, but in life cycle issues, thats hundreds of thousands of years and longer, not 200. We can all list the many changes that have occurs on Earth. They take a LONG time, life adapts. Not when its a blink in time, as 200+ years is or 1000 years is

If you wish to debate it dont blow it off as a personal attack. Just tell us and the scientists that the last 200+years is fine and that Hawkes Bay is the fault of the Tonga undersea volcano. In which case, nothing to see here, its all good and unlucky. I dont subscribe to that

Thats the fail. CC doesn't care about boundaries. The Earth is 8 billion people, who cares who is Kiwi or not?

Yup, and that's covered in the solar thread.

That's probably the best capsule summary of talkback radio I've seen, with the one modifier that they're cranky drunks not happy drunks.
