Back-feeding a dead grid is indeed deadly and very illegal! Every single domestic level Grid-tie inverter has island-protection built-in to prevent just that situation from occurring. Grid goes down, inverter shuts down. Exporting energy to a live grid is a different situation altogether. The inverter generates slightly greater voltage than the grid and energy flows to the grid.

Since they likely use more than 300 units in total it won't make any difference to their costs. If you use less then 300 units you won't get any advantage either ????

There's finally been an announcement, of course no actual detail other than it covers January to April 2023.

It looks like they are continuing the reduced FT rate that was introduced last year. We got a refund of the FT that was deducted in January.

As a kid brought up on the Apollo program and Fireball XL-5 these videos never cease to amaze me. Arthur C Clarke may have invented the communications satellite but Gerry Anderson invented the reusable spacecraft. All we need now is horizontal take-off and single stage to orbit. That booster has flown (and landed) 12 times! And for those too young ... And just how like XL-5 does the Space-X Starship look??

Yup, we've had a rather miserable on-off day too, still charged the batteries and export but just not so much as previously. Don't have our own AQI but the local online ones are bouncing off 60.7ug/m3????

Posts removed, let's try to keep a modicum of respect here.

"What would you like to do first, Kim?" asked Joe. "I want to get weighed," she said. They ambled over to the weight guesser. He guessed 120 pounds. She got on the scale; it read 117 and she won a prize. Next the couple went on the ferris wheel. When the ride was over, Joe again asked Kim what she would like to do. "I want to get weighed," she said. Back to the weight guesser they went. Since they had been there before, he guessed her correct weight, and Joe lost his dollar. The couple walked around the carnival and again he asked where to next. "I want to get weighed," she responded. By this time, Joe figured she was really weird and took her home early, dropping her off with a handshake. Her roommate, Laura, asked her about the blind date, "How'd it go?" Kim responded, "Oh, Waura, it was wousy."

Yup, been there, got the T-shirt.

Same with the little birds you buy "to set free", the ruddy things fly back into the sellers' cages where they get fed and watered. Unlike the people who buy them they are not bird-brains

There are an increasing number of on/off-grid battery-less hybrids that will work as grid-tie until PEA come along with the no-reverse meter at which point you shell for battery storage and tell PEA where to shove it ???? If they had been available when we installed, I would very possibly have gone that way.

Do you have a link??

One would assume it uses rotating machines so ought to add to grid stability. But TiT ... We came within an ace of having a waste-to-energy plant built just down the road, local protests scuppered that one, for now!

Yup. And a number of my Aussie mates are more than mildly miffed about it. Many are moving to local storage which (currently) isn't controlled by The Man.

Grid-stability is a big issue for places with a massive installed base of domestic solar (Aus for example).

The problem for MEA/PEA is where to draw the DIY line. They can't let just any old Chinese junk to feed energy into the grid, plus they need to know that the island-protection works correctly and reliably. HMHO DIY to a decent standard using approved kit (subject to an inspection) should be permitted, but the licenced contractors would be up in arms as their income would be shafted. Both our inverters are approved and my install is "reasonable".

There is FiT available. BUT It's not exactly easy to get on to (and one member has been waiting >2 years for his FiT meter), and a DIY system won't fly, need to use an approved installer and approved kit. Doing so will easily multiply your payback time by 4 ???? That being the case go hybrid with ESS (batteries) and have the advantage of never having a power cut, ever.

OK, a quick look at the manual suggests that it doesn't have a current transformer (CT) that would allow you to automatically control the output to prevent exporting energy ???? This isn't really an issue unless you find out that your meter is clocking up when you are exporting. Time for a test as detailed above.

Well, as luck would have it the 25th and 27th produced exactly the same amount of energy, 40.9kWh, so we can do a direct comparison with no correction for the control needed ???? 8.56/8.27 = 1.035 so a 3.5% increase, not as big as we saw, but definitely a movement in the right direction ???? Let's continue this experiment.

I'm talking to Foshan Neexgent but looking at the horizontal brush version, I hope it will be more controllable and I'll be able to use it to clean our upstairs windows without breaking out the ladder (so I can justify with Madam). A bit expensive at the moment but Yannis is "checking for a better price". We shall see.

If you clean your panels today (or first thing in the morning) and check energy generated tomorrow, we can use our system as the reference source (5th and 7th March). It would be interesting to see if the numbers correlate. EDIT Actually, if you can let me have the daily total for the day before and the day after your last clean (and the dates) we can compare now using our system as reference.

Yeah ^^^, I would certainly ask about it being at ground level. Just to confuse, our office has "G" as the at-grade floor but the next one up is "2". Our condo in KL had the entrance at "3A" (4 being unlucky in Chinese), it also had ... 11, 12, 13, 13A, 15 ... and the less said about the lift in our place in Ankara, Turkey, the better ????
