Random Renewables Thread

 "Having the manual isolator in the attic a half mere away is required and a solenoid operated one in front of (or after?) the manual one seems overkill."

Always after the shunt.

This image from an Irish supplier. It shows what appears to be a remote isolator directly under the roof apex, from there to the DC isolator on the left, then into the cable duct. AC isolator

on the right. A current MCBO beside the DC isolator, probably leakage/overload to the grid, this could be in the consumer unit of it had space. High DC voltage still inside,however short the link from the panels.

I was wondering about the battery, are they DC breakers. I was only seeing high current terminals, on closer look theres a small lead sharing the red terminal flexible conduit, is this a mains connection to the battery MS? I could look up the Dyness installation to see, but I've one eye on Brighton/Spurs...

Not directly related to renewables but finally got around to replacing a condenser dryer with a new heat pump dryer.

Just comparing the power usage of a similar load that used use over 3kW to dry now takes just over 500w

I don't use a deep fat fryer but I imagine they use a good bit of energy getting the oil up to temp.

An air fryer uses about half the energy per heating cycle compared to a fan oven and cooks quicker.

Can't remember the last time I batched cooked chicken nuggets!

I do think it would have been a great investment for the Government to send every household an energy monitor as part of the energy credits package as part of the last few budgets.

A lot of people here have became a lot more energy usage aware due to solar etc.

Gobel has some new looking DIY kits, they're a different format with 2 rows of 8 cells stacked on each other. There's another one for the bigger 628Ah cells too

I don't know if that's a see through case or just a cutaway graphic. I guess it's still in the development phase since they don't have any real photos

Its a neat looking case, the smaller ground footprint might make it a bit easier for some installations. I'm a bit confused about the positive and negative sticking out of opposite sides. Good for separation but I'm not seeing the logic behind it

Time of use for exports would be a great fix here. Give a peak export rate between 5-9pm to encourage anyone with a battery to discharge to the grid when it needs it

Similarly you can have a lower export rate during the night time to encourage people to store any energy they have

Well whatever your night rate is is basically just an abstraction of the market rate during that window

2-5am is cheapest so gets the lowest rate (although I'm convinced Pinergy lose money on that rate). As a recall it's around 20-40% of the day rate for most suppliers

I'm still on the old D/N rate so I've got 9 hours of cheaper electricity, but the difference is narrower, around 50-60%

And illuminated coloured cooling fluid in transparent tubes!

I think I'd have preferred the front to be see through and the top and side to be metal with the display and terminals mounted on them

I do like the format, and the idea of a non conducive outer shell

Maybe Andy will get one and give it a review at some point

Assuming your inverter can talk to a JK BKS then it should be able to replace an existing battery

If I was buying today I'd probably go with the metal kit as this is a proven product. A lot of these kits have some issues when they launch so I wouldn't want to be the early adopter

It's worth checking out the off grid garage page as he links the sellers he has bought from

It's worth keeping in mind that you'll pay VAT and customs charges on most stuff from China unless it's EU stock, so just be careful about the headline price
