Re: affordable grid-tie wind?
I did ponder the Future Energy turbine at one point, I think someone here has one?: https://futurenergy.co.uk/feshop/airforce-1-wind-turbines/ , but we don't really have a suitable location. It's not grid tie though. If I did have an ideal site I would search for a DC coupled 2kW second hand Bergey,...

Re: I didn't top balance my packs before installing
You can also use overvoltage as long as you don't overshoot charge termination tail current {50mA @ 3.55V}. I would urge readers not to do this! Unless this post was for people with only 15a/h cells, then a 50mA tail current @ 3.55V would be fine, but definately not for Lf280K or MB31's! Look at th...

Re: Insulated Bath
I'm sure I read recently some advice to put the bubble bath in as you run the bath to get a good layer of insulating bubbles on the surface. Seems to make sense as I'd expect more heat loss from the surface than through the bath itself. I also prefer showers, the only time my bath is used is to rin...

Re: Insulated Bath
I am informed by family who live out there that in Germany this is how every bath comes. Cut outs in the insulation for the plug holes. I did ours in the old house. Made a massive difference, and should be standard procedure as far as i am concerned. I used the penosil spray stuff for the battery s...

Insulated Bath
I'm building our new bathroom and thought I may as well insulate the bath, in the hope it will keep the water warmer for longer. I'm not sure if it will make much difference, but I had some Penosil spray foam in a can I wanted to test anyway to see how well it really does spray and it was ok! Are in...

Re: Pre charge resistors
Can I ask what this circuit is for, never heard of it before. Just interested that’s all "This circuit is designed as an inverter disconnect that allows the user to pre-charge the inverter capacitors before fully turning on the system." To stop huge inrush current arcing across cables or ...

Re: Pre charge resistors
Yeah, I have a 24V system so used these 25W 15 Ohm resistors: https://amzn.eu/d/0cQ2cqf But in general a pre charge resistor for: 12V: 6 ohm(min) -15 ohm, 25W 24V: 15 ohm (min) -30 ohm, 25W 48V: 30 ohm (min) - 60 ohm, 25W I made a push button pre charge circuit based on really helpful download from ...

Re: Trials and Tribulations of Eco installs.
If pipe inserts increasing resistance is a consideration for standard dimension plastic pipe, use Hep20, their inserts are very thin wall stainless steel so minimal restriction, I prefer them because of this myself.

Re: Trials and Tribulations of Eco installs.
Wow, I feel for you, I've been fighting with my plumbing recently and I'm no plumber but that's a shocking install, I hope you had a few dehumidifiers and some strong beers! At least now you've pretty much sussed the system and are practical enough to fix it yourself. +1 on the Cat alarm! I love the...

Re: Its a tad blowy
That was a neat folding trick.Incredible it didn't rip, tear, and fly off sideways. [Trying to find a positive side.] Yeah, I'm glad they didn't take out the wheelhouse with them! With sound on it's quite a crash! I was trying to justify buying the perfect sized panels to fit the roof before, but t...
