Victron have the RS450 Solar MPPT which can take up to (Do NOT go over) 450V DC, so that would be easy to do a long run. Or you could AC couple with a Fronius PV inverter which also works well with a Victron setup.

I seem to remember one of the manufacturers, maybe JA Solar? did different versions of the same panel, one for portrait and one for landscape, with identical spec but different length cables, maybe check if your panel has a twin with the longer leads. The data sheet will say which is which if that i...

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,...

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...

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...

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...

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...

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 ...

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 ...

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.
