Hi all, does anyone know about the following?? The MCS manual says a type B RCD should be fitted if the inverter is capable of feeding DC current into the grid, but a type A is ok if the inverter has "at least simple separation between the DC and AC sides" Hagar want over three hundred qui...

Thanks Fintray :D Deep joy, now we have the other six panels up on the lofty roof, so the full 4.8kWp is live, still no smoke, flames, arcing, or anything, just lots of lectrons being persuaded to mingle with the battery. So if a million square miles of Strato - nimbus invades the British Isles .......

Commercialisation of sodium ion batteries is a big deal due to abundance of materials and low cost. I'm surprised, if heartened, to read about their usage in vehicles, as I expected them to make inroads into the storage market primarily. Will follow this with interest. My brother-in-laws collegue a...

It looks like I've got to go with the tunnel through wall option, with a flap at both ends - and possible some sort of antechamber - although that could wait til next winter... Thanks I know what you mean about KI...

We have one of those electronic chip activated flaps for "Offcut" which when locked doesn't get blown open even with the wildest wind. When new before the seals around the flap get too grotty it is reasonable wind proof, and TBH I accept the small airleak as part of the adventitious air re...
