Thanks, part of the thesis will be to see how it might work and what is going to be the best way forward to using renewables, storage and the grid together. Well, if I can be forgiven for mentioning companies who are working on the subject, it might be worth your while doing some research on ITM. h...

There's talk all the time of PVs coming down in price in just the same way as EVs having 300 mile ranges but do we actually see these make it to market? Not quite. The talk of oversupply is usually all in the financial press. You know the likes of the FT or "Shares" or the Investors Chron...

It's been done many times by many people. You don't start with the batteries though. You start by evaluating your needs and making energy sa...

mainly because AC is a killer esp at high volts - and i dont like messing around with it I'm no engineer but I'm pretty sure that DC is a whole lot more dangerous than AC at high voltages....

Cheers guys, confirmation enough for me. Paul, when you say leisure batteries, I assume you mean golf cart type packs? Usually it's taken to mean Caravan batteries, or in some cases light boat batteries. Semi deep cycle, but with expectations of some high current usage. I myself would include golf ...
