This one is easy really. 1) The bigger inverter with or without more solar panels is a must, 3.68 kW inverter is nigh on useless, kettle and toaster on for breakfast = import from the grid. 2) The problem with wallboxes is if youre using an intelligent tariff eg Intelligent Octopus Go, they...

Until there's an efficient and cost effective way to harvest the Hydrogen it simply wont work because nobody will want to spend 3 x ICE cost for fuel. So many issues for aircraft and Hydrogen (or batteries for that matter). Hydrogen need a lot of space and batteries load carrying capability.

Having just been in a similar situation myself I can tell you its a nightmare to get MG to state your warranty is still valid. In my case, my supplying dealer closed, I had taken a service contract out with them so they suggest I went to another branch in the group which I did. It turned out...

No offence taken here at all, I'm used to people saying I'm wrong (even though it's untrue), I can live with that! Take care everyone. J

Clearly Terry has had previous bad experiences in the past, I havent had any such experiences using more modern equipment etc. Active balancers are in use across the board and the power supplies / chargers I have used do have voltage adjustment as described in my setup description when the house...

Correct but that isnt a problem, in my setup as the batteries approach 80% charge the current is almost zero from the power supply, The power supplies generally will have a voltage trim adjustment, I would adjust the voltage as above so that the house batteries wouldnt reach fully charged. Not...

And that is absolutely fine but it's not a reason NOT to have the discussion? Absolutely, the real consideration is that the DC voltage that come from the battery, the inverter wont care where it comes from, DC is DC no matter what as long as the voltage is ok then it will be fine. You are...

Well at least it gets some discussion going doesn't it? To be absolutely honest, the only time I have used our MG5 and the DC charging of house batteries has been during Christmas Day and Boxing Day. It has worked flawlessly without the slightest concern anywhere. The idea is really simple and...

Hence why I suggested that the system is started up and with house battery down at 75% the voltage from the power supply is increased until the required output current is achieved eg 40 amps for 2kW. If the load on the inverter is less than 2kW or Solar starts to generate, the battery voltage...

'Some bloke in Lincolnshire' told you it can be done with any batteries. The nominal 48v DC coming out of your batteries to the inverter is supplemented by another source of 48vDC from the MG4. The inverter doesn't know or care where the energy comes from, the batteries will simply see a reduced...

My BMW i3 has Sanyo cells fitted which guarantee at least 6000 full cycles before deteriorating to 80% capacity. My i3 will do around 130 miles on a full charge so, simple maths, 6000 x 130 = 780,000 miles. Keeping in mind this is what Sanyo guarantee, it's most likely a lot further than that...

all in line with the government we've got, absolutely no sense whatsoever.

To be honest saving the planet wasnt the primary reason. I bought EV(s) because I like the way they drive, the convenience of recharging at home and the very cheap running costs. I was spoiled 10 years ago when working in USA I was given a Tesla Model X as my company car, I had to do regular...

It really makes no sense at all. My i3 has a Range Extender so it's classed as a Hybrid but I never use the REX. In 2028 when the 3p per mile comes in, I gain again because it's only 1.5p on the i3. Typical of this government going from one ill thought out disaster to another.

Preparing a smug grin here, my BMW i3, 12 months tax is £20, happy with that :D :D :D
