ProjectEV - does the job cost-effectively. UI not as good as Zappi, but it works.

It does exactly what you suggest, effectively like the variable option on some granny and charge points. So much more flexible than on most conventional granny charger or charge points, but less so than Eco+ on the better charge points that will put all surplus production into the car.

Yes and No. The car will take the maximum current "advertised" as being available by the charge point up to 32 Amps maximum (or a lower limit when at very high states of charge and balancing). Some charge points have a "solar" mode where they measure the current available by use of a CT clamp...

About time that SEG payments were increased. Pity that this is another element of the market that has failed.

You need to check very carefully as it is unlikely that they mean what you are expecting by the term emergency power.

At present there's a big cost issue with the requirement for a Type B RCD - they are around £200 each in the UK. Adding a suitable Earth can sometimes be expensive depending on your circumstances. Point accepted as long as people observe the correct gender for the associated leads.

It all depends on your typical daytime usage, but it should be plenty. It should cover your background usage from storage alone in the winter allowing you to timeshift that to a cheaper overnight rate if such things still exist after the current Government madness.

I'd suggest that anyone thinking of doing this get professional advice as there's a lot more to it than this legally and safely.

The standards to do V2G via either AC (using the cars inverter) or DC (using an external inverter) connection exist, and both have been demonstrated with some medium scale public tests in the UK. But at present there's no commercially available charge point for either, and there's significant...

You cannot export to the Grid from an MG4, the only option is V2L to run some appliances with significant potential safety issues. The output may not be a pure sine wave and certainly not phase synchronised with the grid. V2G in the UK is currently only DC via Chademo, e.g. Nissan LEAF, with...

Spot on. V2L appeals to me as a backup as I've only 9.6kWh of battery storage at most yet rarely have less than that in the MG5 (the current non-V2L version) when I've finished for the day (for example about 30kWh at the moment on a Sunday afternoon, my house battery is at 8 kWh).

Most don't for safety reasons. To do it you need to "island" (disconnect) from the grid, swap to a local Earth, then connect specific circuits only to the inverter via a changeover switch with the correct type of RCD (B type for DC blinding protection). The alternative that some (including me)...

Strange that none of the screen shots of the central screen have shown this yet. Are the settings in the App repeating or do they have to be set each time?

Clearly time has mellowed the initial pain that this can cause. Early iterations of MG EVs had an issue with going to sleep which hampered stop/start charging. The main issues remaining are the manual intervention required to know when to stop charging - a 30 second break in charge early in the...

In most cases it appears to be very dependent on the car and the charge point. Clearly no-one here in the UK has been able to try charging the MG4 yet so we don't know.

It's not the kWp of the panels that matters, it's the export limit on the inverter. There's a number of issues with panels, in most of the country you rarely achieve close to the kWp of the panels because of the solar insolation levels, panel temperature, sub-optimal orientation/inclination...

The 300mn from the edges of the roof relate to safety for workers walking around the array and the stresses on the mounting system. None of them are absolute. The distance from the window is to avoid the risk of electrocution. Have you considered 2nd hand panels? Getting MCS approved ones...

Nissan LEAF batteries came with an eight year 70% warranty which has proved very hard to claim against. There's lots of 10 year old cars on 50% original capacity or less. Lots of previous GivEnergy and Growatt battery storage devices have failed in less than five years without successful...

No, there's nothing commercially available. As it stands V2L on cars like MG, KIA and Hyundai are not capable of grid coupling as there's nothing to make them run in the same AC phase. So the most that they can do is power specific circuits that are separated from the grid, either permanently or...

It all depends on what price you assume for peak rate electricity and the delta for off-peak. At the current price for new Go contracts it makes sense, but at the 2021 13.7p/5p it makes no sense.
