Glad I shop online :)

The AC coupled storage inverter may have an AC backup, but it would not be connected to the AC-grid connection that the micro-inverters are connected to. Even with suitable switch-over circuitry, you wouldn't be able to trick the micro-inverters into using a backup grid for the reasons I...

Yes, but won't offer the same capabilities and works out more expensive. If there is a power cut, the batteries won't get charged because the micro-inverters will drop out due to no AC grid. I see. There are many hybrid inverters with greater power output though. e.g. Solis, Sunsync etc.

(y) voltage drop is so often overlooked as being a design factor.

Me neither, unless there are mitigating factors. Cost of adding battery capacity becomes much more expensive with micro-inverters and you have no capability in the case of power outage. a) Note to self... must book in with spec-savers :eek: Not sure why you say DC-coupled (i.e. hybrid)...

For those of us who can choose or make a suitable high quality extension lead; for example using quality heavy duty plug and 2.5mm2 arctic cable or similar (as discussed - see link below), then I agree. But, from my experience the vast majority of extension leads are not suitable for sustained...

My 2p worth... a) Go for the maximum number of panels you can fit (obv. limited a bit being a semi) b) Do an energy audit prior to specifying your system. Specifically what is maximum power draw (in kW) and worst case daily energy usage (kWh) in order to size a) the inverter's output power...

To clarify the point; the law was made for all fixed installation 7kW+ chargers. It does not apply to portable or granny chargers. The reason is to enable intelligent charging controlled by energy companies in order to help balance grid usage as there becomes more and more EV uptake.

:eek: 🙅‍♀️ absolutely not! A fuse will only blow when there is significant overload of current flowing through the wire (as I recently detailed in this posting; see the detail and graph in that posting). A fuse will not protect you from a fire due to overheating of a bad (=high resistance)...

You win.... Wind = "the perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction." :cry:

Nice; 2kW of heating for 7p/hour (y)

The pedant in me wonders how fast you reverse to call it a windscreen ;) Either way, your rear screen is probably not dirty because you fitted a new one recently!

Me too - we'll be driving for zero cost from now until about October thanks to the sun. (As in the big nuclear reactor, not the rag, that is). (y) I hate charging to 100% for just that reason. I then find myself lifting off the accelerator about half a mile before the next junction to avoid...

That was quick! Maybe the new owner just got rid of his 3 litre Disco that did 25mpg and cost over £600 in VED. That would make an XPower a bargain. Hope the new owner checks in on here (y)

The grid in general will have low demand, yes, but if there is a high power demand of off-peak power (e.g. EV charging, Home battery top-up), on your local wire, then likely would be lowest voltage then - as @5teep mentioned above.
