Yes, they distributed Waitrose for their first 20 years. Then (since 2020), is a joint venture with M&S. So full range of M&S products as well as Ocado own-brand items (y)

Ocado's robots are much better ;)

Only those of us with a TT earthing arrangement, usually rural with overhead supply. Most households in the UK are supplied with underground power and TN-C-S earthing arrangement.

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!
