Charging using 32amp Commando and mobile charger

[PITA]

well, my main house breaker is 100 A

I think that is "default" capacity for new (relatively) builds.. Well my house was built in 2014

Here's an example...

If you do a Search on Google. Western Power had text in the results that said upgrade your Home to 80A or 100A.

But when you now click on the link, it takes you to the National Grid website... which only states 80A... no mention of 100A anymore.

Uk Power Networks seem to still allow it...

since we don't go over 0.1kW for everything else

You don't use more than 100W for everything else? That's unbelievable.

I could get down to that level, the main must have draw is the fridge and freezer, which vary from 50w-200w depending on temperature and whether they are cycling at the same time.

Fridge, that’s it really unless the car is charging.

No heating or cooling and no lighting through the night.

No electronics chewing up Watts just sitting there?

RCB tripped yesterday - only found out when someone texted me to say they were standing on the doorstep and had been pressing the doorbell!

Didn't realise which RCB until I went to bed in the dark and found light switches not working ... this morning I have 20% more in my PowerWalls than normal!

How did we find a torch without a flat battery / candle & matches, in the old days, when the lights went out? Phone-with-light in trouser pocket is a huge improvement ...

We have 103 connected WiFi devices, Four Freezers, Two Fridges, Heat Pump, two Wifi Mesh Networks, Firewalls & failover powered satellite dish, every single plug socket & light switch is powered 100% 24/7

That's our base load.

Then we have the heavy hitters on top of that...

Yes umpteen bits and bobs but only tiny consumption. I said 0.1 kW but I was erroneously basing it on the half hour metered consumption so it is actually double that at 0.2 kW … is that close to what other people see?

 

[qwickshot]

With a few exceptions, we turn stuff off at the wall when it’s not in use. Saves a lot of power when you add it all up. We’ve also been pretty brutal at cutting out unnecessary IOT devices that don’t really do anything particularly useful. While individually they don’t use much power, when you have 20+ all going 24/7, it’s a significant power draw.

Crikey, do you have a corner shop mini market with all those freezers?

Yes. I’m around 0.3 kW but I have a server running which consumes around 90 W. 50 odd Philips hue bulbs all sucking 0.3 W each when off also contribute. 4 Ring cameras, 4 access points, two fridges and normal things in standby such as TV, amp, oven, microwave etc.

Four Freezers

We grow our own veg, and have excess (that might not be your reason though ...). Storing that, for the off-season, comes up for debate each year. I have toyed with buying a dehydrator (the sort of thing that costs-quite-a-lot, rather than a warm air fan!). But we bought powdered dried veg, to see how we would get on with it (in soups etc.) and it didn't get used much ... so I'm not sure we would actually use dried fruit and veg.

But I might give up resisting more freezers so we can accommodate the abundance interseasonally. The cost of the freezer is one thing, the running cost 24/7/365 is something different. In Summer it uses PV and costs nothing, so I just need a power source for Winter. Wish I'd bought a house by a fast flowing river ...

Nope, definitely not. I'm nearer to 2kW

We are in competition @PITA.

We too have over 100 Wi-Fi devices and 15 to be added shortly in the consumer unit as well as two Powerwalls, 2 x heat pumps, immersion heater, and the usual DW, induction hob, oven and WM as well as CCTV, Starlink and 4 x 32A chargers....all running on single phase, but not all at once.

No, I'm using 1.2kW at night, without aircon.

Inflation busters...

You may already know this, so my apologies in advance if you do...

... but adding more chest freezers can require seperate 13A sockets for each one.

We added a new ring onto the Consumer unit with fused spurs for this.

Just don't chuck them all on the same extension lead with tumble dryers etc.

Co cellphones charging? No computers connected. No alarm system. no appliances with displays? No porch lights? You NEVER heat or cool? No water heaters? No clocks?

... and there is a vast variation in consumption between different households. We would not challenge that single phase limitation even if we were allowed 2 X 7kW chargers combined with our normal household usage, but there's no guarantee. If the usage was limited to nighttime hours we could run 3 X 7kW chargers without exceeding that limit since we don't go over 0.1kW for everything else ... but the calculations have to take account of different scenarios even if they don't happen in our own household. If we end up with electric heating in the future then that's a totally different ball game.

So rolling back to the original statement.

The way that electrical load is calculated really has nothing to do with what you have on when, it's what the probably load is.
And it doesn't matter what you do at night vs day.
Your electrical system doesn't have the ability to say, if appliance A is on, then I can't use appliance B.

The way that things are calculated for load, it's not how low you can go, it's how high can you go.
