That's a good start.

20 lt/min = 0.33 kg/s I got that from here: This is to get an idea of the power that the ASHP is capable of delivering.

You could integrate some PV into your roof, that works out cheaper than slating.

4.2 [SHC of water kJ.kg-1] x 0.33 [flow rate kg.s-1] x 4 [delta T] = 5.6 kW delivered to the house. This seems very low, what size is the ASHP.

If you were in Cornwall, you would notice piles of roof slates kicking about the place. I often wonder if they sell them. Just down the road from me is a farm building that has been slowly crumbling for decades, such a shame that the roof was not reclaimed.

Tis may be a clue. Are you loosing temperature to the floor where the pipes run? Get a cheap IR thermometer and see what the temperatures are in the areas around the pipes.

Welcome Only one person, that we know of, has managed to escape from his dungeon. Lockdown can be interpreted so many different ways.

Only for a few days, the rest of the time it is lower, or higher. Probably lucky to make 6 kWh/day in December.

Does seem odd. Taking a trivial example: 4.2 [kJ.kg-1.K-1] x 2 [kg.s-1] x 5 [K] = 4.2 kJ.s-1 = 4.2 kW. Would make the flow of the system critical in delivering power.

Should be easy enough to swap the wires over

It would show inverter consumption, if there is any. Why don't people just buy SMA inverters and have a trouble free life.

Are you thinking it is wired in back to front?

They do a Bluetooth adapter. But it is really down to what Growatt want you to see. You could make your own, friends how much playing you like to do with basic hardware and software. Or get a CurrentCost and a Raspberry Pi Zero and ask for some code.

Make sure this is set right.

Then it is not vital, though it is useful as an accumulative total. Or to stick a CurrentCost onto.

FiTs or equivalent for your exports.

Is it just showing the last hour? Then a daily total, and a weekly total.

This is a bit more concerning as if you are claiming from your energy company, this is the numbers then need.

This could be the instantaneous power, 186W, which if it was a little higher for an hour, would be 0.3kWh.

Snow on the panels?

Interesting. I wonder what happens if you use a local network, with the settings on the phone, then the power goes when you are out. Not sure if that would be an unusual scenario or not.

Yes you can, my mobile phone quite often connects to the St. Marys' transmitter as well. And I was at Land's End yesterday evening.

If you have programmed the Shelly to come on at a set time, and then you have a power failure, does it keep the same state i.e. on, or does if fail safe i.e off. And can it repickup any times that are set? Or are they done on your phone/cloud?

No, I live in the poverty stricken, overpriced, far SW. Yesterday I was looking at the Isles of Scilly.

How do I get on this scheme?
