Eh ... 0.25!

At the time I don't think JPEGs existed, and it was USENET ASCII art sex pictures (often involving animals) that caused me a certain amount of bandwidth grief... Rgds Damon

Agreed with Steamy here... I used to have a continuous load about half of yours, partly from still running an ISP: https://www.earth.org.uk/saving-electricity.html#2007-07 In the end I squeezed everything I needed into a Raspberry Pi (well, I'm being extravagant and using two at the moment!) and it has run completely off-grid for over a decade, by drawing ~2W. Rgds Damon

FWIW I power my Internet router off-grid, though at this time of year it's quite tough (typical domestic router is 12V @ 1A, ie 12W, or ~0.5kWh/d). https://www.earth.org.uk/battery-bank-replacement.html The primary jof of that bank is to keep my servers off-grid all the time, which has been for >> 10 years. Right now the router (the 'dump' load) is back on mains. http://www.earth.org.uk/_off-grid-stats.html Rgds Damon

10l per second per person seems a reasonable goal, including for covid! We are managing (though with humdity somewhat too high) on about 10l/s/p for *four* of us. You should defintiely NOT be worried about Oxygen levels I suspect! https://www.earth.org.uk/MHRV-mechanical-heat-recovery-ventilation.html Rgds Damon

As of today I have gone from ~1.25kWh of ac-coupled Enphase storage ("AC Battery") in early September to ~5kWh today. (Well, configuration isn't complete, but the physical installation is done.) This is for science in the sense that I'm pretty sure that this is larger than optimal, especially in winter, but I want to found out if that is evident from the stats. Rgds Damon

Ha! One step in the right direction! I had the Combimate fitted today (within a couple of hours of the package arriving!): https://www.earth.org.uk/note-on-solar-DHW-for-16WW-UniQ-and-PV-diversion.html#2021-10-11 Rgds Damon

In case it is useful as a data point, my family of four in London uses per year ~2MWh electricity (gross, ie ignoring our PV, import is about half that), ~2MWh space heat and ~1MWh DHW both currently gas. Heated floor space 76m^2. So to me 12MWh total, even just using crude electric resistance heating, feels high, allowing for London vs up north (I haven't lived north of Edinburgh though). Conservation is by far the cheapest energy source. Rgds Damon

Octopus just got another $800m or so in funding in the last few days, AFAIK. So you be able to cover your supply for a bit if you notch down the Jacuzzi temperature...

Not at all. Carrying internal loads to avoid/reduce imports from the grid is what mine do, ie increase self-consumption. Rgds Damon

You will need the permission of the FiT administrator to connect it, and if you are being paid an export tariff (non-deemed) you would additional need to satisfy the administrator that there will be no export from the battery to the grid. IMHO. Rgds Damon PS. I have PV plus separate storage for the grid (and other off-grid): https://www.earth.org.uk/img/PV/Enphase-Energy-Storage-Diagram.pdf

No, though they are probably available, given that the manufacturers are reputable (Victron and Enphase). Rgds Damon

For anyone interested, I also increased grid-coupled storage by ~1kWh, and it seems to be strutting its stuff so far: https://www.earth.org.uk/Enphase-AC-Battery-2.html Rgds Damon

Given all the covid delays, and the fact that I finally got done two electrical storage updates this month (on- and off- grid), I now want to reschedule my heat battery plans for Feb/Mar/Apr next year: https://www.earth.org.uk/note-on-solar-DHW-for-16WW-UniQ-and-PV-diversion.html Any suggestions as to who might be happy to do an install etc? I'd probably ask Sunamp for a unit with stats available (if such a thing is possible) so that I can integrate it better with the rest of my storage and monitoring. So I'd be a technically-savvy but inquisitive client needing schematics etc! Rgds Damon

It's all done and installed, thanks for the advice! https://www.earth.org.uk/battery-bank-replacement.html Rgds Damon

Protective elements in the iMac power supply absorbing nasties injected into the mains by the electric fence box? You are likely incrementally damaging the iMac and any other electronics (including LEDs) on that supply. I would take one or the other off that supply ASAP, at least temporarily, and get something like a UPS in front of your iMac to take one for the team. Rgds Daon

Surely one has to "hearse" first then "re-hearse"? I guess you could "pre-hearse" before all that... Rgds Damon

I don't know what the fuel mix is now, but https://www.vikingenergy.co.uk/the-project and https://www.nsenergybusiness.com/projects/shetland-interconnector/ would move the needle rather significantly! Rgds Damon

1) This is about the *user* of the system not needing to use a computer interface (eg on a phone) to be aware of status. 2) I could run this entirely through the WiFi on my RPi3 which is entirely off-grid: the router sometime is. 3) The router stays on anyway since I serve my main sites and services (DNS, mail, etc) from home rather than a data centre. It is partially off grid, but is nearer 10W as I measure it right now! Rgds Damon

Yes, so this could be customised to get round that. For example, I also dim the light somwhat when on red. Rgds Damon

Because this is intended NOT to need a computer running and screen on, eg to give a hint when thinking of turning the oven on, etc. Rgds Damon

Because National Grid looks after the GB grid. NI is managed as part of the all-Ireland grid. Rgds Damon

In case this may be of interest to some here: https://www.earth.org.uk/note-on-Green-Light-Signal-and-Beyond.html "Using some low-key IoT and WiFi magic to try to reduce electricity consumption at bad times, inspired by the UK's National Grid!" Still in progress, but I'm out of puff for this evening! Rgds Damon

So, from the info here (thank you) and the thread here: https://www.fieldlines.com/index.php/topic,150367.0.html at the end of the summer I'll likely get a 220Ah Victron gel: https://www.tayna.co.uk/leisure-batteries/victron/bat412201104/ or, if being a bit more bold, 1 or 2 Firefly AGM: https://www.macbethenergy.co.uk/#/ I'm likely also to add more to my Enphase grid-tie, and if I can manage it, Sunamp heat storage! We'll see! Rgds Damon
