Tomorrow looks like a full sun day..............
Yesterday, 18th April, new record for me 29.6kWh generated from a 4.8kWp on a south facing roof.
Today looking a bit cloudy but tomorrow could top yesterdays.
No bother! I've most of my house on the backup supply. The larger loads such as cooker, immersion and electric shower are on the grid parallel supply. When they're used, I see load on the new grid side load GUI. The problem is, the backup supply now has no real time monitoring. Before this, they were both combined, as it should be. Solis Home has them shown individually, but they're shutting it down end of April.
Once this inverter needs replacing, I'll be going with somebody other than Solis. This is just the latest time they've irritated me.
It does. The CT is on the incoming grid supply. It's directional. If it detects incoming draw, the inverter will try to supply the load. So your small shed PV is taking the load, and your main house invertor is seeing no load, so the CT reads 0, and will export what excess power it has available, or charge the battery if it isn't full.
Makes sense now to me. Thanks for the explanations. :-)
Probably going a little off track for the "Daily PV production", but I think the inverter doesn't definitely measure house consumption like that. It depends. Take me. I have a shed installation which my main installation knows nothing about. If that shed generates 1Kw, then I see on the telemetry on my main installation that the house load has gone to zero. E.g. take yesterday.
House load was actually zero watts (nothing!!) around lunchtime.....because the shed PV was supplying all that the house needed. So because the main instllation saw that nothing to import from the grid, the main installation "thinks" the house load was 0w, but in reality the same devices were plugged in, etc. That's how it "computes" the house load.
No. The invertor measures house consumption, and supplies the exact amount possible so the house load does not pull from the grid, and to not drain the battery to the grid. If it's producing in excess, it exports. If the house load is more than the inverter can supply, the grid supplies the rest. Notice the grid side load was 0 kWh in my screenshot. I'm not seeing my house load at all now, I used to know exactly what the house was pulling in real time.
Someone can correct me here but my understanding is that the inverter measures how much it sends out towards the house CU (and how much is drawn by the backup/EPS circuit). It also senses from the CT clamp how much is going to/from the grid. It then assumes the rest is going to the house - so the house consumption is just a calculated figure and assumes that no other source is involved. In my case I have a string inverter which my hybrid does not "see", but which feeds straight to the CU and hence grid, so my "house" consumption is meaningless.
They do. The invertor has two outputs, one that runs in parallel with the grid supply, the other backup supply which is UPS capable and isolated from the grid. If the Invertor didn't at least augment the supply of the grid load, or as it should ideally be doing, taking the grid load on completely, there would be no point having PV unless everything was run through the backup supply out.
Graph now makes more sense to me. Grid loads dont go through inverter at all.
18th April, Newcastle Galway
31kWh generated
6.23kWp on a roof SW-facing roof (azimuth 239°) 30° pitch.
Alpha smiles 5 inverter with 10.1 kWh battery
Huh?
20.5 kwh today from 3kw sw, 1kw ne in north kildare. Highest since the sw was installed. There was some cloud mid morning and after 3pm. 25kwh looks possible this time of year which is a bit of an eye opener.
A cracking 53.4 kWh today, Kildare area south facing 22x400w, happy days 🙂🙂⚡💡⚡!!
A meager 26.1Kwhr for me where I'd forecasted 30.4Khr. Some clouds would just not bugger off in the morning, but battery full, washing done, immersion tank hot, what's not to like?
Tomorrow (Weds) not as good as today forecasted, but Thursday looks even better than today at the moment.
37.8 kw generated. 1.2kw consumed today 🤯
Overcast in the morning but did improve a bit later in the day. Finished on 16.9kWh, a good 10kWh short of forecast.
20.5 today. Highest since install.
I am 12 away from the 1000kwh mark.
45kwh today, new record of the year, would have been easily 50 if the clouds didn't roll in.
Best part, 0 kwh exported 😎
Today was a good day,
Happy to be back moving on the barley seeding!
Belter of a day from about 10.30 onwards. Delighted to say PV generated 21.3 KWh today. Lets hope tomorrow will match.
41.5kWh Today, best of the year to date.
PS: Anybody know why Solis did this to their app? They used to have grid side and backup supplies combined and displayed at the bottom right, which made sense considering it's all just consumption.
here's hoping to see a graph like that in mid-Galway on Thursday but I've learnt to temper my meteo expectations!
22kwh today - Thats a first for me.
26kwh thus far today at 15mins to 4pm.
Graph is very interesting, it's been constant sunshine today with very few dips. Hardly any cloud cover.
This is from a 6kw array South Facing.
Blue sky here but that poster probably has silver sky (overcast)

Most of the country in blue skies - your unlucky wherever you are if that's the case :-(
Unless something changes, it's looking like I'll struggle to break 9kWh today. :(
You need a bitcoin miner :-)
My forecast is showing 27.5kWh. I'd expect about 30% self consumption as the car is near full so that leaves Eddi and the battery.
