I’ve used practically no grid at all the past few days
But is the Solis inverter drawing power from the grid all the time despite the batteries being full and Solar available?
See my Monday chart from the ESB
At no point would the batteries have fallen below about 40%
Why can’t it take its juice from the panels or batteries? Or is this a draw to check the power is on and quite normal
I know this is tiny but I don’t want to be using any grid when using no grid is possible
That must be a setting. I have a solis 6kW hybrid inverter and it doesn't draw from the grid that much. Only when not receiving any solar at all (as it is slow to react to demand change from battery alone)
Thanks
Solar production is incredible today and it’s not even fully sunny
13.536 kw out of the panels now at noon ,max is 14.820kw
My Solis will always draw something while the battery is charging it seems, now it might only be 0.02kW or something, but its never 0 until the battery is charged, regardless of solar output.
Meanwhile, 19kWk the each of the last 2 days, 11kWh so far today
7.2kWp in south dublin.
44.4kwh so far today in SE Wicklow and still going,should get over 50
The highest since install in December and super I believe for March,delighted
Broke 11.5kWh today for first time this year. Feb now generated more than Jan. Dublin 3.1kWp system. S and W.
Total got to 51.8kwh
Cracking day here today with just over 46 kwh generated today. Rest of week looks promising too
New daily record here since the install in October. 21kWhs on 4.4kWp
off the charts here also today
2 things are coming into their own now
Evenings and overnight are totally on Battery a lot lately and there’s plenty solar power during the day to power up some storage heaters \0/ for evening heat
That's 0.5 of a kWh....what are you worried about...there might have a 15 minute spell during the day where you had the kettle on the oven etc and it drew half a kWh from the grid because you went over the power limit of the battery/inverter. What are the numbers for the rest of the week
+1 on what ECO mentions, however, the more likely reason is that there is a delay of usually 10-20 seconds from when a load comes on to when the inverter can pick up the load from the battery. The delay depends on the inverter model, my Givenergy can be as much as 30 seconds, although the specs say 10-15 seconds. During this time any additional load like ECO mentions a kettle will be pulled from the grid.
Was gonna say the same bullit. I think! AC power is travelling back and forth in the mains supply and our house wiring 50 times per second. Difficult for an inverter to react instantly.
My inverter uses WiFi and I can't get usage below 1kWh per day as I think the WiFi is slower than a wired connection. I also don't give a fork because 1kWh is almost nothing.
usage Monday was 0.5kwh
It’s also a failsafe the usage if your inverter is not in island mode,it has to know there’s grid power lest you electrocute lines men
I think in that case, the inverter is measuring voltage, not power.
Well it’s taking some grid to ensure the grid is on isn’t it so it can shut down supply if the grid goes off isn’t it
Some inverters just run at a slight import when on batteries.
But it's not for grid detection, that's done by other means, voltage, frequency
No, it's not. It doesn't use power to ensure "the grid is on".
Best day of system so far. 37.5kwh south facing ground tubs. 7.92kwp.
Would have got to 40 but heavy cloud 330 to 430.
Best day of the year here. 17kwh.
Everyone getting their best day of the year yeah? 15 here on a 4.4 system, e/w split
Same, 40.6kwh, best of the year so far…. 7.2kwh South facing
13.9 kWh today for first time over 13 this year. March well past Feb ages ago.
Dublin 3.1kWp system. S and W.
32.9 in Inishowen, Donegal from a 5Kw system, South South West ground mount
36.3 on a 7.73kw WSW setup in Cork. Best by far since my install.
24 kWh on a 7.04 system 16 panels split even E/W highest so far since install in October 24
Just got the inverter and electric done yesterday so today was the first full day of production. 25.1kwh on a south facing 4.4kw system. Well chuffed
A lovely day in Cork city, 31 kwh generated on 5.5 kwp South facing
40.8 kWh generated from 8.9kWp south facing system in East Cork. Could possibly have been more but my batteries were full from 09.30 to 17.15 and I assume my generation was being clipped. If days like today continue on a fairly regular basis I might not charge the batteries to capacity overnight on the EV rate.
Nice to see all the high numbers and yearly records being broken.
First time breaking the 40+ ceiling today with 46kwh
