So love the untracked energy and using another integration and also custom config bits i can assign and track some devices also.
One thing I have noticed though is with House Batteries that when the batteries are charging I see increased “untracked consumption” load.
I’m fairly certain I have most things tracked, and this is over night also. There seems to be a pattern for when the batteries charge, there is an increase in untracked consumption.
I have already worked out the typical base running energy for the inverter by isolating the house circuits, down to just the battery system, and located around 20w is used supporting the system (brown).
I do wonder if there is a BUG, OR if others see this and if so could it be round trip loss being tracked? ie Power consumed/imported by the system, and the result stored, with the difference being round trip loss associated with the AC/DV conversion?
FYI the grey untracked to the right are after we wake up and things like the lights are on, hair dryers used etc, etc so those on the right are expected. So there’s something certainly not making sense.
Do you know that your solar converter loose energy while converting DC to AC power? So if your solar power increases you also loose more energy. Same for when your battery discharges.
I See that on my system as more solar I get the higher my power usage is shown because the solar system “uses” more energy.
We don’t get it for the Solar, as our solar is not a Hybrid setup. Both systems are separate. We see it on the AC couple battery side. If it is due to round trip loss, it might be a cool one to find out and have it allocated. ie battery Input, v’s what ends up there, and having the difference proportioned to round trip loss.
I assume your inverter uses smart meter for total energy spent by house.
The solution is to have additional device measuring house circuit excluding the invertor. Then you can create a sensor handling the difference (losses)
The calculation is very simple. It’s total - (all configured separate devices) = untracked values.
There’s nothing more to the calculation. If you’re getting odd results, chances are you have something wrong with your total or an individual entity in the separate devices reporting too much.
considering he tracks all possible devices. which is highly unlikely.
but Inverters are hungry. Mine takes 2.5 up to 4kWh daily.
What do you mean by this?
It’s not about splitting inverter. if the Inverter is connected between grid and switchboard cabinet (even inside the cabinet), it’s possible to rewire connections in cabinet to measure draw on house side (between the inverter and devices)
The issue splitting is in the consumer unit there is a big breaker that provides a submain to the battery system inverter and the solar inverter system, so i cant just isolate the battery one.
And inverters dont sit grid - inverter - CU. They are Grid - CU - inverter.
We have ct clamp that full measures the house load. Most things are tracked bar lighting. However there iant any on at night so rules out the untracked ones
@petro the untracked increases disproportionate only when the battery system is charging.
Yes, that means you should fix the discrepancy on the entity or remove it from your tracked devices. How will HA know when the battery is charging when the calc only see’s the kWh?
I’m not sure I follow. I’m not actually tracking the battery system as a separate device as such. It was added to the Energy dashboard just like Solar and gas and such as was intended. But there is a strange issue forming that it’s all balanced fine - If i really try and make sure the very few devices and lights are off, i can get Untracked to nothing. But if the battery is charging then untracked use is “invented”. As soon as it’s not charging this vanishes…
You are tracking it because you added it to the energy dashboard production if you put it in solar. That means HA will treat it like production and it will be added to your total. I.e. don’t put it in solar, or make a template entity that removes the battery surplus and add that sensor to production.
don’t isolate battery. measure energy between inverter and the house. Battery is not the only source of the difference. Inverter falls to those equation too.
Thats the calculation i assumed it was. I just don’t know why when the batts running fine theres no untracked, when nothing else changes and the battery is charging there is extra unknown untracked consumption. The battery is isolated from solar generation/production as its a sole ac couple battery.
We tripped everything off and found thst the inverter uses 20w to run so we appropriated this constant 20w as inverter use. Its just when charging we seem to get increased untracked occuring.
We also can see live the house use, wha the battery is outputting and the difference that is being used. This extra untracked occurs juat when charging and not the rest of the time.
