Just an update for those polyphase customers in NSW/Origin getting an Atlas Mk10d nett meter.
Ours has been in since 22/2/17
There are a few meter codes that seem to be crosschecks of other readings.
INtL = net solar kW you export.
This is the total of the three INL readings, which are net generated and not used on each phase. I assume there will be only one INL reading (INL1) if you have a single phase inverter. Ifyou have a 3-phase inverter you might have readings on all three INL codes. See link for explanation. https://www.queenslandsolarandlighting. ... -property/
EHtL = net kW imported into your property from the grid.
This totals the three EHL readings, which are cumulative loads on each of your phases. (EHL1, 2and 3).
INP1 is your inverter gross generation before it is used in your house.
So with some basic maths you could use INP1 minus INtL to give you what portion of your generation DID get used to cover your loads thru the day. In my case 120 - 89 = 31kW solar used on property. The 89kW is exported @ 6c/kW.
You can also estimate total household usage by adding the EHtL (60kW) to the 31kW but you'll only pay for the EHtL. Plus any hot water on off peak controlled loads.
Hope this helps!
