Interpreting numbers in InsightHome

[ssgp]

I have some questions about the reported energy.

Attached you see a Daily report with Nov 9 highlighted with the pull out box. In it we see the following:

PV Input: 4.9kWh
PV AC Output: 2.9kWh
Grid Input: 7.6kWh
Load Output: 8.4kWh

From this my understanding is that we collect 4.9kWh and are able to convert that to 2.9kWh due to the conversion from approx 48-60VDC to 220AC.

We took 7.6kWh from the grid, which together with the above AC output covered the 8.4kWh of load.

My question comes from 2.9 + 7.6 = 10.5kWh but we only needed 8.4 meaning 2.1kWh are unaccounted for. With the high efficiency that you claim, I get that to a 20% loss.

Where am I going wrong?

Also, are the MPPT60's displaying the total input of all or per controller?

System specs:
1 x XW5548
1 x MPPT 100 600
2 x MPPT 60
1 x InsightHome
1 x PDP

Also, is it a hard coded timeout for the UI or is there anyway to modify it?
Frankly it is very annoying and does not make any difference for my set up as the system is not on the internet. An option to set the timeout and turn it off would be good.
