Its a similar issue to monitoring a battery, can only look at that in the one direction which is a shame. However I guess that with some manipulation in Excel with downloaded .csv data that may be fixable. Having said all that it is a very useful tool as our solar monitoring app from Moixa has questionable accuracy so having two or three different monitoring sources does help.

Hi Good morning from North Herts in the UK just north of London. We have been getting plenty of solar input. We have 14 panels installed with battery since 2018 and now looking in more detail at our stats. Sadly we find that the dashboard for our solar is as much as 25-30% inaccurate. So purchased Vue with 16 CT’s so we can get more accurate figures. Of course totally impossible to fit many of the CT’s in our MCA board so operating safely but with cover off inside a lockable metal enclosure. Thats another story…  so right now just using it to measure our solar and battery feeds and doing a proper safe job on all the MCU circuits will be looked at later.

On our line diagram we would like to have CT’s at A, B and C as well as ultimately all the circuits on the MCU.  We have enough of the 50A clamps for that though theoretically and B really could be using the 100A clamps.  also we would like to monitor the battery which is fine using a 50A clamp.  Given that power can flow to/from grid from solar or battery and also measure total household usage  (clamp A). We are also thinking of installing a second solar generation system with battery and inverter which would be islanded (eg purely for household use) – possibly we might use a separate Vue monitor for that although one of the possible suppliers assures me they have very accurate measurements through that systems own dashboard.
