I am thinking about placing PV panels on the roof but have a question. Because my FLM v2b have no spare pulse inputs, i have to use a current clamp instead.
Is a current clamp good enough for generation measuring of a PV installation ? Is it more accurate in comparison with household consumption (bad power factor at 0 consumption) ?
With the current Belgian regulations apparently, there is not necessary anymore to put an MID class kWhmeter to measure the generation to get certificates.
Another question:
If i could use port 6 to connect the SO output of a cheaper KWh meter, that would be a better and more accurate solution.
Is it possible to use port 6 as pulse input with a hack ?
IMHO no - see http://www.flukso.net/files/presentations/flukso.20121026.sensorboard.pdf
Wrt to using current clamps for PV consumption measuring - I would not do it again: see (for example) https://www.flukso.net/content/solar-panel-measuring-not-accurate - help yourself finding further information using the search engine of your choice with search term "site:flukso.net PV measuring"; see further https://www.flukso.net/content/ghost-current-clamp-zon1
Ok thanks for answering and read all the links now.
So, now i' am thinking of making a pulse to voltage converter to counter of my problem.
Using a din kWh meter with So output to feed in a small electronic circuit that i can connect to the analogue input 1.
I shall make another topic for that project ;-)
Be aware of the impedance necessary to interface correctly with the FLM's analog ports: 6k8 Ohms to get the correct range of the internal Uref of 1V1 via the integrated voltage divider of 1k91... But I guess, you know :-)
