I have a3 phase victron ess with mp2-48-5000-70 and 4x pylontech 5000 and 6 solar arrays with separate grid connected inverters of different brands, but was not measuring solar at all.
Last days i have reconfiguring my electrical cabinet and bought a victron p3v75 for net metering and using my et340 for 3 solar arrays who are present on separate breakers in this main cabinet.
This is about half of phase 1 and all panels from phase 3. This is on acIN
The panels connected to phase 2 and from my garage also on phase 1 are on AC-out1 and a bit harder to measure because of the distance and they are in separated locations from my house and not have a dedicated cable.
So the system is measuring about half of the 12000 wp grid connected.
Are there any benefits of measuring all panels?
Should i do the effort and investment to optimize any further or will the ess work as it is now?
The red arrow is pointing to ALL solar yield combined measured by homewizzard and the victron screen is showing the et340 values.
Or no one who could comment saw your post. I know i missed it.
Its not terribly clear what you want here?
I personally like to see all the data from the system. In you case you seem to not care.
To see the generation information, that would require energy meters on each ac pv inverter if you have no other way to harvest information from the AC PV. Or maybe a node red dashboard if the ac pv has information it sends out over mqtt or has an api maybe?
Some advantages of full monitoring are performance checks, cost/ benefit analysis.
For some systems it is necessary for zero feed in. Not even sure if that is a concern for you.
Because i measure everything with Homewizzard i have already all those data including the real generation and return on investment calculated with my hourly changing Dynamic price tariff.
When i was not measuring solar for Victron at all, i didnt saw any yellow solar bar in vrm and there was no charging when solar was coming in on DESS.
For now this looks like it is going to work as expected. The system charges when there is solar. Not all is perfectly measured by Victron but Homewizzard tells the whole story.
