The new gui v2 is counting the amps wrongly causing the phase to change color from blue to orange and finally red.
In the attached screenshots I switched the display setup from Watts to Amps. This way the error count is obviously.
The low wattage on L1 is displayed correctly (69 W) in the last picture, however the display in amps is way off.
The wrongly counted amps are 2x the grid amps. Maybe a hint/clue?
If not an error, then please explain where are the 40+ Amps on L1?
Update 1 (thx Diessel): The color changes are dependent on the limit settings in Settings > General > Display&Appearance > Minimum and maximum gauge ranges. However I couldn’t find any documentation on this color function.
Update 2: The problem is caused by the P1 grid meter which doesn’t reverse the Amps when Wattage goes negative. See the first picture where 3967 W is delivered back to the grid and L1 shows 16 A. If I make this -16 A then the amps in the AC loads section is okay.
The solution can be either
Adjust the gridmeter to report negative amperage when the wattage is negative.
Venus OS gui2 should reverse the sign on the amps when the wattage is negative.
Update 3: Victron will not adjust their software to avoid erroneous results.
I solved my problem by reversing the amps when the wattage is negative.
Update 4: The EM24 has this problem with unsigned amps. With negative power it shows positive Amps.
System setup:
Venus v3.54 Cerbo GX
Grid connection 3x25A
single phase installation
Multiplus-II 48/5000/70-50 firmware 2623556
Battery 16x EVE MB31 with JK bms
What is the firmware version of MP2?
You have MP2 + Cerbo or MP2GX?
You updated only the Cerbo to 3.54?
More source data if you want to get useful answers.
UPD: Show a single line diagram of your installation and all equipment used.
Why is your VE.Bus MP2 configured for 3 phases?
You receive one phase from the Grid, and give one phase to the load, but from the screenshots above, your system is set to 3.
Doesn’t that bother you?
Off topic: the MP2 is configured for single phase and in the Settings > System setup > ESS > I set grid meter to “external” and multiphase regulation to “Total of all phases”.
On topic: I would like an explanation of the 40+ Amps reported in the display while the wattage in that same display is only 69 W.
See the last two screenshots in my first post. The screenshots are only seconds apart.
If back to the previous version of Venus, this error does not exist?
UPD: If I’m not mistaken, Victron previously wrote in the blog or here in the beta thread about problems & support with external meters with new Venus.
