But in the settings , under inverter role , the postion of the Meter/PV inverter is on (terminal C) AC IN (as per the Actual Multiplus manual), but in the setting options in the Cerbo AC In is not listed see below
Which Dot do i have to choose to direct the info from the PV meter to the right Input ?
Although my Installation worked fine for the last 3 years. Every time my Soc drops under the VRM SOC, when the sun comes, it goes iton the grid instead of the battery. after Cold resetting the Multi and the cerbo the problem seem to rearrange it self , but after the next drop i hav to do a Cold restart.
my Multi’s and VRM also keep showing Low battary Alarm, and in the Cerbo panel it shows State : OFF
AC input 1 is the AC in of the multiplus. 2 is for quatro’s.
With the PV inverter on the AC in side of the inverter, it may help to have a grid current meter or CT, particularly if there are any loads on the input side.
Thanks,
but Looks a but stupid, as the Multi’s show connectors with AC-Out 1, AC Out 2 and AC in, and in the Cerbo it is only AC in1, AC in 2 and AC Out, which is the complete opposite, which only lead to confusion between the “soft position “ and the physical location of the connection.
The software automatically prioreties the AC out 1, but even so
My Shunt tells me 72 % ,
my VRM 's active SOC limit , yesterday dropped from 80 to 52 %,
i do not know what the Multi, has as %.
Earlier in the week when the sun was shining i went up to 90+ %, and therefore the active SOC limit must have fallen. resulting in a low battery, as the sun didn’t shine as predicted.
But still if the battery is not below 50%, it may be lower than expected . but should prioretise the Sun to battery instead of to the grid
