Second Star has 2 150 watt Solar PV panels independently controlled by 2 Victron 75/15, the PV panels charge 2 Group 31 FireFly batteries. The controllers connect to a positive busbar.
Both controllers show the panels to be functional with open circuit voltages up to ~27 v.
Both controllers are on the same network.
One panel (port) is producing electricity and charging the battery, yesterday it developed 550wh with a max current output of 107 w.
The other panel (starboard) has no output with ~27 voc. This panel needs drops off the network every night and is not visible with the Victron Connect app until it is rebooted.
Both devices indicate they are configured for VE Smart Networking and "is waiting for data." With an additional message: "Sychronised charging is active and charge data is being shared between same type of chargers on the network."
At the moment, the batteries are at 68% SOC with the Port Panel supplying ~2 amps at 13.27 v to the battery. (It is 9:30 am, so low output would be expected.)
Open circuit voltage on the Starboard panel is 27.21v with no output.
The manuals and Victron website have not be particularly helpful.
What am I missing here? Why is only one panel supplying current, when both appear to be producing capable of supplying power?
Thanks for any insight and solutions.
