Hello,

In order to evaluate if there is an issue it is necessary to confirm if the MPPT haven't charged the batteries whilst there was excess of PV generation. And if that's the case please check in the history of the system (you can download this from VRM) what was the CCL at the time. This will tell you which of the devices decided no to charge the battery
