CCGX high battery voltage alarm

I just installed a 3 phase offgrid system with 3 multiplusses, a bmv 712, a mppt 150/75 and a CCGX. The battery voltage is configured at 48V. The real battery voltage is ca 52V. The Mppt gives a high battery voltage alarm on the CCGX. Wenn however the load (solarpanels) is disconnected, the voltage remains the same but there is no high battery voltage alarm coming anymore. Can anybody explain what is causing this problem?

Wie schon gesagt, wären ein paar mehr Infos nicht schlecht, z.B. welche Batterien im Einsatz sind.

Auch ein paar mehr Bilder u.a. von den Einstellungen im CCGX und ein paar Screenshots der Einstellungen im MPPT (VictronConnect App) könnten bei der Fehlersuche helfen.

Siehe anbei, recht herzlichen Dank fürs mitdenken. In der ccgx selber sind keine Einstellung geändert worden, ausser automatische Selektion vom batteriewächter (der BMV712).
