I’m commissioning my system composed of a multiplus 48/800/9, a LiIon battery (voltage range between 52 and 66V) and a Venus GX to configure and control my system.

How can I tune my absorption voltage ? (I read with Remote control on LAN).

I have also an issue:

Connected to the AC IN it works fine:

But when I remove (open) the AC IN an alarm arrives: and I have these notifications:

Can someone help me (what I did bad);

Previously it was working fine. i fear i changed a parameter somewhere…?

I personally would not switch on the mains as long as i have not confirmed the charging settings. Also commissioning of a new system for me includes updating everything to the latest firmwares.

You have low battery voltage alarms, so whatever you set as the alarm threshold was reached. You can change the charging voltages through VE.config, charger section, and the low alarm/shutdown in the inverter section. You can either do that through VRM, which i personally prefer, or by using an Mk3 dongle
