Mayday! Controller goes berserk...

Hi,

I've just installed my 3 phase Multiplus 2 3000, but the system doesn't operate correctly.

Please take a look at the following youtube video to see what I mean. Around timestamp 3:17, after I change the inverter power limit, the controller goes berserk by alternately pushing energy into the grid and charging the battery. The AC load was constantly around 400 W.All the devices are on the latest firmware.

Suggestions about what might be wrong are much appreciated. Thank you.

Problem solved. I've made a support request to Victron and Victron dealer assigned to my hardware solved it.

The black connector for "Current sense" on one of the multipluses was not fully inserted into the socket. I've pushed it in and the system started to work correctly.

Hi, 3-phase systems are complex. If there is any hope of giving advice you will need to better detail the setup and configuration (and in good detail).

There really is not enough here to help.
