I have a 3 phase system, made up of 3 x Multiplus 48/3000/35. The system will not output or charge battery. The Mains and Float LEDs flash simultaneously.
I've checked the system configured the system using VE.Bus Config.
It is switched as a group. and each individual device shows no error when checked.
There is a mains 3 phase supply present at the inputs which has the correct phase rotation.
There is a 48 volt battery on the DC.
Wiring has been checked point to point, and this all rings through correctly.
What is the error being displayed? And how can it be rectified?
