Lithium Ion System problems

I realized this post was in the wrong forum.

Could use some assistance from the community. I recently installed a complete Victron Lithium Ion system including the following items.

Victron Isolation Transformer.
Lynx Ion Internal shunt 600A
Quattro 24/3000
Color Control GX
2 each Lithium Ion Batteries 24/3000w/70-50/70

As you can tell this was a very expensive system that was promised to be both well developed and functionally superior to other systems on the market. Again let me stress this was not a piece purchase, do it yourself affair but a system purchase from a certified installer in the Netherlands.

The system has been plagued with system malfunctions relating to its ability to continually charge which has manifested first with a bad Shunt and later with transient drop outs of the charger causing the system to run the batteries down to the point they switch off requiring a restart.

Has anyone else dealt with these components and had similar problems and most importantly has anyone had any success fixing these problems. Thanks for any help you might be able to give.

Re: Lithium Ion System problems

My first impression is a possible intermittent DC connection, tricking the charger to think batteries are full. Either that, or an intermittent AC connection to the charger.
Both scenarios could cause your symptoms.

Carefully check EVERY connection for proper assembly, especially crimps for wire pulling out. That's why I solder all mine.

Re: Lithium Ion System problems

What does the supplier suggest? It's difficult to suggest a starting point with the limited info you provide.

You mention the system ran the batteries down. How are you monitoring state of charge? How have you configured the controller. Are all connections functioning properly? Can you provide a schematic? What loads do you have on the system?
