Cabin system running, but I have a few concerns

Q&A and troubleshooting

Have a read of this FAQ in the DIY section, linked from the FAQ sticky post at the top of DIY.

This explains why it jumps randomly and how to set your synchronisation voltage. The FAQ is based on 12V systems recommending setting the SmartShunt charged voltage 0.1 to 0.2V below absorption, fpr 48V something like 0.5V below would be a good starting point.

It often jumps if the charged voltage is set too low.

If you still get jumps then you need to slightly alter charged efficiency and/or Peukert coefficient.
