Victron 100/20 MPPT with Starter Battery Maintainer

Q&A and troubleshooting

Afternoon all,

Just want to get some feedback and make sure I have got this right.

I am looking to change my current NDS MPPT for a Victron 100/20. Part of the reason for me choosing this model is to utilise the load connection and be able to monitor the battery maintainer.

I want to check if I have this right as to how I am setting this up,

Leisure battery connected to Victron Battery + and -
Solar connected to Victron PV + and -

Now the load connections to the battery master or similar (Sterling) - not decided which yet.

Red wire to + on Victron load
Black wire to - on Victron load
Brown wire connects to starter battery.

There is an existing wire from the starter battery connected through the Nordelettronica NE350 fuse board to the NDS MPPT, this is what I plan to use.

Thanks
Mark

That all sounds right and as the NDS system worked the starter and domestic batteries must already have a common negative or ground.
