Good luck with
sale. I think your market will be limited to someone with quite old inverters etc.
I have a used one, have had no takers when advertised for reasonable
price. I had to upgrade to CCGX as the BPP required my Quattro inverter/charger to get a firmware
downgrade for it to
work with the BPP. I was not willing to do that, and this was about 5 years ago...
I could pair my BPP with a
Victron Battery Controller of the same vintage if anyone in my part of the world (Australia) is interested. They are good units, just not firmware compatible with
current model
Victron components.
