Hello,
looking for some guidance with my 400ah lithium upgrade from my current 420ah AGM bank.
I have 400 watts of solar and will swap out my existing Xantrex C35 with the Victron 30a smart MPPT (may be able to change the Xantrex to meet the LIFEPO4 charge parameter, but not interested in keeping it).
I also plan to do a 40 amp DC to DC charger to protect the 80 amp alternator. Looking at the Victron Orion product.
My AC/shore power 40a charger and 3000 watt inverter do not need to be upgraded and I will keep them for now.
Also, I currently have a 500a shunt that came with my Victron BMV-700 monitor fully installed.
questions:
1) see any issues with this approach?
2) Should I look at upgrading the BMV to the 712? Not sure what this upgrade may give me via Bluetooth that the smart controller or Orion would not.
Goal is to swap out charger/inverter if/when one of the existing devices fail, but no need to spend the money now.
