Hi,
I have a boat. The starter battery is an old-fashioned lead. For all other purposes there are two agm batteries in parallel. The alternator loads the starter battery. The agms are loaded by the starter decoupled by diodes. When the boat has landline ac there is a cristec, that charges lead and agm.
I want to switch gradually to victron. I already bought a smartshunt, to get a deeper introspection into the agm and voltage of the starter battery. I bought the shunt with the display, that provides bluetooth. The next step is to add a solar-panel with a victron mppt 75. As I already have a display with bluetooth, how can I integrate the mppt 75 with the display, without adding another bluetooth device?
The steps following are:
2. Replace the Crestec Charger for a Victron (the crestec is not able to charge LiFePo4 in parallel to the lead)
3. Replace AGM against LiFePo4 and add a DC/DC Charger Orion 12/12 50 (the Alternator has 60A)
In the end, I want to see all the data in the app or maybe use other software (signalk/grafana) to display and analyze the data.
Do you have experience with a comparable setup and hints?
Thank you,
Alex
