My system is currently as follows:
300 Watts Solar
Diesel Engine with 100amp alternator
Victron 100/20 mppt smart controller
Xantrex Freedom X 1000Watt inverter
3 x FLA house batteries
1 x FLA starter battery
Replacing the house batteries with 2 x 105 mah DYI batteries using EVE cells from Jenny Wu at Docan
From what I read so far I think I want/need:
1. Remove the Auto battery combiner and leave the starter FLA battery isolated
2. Add a dc to dc charger from the starter battery to the Lifep04 bank. Have alternator to starter battery only.
3. Add a victron smart shunt to lifep04 bank. Use the auxiliary on smart shunt for the starter battery voltage input
4. Add victron smart Battery sense to lifep04 for charge temp protection or is this redundant and covered by mppt controller or bms?
5. Run solar and shore power charging to lifep04 bank only
I have interior lighting, cell booster and a small fridge on the inverter. All the rest of the boat on 12vdc. Sail mostly weekends up to a week out at a time.
Does this seem like a reasonable way to power it with Lifep04?
Thanks for any advice
Cheers
