Hi all
thank in advance for the help and advice...
I am in the process to upgrading my house bank to LiFePO4, installing 8 EVE 304ah cells, making a 12v 600ah system. While the starter battery will remain a lead acid 110 ah battery
Solar array:
- is it possible to charge the 2 banks with the single MPPT? or do I need to isolate the banks and feed only the house bank?
- if I isolate the house bank, then I should use a relay to cut the PV from the solar panels before disconnecting the charge relay, correct?
Alternator and AC to DC charger:
- as the alternator will be connected to both banks, do I still need to install a DC to DC charger or isolator?
I would think that once the LiFePO4 batteries are full, the BMS will disconnect the charge relay, but the alternator should continue feeding the the starter battery, no?
Or is it a matter of the alternator producing too much voltage?
-what Dc to DC charger would you recommend?
BMS:
- what recommendations?
The Tao BMS seems a pretty comprehensive system and allows interactions with external systems (e.g. water heater), and the X2 BMS has good reviews from the Ran Sailing channel.
Below my design, any thoughts? obvious errors?
Regards
Andres
