I'm considering connecting my lead acid starter battery (100 ah) to my agm house bank (400 ah) with a Victron Orion tr smart 12/30, charge the starter battery with the alternator (non regulated 60 amp Hitachi) and the house bank indirectly through the orion when engine battery is full.
- Is this an ok situation for the alternator?
- I have read that there is an efficiency loss from the orion. Is this bigger than the efficiency gain from having the alternator output regulated for agm batteries?
Thanks!
