 There are scenarios where one might want to prevent a [[electrical:12v:alternator|battery isolator]] from combining the house and chassis 12v systems: There are scenarios where one might want to prevent a [[electrical:12v:alternator|battery isolator]] from combining the house and chassis 12v systems:
  
-  - the house battery could get overcharged by higher voltages than lead-acid (lithium, for example)+  - the house battery might be a chemistry that could get overcharged by the alternator (lithium, for example
 +  - the house battery might have a resting voltage high enough to trigger the house side of a dual-sensing relay (LiFePO4)
   - the combined circuit can feed higher-than-optimal voltages back from solar charge controller to the chassis' electronics.   - the combined circuit can feed higher-than-optimal voltages back from solar charge controller to the chassis' electronics.
   - a [[electrical:12v:b2b|b2b charger]] in parallel with an [[electrical:12v:alternator|isolator]] could have the same backfeeding result   - a [[electrical:12v:b2b|b2b charger]] in parallel with an [[electrical:12v:alternator|isolator]] could have the same backfeeding result
