   - the house battery could get overcharged by higher voltages than lead-acid (lithium, for example)   - the house battery could get overcharged by higher voltages than lead-acid (lithium, for example)
   - 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

-If the device's own power source is disconnected it will turn off and 12v systems will be separate again.((again, latching relays excepted))  Using a High Voltage Disconnect to kill power to the device will stop the alternator from charging the house battery at a given voltage setpoint.+If the device's own power source is disconnected it will turn off and 12v systems will be separate again.((again, latching relays excepted))  Using a [[electrical:12v:hvd|High Voltage Disconnect]] to kill power to the device will stop the alternator from charging the house battery at a given voltage setpoint.
  
 Shutting down the device will require different approaches, depending on where it gets the power to operate itself. Shutting down the device will require different approaches, depending on where it gets the power to operate itself.
