 This is the simplest and cheapest option, but requires ingenuity to keep boosted voltage from leaking back to the chassis.  In this case the isolator (solenoid) is turned off by the HVD at Vfloat (conservative) or just below alternator voltage (power-maximizing). This is the simplest and cheapest option, but requires ingenuity to keep boosted voltage from leaking back to the chassis.  In this case the isolator (solenoid) is turned off by the HVD at Vfloat (conservative) or just below alternator voltage (power-maximizing).
