It seems that many builders load the Endurance Bus with more than absolutely necessary. If the combined loads on E-Bus total 10 amps or more, is it really necessary to have over-voltage protection for the SD-8? The permanent magnet dynamo might have trouble maintaining 14 volts, let alone putting out 15 or 16 or higher voltage. And even if the voltage were above normal, the battery should be able to absorb the extra current for a longer time period than it could if the main alternator was putting out too high voltage.
Modern avionics are made to handle up to 30 volts. But if a Lithium battery is installed, over-voltage protection is important.
Some pilots might leave the aux alternator turned on during normal flight. In that case, an over voltage condition will trip both over-voltage modules simultaneously.
