 +Scenarios with are less common than undervoltage but are more likely to cause damage to components.
 +
 +In a TV/motorhome an overvoltage in the DC vehicle system is likely associated with the failure of a voltage regulator.
 +
 +On the "house DC power" side high voltages are due to the necessarily-higher charging voltage being applied to the house batteries.  Trojan T-105 batteries, for example, are charged at 14.8v, floated at 13.2v, and equalized at 15.5v.((http://www.trojanbattery.com/BatteryMaintenance/Charging.aspx))  These voltages may trip safety circuits in some devices and it is common to disconnect house wiring before equalizing.  
 +
 +In smaller applications it may be possible to run [[http://amzn.to/2efAaDb|a DC-DC converter]] between the battery and the house wiring.  This would allow the battery to run at charging voltages but provide house power at 12.7v or whatever level you prefer.
