The DC/AC Inverter ground input shall be dedicated to the vehicle battery and rated for 20A for 150W
and 43A for 400W.
DC/ Inverter is used to convert 12 Volts supplied by the DC vehicle battery to an AC output voltage of
120V AC RMS / 60Hz (NAFTA Market) with a peak power rating 400 Watts for customer use. Such
DC/AC Inverters are intended to power user loads of convenience type small appliances.
OEM factory inverters use a modified sine wave and medically sensitive devices typically work with
full sine wave; use of medical equipment is not recommended.
Note: Operating any inverter at its max rating is usually ok for a short period but can heat the
inverter up and cause a reset. “The power inverter is designed with built-in overload protection. If the
power rating of 150 Watts is exceeded, the power inverter automatically shuts down. Once the
electrical device has been removed from the outlet, the inverter should automatically reset. If the
power rating exceeds approximately 170 Watts, the power inverter may have to be reset manually."
To reset manually, cycle the ignition off, complete a vehicle sleep cycle (door open) and then closed.
