What size inverter do I need?

We do not recommend using a 120 volt AC to 12 volt DC inverter, due to the need of suppling the needed DC amperage that most inverters cannot supply.

Example:

The KW95122, 9,500 lbs. – 12 volt DC electric winch is designed for use with 12 volt DC power.  This is typically a 12 volt DC battery with a 650 CCA (cold cranking amp) capacity.  This winch has Motor Amp Draw requirements up into the mid-360 amp, depending on the line pull weight requirement, please see the 12V DC Performance chart below.

• Most user find it easier and cheaper to use a stand-alone 12 volt battery on the trailer, if the number of pulls are few and limited and recharge the battery with battery charger when returning back at home.  The battery could also be charged by running a 12 volt charging supply line with proper gage wire and circuit protector from the tow vehicle to the battery on the trailer.  This would recharge the trailer battery while driving the tow vehicle and trailer, this is also done by people towing a RV Camping trailers and how they keep their RV trailer battery charged.

• If you are going to need to perform multiple pulls on and off the trailer the recommended way to supply 12 volt DC power is to use the Keeper, KWA14607, 2 GA wire, 25’ Trailer Wiring Harness with “Quick Connects”.  This allow you to run 12 volt power from the tow vehicle’s battery back to the winch on the trailer and connect the wires using the “Quick Connects”.   This allows you to run the tow vehicle’s engine and also use the tow vehicles alternator to charge the tow vehicle battery while using the winch.
