How to Wire a Power Inverter

What You'll Need
2-Guage Wire
175 Amp Plug
Impedance Wire
Welding Cable
Lug Crimper
Shrink Tube
A Knife
Heat Gun

A power inverter is simply an electrical device that converts direct current, or DC, to alternating current, or AC. In simple words, an inverter is used to provide alternating current (AC) from the direct current sources (i.e., batteries and so on). An inverter can be used to operate electronic devices such as kitchen appliances, TVs, computers, power tools and so on. In a simple fashion, an inverter is connected to the battery and the electrical appliance is plugged to the inverter.

Step 1 - Begin Plan

For instance, let us say we want to wire a 1000-watt power inverter. Plan to use a 2-gauge wire that is no more than 5 feet in length. Also make available a 175 ampplug.  An impedance wire to run from the battery will also be needed plus a welding cable. Other things that would be needed include a lug crimper and a shrink tube.

Step 2 - Start Cutting

Cut a hole in the rubber flashing close to the radiator and fixed the 1/0 wire via the flashing and grill. At the engine compartment, pull the wire round to the battery region. Guess how much installation can conveniently be removed from the cable. Check the depth of the lug and set it close to the cable. Remove the insulation; fix the wire, and lug in the crimper. Use the two layers of shrink tube to insulate the lug. Use a heat gun to shrink the tube and put the shorter of the two pieces on the first.

Step 3 - Installation

To install the wires, screw down plug to the car bumper and arrange the cable for the power inverter. Plug the positive and negative plugs properly (i.e., positive to plus sign and negative to minus sign).

Step 4 - Keep the Contacts Clean

There is need to keep the terminals clean to allow for proper flow of electricity current. Check to make sure that all connecting wires have no debris. If there are, use a small brush or wire stripper to remove any unwanted residue.

Step 5 - Battery Configuration

In series connection the capacity doesn’t increase due to the addition of more batteries. Addition of more batteries in parallel battery wiring increases the run time of the arrangement. Series-parallel battery wiring increases the voltage output (ie, the more the batteries, the more the voltage). The battery configuration that you chose must depend on the required effect or the aim of wiring the power inverter.

The various wiring configurations are the series, parallel and semi-parallel battery configurations. In series connection the batteries are arranged in series with a positive terminal of one battery connected to a negative terminal of the other. The batteries are arranged in parallel with a negative terminal of one battery connected to negative terminal of a different battery. Same thing goes for all the positive terminals. The batteries are arranged in parallel with a negative terminal of one battery connected to negative terminal of a different battery. The series-parallel battery connection is a combination of the series and parallel configurations.

External Connections of the Inverter

Backside of the inverter has three connections. The first is the AC mains lead which is connected to the socket on the wall. The second connection has two HT-2 connections which are provided to connect the battery to the inverter. Red connector is connected to the positive terminal of the battery.
