Inexpensive DIY Under-Cabinet Lighting

Step 3 Connecting it all Together

1. You will want your inverters to be wired in parallel. I soldered all of my connections for added durability and to lessen resistance. Your connections don't have to be beautiful. This is a simple job of connecting wires.

2. Unless your lights are going to be very close together, you will want to use additional lengths of wire to connect to your power supply to each inverter. I ran a single line of 2-conductor appliance wire around the kitchen and cut into it periodically to splice into.

3. Connect the wire coming from your power supply's ground to the ground on all of the inverters. Connect the positive wire to the switched positive wire. See the diagram below for more information.

4. Be sure to properly insulate all ground and positive wires from touching and secure all connections so they are tight. You can use the multimeter to check your wiring at this point and then give it a test.

5. If things do not immediately light, turn it off quickly and unplug everything. Begin to troubleshoot. Visually inspect connections, use your multimeter to find problems, and input extra stuff to narrow down the problem.

6. If all is well, move on to mounting the lights in the next step.

A nice simple project that anyone can build! Good idea! If you want to save power though, the switch should be on the power lead to the transformer rather than after it, because even though you switch the power off you will still be consuming power in the power supply transformer windings.
