I have a 12V deep cycle marine battery that is charged by a 20W solar panel. This works well. However I would like to use the battery to run two 120V 170mA 15W LED lights in a shed. So as I understand it, that means I need to connect an inverter to the battery to change the current from DC to AC. My issue is that I can only find inverters meant for cars which have wires (or alligator clips) to connect to the battery (fine) but then only output power to a receptacle. Something like this.
To connect this inverter to the light and a switch, I need wires. Since I can't seem to find an inverter that has output terminals I am wondering if plugging in a extension cord then cutting it to getting wires is advisable.
Am I understanding this wrong? Don't I need wires to power those lights. By my calculations I should be able to power those two lights easily. However I am very confused as to why I can't easily find an inverter that uses outputs wires. Are my terms incorrect? Does a lack of this product indicate my thinking in flawed?
Thanks in advance.
