Have you heard of the compressor relay? Maybe you have heard about it but have no idea what it is or how it can help you. It is a piece of equipment that uses a small motor to drive a set of contacts that make electrical connections to a circuit board. It works in the following way. When an electrical appliance is plugged into the appliance port on your appliance box, an electric pulse passes through the circuit.
If the pulse that is created by the appliance has enough energy and can go through the compressor circuit, it will be controlled by the contact. When there is not enough energy for the electric pulse to go through the circuit of the relay contacts will turn on and shut off. The batteries will be partially charged and partially discharged. The battery on the compressor will be fully charged when the circuit is opened and the relay contacts are on. This will cause the battery to discharge and the entire electrical circuit will be closed again.
If the battery charge indicator is turned on when the contacts are off, then you are going to need to have the battery charged. There are a lot of different styles of compressor relays. You may want to check online to see if you can find one that will work for you. It could save you money and time to use one of these to help you with the power of the appliance.
