Abstract
The present disclosure provides a programmable controller for monitoring battery performance and usage at a remote pump jack location. The disclosure provides an energy efficient controller and display system which allows the operator to quickly and accurately test batteries in an installation. It uses programmable logic to switch between system modes and decide which battery supplies power to the output. Further it will sense any high voltages at and disable the input from the faulty source. Further, the programmable logic is designed such that the mode selection process is automatic when the system is in operation. The purpose is to elongate battery and connected equipment life by preventing battery failure. The present disclosure also provides an easy and economical method of communicating potential battery failure and status to an operator via cell phone communication.
