Solar battery wireless load cell adapter

An adapter for a load cell in a rod pump system, the rod pump system having a rod clamp fixed to a top of a vertical polished rod and a clamping bar fixed to a hanger harness attached to a horsehead, the load cell on the polished rod between the clamping bar and the rod clamp, the adapter comprising:

• an outer shell including a mounting portion configured to attach to the load cell;
• a power supply configured to provide power to the adapter and the load cell, the power supply including a solar panel on the outer shell;
• a cable configured to connect to the load cell,
• wherein the cable is external to both the load cell and the outer shell of the adapter,
• wherein the adapter is configured to provide power to the load cell via the cable, and
• the adapter is configured to receive a load signal from the load cell via the cable;
• a signal processor configured to receive and process the load signal and to output load signal data representative of a load experienced by the load cell;
• and
• a wireless transmitter to transmit the load signal data,
• wherein the adapter is external to the load cell,
• wherein the mounting portion is on a side of the outer shell opposite to that of the solar panel, the mounting portion including two elongated openings and a horizontal flat panel configured to fasten directly to and flush with a horizontal platform of the load cell with bolts, the horizontal platform being a protrusion of the load cell,
• wherein the solar panel faces outwardly from the load cell on the polished rod.
