The hybrid PowerBuoy provides its power from the lithium-iron phosphate batteries located on board. These batteries are primarily charged by the solar panels also located on the hybrid PowerBuoy. In situations where the solar panels are not able to provide enough power to charge the batteries, then the backup battery will switch in to provide less eco-friendly power to keep the hybrid PowerBuoy as an Uninterruptable power supply. The batteries are connected to a cable that transfers the power to the payload.
