          This guide is specifically prepared for a PV/engine generator hybrid power system, but may also be applicable to all hybrid power systems where there is at least one renewable power source, such as PV, and a dispatchable power source, such as an engine generator. Taper-charge parameters for PV hybrid systems are suggested to help in preparing the battery for a capacity test. A test procedure is provided to ensure appropriate data acquisition, battery characterization, and capacity measurements. Finally, a process to review test results and make appropriate decisions regarding the battery is provided. No cycle-life predictions are made.<br />\n

          This guide contains a field test procedure for lead-acid batteries used in PV hybrid power systems. Battery charging parameters are discussed with respect to PV hybrid power systems. The field test procedure is intended to verify the battery’s operating setpoints and battery performance. Discussion on how to interpret test results is also included. This guide is applicable to all stand-alone PV hybrid power systems where PV and an engine generator are the only charging sources. This guide does not include stand-alone PV-only systems.<br />\n
          This guide was written to provide a photovoltaic (PV) hybrid power system battery test procedure that can be used to assist in evaluating battery capacity, and appropriate PV battery charging requirements. Use of this guide by funding organizations, battery manufacturers, PV system integrators, and consumers should provide the means to assist in identifying systems that may benefit from improved system design and its subsequent charging specifications.

          This guide is specifically prepared for a PV/engine generator hybrid power system, but may also be applicable to all hybrid power systems where there is at least one renewable power source, such as PV, and a dispatchable power source, such as an engine generator. Taper-charge parameters for PV hybrid systems are suggested to help in preparing the battery for a capacity test. A test procedure is provided to ensure appropriate data acquisition, battery characterization, and capacity measurements. Finally, a process to review test results and make appropriate decisions regarding the battery is provided. No cycle-life predictions are made.<br />\n

          This guide contains a field test procedure for lead-acid batteries used in PV hybrid power systems. Battery charging parameters are discussed with respect to PV hybrid power systems. The field test procedure is intended to verify the battery’s operating setpoints and battery performance. Discussion on how to interpret test results is also included. This guide is applicable to all stand-alone PV hybrid power systems where PV and an engine generator are the only charging sources. This guide does not include stand-alone PV-only systems.<br />\n
          This guide was written to provide a photovoltaic (PV) hybrid power system battery test procedure that can be used to assist in evaluating battery capacity, and appropriate PV battery charging requirements. Use of this guide by funding organizations, battery manufacturers, PV system integrators, and consumers should provide the means to assist in identifying systems that may benefit from improved system design and its subsequent charging specifications.

This guide is applicable to all stand-alone PV hybrid power systems where PV and an engine generator are the only charging sources. This guide does not include stand-alone PV-only systems.<br />\n

Use of this guide by funding organizations, battery manufacturers, PV system integrators, and consumers should provide the means to assist in identifying systems that may benefit from improved system design and its subsequent charging specifications.
