scope:

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 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.

Purpose

 This guide provides a field test and evaluation procedure for lead-acid batteries used in PV hybrid power systems. It is intended to help system owners, designers, and funding organizations to select, manage, and verify lead-acid battery performance in PV hybrid power systems.
