IEEE 1661-2007

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 batterya??s operating set points 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.
