IEEE Revises Two Lead-Acid Battery Standards For Photovoltaic Systems

Piscataway, NJ - IEEE has revised two standards for the installation, maintenance and sizing of lead-acid batteries in photovoltaic systems. The first standard, IEEE 937™, "Recommended Practice for Installation and Maintenance of Lead-Acid Batteries for Photovoltaic (PV) Systems", was updated to reflect changes in installation and maintenance practices and in related standards. IEEE 937 addresses such considerations as the storage, location, mounting, ventilation, assembly, safety and care of lead-acid batteries in residential, commercial, and industrial PV power systems. It was developed for use by system designers, installers and owners.

The second standard is IEEE 1013™, "Recommended Practice for Sizing Lead-Acid Batteries for Stand-Alone Photovoltaic (PV) Systems", which was revised to make it specific to stand-alone PV systems and to add changes reflecting field experience. This standard helps system designers analyze how design-parameter changes affect the size of vented and valve-regulated lead-acid batteries in PV power systems. It allows them to strike an acceptable compromise between cost and performance. These standards are sponsored by Standards Coordinating Committee 21 for Fuel Cells, Photovoltaics, Dispersed Generation, and Energy Storage.
