Introduction This introduction is not part of IEEE Std 937-2007, IEEE Recommended Practice for Installation and Maintenance of Lead-Acid Batteries for Photovoltaic (PV) Systems. This recommended practice provides design considerations and procedures for storage,

8、location, mounting, ventilation, assembly and maintenance of lead-acid secondary batteries for photovoltaic (PV) power systems. Safety precautions and instrumentation considerations are also included. While this document gives general recommended practices, battery manufacturers may provide specific

9、 instructions for battery installation and maintenance. While there are other IEEE standards that cover lead-acid battery installation and maintenance, they are generally designed for other types of applications, such as float-service or utility grid-tied applications. This document provides informa

10、tion for installation and maintenance of lead-acid batteries in PV applications that are generally characterized by non-grid connected, cycling service. These procedures also reflect consideration of the typically remote nature of PV applications. Notice to users Errata Errata, if any, for this and

IEEE Recommended Practice for Installation and Maintenance of Lead-Acid Batteries for Photovoltaic (PV) Systems 1. 1.11.22.Overview Scope This recommended practice provides design considerations and procedures for storage, location, mounting, ventilatio

27、n, assembly, and maintenance of lead-acid secondary batteries for photovoltaic (PV) power systems. Safety precautions and instrumentation considerations are also included. While this document gives general recommended practices, battery manufacturers may provide specific instructions for battery ins

28、tallation and maintenance. Purpose This recommended practice is meant to assist lead-acid battery users to properly store, install, and maintain lead-acid batteries used in PV systems. Definitions For the purposes of this recommended practice, the following terms and definitions apply. The Authorita

29、tive Dictionary of IEEE Standards B11should be referenced for terms not defined in this clause. 2.1 dry-charged cell: A cell that has been assembled without electrolyte, using plates that have been charged and dried, requiring only to be filled with electrolyte to become an active cell. The cells ar

30、e sealed by the manufacturer to prevent oxidation. Typically done for ease of shipping or storage or both. 1The numbers in brackets correspond to those of the Bibliography in Annex B. 1 Copyright 2007 IEEE. All rights reserved.

31、ance of Lead-Acid Batteries for Photovoltaic (PV) Systems 3. 3.1NOTE 1NOTE 2NOTE 33.2Precautions Batteries are potentially hazardous, and proper precautions must be observed in their handling and installation. This recommended practice does not purport to address all of the safety concerns associate

32、d with its use. It is the responsibility of the user of this recommended practice to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. These instructions assume a certain level of competence by the installer/user. Applicable

33、practices and codes contain relevant information and should be consulted for safe handling, installation, testing, and maintenance of batteries. Applicable state and local codes must be followed. Work on batteries shall only be performed by knowledgeable personnel with proper, safe tools and protect

34、ive equipment. Protective equipment The following safety equipment for handling of the battery and protection of personnel shall be available: a) Safety glasses with side shields, goggles, and face shield, as appropriate b) Acid-resistant gloves c) Protective aprons and safety shoes d) Portable or s

35、tationary water facilities for rinsing eyes and skin in case of contact with acid electrolyte e) Class C fire extinguisher f) An acid-neutralizing agent (e.g., bicarbonate of soda mixed with approximately 0.1 kg/L of water) to neutralize any acid spillage g) Adequately insulated tools h) Lifting dev

36、ices of adequate capacity, when required Some battery manufacturers do not recommend the use of CO2fire extinguishers due to the potential for thermal shock.2The removal and/or neutralization of an acid spill may result in production of a hazardous waste. The user should comply with appropriate gove

37、rnmental regulations. Battery personnel shall conform to local safety requirements. Procedures The following safety procedures shall be followed prior to and during installation: a) Use caution when working on batteries since they present a shock hazard. b) Prohibit smoking and open flame, and reduc

38、e the potential for arcing in the immediate vicinity of the battery. c) Provide adequate ventilation and follow the manufacturers recommendations during charging. d) Ensure unobstructed egress from the battery work area. e) Avoid the wearing of metallic objects, such as jewelry, while working on the

39、 battery. f) Ensure that the work area is suitably illuminated. 2Notes in text, tables, and figures of a standard are given for information only and do not contain requirements needed to implement this recommended practice. 2 Copyright 2007 IEEE.

40、ed Practice for Installation and Maintenance of Lead-Acid Batteries for Photovoltaic (PV) Systems g) Follow the manufacturers recommendations regarding cell orientation. h) Ensure that battery racks and/or cabinets are adequately supported, stable, and secure (see 5.3). i) Connect support structures

41、 to the electrical ground system in accordance with applicable codes. j) Inspect all flooring and lifting equipment for functional adequacy. k) Restrict all unauthorized personnel from the battery area. l) Keep the battery clear of all tools and other foreign objects. m) Avoid static buildup by havi

42、ng personnel contact an electrical ground periodically while working on batteries. n) The pressure relief valves shall not be removed without the battery manufacturers approval. o) Inspect and test instrumentation for safe working condition. 4.4.14.1.14.1.2Installation design criteria Considerations

43、 that should be included in the design of a PV battery installation depend upon the requirements, function, and size of the system of which the battery is a part. The following subclauses describe general criteria for all PV battery installations. Enclosure Batteries should be protected by means of

44、a suitable enclosure, which may vary from a box to a room. The enclosure should be clean, dry, and adequately ventilated, and it should provide and maintain protection against detrimental environmental conditions and electrical shorts. Location The following should be considered when deciding on the

45、 location of the battery enclosure: a) The battery enclosure should be located as close as practical to the PV array, loads, and power conditioning equipment. b) The enclosure location should provide adequate structural support. c) The battery location should be designed to eliminate the contaminati

46、on of water supplies and damage to equipment in the event of electrolyte spillage. Refer to IEEE P15783B9 for additional information. Mechanical considerations The following mechanical aspects should be considered during the design or selection of the battery enclosure: a) The size of enclosure shou

47、ld allow for sufficient clearance around the battery to provide access for installation and maintenance. Consideration should be given to the space required for safety and handling equipment (see 3.1). b) The supporting surface of the enclosure should have adequate structural strength and stability

48、(for high racks and cabinets) to support the battery weight and its support structure. 3Numbers preceded by P are IEEE authorized standards projects that were not approved by the IEEE-SA Standards Board at the time this publication went to press.
