Abstract :
A new valve regulated lead-acid (VRLA) gel motive power battery and PV system power center have been tested in the laboratory and at a PV hybrid telecommunication site. The power center provides battery charge control, system remote communications, and data acquisition at the field test site. Extensive laboratory and field-test data were used to improve battery performance by optimizing regulation voltages, finish-charge, and system design. After 1.5-years of service, battery and charge controller performance have met all performance requirements for the remote communications site at Sandia National Laboratories
