IEC TS 62257-9-5:2016

Recommendations for renewable energy and hybrid systems for rural electrification - Part 9-5: Integrated systems - Selection of stand-alone lighting kits for rural electrification

IEC TS 62257-9-5:2016(E) applies to stand-alone rechargeable electric lighting appliances or kits that can be installed by a typical user without employing a technician. It presents a quality assurance framework that includes product specifications, test methods, and standardized specification sheets. This new edition includes the following significant technical changes with respect to the previous edition:
- battery test methods updated to harmonize with existing IEC standards, sequence of testing changed to allow the battery to be charged using the product's charge controller prior to the full-battery run time test;
- limits on total series resistance of the test apparatus added to test procedures.
