- replaced the term "stand-alone lighting kits" with "stand-alone renewable energy products" throughout the document (including the title) to reflect that the revised document is applicable to a broader range of products with a more diverse set of capabilities.
- added test methods for flooded lead-acid batteries.
- significantly revised the protection tests, assessment of DC ports, appliance tests, and energy service calculations based on field experience.
- revised the voltage operating points at which testing is carried out to better reflect actual operation and to simplify the procedures for testing products without lights.
- revised the energy service calculations to include the effect of multiple simultaneously connected loads on the port voltage and battery-to-port efficiency and to accommodate products with grid or electromechanical charging.
