新的！IEC TS 62257-9-5:20 18作为IEC TS 62257-9-5:20 18 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC TS 62257-9-5:20 18适用于独立的可再生能源产品。本文件主要涉及直流系统电压不超过35 V、峰值额定功率不超过350 W的电池和太阳能组件的离网可再生能源产品。本文所包含的测试在许多情况下能够充分评估处于较高电压和/或额定功率的系统。与上一版相比，此新版本包括以下重大技术变更:-在整个文件（包括标题）中将术语“独立照明套件”替换为“独立可再生能源产品”，以反映修订后的文件适用于具有更多样化功能的更广泛的产品。-增加了淹没式铅酸蓄电池的试验方法。-根据现场经验对保护测试、直流端口评估、电器测试和能源服务计算进行了重大修订。-修订了进行测试的电压工作点，以更好地反映实际操作情况，并简化测试无灯产品的程序。-修订了能源服务计算，以包括多个同时连接的负载对端口电压和电池到端口效率的影响，并适应具有电网或机电充电的产品。

NEW!IEC TS 62257-9-5:2018 is available as IEC TS 62257-9-5:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC TS 62257-9-5:2018 applies to stand-alone renewable energy products. This document deals essentially with off-grid renewable energy products with batteries and solar modules with DC system voltages not exceeding 35 V and peak power ratings not exceeding 350 W. The tests contained herein are capable in many cases of adequately assessing systems at higher voltages and/or power ratings. This new edition includes the following significant technical changes with respect to the previous edition:
- 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.
