IEC TS 62257-9-5:20 18 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 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。

IEC TS 62257-9-5:2018 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

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.
