Full Description

This part of IEC 62257, which is a Technical Specification, applies to stand-alone renewableenergy products having the following characteristics:

• All components required to provide basic energy services are sold and installed as a kit orintegrated into a single component, including at a minimum:
– A battery, batteries or other energy storage device(s)
– Power generating device, such as a solar panel, capable of charging the battery,batteries or other energy storage device(s)
– Cables, switches, wiring, connectors and protective devices sufficient to connect thepower generating device, power control unit(s) and energy storage device(s)
– Loads (optional), such as lighting, load adapter cables (e.g. for mobile devices), andappliances (television, radio, fan, etc.).

• The PV module maximum power point voltage and the working voltage of any othercomponents in the kit do not exceed 35 V. Exceptions are made for AC-to-DC convertersthat meet appropriate safety standards.

NOTE This voltage limit corresponds to the definition of decisive voltage classification A (DVC-A) for wet locations in Table 6 of IEC 62109-1:2010.

• The peak power rating of the PV module or other power generating device is less than orequal to 350 W.
• No design expertise is required to choose appropriate system components.

This document was written primarily for off-grid renewable energy products with batteries andPV modules with DC system voltages not exceeding 35 V and peak power ratings not exceeding350 W. The tests contained herein are capable in many cases of adequately assessing systemsat either higher voltages or power ratings, or both. In situations where the specifyingorganization agrees to apply these tests to products with higher voltages and power ratings,the test laboratory is responsible for ensuring that adequate safety measures are employed toprotect technicians and test equipment. The specifying organization is also responsible fordefining the consumer safety requirements of these products.

This document includes provisions related to safety; however, it is not intended to be acomprehensive safety standard. In particular, this document is not intended to be used as analternative to safety standards such as IEC 62368-1 or IEC 60335 (all parts) for appliancessuch as radios and televisions that are included with stand-alone renewable energy products.Nor is it intended to replace the safety requirements of IEC 62281 or UN 38.3 for battery safetyduring transport, or safety requirements of IEC 61730-1 and IEC 61730-2 for PV modulesintended for use outside the context of stand-alone renewable energy products.

This document does not address electromagnetic compatibility (EMC). Field experience has notshown EMC to be a major concern in typical applications of stand-alone renewable energyproducts within the scope of this document. In applications where EMC is a concern (e.g.systems that include medical devices), the standards relevant to the specific application shouldbe referenced.
