标准摘要
[中文适用范围]： 本部分IEC 62257是一项技术规范，规定了适用于不同离网应用的逆变器选择和尺寸标准，这些应用将太阳能作为能源。 除了离网系统外，本文件还适用于逆变器，其中公用事业电网连接可用作电池充电的备用电源，但不旨在涵盖逆变器同步并将能量注入公用事业电网的应用，即使此功能可能是逆变器功能的一部分。 包括单相和多相应用。 [外文原描述]： IEC TS 62257-9-7:2019 specifies the criteria for selecting and sizing inverters suitable for different off-grid applications integrating solar as an energy source. As well as off-grid system, this document can also apply to inverters where a utility grid connection is available as a backup for charging batteries, but it is not intended to cover applications in which inverters synchronize and inject energy back into a utility grid, even though this capability may incidentally be a part of the functionality of the inverters. Single and multi-phase applications are included.
