6 FAQs about [Iec standards for solar inverters]
What types of inverters are covered by IEC 62109-1?
Inverters covered by this standard may be grid-interactive, stand-alone, or multiple mode inverters, may be supplied by single or multiple photovoltaic modules grouped in various array configurations, and may be intended for use in conjunction with batteries or other forms of energy storage. This standard must be used jointly with IEC 62109-1.
What requirements do inverters meet?
Depending on the applicability of the inverter, unique national and regional standards must be fulfilled, including: For the CE, UKCA, UKNI marking processes, the inverter must fulfil the following requirements: Safety requirements for Marking and self-declaration EMC requirements for Marking and self-declaration
What OVC level should a solar inverter be used for?
Unless specified otherwise, we use OVC III for grid-tied circuits and OVC II for PV circuits, and pollution degree 2 in this discussion. Also, this document only covers requirements for isolators versus other components in a solar inverter system, such as power modules and heat sinks.
What is the voltage requirement for a solar power conversion system?
For the example solar power conversion system, the AC phase-to-phase voltage is 480 VRMS, the DC link voltage is 1500 VDC, and the open circuit voltage of the PV panel is 848V DC. With the open circuit voltage of 848 VDC, the surge voltage requirement is determined to be 4000 VPK.
Do solar power conversion circuits need a basic isolation?
In the solar power conversion system (Figure 1), the isolated gate drivers and isolated voltage and current-feedback circuits both need to support reinforced isolation. Basic isolation is suficient if another basic isolation is inserted through the isolated data links.
What isolation options are available for solar power conversion applications?
In response to these needs, Texas Instruments offers several isolation offerings for solar power conversion applications. These include isolated IGBT gate drivers, digital isolators, isolated delta-sigma ADCs and amplifiers, and isolated communication links such as isolated RS-485 and isolated CAN.
