The Importance of Compliance and Durability in PV Hybrid Inverters: A Look at Sungrow’s SC Series

Photovoltaic (PV) hybrid inverters are critical components in solar energy systems, interfacing between solar panels, battery storage, and the electrical grid. The reliability, safety, and efficiency of these systems are significantly enhanced by adhering to international standards and certifications. In this blog, we’ll explore the significance of CE marking, IEC 62477, and IEC 61000 standards in PV hybrid inverters and introduce Sungrow’s SC series inverters, which exemplify compliance and adaptability in challenging environments.

Understanding CE, IEC 62477, and IEC 61000 Standards

CE Marking

The CE marking is a declaration by the manufacturer that their product complies with all applicable European safety, health, and environmental protection legislation. For PV hybrid inverters, this means they meet the EU requirements for safety and can be freely traded within the European market. This marking is crucial for manufacturers to demonstrate compliance and ensure customer trust and product acceptance in Europe.

IEC 62477

IEC 62477 is a safety standard specifically focused on power electronic converter systems and equipment. For PV hybrid inverters, compliance with IEC 62477 ensures that they are designed and built to handle electrical, thermal, and mechanical stresses safely. This standard covers aspects such as insulation requirements and the prevention of electrical shocks and fires, which are critical in high-voltage electrical equipment.

IEC 61000

IEC 61000 deals with the electromagnetic compatibility (EMC) of electronic devices. Compliance with this standard ensures that the inverter does not emit excessive electromagnetic interference (EMI) and is also resistant to EMI from external sources. This is crucial in maintaining the functionality of the inverter and nearby electronic devices, preventing disruptions and malfunctions in both the inverter and other equipment in its vicinity.

Introducing Sungrow’s SC Series: Compliance and Corrosion Resistance

Sungrow‘s SC series inverters, including models like the SC2750UD-MV, SC3150UD-MV, SC3450UD-MV, SC4000UD-MV, and SC5000UD-MV, stand out not only for their advanced technical capabilities but also for their compliance with critical international standards:

– Compliant with CE, IEC 62477, IEC 61000: These certifications assure users that Sungrow’s inverters meet high standards for safety, reliability, and electromagnetic compatibility, making them suitable for a wide range of installations, including residential, commercial, and industrial applications.

– Optional C5 Anti-Corrosion Degree: This feature is especially important for installations near maritime environments. The C5 anti-corrosion classification implies that the inverter is protected against salt mist and other corrosive elements, which are common in coastal areas. This protection enhances the durability and longevity of the inverter, ensuring continued performance in conditions that might otherwise accelerate wear and degradation.
