Huasun’s Himalaya PLUS 760 HV series HJT module’s negative cell interconnection with a shorter creepage distance design and the use of butyl sealant, among others, are validated by the IEC 61215 certification
Its selection of construction materials or bill-of-materials and safety features are IEC 61730 certified
TÜV SÜD’s certificates will be valid for up to 5 years, until January 14, 2031
Heterojunction (HJT) manufacturer Huasun Energy recently launched the Himalaya PLUS 760 HV series module, which has been certified according to IEC 61215:2021 and IEC 61730:2023 standards by TÜV SÜD.
This module was developed primarily for a 2,000 V DC system voltage-level utility and desert-based projects. It consists 132 G12-size half-cut zero busbar (0BB) HJT cells in dual sub-string configurations, and measures 2,384 × 1,303 × 33 mm. The company states that the module’s active cell area covers up to 95.8% of the total size, attributable to its cell-to-cell overlapping design and a shorter creepage distance. It is the shortest insulation path between the cell matrix edge and the aluminum frames, which are prone to current leakage, says Huasun. It employs a butyl sealant for edge sealing between the glass and frames. According to the company, this PV material addresses the severity of DC electrical hazards compared to AC, and supports up to 33.3% higher DC system voltage of 2,000 V. It is a highly impermeable, non-hardening sealant that provides enhanced insulation against humidity and water ingress into the module. In addition to protecting against external environmental stressors, this sealing maintains compression and adhesion between glass and frame edges throughout the module’s lifecycle.
Of the 2 certifications mentioned at the start, the former validates the module’s design with the embedded bill of materials (BOM) for long-term environmental stresses. These BOMs are listed in the Constructional Data Form (CDF). Meanwhile, the latter justifies the usage and selection of construction materials while maintaining the required safety parameters. Given the shorter creepage distance, the critical parameters are insulation strength, leakage current, and grounding effectiveness at a system voltage up to 2,000 V DC.
In addition to this type-testing and safety certification, these modules are in mass production, with minor adjustments to the stringer machines.
