Huawei MERC-1300W-P Optimizer with long cable

Product description

The Huawei MERC-1300W-P Optimizer with long cable is an intelligent module that maximizes the output of each photovoltaic panel individually. With an input capacity of up to 1300 W, this model is designed for long strings or modules with split junction boxes, thanks to its extended cabling. Its high efficiency, IP68 protection, and rapid shutdown function make it ideal for demanding installations, especially in industrial or commercial environments.

Main features

• Nominal input power of 1300 W, ideal for large modules.
• High efficiency of 99.5 % with MPPT optimization per panel (12.5–105 V).
• Long negative output cable of 2.9 m, perfect for split junction boxes or long strings.
• IP68 protection, reliable operation in any environmental condition.
• Rapid shutdown (1 V) in case of fault or disconnection, complying with safety regulations.
• Module-level diagnostics for precise fault detection.

Advantages or benefits

• Improves overall system performance in installations with shading or uneven orientation.
• Allows flexibility in string design and reduction of BOS losses.
• Increases safety thanks to rapid shutdown per module.
• Simplifies maintenance with individualized monitoring.
• Compatible with very high-power modules (up to 1300 W).

Purpose or applications

The Huawei MERC-1300W-P with long cable is designed for commercial and industrial solar installations where module-level management is required, such as plants with partial shading, large roofs, or environments with rapid shutdown regulations. It is also ideal for systems with high-power modules and long strings, where extended cabling is essential.
