Huawei MERC-1300W-P - Smart photovoltaic module controller
Huawei MERC-1300W-P is a smart power optimizer (Smart Module Controller) dedicated to commercial and industrial (C&I) installations. The device allows precise maximum power point tracking (MPPT) for each PV module, increasing the efficiency and safety of the system. It is designed to work with Huawei's SUN2000 series inverters, enabling long connection chains (Long String Design) and simplified installation.
- Maximum DC input power: 1300 W
- Input current up to 20 A - compatible with high-current modules
- Automatic module mapping in less than 5 seconds
- Quick shutdown function - 1 V safety voltage
- Advanced arc detection and localization (AFCI pinpoint)
Product Description
The MERC-1300W-P Smart Module Controller is a next-generation device that integrates power optimization, protection and intelligent monitoring functions. With individual MPPT for each module and the ability to operate at up to 20 A, the optimizer is compatible with modern high-power photovoltaic modules. The device provides fast mapping (<5 s) and intelligent temperature detection, which increases the safety of expLoatation. Thanks to the 1 V Safe Shutdown function, the system can be safely serviced and maintained even in high sunlight.
Safety and reliability
The Huawei MERC-1300W-P is equipped with an automatic DC voltage shutdown function (1 V per optimizer), which ensures maximum safety during service work. The device meets the requirements of IEC62109-1 (safety class II) and has an IP68 protection class, which guarantees complete resistance to dust and immersion in water. The temperature operating range of -40°C to +85°C allows installation in demanding environmental conditions.
