Huawei MERC-1100W-P - Smart power optimizer for PV modules
Huawei MERC-1100W-P is a smart power controller (Smart Module Controller) dedicated to photovoltaic installations with modules up to 1100 W. The device provides individual MPPT tracking for each module, maximizing energy yield even in partial shade. With safety features such as fast voltage shutdown down to 1 V and integration with Huawei FusionSolar systems, the optimizer guarantees high efficiency, safety and reliability in any PV installation.
- Maximum DC input power: 1100 W
- Input current up to 15 A - compatible with high-current modules
- Maximum efficiency of 99.5%
- Safe Shutdown function (1 V safe voltage)
- IP68 protection class and operating temperature range of -40°C to +85°C
Product description
Huawei MERC-1100W-P optimizer is a component of the modern PV system from the Smart PV Solution series. The device works with Huawei SUN2000 M2, M3 and M5 series inverters, enabling longer module chains and more flexible installation design. With individual MPPT, each PV module operates at the maximum possible power, regardless of the impact of shading or dirt on other panels. A fast mapping function (<5 seconds) and built-in thermal protection ensure reliable and safe expLoatation.
Safety and reliability
The MERC-1100W-P is equipped with emergency voltage shutdown (1V) and current anomaly detection, which significantly increases the level of fire safety. The IP68-rated housing provides full protection against dust and water, and the high conversion efficiency (99.5%) minimizes energy losses. The device, made of UV and corrosion-resistant materials, is suitable for use in extreme environmental conditions.
