HUAWEI - MERC-1100W-P Optimizer (Long Cable)

The MERC-1100/1300W-P is a 2-in-1 DC/DC optimizer that manages two Solar panels per unit. Each input accepts a module with an STC power rating of up to 1100 W (MERC-1100W-P) or 1300 W (MERC-1300W-P), with a tolerance of +10%. This 2-in-1 architecture reduces the number of optimizers to be installed per string and simplifies roof wiring.

The system operates using individual MPPT controllers for each pair of modules , with a voltage range of 12.5 to 105 V and a short-circuit current of 20 A. Maximum efficiency reaches 99.5% (EU standard 99.0%). The optimizer outputs up to 80 V and 22 A. Automatic bypass allows operation of a faulty optimizer without interrupting the string. In standby mode, the safety voltage is 1 V per controller.

The long cable version features a 1.3 m (+/-) input cable and a 0.1 m (+) and 2.9 m (-) output cable , facilitating connection to structures with significant module spacing. MC4 connectors. Dimensions: 149 x 104 x 49 mm, weight 1 kg including cables. IP68, -40 °C to +85 °C, 0-100% humidity. Mounting via mounting plate or T-bolt. Automatic recognition in less than 5 seconds. Integrated temperature detection and arc fault location.

Compatible with SUN2000-12-25K-MB0, SUN2000-12/15/17/20/23/25KTL-M5, SUN2000-30/36/40KTL-M3, SUN2000-50KTL-M3 and SUN2000-150K-MG0 inverters . Strings of 8 to 25 optimizers (20 max. on the 50KTL-M3 and SUN2000-150K-MG0), maximum power of 20,000 W per string.
