Huawei MERC-1300W-P Smart Module Controller Optimizer

The Huawei MERC-1300W-P is a smart module-level power optimizer designed for use with Huawei SUN2000 series inverters. It delivers module-level optimization to increase system energy yield by 5% to 30%, with maximum efficiency of 99.5% and weighted efficiency of 99.0%.

The optimizer features active safety with safe voltage shutdown (1 V when disconnected or inverter off), pinpointing open-circuit fault detection for quick troubleshooting, and a long string design to reduce balance-of-system costs. It operates across an MPPT voltage range of 12.5–105 V with a maximum output of 80 V at 22 A.

Installation is quick and simple with a single screw mount. The device is IP68-rated and operates reliably from –40°C to +85°C. Each PV module under the same inverter must be equipped with a MERC optimizer for full optimizer configuration.
