World’s largest true 3-phase microinverter installation powered by APS YC1000

The groundbreaking YC1000 microinverter from APS will power a milestone true 3-phase installation going into service in China’s Zhejiang Province this week.

More than 1.4 MW of the total 8.13 MW project will be generated using APS Microinverter technology – earning it distinction as the world’s largest true 3-phase microinverter installation.

The project at the Haining Hailide Jianshan factory began development four weeks ago, and is planned to join China’s national power grid on Dec. 30.

The installation includes 1,200 APS YC1000 microinverters. Now available in all APS markets worldwide, the YC1000 is the industry’s first true 3-phase microinverter and handles up to four modules per unit, simplifying PV system design and installation while significantly lowering balance of system costs.

The YC1000’s balanced 3-phase output features a low-voltage, parallel circuit design, promoting system safety by negating the possibility of “arc fires” from high-voltage current.

Independent output and tracking optimizes the performance of each PV module while minimizing shading effects across the whole array.

APS Microinverter technology increases array output by 5-25 percent compared to conventional “string” inverter systems.

Using the integrated APS Energy Communication Unit (ECU), Haining system managers will be able to track power output, voltage, current, temperature and other performance data of every module in the array.

The completed project will provide approximately 8.14 million kWh of energy per year, saving nearly 3,000 tons of coal while reducing CO2 admissions by more than 700 tons. Over the plant’s projected 25-year lifespan, the reduction in coal use and carbon and sulfur dioxide emissions will be multiplied many times over.

The year 2014 has marked the first widespread development of distributed PV power throughout China, an effort vigorously promoted by the Chinese government.

The electricity generated by the Haining system promises a strong economic return for investors, powering the factory even as it protects the local environment and promotes APS 3-phase microinverter technology in the robust China market and worldwide.
