Now Available! Specifically Designed for Microinverters

Since traditional centralized inverters and string inverters often have low efficiency and safety issues, microinverter technology emerged as the times require, and so did our AC connector.

In the process of energy storage systems converting DC power into AC power, these gadgets play a very important role, providing a continuous and stable current, and can convert and store electrical energy.

For different microinverter systems, Projoy provides different installation solutions.

The launch of PROJOY PECO series AC connector is simply another innovation and progress as PROJOY strives to provide users with more efficient and reliable solutions with the best technical solutions and services.
