Description

The new IQ8H-240-72-2-US microinverter, the highest power IQ8 model, is designed for high-power 60, 66, and 72-cell modules. These are the industry’s first microgrid-forming, software defined microinverters with split-phase power conversion capability to convert DC power to AC power efficiently. The leading microinverter brand due to advanced technology, features, and warranty. The 1:1 configuration with your solar modules means maximum performance energy yield & system reliability in any conditions.

The brain of this advanced semiconductor-based microinverter is Enphase’s proprietary application-specific integrated circuit (ASIC) which enables the microinverter to operate in grid-tied or off-grid modes. This chip is built in advanced 55nm technology with high speed digital logic and has super-fast response times to changing loads and grid events, alleviating constraints on battery sizing for home energy systems.
