Hybrid (Bi-direction) Solar Inverter EA3KHD

Hybrid (Bi-direction) Solar Inverter is PV energy combined with energy storage systems. It utilizes solar power, AC utility and battery power to ensure continuous power supply, and users can store the unused energy produced during the day by PV system in the battery and use it whenever they needs, even at night, it helps increase self-consumption and achieve greater energy self-sufficiency.

Hybrid (Bi-direction) Solar Inverter EA3KHD

Operating Flexibility

Operating modes can be programmed flexibly

On-grid operating, easy feed-in to the grid, backflow prevention, energy self-generation and self-consumption.
