Hybrid Bi-direction Solar Inverter GS3.6 K

Hybrid Bi-direction Solar Inverter EA3.6 K

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.

Characteristics

Operating Flexibility
