Off-Grid Inverter

GF1-3K5/4K5/6K2S3

The GF1 series is a single-phase off-grid solar inverter designed for backup power, energy storage, and uninterrupted electricity. It features a high-efficiency MPPT charge controller, supports parallel operation for three-phase output, and offers flexible battery compatibility. The compact design includes a removable dust filter and enables real-time monitoring via dual communication interfaces and a mobile app.

Datasheet
