Darfon

G640 Microinverter

Model Number: G640-208, G640-220, G640-240, G640-277
With the benefits of a microinverter and cost-per-watt of a string inverter, the Darfon G640 is the most economical solution for residential and commercial systems. It is a dual-input microinverter with just one AC connector and can be used with standard tree or daisy chain cables. The G640 also features a redundancy capacitor design that continues working even if the electrolytic capacitors have problems over time.
