Product Description


Higher yields / Safe & Reliable / Smart / User-friendly
SUN 3/6K-SG04,hybrid inverter, is suitable for residential and light commercial use, maximizing self-consumption rate of solar energy and increasing your energy impendence. During the day, the PV system generates electricity which will be provided to the loads initially. Then, the excess energy will charge the battery via SUN 3/6K-SG04. Finally, the stored energy can be released when the loads require it. The battery can also be charged by the diesel generator to ensure uninterrupted supply in the event of grid blackout.
It equipped with RS485/CAN port for battery communication.
The New SUN-3K-SG04LP1 hybrid inverter adopts 24V battery, greatly improving your system safety.

Remotely shutdown function

Smart Monitoring Platform
Thanks to the smart monitoring platform, Deye full series inverter products support remotely shutdown immediately when accident occurs.Setting parameters and FW update remotely, which makes PV plant O&M easier.
