SUN-3K-SG04LP1-24-EU

Description

Higher yields / Safe & Reliable / Smart / User-friendly

SUN 3/6K-SG04, hybrid inverter, is suitable for residential and light commercial use, maximizing the self-consumption rate of solar energy and increasing your energy impedance.

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 is 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, SUN SMART  full series inverter products support remotely shutdown immediately when accident occurs. Setting parameters and FW update remotely, which makes PV plant O&M easier.

• Colorful touch LCD, IP65 protection degree
• 6 time periods for battery charging/discharging
• Max. charging/discharging current of 120A
• Max.16pcs parallel
• DC couple and AC couple to retrofit existing solar system
• Support storing energy from diesel generator
• 24/48V low voltage battery, safe and reliable
• Unique Smart Load application and Grid peak shaving function
• 4ms fast transfer from on-grid to off-grid mode, ensuing the traditional fixed frequency air conditioner works well
