GF series off-grid solar power inverter adopts Digital Intelligent Control and complete high frequency conversion topology, with high reliability and strong anti-interference. The rating input voltage is 24V/48V and rated power rating is 500W to 10KW. It is widely used in the solar power supply system such as communications, transportation, islands, border, rural, pastoral areas and so on.
Multi-setting:
PV priority mode or AC priority mode.
Choose the charging current based on the configured capacity of the battery.
High reliability: Double CPU digital control:
Independent MPPT (Maximum Power Point Tracking) control microprocessor system Independent inverter microprocessor control system
Isolated and pure sine wave technique:
LCD+LED display mode:
wide input range
high-speed synchronous conversion
The system can track the Mains phase automatically, and make sure the inverter output voltage is the completely same as the Mains voltage
Friendly alarm system
Unattended and intelligent monitoring：It can communicate with the PC by RS232 or USB interface，It also can realize remote monitoring, testing and regular shutdown/ starting-up operation by SNMP network system.
Online protection function
Intelligent No-load auto shutdown technology (optional)
