GF Series Off-grid Solar Inverter
Capacity Range: 100W-2400W
No matter what you are suffered, either an unreliable grid or no grid at all, GF Series off-grid solar inverter can solve the problems by supporting various household appliance with a reliable electricity supply. Since the sun power is not always sufficiently available to cover the energy demand, you want more power sources, like Generator Set, Grid and even Wind power, and then use battery for backup using at night or whenever there is a power problem. With GF Series inverter, you can manage all these function into a complete solar system.
Note:
Ground Connection
Add air switch (breaker) between inverter and battery while installation
Optional Functions:
1. No load inverter off and automatically on when load comes
2. Communication Interface for monitor purpose: RS232, USB, SNMP
3. Control to start the Generator
FEATURES:
LCD+LED display;
Self-adaptive Frequency: 50Hz/60Hz;
Friendly Alarm System;
Multi-setting:
PV priority or AC priority working mode;
Battery charging current selectable (5A-20A, 10A-60A)
Wide Input Range:
MPPT control system adopts PWM adjustment technology which can bear the highest open circuit voltage of the PV battery;
The product AC input equipped with high effective online synchronous voltage regulation technology, input from165-275Vac operating with safety,greatly decrease the battery use frequency and extend the battery service life
High Reliability:
Independent MPPT (Maximum Power Point Tracking) control microprocessor system
Independent inverter microprocessor control system
Full inverter protection: overcharge, over-discharge, short-circuit, overload and special PV reverse connection protection, etc.
Isolated and Pure sine wave technology:
Adopts advanced SPWM adjustment technology, high speed power MOS, using isolated transformer boosting technology, to get pure sine wave voltage with stable voltage and frequency through LC filter to the load use.
Advanced MPPT control system:
MPPT technology is an control method of Maximum Power Point Tracking,which is able to intelligently adjust the solar battery working point, making it always work on the maximum power point of I-V feature curve, to make sure the solar battery always stays at maximum power value output status under different environment. Compared with general solar charge controller, this unit can increase the power conversion efficiency of the solar panel (generated power) up to 20-30%.
Intelligent charge management:
When there is over-discharge, the system will make equalized charging compensation maintenance to the battery. When it is normally used, the system adopts combined charging manner of constant charging (constant current/constant voltage)and float charging to extend the battery service life.
High-speed synchronous conversion:
The system equipped with auto- follow Mains phase function make sure the inverter output voltage has same phase of the Mains voltage, it greatly decrease the transfer time and the surge voltage occurred during transfer.
Switch into BYPASS mode under the following four conditions
- Over Load;
- Inverter Failure
- ON: press the ON button by 3seconds. Inverter starts within 15seconds;
- OFF: press the OFF button by 3seconds.Inverter shuts down.
