System Function
Display function
1
、
AC voltage display
When the 125VAC LED lit up, it means the AC output is 125V.
When the 230VAC LED lit up, it means the AC output is 230V.
2
、
Outage display
When the Fault LED lit up, is means there is no electricity or the output is fail, and the inverter restart.
3
、
Power shows
Power output LED: The 5 red LEDS take turns lighting, the quicker the lights move, the more power output.
4
、
AC frequency display
When the 50Hz LED lit up, it means the input frequency is 50Hz.
When the 60Hz LED lit up, it means the input frequency is 60Hz.
5
、
DC over-voltage display
When the Fault LED and the “HIGH” LED lit up, it means the DC input is over 50VDC
6
、
DC under- voltage display
When the Fault LED and the “LOW” LED lit up, it means the DC input is low 22VDC.
7
、
Power adjust display
1)
When “ST” LED flashing, it means power is in adjusting condition.
a.
When the “ST” LED and “HIGH” LED lit up, it means the power is increase.
b.
When the “ST” LED and “LOW” LED lit up, it means the power is decrease.
2) When “ST” LED long on time, is means the power is locked, and the inverter works.
6-grade power search
In overcast weather, the solar battery’s output current is extremely tiny, then inverter will automatic open
6-grade power search function.
1
、
The program can automatically open power adjustment for 6 times.
2
、
The current direction can adjust from the maximum to the minimum.
3
、
In automatic adjustment process, we will see the LOW light flashing. And the power will keep as a
starting point, from 0 to the maximum output power, and it will restart at most for 6 times, then locked
in the maximum power, the ST lamp long bright.
4
、
It need 10 minutes for 6-grade power search.

High-frequency two-way and one-way grid function
1
、
High frequency direct modulation, AC half wave synthesis
2
、
Two-way grid means: Load consume directly. And can reverse AC current transmission.
3
、
One-way grid means: Load consume directly. And banned reverse AC current transmission.
Kinds of frequency output function.
It can apply to 50Hz and 60Hz frequency of AC.
Frequency range: 45Hz ~53Hz/55Hz~ 63Hz
directly connected to the solar panels (do not need to connect the battery)
Using precise Dynamic differential pressure type MPPT function, APL functions, the inverter automatically
adjust the solar panels of maximum output power
，
simply connect the solar panel to the grid inverters. Do not
need to connect the battery.
