Why is there No Information (Blank Screen) on my Ginlong Inverter?
C
Colton HarrellSep 23, 2025
If your Ginlong Inverter screen is blank, it could be due to low or missing input voltage, reversed polarity, or a damaged main board. To troubleshoot: with the DC switch OFF, check the PV connections and polarity, and ensure the voltage is greater than 860V. With the DC switch ON, check again that the voltage is greater than 860V. If the DC voltage is “0”, replace the inverter.

How to fix no power on LCD of Ginlong Inverter?
T
Timothy WatersAug 26, 2025
If there is no power on the LCD of your Ginlong inverter, follow these steps:
1. Check the PV input connections.
2. Check the DC input voltage (single phase >120V, three phase >350V).
3. Check if PV+/- is reversed.

What to do for over grid voltage on Ginlong Solis Inverter?
C
Christopher AllenAug 27, 2025
If your Ginlong inverter is showing an over grid voltage error:
* The resistance of the AC cable might be too high; try changing to a larger size grid cable.
* If allowed by the electrical company, adjust the protection limit.

What to do if my Ginlong Inverter shows OV-DC: DC voltage is too high?
B
Barbara WeaverSep 14, 2025
If your Ginlong Inverter displays OV-DC, it means the DC voltage is too high. To troubleshoot: with the DC switch OFF, check the DC voltage at the inverter test points. If the DC voltage is high, there may be too many panels in the string. With the DC Switch ON, check the LCD reading, as there may be a bad measurement circuit. If the issue continues, consider replacing the inverter.

What does OV-G-V mean on my Ginlong Inverter and how to fix it?
M
Margaret RaySep 12, 2025
OV-G-V on your Ginlong Inverter indicates that it's detecting an over grid voltage. To address this: with the DC switch OFF, check the AC at the inverter. If the AC measures high, adjust the upper limit with permission from the utility. With the DC Switch ON at full power, check the AC at the inverter test points and compare with the LCD. If the AC still measures high, the cables between the inverter and interconnect might be too small. Check the ampacity and voltage drop calculations.

Why does my Ginlong Inverter say OV-G-F: Over Grid Frequency?
J
Julia HowardSep 13, 2025
The OV-G-F error on your Ginlong Inverter means it's detecting that the grid frequency is too high. To solve this: with the DC switch OFF, check the frequency at the inverter test points. If the frequency measures high, adjust the upper limit with permission from the utility. Also, check the LCD reading in case of a bad measurement circuit. With the DC Switch ON, check the grid standard. If the problem persists, the inverter may need to be replaced.

What to do if one of the DC string is reversely connected to Ginlong Solis Inverter?
B
Brian WilliamsSep 5, 2025
If one of the DC strings is reversely connected to your Ginlong inverter, check the inverter's PV string polarity. If a string is reversely connected, wait until night when solar irradiance is low and the PV string current is below 0.5A. Then, turn off the two DC switches and correct the polarity issue.
