Fault OV3 Over voltage
OV3 Fault is Over voltage DC input Voltage is Over
This ov3 fault can occur due to two reasons.
Number 1 The number of solar panels you have installed is high. The voltage of the panels is more than 800 Volte
No. 2 Your inverter has low or high value of internal equipment due to moisture and dust due to which voltage sensor is not working properly showing high voltage.
ov3 Fault Solutions
First solution
If you have installed more solar panels due to which more voltage is coming
So you can fix this ov3 fault by reducing the number of solar panels so that the voltage is around 700v
Another solution ov3 Fault
If you have installed the full number of solar panels and the amount of DC volts on your meter is less than 800 and the voltage on the inverter display is showing high, then the voltage sensor in your inverter is not working properly.
your invt vfd Desplay Fault ov3
This also has two solutions
The first solution is to get it properly repaired by a mechanic
If you want to run it immediately and repair it later, you need to know the parameter setting of the inverter.
If you know the parameter setting then you can run it in a minute
In the parameter setting you
parameter Set PE Group
The original input voltage in the PE group is set at 800 volts, you can increase the voltage as per your requirement.
If you don't get the setting, I am giving you a video link,
