The open circuit voltage of the string should be much greater than the minimum input voltage of the inverter; if there are too few modules in series, the open circuit voltage of the string will be too low, resulting in no display on the inverter screen. Solution: Increase the number of solar panels in series.
Another possible cause could be an inadequate power source or improper electrical connections. Faulty wiring can also result in voltage fluctuations. If you are experiencing inverter low voltage problems, it''s essential to diagnose the issue accurately. Start by checking the battery health.
Now that we know what inverter low voltage is, let''s explore some common causes behind it. One prevalent cause could be a faulty battery. An old or damaged battery may not be able to provide sufficient power, leading to low voltage from the inverter. Another possible cause could be an inadequate power source or improper electrical connections.
Reason 3: The DC input voltage is too low. When the string output voltage is lower than the minimum input voltage of the inverter, there is no display on the inverter screen. To make sure, you can use a multimeter to measure the output voltage of the photovoltaic string to see whether the voltage reaches the minimum input voltage of the inverter.
