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.
Properly grounding your inverter is crucial to avoid voltage fluctuations. In conclusion, inverter low voltage problems are not uncommon, but with the right knowledge and approach, they can be resolved. By understanding the causes behind such issues and following the appropriate diagnostics, you can get your inverter back to working optimally.
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.
