When defining the PV array, battery bank, and other components such as charge controllers, inverters, and DC-DC converters in the standalone feature of PVSyst, there are several error messages that users may receive if something goes wrong. Some common error messages include:

  1. The battery bank capacity is too small”: This error message occurs when the battery bank capacity defined in PVSyst is insufficient to meet the energy demands of the system. To resolve this issue, users should increase the capacity of the battery bank.

2.The maximum charge current is too high”: This error message occurs when the maximum charge current defined in PVSyst is too high for the charge controller or the battery bank. To resolve this issue, users should adjust the charge current to a lower value.

3.The inverter capacity is too small”: This error message occurs when the inverter capacity defined in PVSyst is insufficient to meet the energy demands of the system. To resolve this issue, users should increase the capacity of the inverter.

4.The PV array voltage is too high”: This error message occurs when the PV array voltage defined in PVSyst is too high for the charge controller or the inverter. To resolve this issue, users should adjust the PV array voltage to a lower value.

5.The battery voltage is out of range”: This error message occurs when the battery voltage defined in PVSyst is outside the acceptable range for the system. To resolve this issue, users should adjust the battery voltage to a value within the acceptable range.

These error messages are designed to alert users to potential issues with their system design and to help them to make the necessary adjustments to ensure that the system functions properly. By carefully reviewing these error messages and taking the appropriate action, users can ensure that their standalone PV system performs as intended.
