How to fix 'Bus-voltage too low' error on Hypontech HPK-1000?
If your Hypontech Inverter shows a 'Bus-voltage too low' error, check the open-circuit voltages of the strings and make sure it is below the maximum DC input voltage of the inverter. If the input voltage lies within the permissible range while the fault occurs, contact the service.
How to fix 'Bus-voltage too high' error on Hypontech HPK-1000?
If your Hypontech Inverter shows a 'Bus-voltage too high' error, check the open-circuit voltages of the strings and make sure it is below the maximum DC input voltage of the inverter. If the input voltage lies within the permissible range while the fault occurs, contact the service.
What to do if the grid frequency exceeds the permissible range in Hypontech HPK-1000?
If your Hypontech Inverter shows 'Grid frequency exceeds the permissible range', it may be due to a temporary issue with the power grid, and the inverter should return to normal operation automatically. If it happens frequently, check if the grid voltage is outside the permissible range due to local grid conditions and consider modifying the monitored operational limits after informing the electric utility company.
What to do if Ground fault circuit interrupter (GFCI) exceeds the permissible range in Hypontech Inverter?
If your Hypontech Inverter displays 'Ground fault circuit interrupter (GFCI) exceeds the permissible range', ensure the grounding connection of the inverter is reliable. Also, perform a visual inspection of all PV cables and modules. If the fault persists, contact the service.
What causes 'PV voltage too high' error in Hypontech Inverter?
If your Hypontech Inverter displays 'PV voltage too high', check the open-circuit voltages of the strings to ensure they are below the maximum DC input voltage of the inverter. If the input voltage is within the correct range when the fault occurs, contact the service.
Why is my Hypontech Inverter temperature too high?
If your Hypontech Inverter indicates that the inverter temperature is too high, check if the airflow to the heat sink is obstructed and if the installation site is in direct sunlight or if the ambient temperature around the inverter is too high. If all these conditions are normal, contact the service.
What to do if Hypontech HPK-1000 shows 'Utility grid disconnected'?
If your Hypontech Inverter shows that the utility grid is disconnected, it may be a short-term issue with the power grid. The inverter should return to normal operation once the power grid is stable. If it doesn't recover, check if the AC circuit breaker is disconnected, the AC terminal or fuse is in good contact, and whether the power supply line is normal. If the issue remains, contact the service.
