What to do if a faulty current sensor is detected in Hypontech HHT-12000?
If the Hypontech Inverter detects a 'faulty current sensor', disconnect the inverter from the utility grid and the PV array, and reconnect it after the LED turns off. If the fault persists, further assistance is needed.
What to do if Internal communication fault occurs in Hypontech HHT-12000 Inverter?
If the Hypontech Inverter displays an 'Internal communication fault', disconnect the inverter from the utility grid and the PV array, and reconnect it after the LED turns off. If the fault persists, further assistance is needed.
What to do if the grid frequency exceeds the permissible range in Hypontech HHT-12000?
If the Hypontech Inverter detects that the grid frequency exceeds safety regulations, it may be a short-time abnormality of the power grid, and the inverter will return to normal operation after detecting the normal power grid. If it happens frequently but automatically recovers, confirm if the grid voltage is outside the permissible range due to local grid conditions and try to modify the values of the monitored operational limits after informing the electric utility company first. If it cannot be recovered for a long time, confirm whether the AC circuit breaker is disconnected, whether the AC terminal is in good connection, whether the power supply line is normal and whether the safety regulation settings are normal.
What to do if Functional fault in Micro-Controller Unit (MCU) occurs in Hypontech HHT-12000 Inverter?
If the Hypontech Inverter displays a 'Functional fault in Micro-Controller Unit (MCU)', disconnect the inverter from the utility grid and the PV array, and reconnect it after the LED turns off. If the fault persists, further assistance is needed.
What to do if Bus Unbalance Error occurs in Hypontech HHT-12000 Inverter?
If the Hypontech Inverter displays a 'Bus Unbalance Error', disconnect the inverter from the utility grid and the PV array, and reconnect it after the LED turns off. If the fault persists, further assistance is needed.
How to fix N and PE voltage exceeds permitted range error on Hypontech HHT-12000 Inverter?
If your Hypontech Inverter shows a 'N and PE voltage exceeds permitted range' error, check if the inverter is securely grounded.
What to do if DC component of the electricity exceeds the permissible range in Hypontech Inverter?
If the Hypontech Inverter displays a 'DC component of the electricity exceeds the permissible range' error, disconnect the inverter from the utility grid and the PV array, and reconnect it after the LED turns off. If the fault persists, further assistance is needed.
What to do if a faulty grid relay is detected in Hypontech HHT-12000 Inverter?
If the Hypontech Inverter detects a 'faulty grid relay', and the difference between INV voltage and output voltage exceeds the limit, disconnect the inverter from the utility grid and the PV array, and reconnect it after the LED turns off. If the fault persists, measure the phase to phase voltage and phase to zero and zero to ground voltage with a multimeter to ensure that the voltage is normal and the zero to ground voltage value should not be greater than 10V. Disconnect the inverter from the utility grid and the PV array, and reconnect it after the LED turns off. If the fault persists, further assistance is needed.
What to do if Ground fault circuit interrupter (GFCI) exceeds the permissible range in Hypontech HHT-12000?
If the Hypontech Inverter detects a 'Ground fault circuit interrupter (GFCI) exceeds the permissible range', ensure the grounding connection of the inverter is reliable and visually inspect all PV cables and modules. If the fault persists, further assistance is needed.
How to fix Bus-voltage too high error on Hypontech HHT-12000 Inverter?
If your Hypontech Inverter shows a 'Bus-voltage too high' error, 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 permissible range when the fault occurs, further assistance is needed.
