Why does my Hoymiles HYT-5.0HV-EUG1 Inverter show Meter Reverse Connection?
If your Hoymiles Inverter indicates a Meter Reverse Connection, ensure that the installation complies with the instructions from User Manual.
What to do if my Hoymiles Inverter shows EPS Load Overpower?
If your Hoymiles Inverter displays EPS Load Overpower, it means the EPS load power is exceeding the permissible range. Reduce the power of EPS loads, or remove some EPS loads. The inverter will restart automatically.
What should I do if my Hoymiles HYT-5.0HV-EUG1 indicates an Arc Fault?
If your Hoymiles Inverter detects an Arc Fault, disconnect the DC switch and inspect the DC cables for damage. Also, check the wiring terminals for looseness or poor contact. After addressing any issues, reconnect the DC switch.
What does Isolation Fault mean on my Hoymiles HYT-5.0HV-EUG1?
An Isolation Fault on your Hoymiles Inverter indicates that the ground insulation impedance of the PV string is too low. Use a multimeter to check if the resistance between the earth and the inverter frame is close to zero; if not, ensure the connection is good. If humidity is high, try restarting the inverter when the weather improves. Check the resistance to ground from the PV module/cable and take corrective actions for short circuits or damaged insulation.
Why does my Hoymiles Inverter show Over Temperature?
If your Hoymiles Inverter shows an Over Temperature alarm, it means the internal temperature is too high. First, ensure the installation complies with the user manual's instructions. Check if a 'Fan Fault' alarm is also present; if so, replace the faulty fan.
What to do if my Hoymiles HYT-5.0HV-EUG1 displays PV Overvoltage?
If your Hoymiles Inverter displays PV Overvoltage, it means the PV voltage is higher than the permissible range. Check the specification and numbers of corresponding string PV modules.
What to do if my Hoymiles HYT-5.0HV-EUG1 shows PV Undervoltage?
If your Hoymiles Inverter displays PV Undervoltage, it means the PV voltage is lower than the permissible range. First, check the DC cable is firmly in place. Next, check for any shaded PV modules. If there are any, remove the shade and ensure the PV module is clean. Also, check for abnormal aging of the PV module.
Why does my Hoymiles HYT-5.0HV-EUG1 show PV Reverse Connection?
If your Hoymiles Inverter indicates a PV Reverse Connection, it means the PV strings are connected with reverse polarity. Verify if the corresponding string has reverse polarity. If it does, disconnect the DC switch and correct the polarity when the string current drops below 0.5A.
What to do if my Hoymiles Inverter shows Grid Overfrequency?
If your Hoymiles Inverter frequently alarms for Grid Overfrequency, it means the grid frequency is too high. First, ensure the inverter's safety country setting is correct. Next, check that your area's grid frequency is stable and within the normal range. The inverter will generally reconnect once the grid recovers.
What to do if my Hoymiles HYT-5.0HV-EUG1 Inverter shows Grid Undervoltage?
If your Hoymiles Inverter frequently alarms for Grid Undervoltage, it means the grid voltage is too low. First, ensure the inverter's safety country setting is correct. Next, check that your area's grid voltage is stable and within the normal range. Also, verify the AC cable is firmly in place. The inverter will generally reconnect once the grid voltage recovers.
