What to do if Hoymiles HYS-3.0LV-EUG1 Inverter displays Battery Voltage Fault?
If your Hoymiles inverter displays a Battery Voltage Fault, check if the battery input voltage is within the normal range. If the alarm persists, contact Hoymiles technical support team.
What to do if Hoymiles Inverter displays Battery Reverse Connection?
If your Hoymiles inverter detects that the battery wirings are reversely connected, check the battery for polarity correctness, and correct it if necessary. If the alarm persists, contact Hoymiles technical support team.
How to fix Meter Communication Fault on Hoymiles HYS-3.0LV-EUG1?
If your Hoymiles inverter detects a meter communication fault: 1. Check whether the Meter communication cable and terminal are abnormal. 2. Reconnect the Meter communication cable. If the alarm persists, contact Hoymiles technical support team.
What to do if the Hoymiles HYS-3.0LV-EUG1 shows Grid Overvoltage?
If your Hoymiles inverter frequently reports a grid overvoltage error, it means the grid voltage is higher than the permissible range. While the inverter should automatically reconnect once the grid voltage returns to normal, frequent alarms suggest: 1. Verify that the ESS safety configuration of the inverter is correctly configured. 2. Ensure the grid voltage in your area is stable and within the normal range. 3. Check if the cross-sectional area of the AC cable meets the requirement. If the problem persists, consider contacting Hoymiles technical support.
What to do if Hoymiles Inverter displays EPS Load Overpower?
If your Hoymiles inverter displays an EPS Load Overpower error, it means the EPS load power is higher than the permissible range. To resolve this, reduce the power of EPS loads, or remove some EPS loads. The inverter will restart automatically. If the alarm persists, contact Hoymiles technical support team.
What should I do if my Hoymiles HYS-3.0LV-EUG1 Inverter displays an Arc Fault?
If your Hoymiles inverter detects an arc fault: 1. Disconnect the DC switch and check whether the DC cables are damaged and whether the wiring terminals are loose or in poor contact. If so, take corresponding corrective measures. 2. After taking corresponding measures, reconnect the DC switch. If the alarm persists, contact Hoymiles technical support team.
What does it mean if my Hoymiles HYS-3.0LV-EUG1 displays a PV Overvoltage error?
A PV Overvoltage error on your Hoymiles inverter means the PV voltage is higher than the permissible range. Check the specification and numbers of corresponding string PV modules. If the alarm persists, contact Hoymiles technical support team.
What causes an Over Temperature error on a Hoymiles Inverter?
An Over Temperature error on your Hoymiles inverter indicates that the temperature inside the inverter is higher than the permissible range. To address this: 1. Make sure that the installation complies with the instructions from the User Manual. 2. Check whether the alarm “Fan Fault” occurs. If so, replace the faulty fan. If the alarm persists, contact Hoymiles technical support team.
How to resolve PV Undervoltage on Hoymiles HYS-3.0LV-EUG1?
A PV Undervoltage error on your Hoymiles inverter means the PV voltage is lower than the permissible range. To resolve this: 1. Check whether the DC cable is firmly in place. 2. Check whether there is a PV module shaded. If so, remove the shade and ensure the PV module is clean. 3. Check whether the PV module is in abnormal aging. If the alarm persists, contact Hoymiles technical support team.
What does it mean when my Hoymiles Inverter shows an ISO Fault?
An ISO Fault on your Hoymiles inverter indicates that the insulation impedance of the PV string to the ground is too low. To address this: 1. Use a multimeter to determine if the resistance between the earth and the inverter frame is close to zero. If not, please ensure that the connection is good. 2. If the humidity is too high, an isolation fault may occur. Attempt to restart the inverter. If the fault persists, check it again when the weather turns fine. 3. Check the resistance to ground from the PV module/ cable. Take corrective measures in case of leading to a short circuit or damaged insulation layer. If the alarm persists, contact Hoymiles technical support team.
