User Actions for System Anomalies

Anomaly: Insulation

  • Description: Resistance between the PV module terminals and ground is too low.
  • Possible Causes: Moisture/water infiltration in DC circuit, damaged DC cables, poorly connected grounding circuit.
  • User Actions: Isolate the AC circuit by opening the AC switch/breaker. Isolate the inverter's DC circuit by opening the DC switch (if not available, contact the installer). After 3 minutes, close the DC then AC switches. If the issue persists, contact the installer.

Anomaly: Ground

  • Description: The ground leakage current value is excessive.
  • Possible Causes: Moisture/water infiltration in AC circuit, damaged AC cables.
  • User Actions: Isolate the AC circuit by opening the AC switch. Close the switch after a few seconds. If the issue persists, contact the installer.

Anomaly: Network

  • Description: Network values (voltage/frequency) are out of operation range.
  • Possible Causes: Incorrect inverter wiring to the AC network, weak or unstable network, incorrect inverter settings.
  • User Actions: Ensure the AC switch or disconnector is closed. If the issue persists, contact the installer.

Anomaly: No Network

  • Description: The inverter does not detect network voltage.
  • Possible Causes: The network is not available, incorrect AC circuit wiring, an open protection device in the AC circuit.
  • User Actions: Ensure the AC switch or disconnector is closed. If the issue persists, contact the installer.

Anomaly: PV Overvoltage

  • Description: Photovoltaic voltage exceeds inverter specifications.
  • Possible Causes: Photovoltaic module voltage is too high.
  • User Actions: Isolate the AC circuit by opening the AC switch/breaker. Isolate the inverter's DC circuit by opening the DC switch (if available). If the issue persists, contact the installer.

Inverter Anomalies

Anomaly: Coherence

  • Description: Measurements from the two microprocessors are not consistent.
  • Possible Causes: Software issue, internal circuit problem, inverter failure.
  • User Actions: Immediately isolate the inverter's AC circuit by opening the AC switch. Isolate the DC circuit by opening the DC switch (if not available, contact the installer). After 3 minutes, close the DC then AC switches. If the issue persists, contact the installer.

Anomaly: Temperature

  • Description: High temperature.
  • Possible Causes: High ambient temperature, cooling problem, inverter failure.
  • User Actions: Ensure ambient temperature is below 55°C. Check natural convection of the inverter (absence of obstacles that could block heat dissipation from the radiator). If the issue persists, contact the installer.

Anomaly: Relay

  • Description: AC relay test failed.
  • Other Anomalies: High AC injection, EEPROM fault, SCI anomaly, high or low DC bus voltage, incorrect 2.5V reference, DC sensor fault, GFCI circuit fault.
  • User Actions: Isolate the AC circuit by opening the AC switch/breaker. Isolate the inverter's DC circuit by opening the DC switch (if not available, contact the installer). After 3 minutes, close the DC then AC switches. If the issue persists, contact the installer.

Installer Actions for System Anomalies

Anomaly: Insulation

  • Installer Actions: Isolate AC and DC circuits. Check inverter grounding. Measure resistances between PV(+) & ground and PV(-) & ground. If resistances are above 2 MΩ, check DC wiring and photovoltaic modules for moisture. If one resistance is below 2 MΩ, replace the inverter. Reconnect circuits. If the issue persists, contact hotline.

Anomaly: Ground, Network, No Network

  • Installer Actions: Check AC circuit wiring and ensure protection devices are closed. Verify network voltage and frequency using SunEzy Control software. Adjust operation ranges if necessary (with energy provider approval). If the issue persists, contact hotline.

Anomaly: PV Overvoltage

  • Installer Actions: Isolate circuits and measure open-circuit voltage of the photovoltaic generator. If voltages are too close or exceed the inverter's operating limits, revise the photovoltaic generator configuration. Reconnect circuits. If the issue persists, contact hotline.

For all anomalies, important steps involve isolating circuits, checking connections, and possibly resetting or reconfiguring the system. If problems persist despite these actions, contacting a professional or the hotline for further assistance is recommended.
