If the Santerno Inverter does not produce the power expected, first ensure that the air inlet filters are clean and that disconnect switches are closed on all String Boxes. Also, verify that MPPT is enabled. Check that all its input fuses are intact. In case of overheating, the inverter might be derating its output power to protect itself.
Why has my Santerno Inverter stopped by itself?
If the Santerno Inverter has stopped by itself, check the inverter Enabling/Disabling key-operated selector switch (22SA1). Also, check the status of the digital inputs by way of measurement M032 on the displays in the DC modules, ensuring MDI1 (START STOP) and MDI2 (ENABLE) are closed. The inverter stops if MDI1 is open, a stop command is sent remotely, or the Stop button is pressed.
What to do if Santerno Inverter does not start when pressing START?
If the Santerno Inverter does not start when the START button is pressed, check that the PV OK and GRID OK LEDs are ON. Also, check the status of the digital inputs (M032 measure) and ensure that the C004 Remote Command parameter is not active.
Why did the DC disconnection switch tripped on my Santerno Inverter?
If the DC disconnection switch tripped on your Santerno Inverter, check the polarity of the PV field poles and if the emergency stop button has been pressed. Check the status of the digital inputs (M032 measure), especially the key-operated selector switches on the inverter door and the AC output switch feedback signal contacts. When the disconnect switch is open RUN status is lost, press START.
What does it mean if GRID OK LED is OFF on Santerno SUNWAY TG610 1000V TE OD?
If the GRID OK LED is OFF on your Santerno Inverter, verify that the grid AC switch is closed. Also, check the AC voltage value read by the inverter, and the values of the C020 and C021 grid parameters. Finally, check the state of the external Interface Protection (AC module, terminals X6 17-20, visible on M032 MDI6).
What to check if SPDs tripped or fuses blown on Santerno SUNWAY TG610 1000V TE OD?
If SPDs tripped or fuses blown on your Santerno Inverter, make sure the DC disconnect switch is closed. If the inverter is NOT equipped with the Earthed Optional: check that voltages are balanced in relation to earth. If the inverter is equipped with the Positive Earthed Optional: check that the positive pole voltage is close to 0V. If the inverter is equipped with the Negative Earthed Optional: check that the negative pole voltage is close to 0V. Open the DC disconnect switch.
How do I troubleshoot isolation loss detected on Santerno SUNWAY TG610 1000V TE OD Inverter?
If you've detected an isolation loss on your Santerno Inverter, check if the inverter disconnect switch is closed. If the Earthed optional is not installed, with the DC disconnect switch closed, check if voltages are balanced in relation to earth. Open the DC disconnect switch. With the DC disconnect switch open, check if voltages are balanced in relation to earth and that neither is near 0V. If the Earthed optional is installed, check the state of fuses 11F1 on each DC module. Check the status of the digital inputs, M032 measure.
