Why does my SOLIS S6-GR1P5K-S Inverter show a NO-Grid error?
- J
  Joe BowmanAug 18, 2025
  If your SOLIS Inverter displays a NO-Grid error, first verify that the inverter is properly connected to the power grid. Next, check if the connected power grid is functioning normally. If the mains connection is normal, it is recommended to contact maintenance staff.

What to do if my SOLIS Inverter displays a Grid Under Voltage 01 error?
- B
  Brenda ThomasAug 21, 2025
  If the SOLIS Inverter shows a Grid Under Voltage 01 error frequently, first check the grid voltage and frequency to ensure they are within the inverter's allowable range. If they are not, contact customer service. If the voltage and frequency are within range, verify that the AC side breaker and output cable are properly connected. If the problem persists and the grid voltage and frequency are within the inverter's acceptable limits, contact customer service to modify the over-voltage and under-frequency protection points, but only after getting approval from the local power operator. If the error occurs by accident, it may be a short-term abnormality of the power grid. The inverter will resume normal work after detecting the normal power grid, and no manual intervention is required.

What causes Leakage Current Protection 01 error on SOLIS Inverter and how to fix it?
- M
  Michael RodriguezAug 23, 2025
  If your SOLIS Inverter shows a Leakage Current Protection 01 error, connect each string component individually to see if the error is caused by a component problem. If inserting one of the string components doesn't trigger an error, it indicates a problem with that specific string; check if the string is broken. If the error occurs only on rainy days or at certain times in the morning, it may be due to module aging causing excessive leakage current. This issue may resolve automatically when the weather improves or the air humidity decreases, and can be resolved through remote upgrade software.

How to troubleshoot OV-TEM error on SOLIS S6-GR1P5K-S Inverter?
- R
  Richard StephensAug 26, 2025
  If your SOLIS Inverter is showing an OV-TEM error, start by checking if the installation location meets the requirements specified in the user manual. Then, try to lower the ambient temperature around the inverter. After doing so, restart the inverter after fifteen minutes. If the error continues, contact the factory's customer service.

What should I do if my SOLIS Inverter shows Grid Over Voltage 01 error?
- C
  Cynthia LongAug 28, 2025
  If your SOLIS Inverter displays a Grid Over Voltage 01 error, and it occurs by accident, it may be due to a short-term abnormality in the power grid. The inverter should resume normal operation automatically once it detects a normal power grid. No manual intervention is required in this case.

What does OV-DC error mean on my SOLIS Inverter?
- K
  Karen GravesAug 30, 2025
  If your SOLIS Inverter displays an OV-DC error, check whether the series configuration of the PV strings is excessive. This can cause the open circuit voltage of the PV array to exceed the inverter's maximum input voltage. If this is the case, reduce the number of strings to bring the string open voltage within the inverter's specified range.

What causes the OV-BUS error on a SOLIS S6-GR1P5K-S Inverter?
- T
  Tyler RodriguezSep 1, 2025
  If your SOLIS Inverter shows an OV-BUS error, first check if the input voltage exceeds the maximum input voltage of the inverter. If it doesn't, try restarting the inverter. If the issue persists after restarting, contact the factory's customer service for further assistance.

Why is my SOLIS S6-GR1P5K-S Inverter showing a DC Bus Under Voltage 01 error?
- R
  Robert AguilarSep 4, 2025
  If your SOLIS Inverter displays a DC Bus Under Voltage 01 error, check if the input voltage is too low. If so, address the low voltage issue. Then, restart the inverter. If the problem persists, contact the factory's customer service.

What should I do if my SOLIS S6-GR1P5K-S Inverter shows an ARC-FAULT error?
- P
  Patrick WoodSep 6, 2025
  If your SOLIS Inverter displays an ARC-FAULT error, check the inverter connection for any signs of an arc. After checking the connections, restart the inverter.

How do I fix an OV-DCA-I error on my SOLIS Inverter?
- V
  Vincent ReynoldsSep 8, 2025
  If your SOLIS Inverter shows an OV-DCA-I error, check whether the MPPT of the A-way is reversed polarity. If it is not, restart the inverter. If the issue continues, contact the factory's customer service.
