To address a 'Fault 01 - 08' error on your Tsun Inverter, disconnect the AC power to the microinverter and then restart it.
Why does my Tsun TSOL-MS400 show GridVoltOverRating?
The GridVoltOverRating fault on your Tsun Inverter indicates an abnormality in the AC power grid. This issue should resolve itself when the AC power grid returns to normal. However, if the fault continues, contact Tsun service.
What to do if my Tsun Inverter displays Fault 01 - 08?
If your Tsun Inverter shows Fault 01 - 08, disconnect the AC power to restart the micro inverter. If the fault appears continuously, please contact the TSUN service.
What to do if my Tsun Inverter displays GFDI_Fault?
If your Tsun Inverter displays a GFDI_Fault, disconnect the AC power to restart the micro inverter. This fault indicates an internal issue. If the problem persists, contact Tsun service.
How to fix OverTemp on Tsun TSOL-MS400 Inverter?
If your Tsun Inverter is showing an OverTemp error, check the installation to ensure it has good heat dissipation. If the fault continues, contact Tsun service.
What to do if my Tsun Measuring Instruments display PV_Low Input Voltage?
If your Tsun Measuring Instruments are showing a PV_Low Input Voltage error, go to the site and check the connections of the photovoltaic modules to ensure that the wiring is normal.
What to do if my Tsun Measuring Instruments display No Utility?
If your Tsun Measuring Instruments display a 'No Utility' message, start by checking the AC wiring in the distribution box or socket. Also, inspect the connection and wiring of the AC connector. If the fault persists after these checks, further assistance is needed.
What to do if my Tsun Measuring Instruments display Fault11?
If your Tsun Measuring Instruments are showing 'Fault11', start by checking the system on site. Measure the voltage between PV+ and ground, and then between PV- and ground. If these two values are the same, check the system connection. If the values are different, try replacing the microinverter with a new one and test again.
