Fault diagnosis table
The inverter is easy to maintain. When you encounter the following problems, please
refer to the Solutions below, and contact the local distributor if the problem remains
unsolved. The following table lists some of the basic problems that may occur during
the actual operation as well as their corresponding basic solutions.

(1) Restart the inverter and wait until it functions normally;
(2) Contact customer service if error warning continues.
(1) Cut off all the power and shut down all the machines;
disconnect the load and plug in to restart machines, then
check whether the load is short circuited if the fault has
been eliminated;
(2) Contact customer service if fault remains unremoved.
(1) Cut off all the power, Restart the inverter and wait until
it functions normally.
(2) Contact customer service if error warning continues.
(1) Check the input mode setting is correct.
(2) Restart the inverter and wait until it functions normally.
(3) Contact customer service if error warning continues.
(1) Restart the inverter and wait until it functions normally.
(2) Contact customer service if error warning continues.
(1) Check for good ground connection.;
(2) Check if the earth resistance of PV+ and PV- is greater
than 2MΩ;
(3) If it is smaller than 2MΩ, check PV string for ground
fault or poor ground insulation; if it is greater than 2MΩ,
please contact the local inverter customer service once
fault is not removed.
(1) Check the input mode setting is correct.
(2) Disconnect the PV input, restart the inverter and wait
until it functions normally.
(3) Contact customer service if error warning continues.
(1) Disconnect the PV input, restart the inverter and wait
until it functions normally.
(2) Contact customer service if error warning continues.
(1) Wait five minutes for the inverter to automatically restart;
(2) Check whether the load is in compliance with the
specification;
(3) Contact customer service if error warning continues.
(1) Restart the inverter and wait until it functions normally.
(2) Contact customer service if error warning continues.
(1) Restart the inverter, restart the machine after a few
minutes of cooling, and observe whether the machine can
return to normal.
(2) Check if the ambient temperature is outside the normal
operating temperature range of the machine.
(3) Contact customer service if error warning continues.
(1) Wait one minute for the inverter to restart;
(2) Check whether the load is in compliance with the
specification;
(3) Contact customer service if error warning continues.
(1) Check if battery wiring port is short circuited;
(2) Check if charging current is in compliance with
presetting;
(3) Contact customer service if error warning continues.
(1) Restart the inverter and wait until it functions normally.
(2) Contact customer service if error warning continues.
