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.
Solutions
(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;
