(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.
