9. Fault diagnosis and solutions
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.

Types Codes Solutions
Soft Time 0ut
(1) Restart the inverter and wait until it functions normally;
(2) Contact customer service if error warning continues.
INV Volt Short F01
(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.
GFCI Sensor Fail
(1) Cut off all the power, Restart the inverter and wait until it functions
normally.
(2) Contact customer service if error warning continues.
BUS Volt Low
F04
F05
(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.
Bus Volt Short F06
(1) Restart the inverter and wait until it functions normally.
(2) Contact customer service if error warning continues.
PV ISO Under Fail F07
(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 .
