6.3 Fault Code
6.3.1 Short-C
Meaning: Short-circuit
Reason: Boost switch tube or output IGBT drive circuit short circuit protection
Solution: 1.Remove the short circuit line's source.
2.The load has a large capacitor, remove.
3.The output error of active devices, remove;
6.3.2 Over-C
Meaning: Over-current
Reason: When the load current is more than 1.5 times,the time longer than 1 second
Solution: 1. If the average load is too large ,reduce the same time run the device, or change a
higher power model.
2. If the output is connected to a equipment with large started transient current ,closing
the other equipment when start it, or change a larger power model.
6.3.3 Over-L
Meaning: Over-load
Reason: When the load is bigger than the rated power cumulative running time is long
Solution: 1.If the average load is too large, it needs to reduce the same time running machine,
or change a higher power model
6.3.4 Over AC
Meaning: Grid over voltge
Reason: The input of the grid voltage exceeds the device setting range
Solution: 1.The device rated-voltage is not right,reset.2:Input grid regulation difference, exceeding
the standard, input installation of the regulator
6.3.5 Over-H
Meaning: Module radiator temperature is too high
Reason: The input of the grid voltage exceeds the device setting range
Solution: 1. The environment temperature is too high, move the device to the low temperature,
cool and ventilated place;
2. The surface of the device, the internal dust too much, to clean up the dust;
3. Fan failure, replace the fan
6.3.6 Bat Low
Meaning: Battery Low voltage
Reason: Low battery
Solution: 1. Charging for the battery, or to meet the conditions of the device to charging the
battery,when the solar priority the fault is normal, as long as there is solar and battery
charging the battery will automatically reset the fault.
