Phenomenon |
Problems and solutions |
|
|
When there is sunlight, the battery board indicator does not light up |
Please check if the photocell connection is correct and the contact is reliable |
|
|
Battery board charging indicator is on |
The system is over-voltage, please check whether the battery is connected reliably or the battery voltage is too high. Or the battery is fully charged. |
|
|
When the battery is connected, the LCD screen does not light or display |
Battery power supply failure, please check whether the battery connection is correct |
|
|
The load indicator flashes quickly without output |
The battery is over-discharged and under-voltage, it will automatically recover when it is full |
|
|
The load indicator flashes, no output |
If the load power exceeds the rated power, it will automatically return to normal after reducing the power consumption. |
|
|
Load indicator light is on, no output |
Please check whether the electrical equipment is connected correctly and reliably. Users can watch whether the status of the LCD screen is normal |
|
|
Other phenomena |
Check whether the wiring is reliable and whether the 12V/24V automatic recognition is correct (for models with automatic recognition) |
