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)
