Common Problems and Solutions
Symptoms
Causes and Solutions
LCD screen does not light up.
Check whether the battery is correctly connected.
Incomplete display or no renewal on LCD screen
Check whether the ambient temperature is too low and whether
the display recovers when the temperature rises.
No charging with sunlight present
Check whether the solar panel is correctly connected, and
contact is good and reliable.
Check whether the solar panel voltage falls below the battery
voltage.
The battery icon flashes quickly, and there is no output.
System overvoltage. Check whether the battery voltage is too
high.
The battery icon flashes slowly, and there is no output.
The battery is over-discharged, and will recover after recharged
adequately.
The load icon flashes quickly, and there is no output.
The load's power exceeds the rated value or the load is short-
circuited. After the problem is solved, long press the key or wait
until it recovers automatically.
Other symptoms
Check whether wiring is sound and reliable, and system voltage
is correctly recognized.
