Description
System is normal
Battery over-discharge
Battery over-voltage, battery icon
indicator flashing fast
Battery under-voltage warning
Load short circuit
Load over current
Controller internal over temperature
Battery charge over temperature
protection
Solar panel input power excessive,
charge over current
Solar panel over voltage
Solar panel reverse polarity
Battery not connected or lithium
battery feed
Controller action
No action
Turn off load output; when the battery voltage rises to the
over discharge return voltage, the over discharge is removed,
and the load output resumes
Turn off charging; check the cause of battery over voltage,
and when voltage drops, charging automatically resumes
The battery voltage is lower than the under-voltage warning
threshold. Only alert is given, with no action
Turn off load output
Delay to turn off load at multiples of rated current
The internal temperature of controller is too high, MPPT
controller starts charging with reduced power; when the
temperature is below a certain value, charging automatically
resumes
Turn off charging, and it will automatically resume when
the temperature is below a certain value
MPPT controller charges with limited current
Solar panel over voltage; turn off charging, and it will
automatically resume when the temperature is below the
safety value
Turn off charging and discharging
As long as the solar panel voltage meets the charging
conditions, the lithium battery has constant voltage
output, and the lead-acid battery has no voltage output,
this error returns to normal after battery is connected
