2.4 Fault behaviour
Operating the solar charge controller is dangerous in the following situations:
The solar charge controller does not appear to function at all.
The solar charge controller or connected cables are visibly damaged.
Emission of smoke or fluid penetration.
When parts are loose.
In these cases immediately remove the solar charge controller from the solar
modules and battery.
3. Description
3.1 Functions
The solar charge controller
monitors the state of charge of the battery bank,
controls the charging process,
controls the connection/disconnection of loads.
This optimises battery use and significantly extends its service life.
3.2 Construction
3.3 LED displays
LED Status Meaning
Info LED illuminates
green
normal operation
flashes red a fault exists (see "Faults and remedies")
Red LED flashing quickly battery empty, state of charge < 40 %
when the battery continues to be discharged the
deep-discharge deactivation is triggered
flashing deep-discharge deactivation, state of charge <
30 %
Yellow LED illuminates battery weak, state of charge < 50 %
flashing switch-on threshold after deep-discharge deactiva-
tion has not yet been reached,
state of charge is 40 % to 50 %
1. green LED illuminates battery good, state of charge > 50 %
2. green LED
illuminates battery full, state of charge > 80 %
flashing quickly battery full, charge regulation active,
i.e. charging current reduced
