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
The solar charge controller consists of the
following components:

LED Status Meaning
Info LED illuminates
Red LED flashing quickly battery empty, state of charge < 40 %
Yellow LED illuminates battery weak, state of charge < 50 %
1. green LED illuminates battery good, state of charge > 50 %
2. green LED
green
flashes red a fault exists (see "Faults and remedies")
flashing deep-discharge deactivation, state of charge <
flashing switch-on threshold after deep-discharge deactiva-
illuminates battery full, state of charge > 80 %
flashing quickly battery full, charge regulation active,
normal operation
when the battery continues to be discharged the
deep-discharge deactivation is triggered
30 %
tion has not yet been reached,
state of charge is 40 % to 50 %
