1. DESCRIPTION
• Programmable load output with lighting control mode.
• Three stage battery charging (bulk – absorption – float).
• Protected against over current.
• Protected against short circuit.
• Protected against reverse polarity connection of the battery or solar array.
• Low voltage load disconnect.
• Easy to set up thanks to two digit seven segment display.
2. INSTALLATION
The display will show a ‘’12’’ if the Controller detects a 12V battery, and a “24” if
it detects a 24V battery
Do not exceed Solar and Load ratings
3. LED INDICATORS
Green LED:
Off: No sunlight or not enough sunlight. Charger off.
Fast flashing: Bulk charge.
On: Absorption charge.
Slow flashing: Float charge.
LED=Green: battery fully charged (> 12,7V)
LED=Orange: battery ok (12,4V - 12,7V)
LED=Red: battery low (11,2V - 12,4V)
LED=Flashing Red: battery fully discharged (< 11,2V)
(load output cut off level: 11,2V)
LED=ON: load output is on.
LED=OFF: load output is off.
LED=Slow flashing: Overload.
LED=Fast flashing: Short Circuit
Please note:
1. The load output will cut off in case of over load or short circuit. The load output
will attempt to restart after 30 seconds.
2. After over discharge, the load will reconnect automatically when the battery is
recharged to 13,1V / 26,2V.
3. After over discharge, the load can be reconnected manually by pressing the
on/off push button, if the battery voltage exceeds 12,6V / 25,2V.
4. SETTING THE LOAD OUTPUT
4.1 Settings
4.2 Settings description
0 Charger only
The load output is switched off permanently.
1-13 Light control + delay
The load output automatically turns on after sunset (array voltage < 4V) and the
built-in timer starts counting.
When the timer reaches the set time, or when the low voltage limit is reached,
the load output will turn off.
H Manual
The load output can be turned on and off manually with the push button.
(low voltage shutdown remains active)
C Load output controlled by battery voltage only
Load disconnect and load reconnect will be based only on battery voltage, see
section 3
L Dusk to dawn mode
Turn on delay (array voltage < 4V): 10 seconds.
Turn off delay (array voltage > 4V): 1 minute.
No timer function.
d Debug mode
Same as L mode but without delay of 10s/1min

Standards
Safety IEC 62109-1
EMC EN 61000-6-1, EN 61000-6-3, ISO 7637-2
1) For 12V use 36 cell solar panels
For 24V use 72 cell solar panels
or 2x 36 cell in series
2) The controller switches to the lower float
voltage level 2 hours after the absorption voltage
has been reached.
Whenever the battery voltage becomes lower
than 13 V, a new charge cycle is triggered.

d Debug mode
• Always connect the batteries first, in order to allow the
Controller to recognize system voltage
• Use a 12V (36 cells) solar array for a 12V battery system.
• Use a 24V (72 cells) solar array for a 24V battery system.
