Thank you for choosing Suaoki.
Please read the instructions carefully before use and keep the manual for future
reference. In the face of uncertainty, consult a technical expert.
Safety
1. The solar controller may only be used in PV systems for charging and controlling
Lead-Acid batteries.
2. No energy source other than a solar generator may be connected to the solar
charge controller.
3. Do not connect any defective or damaged measuring equipment.
4. Follow the general and national safety and accident prevention regulation.
5. Never alter or remove the factory plates and identification labels.
6. Keep children away from PV systems.
7. Never disassemble the device.
8. One set solar module can connect with one controller only.
9. Never touch bare cables ends.
Other risks
Other risks
●Do not use the solar charge controller in dusty environments, in the vicinity of
solvents or where inflammable gases and vapors can occur.
●No open fires, flames or sparks in the vicinity of the batteries.
●Ensure that the room is adequately ventilated.
●Check the charging process regularly.
●Follow the charging instructions of the battery manufacturer.
Battery acid
●Acid splashes on skin or clothing should be immediately treated with
EN-1
soap suds and rinsed with plenty of water.
●If acid splashes into the eyes, immediately rinse with plenty of water.
Seek medical advice.
Misoperation
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 panels
and battery.
Function
The solar system controller is designed to:
●Monitor the state of charge of the battery.
●Controls the charging process.
●Control the connection/disconnection of loads.
●Make sure solar system works at proper condition.
●Manually-operated switch and light-activated sensor.

Installation
Danger of explosion due to sparks! Danger of electric shock!
●The solar charge controller may only be connected to the local loads and the
battery by trained personnel and in accordance with the applicable regulations.

LED indicator Explanation
Panel
Illuminate green light: when solar panel is charging battery.
LED off: PV voltage is lower than battery voltage or solar input
polarity is connected in wrong way, solar input would be cut off.
1. Illuminate green light: Battery is well-functioning and voltage of
battery falls within 12.5-13.6V;
2. Blink in green: Battery is fully charged and in float charging
mode, voltage of battery is 13.6-14.4V.
3. Illuminate orange light: Battery is weak. Voltage of battery falls
within 11.5-12.5V.
4. Illuminate red light: Battery is depleted. Voltage of battery is
below 11.5V.
Battery
1. Illuminate red: Polarity of battery is connected in wrong way, or
the battery voltage is below 7.5V
2. Blink in red:
●Battery is over discharged. Battery can't be charged again.
●Voltage of battery is higher than 14.4V or battery is broken.
Battery can’t be charged
●If battery is charged with a large current (>10Amp) more than
3 second, controller will cut off input of battery and red LED
would blink for 3 minutes and then light off.
●Over voltage of solar panel.
3. LED off: No abnormality is detected.
1. Illuminate white light: System provides power to load in proper
way;
2. Blink in white: If product is over-loaded (>10Amp) for 3
seconds, controller will cut off output automatically. The LED
would blink for 30 seconds and then light off.
3. LED off: No output when load is connected.
Error
Load
●Follow the installation and operating instructions for all components of the PV
system.
●Ensure that no cables are damaged.
●Ensure that polarities of Solar panel/battery/load are connected in proper way.
Mounting the solar charge controller.
●Do not mount the solar charge controller outdoors or in wet rooms.
●Do not subject the solar charge controller to direct sunshine or other source of
heat.
●Protect the solar charge controller from dirt and moisture.
●Maintain a minimum clearance of 10cm below and around the device to ensure
good air circulation.
●Mount the solar controller as close as possible to the batteries (with a safety
clearance of at least 35cm).
Fix the solar charge controller.
●Mark the position of controller fix holes on the walls;
●Drill 4×Ø6mm holes and insert dowels (not included).
●Fix the controller to the wall with the cable openings facing downwards, using 4
oval head screws M4×35 (DIN 7996).
Installation and operation
EN-4
EN-5
●Connect the wires in the sequence from 1 to 6 according the picture above.
●Disconnect the wires in the REVERSE sequence from 6 to 1 according to the
diagram above.
●Use only with 12V batteries only.
●Never exceed the nominal ratings (see technical data below).
●Suggested cable length: 10m solar panel connection cable/ 2m
battery connection cable/ 5m load connection cable.

typically 10%, receives the majority of its charge. During this stage the
battery brought to about 95% of its charger getting 100% of the available
solar power.
Pulse (Maintenance): At the end of bulk stage, typically when the battery
reach 14.4 Volts, a maintenance mode starts where the battery voltage can
float between an high and low value fixed by the controller. These values
are temperature compensated in order to keep the battery at 100% charge
stage in any condition.
Protection Mechanisms
●Overcharge protection.
●Deep discharge protection.
●Battery under voltage protection.
●Solar panel reverse current protection.
The following installation faults do not destroy the controller. After correcting fault, the
device will continue to operate correctly:
●Overcharge protection.
●Deep discharge protection.
●Reverse polarity protection of load, panel and battery.
●Automatic electronic fuse.
●Short circuit protection of load and panel.
●Over voltage protection at panel input.
●Open circuit protection without battery.
●Reverse current protection at night.
●Overload protection.
●Battery over voltage shutdown.

Maintenance
The controller is maintenance-free. We strong suggest that all components of the PV
system must be checked at least annually.
● Ensure adequate ventilation of the cooling element.
● Check the cable strain relief.
● Check that all cable connections are secure.
● Tighten screws if necessary.
● Terminal corrosion.
FAQ
No LED display
● Battery is not connected.
Remedy: unclamp connection of battery and reconnect to battery.
● Battery voltage too low.
Remedy: Pre-charge the battery.
● The external fuse in the battery connection cable has blown.
Remedy: Replace the external fuse.
● Battery is defective.
Remedy: Unclamp all connections, connect a proper battery with correct polarity
and reconnect the solar panel and loads.
