SAFETY INSTRUCTIONS

• Connect with correct polarity, red leads to the positive terminal (+), black leads to the negative terminal (—). Incorrect connections can damage the product.
• Never short-circuit the leads.
• Always conned in the following order: battery →charge controller → load → solar panel.
• Always disconnect in the following order: solar panel → load → battery.
• The output current from the charge controller must not exceed 20 A.
• The only waterproof component on the product is the solar panel.
• Allow the solar panel to charge the battery for 3 days before using the product.
• The product is not intended to be used by persons (children or adults) with any form of functional disorder unless they are supervised or have received instructions concerning the use of the product by someone who is responsible for their safety.
• Do not expose the battery to naked flames or high temperatures: risk of explosion.
• Recycle the product at the end of its useful life in accordance with local regulations.
• Do not dismantle the product or attempt to modify, or repair it.
• Disconnect the solar panel before connecting or moving the charging regulator.
• Check that the power connections are firmly tightened to minimize loss of power and the risk of overheating.
• Only charge batteries with rated data that matches the rated data of the charge controller.
• One or more batteries can be connected.
• Risk of electric shock — both the solar panel and the connected electrical equipment can generate high voltages when the charge controller is working.

INSTALLATION

Connect in the following order: battery→ charge controller → load → solar panel. Disconnect in the reverse order.

NOTE

• The switch must be in the OFF position when connecting the charging regulator. Connect the positive and negative leads with the correct polarity.
• If an inverter is used it should be connected directly to the battery, not to the load terminals on the charge controller.

USE

INTENDED USE
This product is a solar cell controller that regulates the use of energy from the small-scale production of electricity. It stores the produced electricity in a rechargeable battery. The battery can then supply DC equipment with power. The product enables the use of electrical equipment at places without a mains supply, such as at remote cottages, or for camping and outdoor life.

HOW TO USE

1. Connect the cable from the rechargeable battery to the battery terminal on the solar cell controller (marked with battery symbol), with the correct polarity.
2. Connect the electrical equipment to be supplied with power to the load terminal (marked with bulb symbol) on the controller.
3. Connect the cable from the solar panel to the solar panel terminal (marked with the solar panel symbol) on the controller with the correct polarity.
4. Mobile phones, radios, etc. can be connected to the USB port on the controller.
5. The switch on the controller should be in the ON position when supplying power to electrical equipment.

CHARGE CONTROLLER

This is a digital solar cell controller with pulse width modulation (PWM). It is cost-efficient and easy to use, with functions such as:
— 3-stage intelligent PWM charging
— boost charging, equalization charging, and float charging. – 3 battery alternative
— sealed, gel, and wet-cell battery
— status lights for battery status
— battery temperature compensation
– USB port for charging electronic equipment
— button setting of battery type and load output
— electronic safety functions.

SETTINGS

Output (load) ON/OFF
When the controller is supplied with voltage, press the button (6) to connect and disconnect the voltage to the output/load.

The setting of battery type

1. Switch to settings mode by pressing the load switch (6) for 5 seconds until the battery status light starts flashing.
2. Select the required type of battery by pressing the load switch (6).
3. The set type of battery is saved automatically if the button is not pressed for 5 seconds, and the status light stops flashing.

PROTECTIVE FEATURES

Battery overvoltage, disconnection
When the battery voltage reaches the overvoltage limit the controller stops the charging to protect the battery from damage.
Battery Undervoltage, over-discharge protection

When the battery voltage reaches the Undervoltage limit for over-discharging the controller stops the discharging of the battery to protect the battery from over-discharge damage.

Overcurrent protection
The power supply to the connected load is switched off when the current exceeds the rated current 1.25 times. The user must then reduce the connected total load and press the load switch to reconnect the load.
Short-circuit protection
The power supply to the connected load is switched off if there is a short circuit in the connected load (a short circuit is considered to have occurred if the current is 3 times more than the rated current). The user must then rectify the short circuit and press the load switch to reconnect the load.
Transient voltage suppression
The controller is protected from moderate transient overvoltages. This is only basic protection — if powerful transient overvoltages are expected, for example in areas subject to frequent thunderstorms, the protector should be supplemented with an external transient voltage protector.

TROUBLESHOOTING

correctly connected to their respective terminals and that they are firmly tightened.
All the status The lights are off.| Very low battery voltage, probably less than 8 V.| Measure the battery voltage with a multimeter. The controller needs at least 8 V to start.
The charge status indicator is flashing rapidly.| Overvoltage, battery.| Check if the battery voltage exceeds the disconnection limit, and disconnect from the solar panel.
Status light 1 flashing rapidly.| Undervoltage, battery.| The battery voltage has dropped below
the disconnection limit and the over-discharge protector has disconnected the load from the battery. When the battery voltage is restored to at least the reconnection limit, the load is reconnected.

The load status indicator is flashing slowly.| Overload.*| Disconnect one or more connected loads to
reduce the power output.
---|---|---
Press the load switch to reconnect the load.
The load status indicator is flashing slowly.| Short circuit.| Check the load and its connection,
and rectify the short circuit.
Press the load switch to reconnect the load.

• When the output current (power consumption of load) reaches 1.25, 1.5, and 2 times the rated current, the controller switches off the current automatically after 60 s, 5 s, and 1 s, respectively.
