3. Veiligheidsinstruksies

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in damage to the controller, battery, or solar panels, and may void the warranty.

• Ensure the battery is connected first to allow the controller to recognize the system voltage.
• Always connect the solar panels and load after the battery.
• Disconnect the solar panels and load before disconnecting the battery.
• Install the controller in a well-ventilated, dry, and cool environment, away from flammable materials.
• Avoid touching or short-circuiting wires or terminals.
• Gebruik gepaste draaddiktes vir alle verbindings om oorverhitting te voorkom.
• This device is for indoor use only. Avoid exposure to water or excessive humidity.
• Hou buite bereik van kinders.

4. Installasie

4.1 Bedradingsvolgorde

1. Connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will display the battery voltage.
2. Connect the solar panel to the charge controller. Ensure correct polarity. The controller will begin charging the battery.
3. Connect the load to the charge controller. Ensure correct polarity.

Belangrik: Always connect the battery first and disconnect it last. This sequence prevents damage to the controller from voltage oplewing.

4.2 Montering

Mount the controller vertically on a wall or flat surface in a well-ventilated area, away from direct sunlight, high temperatures, and water. Ensure there is sufficient air circulation around the heat sink.

5. Operasie

5.1 LCD-skerm en knoppies

The controller features an LCD display and three buttons for operation: UP, DOWN, and SET.

• UP -knoppie: Navigates through display interfaces, increases parameter values.
• AFKNOP knoppie: Navigates through display interfaces, decreases parameter values.
• SET -knoppie: Enters/exits setting mode, confirms parameter changes.

5.2 Browsing Display Interfaces

Press the UP or DOWN button to cycle through various display interfaces, including battery voltage, charging current, accumulated discharge, and load status.

5.3 Parameterinstellings

To enter the setting interface, long-press the SET button for 5 seconds. Use the UP and DOWN buttons to adjust values and the SET button to confirm and move to the next parameter. Long-press SET again to save changes and exit.

Adjustable parameters include:

• Battery tipe: Select the correct battery type (e.g., Lead-Acid, Lithium).
• Laaibeheermodus: Set timer for load operation (e.g., 24H for continuous, 16H for dusk-to-dawn).
• Charge Voltage: Adjust maximum charge voltage.
• Ontslag Sny-af Voltage: Stel die minimum voltage before load disconnection.
• Discharge Reconnect Voltage: Stel die voltage at which the load reconnects.

Refer to the "Specifications" section for default and adjustable ranges for each parameter.

6. Beskermingsfunksies

The PowMr SL03-30A controller incorporates multiple protection mechanisms to ensure the safety and longevity of your solar system:

• Oorlaaibeskerming: Voorkom batteryskade as gevolg van oormatige laai.
• Oorontladingsbeskerming: Disconnects the load when battery voltage drops below a safe level.
• Kortsluitingbeskerming: Skakel outomaties af in geval van 'n kortsluiting.
• Open-circuit Protection: Protects the system if the solar panel circuit is open.
• Omgekeerde polariteitsbeskerming: Prevents damage from incorrect battery or solar panel connections.
• Oorbelastingbeskerming: Disconnects the load if current exceeds the rated limit.
• Oorverhittingbeskerming: Reduces power or shuts down if the controller's internal temperature is too high.
• Skakel geheue af: Behou instellings selfs na kragonderbreking.
