4.2 Uppsetningarskref
- Uppsetning: Mount the controller vertically on a non-flammable surface in a cool, dry, and well-ventilated area. Ensure adequate clearance around the unit for heat dissipation.
- Rafhlöðutenging: Connect the battery cables to the controller's BAT+ and BAT- terminals. Ensure correct polarity. The controller will automatically detect the battery voltage (12V, 24V eða 48V).
- Tenging sólarplötu: Connect the solar panel array cables to the controller's PV+ and PV- terminals. Ensure correct polarity. The controller will begin charging the battery.
- Tenging við álag (valfrjálst): If using the load output, connect your DC loads to the OUT+ and OUT- terminals. Ensure the total current draw does not exceed the controller's rated load current.
- Staðfestu tengingar: Double-check all connections for tightness and correct polarity before powering on the system.
Important: Always connect the battery first and disconnect it last. Failure to follow this sequence may damage the controller.

6. Viðhald
Reglulegt viðhald tryggir bestu mögulegu afköst og endingu sólarhleðslustýringarinnar:
- Þrif: Periodically clean the controller's exterior, especially the cooling fins and fan openings, to prevent dust buildup and ensure proper heat dissipation. Use a dry cloth.
- Tengingarathugun: Annually inspect all wiring connections for tightness and corrosion. Loose connections can cause overheating and power loss.
- Loftræsting: Gakktu úr skugga um að uppsetningarsvæðið sé vel loftræst og laust við hindranir.
- Rafhlaða skoðun: Regularly check your battery bank for signs of damage, corrosion, or electrolyte levels (for flooded batteries).
7. Bilanagreining
The LCD display can show error codes to indicate specific issues. If an error occurs, note the code and refer to the manufacturer's documentation for detailed troubleshooting steps. General troubleshooting tips include:
- Enginn skjár/Enginn rafmagn: Check battery connections and ensure the battery has sufficient voltage.
- Engin hleðsla: Verify solar panel connections, ensure sufficient sunlight, and check for any shading on the panels. Confirm PV array voltage er innan rekstrarsviðs stjórntækisins.
- Overcharging/Undercharging: Check battery type settings and charging parameters (b01, b02). Ensure the battery is healthy.
- Hleðsla virkar ekki: Check load connections, ensure the load output is enabled (b00 setting), and verify the load current does not exceed the controller's rating. Check for over-discharge protection (b03).
- Ofhitavilla: Ensure adequate ventilation around the controller. Clean any dust from cooling fins.
If the issue persists, contact MakeSkyBlue customer support.
