5. Enstalasyon ak Enstalasyon
Proper installation is crucial for the optimal performance and longevity of your solar charge controller. Ensure all connections are secure and follow the recommended wiring sequence.
5.1. Enstalasyon Kontwolè a
- Mount the controller in a well-ventilated area, away from direct sunlight and moisture.
- Ensure sufficient clearance around the unit for proper airflow, especially around the exhaust fans and the back fence mesh design for heat dissipation.
- Kontwolè a ta dwe monte vètikalman sou yon sifas ki pa ka pran dife.
5.2. Koneksyon fil elektrik
Follow the wiring sequence below to prevent damage:
- Konekte batri a: First, connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the 12V or 24V system voltage.
- Konekte Panno Solè yo: Next, connect the solar panels to the controller's solar terminals. Verify correct polarity.
- Konekte chaj la (Si ou vle): Finalman, konekte chaj DC ou yo nan tèminal chaj kontwolè a.
The power terminals accommodate 10 AWG wiring. For optimal performance, use appropriate wire gauges for all connections.

6. Operasyon Enstriksyon
Once installed, the controller will begin operating automatically. The built-in LCD display provides real-time information about your solar system.
6.1. LCD Display and Monitoring
The blacklight LCD display shows various parameters simultaneously, including:
- Solè Panel Voltage (PV) and Current (A)
- Batri Voltage (BATT) and State of Charge (%)
- Chaj Voltage (LOAD) and Current (A)
- Cumulative power (KWH)
- Tanperati anbyen
- Charging Faults or Errors
- Load Status (ON/OFF)
The controller automatically tracks real-time data changes in these parameters, providing a comprehensive overview of your system's performance.
6.2. External Display (Optional)
An optional external display unit (LCD D485) can be connected via the RS485 communication port. This unit allows for remote monitoring and adjustment of controller functions and parameters, offering greater flexibility in system management. The external display package includes a 1.5-meter extension cable for convenient placement.
7. Antretyen
Regular maintenance ensures the long-term reliability and efficiency of your OOYCYOO MPPT Solar Charge Controller.
- Lapwòpte: Kenbe kontwolè a pwòp epi san pousyè ak debri. Sèvi ak yon twal sèk pou netwaye.
- Koneksyon: Tcheke tout koneksyon fil elektrik yo detanzantan pou asire yo sere epi yo pa gen korozyon.
- Vantilasyon: Ensure that the cooling fans and ventilation openings are not obstructed. The built-in cooling fan activates when the internal temperature exceeds 45°C and turns off below 40°C, contributing to a longer lifespan (up to 5000 hours in normal use).
- Enspeksyon batri: Regularly inspect your batteries for any signs of damage or leakage.
NAN. Depanaj
If you encounter issues with your solar charge controller, refer to the following common problems and solutions. For complex issues, please contact customer support.
