2. Turvallisuusohjeet
Please read all safety instructions carefully before installation and operation. Failure to follow these instructions may result in personal injury or damage to the controller or other components.
- Varmista, että kaikki liitännät ovat oikein ja tukevasti kiinni ennen virran kytkemistä.
- Do not disassemble or attempt to repair the controller. Refer to qualified personnel for service.
- Asenna ohjain hyvin ilmastoituun tilaan, kauas syttyvistä materiaaleista ja kosteudesta.
- Kytke aina ensin akku ohjaimeen, sitten aurinkopaneeli ja lopuksi kuorma. Irrota päinvastaisessa järjestyksessä.
- Käytä asianmukaisia henkilönsuojaimia, mukaan lukien silmäsuojaimia, työskennellessäsi akkujen ja sähköjärjestelmien kanssa.
- The controller includes multiple electronic protections such as reverse polarity, overcharge, over-discharge, overload, short-circuiting, TVS lightning, overpower, reverse current, and overtemperature protection. However, proper installation is crucial for optimal safety.

6. Käyttöohjeet
LCD Display and Parameter Settings:
The LCD display provides real-time information about your solar charging system. Use the four buttons (ESC, UP, DOWN, SET) to navigate menus and adjust parameters.
- Paina SARJA päästäksesi päävalikkoon.
- Käyttää YLÖS/ALAS to scroll through options such as battery type, load timer settings, and other customizable parameters.
- Paina SARJA again to select an option and then use YLÖS/ALAS muuttaa arvoja.
- Paina SARJA to confirm changes, or ESC poistuaksesi tallentamatta.
Latausprosessi:
The controller utilizes a smart 4-staglatausprosessi akun kunnon ja käyttöiän optimoimiseksi:
- Irtolataus: Pikalataus, jolla akku latautuu noin 80 prosenttiin.
- Absorptiomaksu: Charging at a constant voltage to bring the battery to 100% capacity.
- Kelluva veloitus: Maintaining the battery at full charge with a lower voltage.
- Equalization Charge (for specific battery types): Periodically overcharging to balance cell voltages.

Image 6: The controller features 99% high tracking efficiency and 98% peak conversion efficiency, along with a smart 4-stage latausprosessi.
USB-lataus:
The controller includes dual USB ports for charging electronic devices. These ports provide 5V DC output.
7. Huolto
Regular maintenance ensures optimal performance and extends the lifespan of your solar charge controller and battery system.
- Tarkista liitännät: Tarkista säännöllisesti kaikkien johtojen liitännät kireyden ja korroosion varalta.
- Puhdas ohjain: Pidä ohjain puhtaana pölystä ja roskista. Käytä puhdistukseen kuivaa liinaa.
- Ilmanvaihto: Ensure the installation area remains well-ventilated to prevent overheating. The controller is designed with a metal case and dual high-speed intelligent fans for enhanced heat dissipation.
- Akun tarkastus: Follow the manufacturer's maintenance guidelines for your specific battery type.
- Lämpötilan kompensointi: The controller features a temperature compensation function that automatically adjusts charging and discharging parameters to prolong battery life.
8. Vianmääritys
If you encounter issues with your controller, refer to the LCD display for error codes and consult the following common troubleshooting steps:
- Ei näyttöä: Tarkista akun liitännät ja varmista, että akussa on riittävästi virtaatage.
- Ei latausta: Verify solar panel connections and ensure adequate sunlight. Check for any fault indications on the LCD.
- Lataus ei toimi: Check load connections and ensure the load is within the controller's rated capacity. Verify load timer settings.
- Virhekoodit: The LCD display will show specific error codes for various issues (e.g., overvoltage, aliarvioitage, overtemperature, short circuit). Refer to the controller's internal error code list (if provided in a separate document) for detailed explanations and solutions.
The controller incorporates 9 intelligent protection features to safeguard your system:
