5. સલામતી સૂચનાઓ
- Ensure all connections are tight and secure to prevent loose connections that can cause excessive heat.
- હંમેશા બેટરીને પહેલા ચાર્જ કંટ્રોલર સાથે જોડો, પછી સોલર પેનલ અને છેલ્લે લોડ સાથે. વિપરીત ક્રમમાં ડિસ્કનેક્ટ કરો.
- Do not connect an inverter directly to the load terminals of the charge controller. Connect inverters directly to the battery.
- કંટ્રોલરને સારી રીતે વેન્ટિલેટેડ વિસ્તારમાં સ્થાપિત કરો, સીધા સૂર્યપ્રકાશ, ઉચ્ચ તાપમાન અને ભેજથી દૂર.
- સિસ્ટમ વોલ્યુમની ખાતરી કરોtage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
- Use appropriate wire gauges for all connections to prevent voltage ડ્રોપ અને ઓવરહિટીંગ.
- બેટરી સાથે કામ કરતી વખતે આંખનું રક્ષણ પહેરો.
૫. ઇન્સ્ટોલેશન (સેટઅપ)
Follow these steps for proper installation of your solar charge controller.
- માઉન્ટ કરવાનું: Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient space around the controller for heat dissipation. Use the mounting holes provided on the unit.
- બેટરી કનેક્ટ કરો: Connect the battery to the battery terminals on the charge controller. Ensure correct polarity (+ to + and - to -). The LCD display should illuminate, indicating the controller has detected the battery voltage.
- સોલાર પેનલ જોડો: Connect the solar panel to the solar panel terminals on the charge controller. Ensure correct polarity. The controller will begin charging the battery if sunlight is available.
- લોડ કનેક્ટ કરો: Connect your DC loads (e.g., lights, fans) to the load terminals. Ensure correct polarity. The USB-A port can also be used for charging compatible devices.
મહત્વપૂર્ણ જોડાણ ક્રમ: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load first, then solar panel, then battery.
