4. સેટઅપ
Follow these steps for proper installation and connection of the solar charge controller:
- માઉન્ટ કરવાનું: Mount the controller vertically on a wall or stable surface in a cool, dry, and well-ventilated area. Ensure sufficient clearance around the unit for heat dissipation.
- બેટરી કનેક્શન: Connect the battery to the controller's battery terminals first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the battery voltage.
- સોલર પેનલ કનેક્શન: Connect the solar panels to the controller's PV terminals. Ensure correct polarity. The controller will begin charging the battery.
- Load Connection (Optional): Connect your DC loads to the controller's load terminals. Ensure correct polarity.
મહત્વપૂર્ણ: Always connect the battery first, then the solar panels, and finally the load. Disconnect in the reverse order: load, then solar panels, then battery.

5. ઓપરેટિંગ સૂચનાઓ
5.1 Screen Interface Cycle
The controller's LCD display cycles through various parameters, providing real-time information about your solar system. Use the buttons to navigate or adjust settings.
Image 5.1: The screen interface cycle, illustrating different display modes for battery voltage, charging current, temperature, and fault indicators. It also shows steps for setting battery type, discharge cut-off voltage, charging cut-off voltage, ફ્લોટ વોલ્યુમtage, and load operating mode.
નોંધ: If the reading data for PV or Battery is constantly changing, the controller is actively finding the Maximum Power Point (MPP). This is normal operation. If the PV input power or voltage is insufficient, contact support.
5.2 ચાર્જિંગ મોડ્સ
The controller utilizes a 3-stage charging process to optimize battery health and performance:
- બલ્ક ચાર્જ: Charges the battery at its maximum current until voltage rises to the absorption level.
- Constant Charging (Absorption): Maintains a constant voltage, allowing the current to gradually decrease as the battery approaches full charge.
- ફ્લોટ ચાર્જ: એકવાર બેટરી સંપૂર્ણપણે ચાર્જ થઈ જાય, પછી વોલ્યુમtage is reduced to a lower level to maintain the battery at full capacity and prevent self-discharge.
