5.2 Wiring Connections

Always follow the connection order: Battery → Load → PV. Disconnect in the reverse order: PV → Load → Battery.

  1. Connect the Battery: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the charge controller. Ensure correct polarity. The LCD display should light up.
  2. Connect the DC Load (Optional): If you have a DC load, connect its positive and negative terminals to the load terminals on the controller.
  3. Connect the Solar Panel (PV Array): Connect the positive and negative terminals of your solar panel(s) to the PV terminals on the charge controller. Ensure correct polarity. The controller will begin charging the battery.

6. Operating Instructions

6.1 LCD Display Overview

The LCD display provides real-time operational data. Use the buttons below the display to navigate through different screens and settings.

6.2 Battery Type Selection

The controller supports various battery types. It is crucial to select the correct battery type for optimal charging and to prevent damage to your battery. You can typically set this via the mobile app or directly on the controller if it has a menu option.

  • SEL: Sealed Lead-Acid Battery
  • GEL: Gel Battery
  • FLD: Flooded Lead-Acid Battery
  • AGM: Absorbed Glass Mat Battery
  • LI: Lithium-Ion Battery (LiFePO4, Li-NCM, etc.)
  • USER: User-defined parameters for custom battery types.

The charge controller supports multiple battery chemistries, including Sealed, Gel, Flooded, AGM, Lithium, and user-defined settings.

6.3 Charging Modes

The controller employs a 4-stage charging algorithm to optimize battery charging and extend battery life:

  • Bulk Charging: Charges the battery at its maximum current until it reaches the boost voltage.
  • Boost Charging: Charges at a constant voltage for a set period to ensure the battery is fully charged.
  • Float Charging: Maintains the battery at a lower voltage to compensate for self-discharge and keep it fully charged.
  • Equalize Charging (for certain battery types): Periodically overcharges the battery to balance cell voltages and prevent sulfation.

7. WiFi Connectivity and App Usage

The built-in WiFi module allows you to monitor and control your solar system remotely via a smartphone application. The app is typically named "iConnect" or "LD iConnect".

7.1 App Download and Installation
