5. Configurazione e installazione

Follow these steps for proper installation of your solar charge controller.

5.1 Sequenza di cablaggio

It is crucial to connect the components in the correct sequence to prevent damage to the controller or other system components. Always connect the battery first.

Figura 5.1: Recommended wiring sequence for the LS1024B controller.

1. Collegare la batteria: Connect the battery to the charge controller's battery terminals (marked with a battery symbol). Pay close attention to polarity (+ and -). The battery indicator on the controller should turn green. If not, refer to the troubleshooting section. A battery fuse should be installed on the positive line, as close to the battery as possible (suggested distance within 150mm).
2. Collegare il pannello solare: Connect the solar panel to the charge controller's PV terminals (marked with a solar panel symbol). Ensure correct polarity.
3. Collegare il carico: Connect the DC load to the charge controller's load terminals (marked with a light bulb symbol). Ensure correct polarity.

Importante: Disconnect in the reverse order: first the solar panel, then the load, and finally the battery.

5.2 Montaggio

Mount the controller vertically on a flat, solid surface, ensuring adequate air circulation around the unit for heat dissipation. Avoid direct sunlight, high temperatures, and humid environments.

6. Istruzioni per l'uso

6.1 Indicatori LED

The LS1024B features three LED indicators to display system status:

• Charging Status LED (Solar Panel Icon):
  • Green Solid: Charging.
  • Green Flashing: Float charging.
  • Off: No charging.
• Battery Status LED (Battery Icon):
  • Green Solid: Battery full.
  • Green Flashing: Battery normal.
  • Red Solid: Battery low voltage.
  • Red Flashing: Battery over-discharge.
• Load Status LED (Light Bulb Icon):
  • Green Solid: Load ON.
  • Off: Load OFF.
  • Red Flashing: Load overload/short circuit.

6.2 Load Control Button

The blue button on the controller is used to control the DC load output and cycle through load working modes.

• Pressione breve: Toggles the load output ON/OFF (in Manual Control mode).
• Pressione lunga (5 secondi): Cycles through the load working modes. The Load Status LED will flash to indicate the current mode.

6.3 Modalità di lavoro del carico

The LS1024B supports several load working modes:

1. Controllo manuale: Load is turned ON/OFF by pressing the button.
2. Luce accesa/spenta: Il carico si accende al tramonto e si spegne all'alba.
3. Light On + Timer: Load turns ON at dusk and stays ON for a set number of hours.
4. Controllo del tempo: Load turns ON and OFF based on pre-set times (requires external programming via PC software or MT50 remote meter).

Note: Detailed configuration of "Light On + Timer" and "Time Control" modes typically requires an external communication device (e.g., MT50 remote meter or PC software via RS485 to USB cable).
