3.2 Ožičenje

Follow the wiring sequence below to prevent damage to the controller or battery. Always connect the battery first, then the solar panels, and finally the load.

1. Spojite bateriju: Connect the positive and negative battery wires to the corresponding battery terminals on the charge controller. Ensure a secure connection.

Video 3.2.1: Demonstrates the wiring process for the HQST MPPT Solar Charge Controller. This video shows how to connect the battery, solar panels, and load to the controller, ensuring proper polarity and secure connections for safe operation.
2. Povežite solarne panele: Connect the positive and negative solar panel wires to the corresponding PV input terminals on the charge controller. Ensure solar panels are covered or disconnected during wiring to prevent electrical shock.
3. Spojite DC opterećenje (opciono): If using a DC load directly from the controller, connect its positive and negative wires to the DC load output terminals.
4. Spojite temperaturni senzor: Plug the external temperature sensor into the designated port on the controller and attach the other end to the battery side for accurate temperature monitoring.

Video 3.2.2: Illustrates the low-temperature protection feature of the HQST 48V 60A MPPT Controller. The video demonstrates how the controller automatically stops charging when the battery temperature drops below a set threshold, protecting lithium batteries from damage.

Važno: Always ensure correct polarity (+ to + and - to -) for all connections. Incorrect wiring can damage the controller and connected devices.

4.3 Parallel Charging Setup

For higher power charging requirements, two HQST MPPT controllers of the same series (M2420N/M2440N/M4860N) can work in parallel to charge the same battery bank. A parallel charge cable (not included) is required.

1. Connect both controllers to a single battery bank.
2. Connect two solar panels to the respective controllers.
3. Plug in the RS485 parallel charge connection cable between the two controllers.
4. Press and hold the first and third buttons simultaneously on each controller until the parallel charge page appears.
5. Select "Parallel Charging ON" and press the first button to save and exit.
6. Repeat for the second controller.
