Usage Instructions

How to Use the Component in a Circuit

  1. Connect the Solar Panels:

    • Connect the positive terminal of the solar panel to the PV+ input and the negative terminal to the PV- input.
    • Ensure the total voltage of the solar array does not exceed 150V.
  2. Connect the Battery:

    • Connect the positive terminal of the battery to the BAT+ terminal and the negative terminal to the BAT- terminal.
    • Ensure the battery voltage matches one of the supported levels (12V, 24V, 36V, or 48V).
  3. Optional Load Connection:

    • If you wish to power a DC load directly, connect the load's positive terminal to LOAD+ and the negative terminal to LOAD-.
  4. Enable Monitoring:

    • Use the built-in Bluetooth to pair the device with the VictronConnect app for real-time monitoring and configuration.
    • Alternatively, connect to a VE.Direct or VE.Can interface for advanced system integration.
  5. Power On:

    • Once all connections are secure, the controller will automatically start operating and track the maximum power point of the solar array.

Important Considerations and Best Practices

  • System Voltage: Ensure the battery voltage is correctly detected by the controller. The device automatically adjusts to the connected battery voltage.
  • Cable Sizing: Use appropriately sized cables to handle the current and minimize voltage drop.
  • Fusing: Install fuses or circuit breakers on both the solar input and battery output for safety.
  • Ventilation: Install the controller in a well-ventilated area to prevent overheating.
  • Firmware Updates: Regularly check for firmware updates via the VictronConnect app to ensure optimal performance.

Arduino UNO Integration Example

While the SmartSolar MPPT controller is not directly designed for Arduino integration, you can use the VE.Direct port to communicate with an Arduino for monitoring purposes. Below is an example of how to read data from the VE.Direct port using an Arduino:

#include <SoftwareSerial.h>

// Define RX and TX pins for VE.Direct communication
SoftwareSerial veDirect(10, 11); // RX = pin 10, TX = pin 11

void setup() {
  Serial.begin(9600); // Initialize Serial Monitor
  veDirect.begin(19200); // Initialize VE.Direct communication

  Serial.println("Starting VE.Direct communication...");
}

void loop() {
  // Check if data is available from the VE.Direct port
  if (veDirect.available()) {
    String data = "";
    while (veDirect.available()) {
      char c = veDirect.read();
      data += c;
    }
    // Print the received data to the Serial Monitor
    Serial.println("Received Data: " + data);
  }

  delay(1000); // Wait for 1 second before reading again
}

Note: The VE.Direct protocol requires specific parsing of data. Refer to the Victron Energy VE.Direct protocol documentation for detailed implementation.
