The Victron Energy SmartSolar MPPT Laderegler 150V 45 is a high-performance solar charge controller designed to maximize energy harvest from solar panels using advanced Maximum Power Point Tracking (MPPT) technology. It is compatible with multiple battery voltages (12V, 24V, 36V, and 48V) and can handle up to 150V input and 45A output. This device is ideal for off-grid solar systems, RVs, boats, and other renewable energy applications.

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.
Issue | Possible Cause | Solution |
---|---|---|
No power output to the battery | Incorrect wiring or loose connections | Verify all connections and polarity |
Controller overheating | Poor ventilation or high ambient temperature | Install in a well-ventilated area |
Bluetooth not connecting | Device not in range or interference | Ensure the device is within range and free of obstructions |
Low charging efficiency | Shading on solar panels or incorrect MPPT settings | Remove shading and check configuration |
