Design with MPPT SCC 60A 12v-48v in Cirkit DesignerThe MPPT SCC 60A 12v-48v by PowMr is a high-performance Maximum Power Point Tracking (MPPT) solar charge controller. It is designed to maximize the efficiency of solar energy systems by dynamically adjusting the operating point of solar panels to deliver the maximum possible power to the connected batteries. This controller supports a wide range of system voltages (12V, 24V, 36V, and 48V) and can handle up to 60A of charging current, making it suitable for medium to large solar installations.
This circuit is a solar-powered battery charging system with an MPPT (Maximum Power Point Tracking) charge controller. The solar panel provides power to the MPPT SCC, which optimizes the charging of a 12V battery. A step-up boost converter is used to regulate the output voltage from the battery.

The MPPT SCC 60A has several input/output terminals and communication ports. Below is a description of the key connections:
| Pin/Port | Description |
|---|---|
| PV+ / PV- | Solar panel input terminals (positive and negative) |
| BAT+ / BAT- | Battery connection terminals (positive and negative) |
| LOAD+ / LOAD- | Output terminals for DC load connection |
| RS485 Port | Communication port for monitoring and configuration |
| Temperature Sensor | Port for connecting an external temperature sensor for battery temperature |
| Grounding Terminal | Terminal for grounding the charge controller |
The MPPT SCC 60A can be monitored using an Arduino UNO via the RS485 communication interface. Below is an example code snippet for reading data from the controller:
#include <SoftwareSerial.h>
// Define RS485 communication pins
#define RX_PIN 10 // Arduino RX pin connected to RS485 module TX
#define TX_PIN 11 // Arduino TX pin connected to RS485 module RX
SoftwareSerial rs485(RX_PIN, TX_PIN);
void setup() {
Serial.begin(9600); // Initialize Serial Monitor
rs485.begin(9600); // Initialize RS485 communication
Serial.println("MPPT SCC 60A Monitoring Started");
}
void loop() {
// Send a request to the MPPT controller (example Modbus request)
byte request[] = {0x01, 0x03, 0x00, 0x00, 0x00, 0x02, 0xC4, 0x0B};
rs485.write(request, sizeof(request));
delay(100); // Wait for response
// Read response from the controller
while (rs485.available()) {
byte response = rs485.read();
Serial.print(response, HEX);
Serial.print(" ");
}
Serial.println();
delay(1000); // Wait before sending the next request
}
Note: The above code assumes the use of an RS485-to-TTL module for communication between the Arduino and the MPPT controller. Modify the Modbus request as needed based on the controller's communication protocol.
