In Comdelta, we design, built and fabricate our own Smart MPPT controller. An in-house smart Maximum Power Point Tracking (MPPT) controller is a device used to optimize the efficiency of solar panels by tracking and adjusting the operating point where the panels generate the maximum power output. MPPT controllers are especially important in solar power systems where the energy generated by solar panels is converted into electricity for various applications, such as charging batteries, powering appliances, or feeding back into the grid.

A smart MPPT controller enhances the traditional MPPT functionality by incorporating intelligent features and possibly connectivity options for remote monitoring and control. Here's a breakdown of its key components and features:

  • 1) MPPT Tracking Algorithm is the core function of an MPPT controller is to find the optimal voltage and current combination for the solar panels to maximize power output. This involves continuously tracking the panel's voltage and current characteristics to dynamically adjust the load and find the MPP (Maximum Power Point).

  • 2) Microcontroller is the controller's brain, usually a microcontroller or microprocessor, runs the MPPT algorithm, processes data from various sensors, and makes control decisions.

  • 3) Sensors is the measure device that measure environmental parameters like sunlight intensity, temperature, and battery voltage. These measurements help the controller adjust its operation based on changing conditions.

  • 4) DC-DC Converter in the MPPT controller often includes a DC-DC converter to efficiently regulate the voltage and current from the solar panels to match the battery's charging requirements. This ensures that the energy is properly stored without wasting excess power.

  • 5) Smart Features: • Remote Monitoring: A smart MPPT controller can be equipped with communication interfaces like Wi-Fi, Bluetooth, or even cellular connectivity. This allows you to monitor the system's performance, adjust settings, and receive notifications remotely via a smartphone app or web interface. • Data Logging in the controller can log data such as energy production, battery voltage, and load consumption. This data can be valuable for analysing the system's performance over time. • Energy Management: The controller can intelligently manage the flow of energy between solar panels, batteries, and loads to optimize energy usage and storage. • Adaptive Algorithm is some advanced controllers use machine learning algorithms to adapt to changing weather conditions and user behaviour, further enhancing energy optimization.

  • 6) User Interface is a smart MPPT controller might have a display screen, buttons, or a touch interface for local configuration and monitoring.

  • 7) Protection Features is to safeguard the system, the controller should have protection mechanisms against overcharging, over-discharging, short-circuiting, and other potential issues.

  • 8) Open APIs is some smart MPPT controllers provide open APIs (Application Programming Interfaces) that allow tech-savvy users to develop custom applications or integrations for specific needs.

Designing and developing an in-house smart MPPT controller involves a good understanding of electronics, microcontroller programming, power electronics, and communication protocols. In Comdelta we make sure proper safety measures and efficient algorithms to make the smart feature count the most efficient and effective for the long run lifetime of our products.

In comdelta Technologies Sdn Bhd, we are using GSM (Global System for Mobile Communications) module as the hardware component that allows our electronic devices to communicate over mobile networks using the GSM standard. GSM is a widely used cellular communication standard that enables devices like smartphones, IoT (Internet of Things) devices, and various other applications to transmit voice, text, and data wirelessly. A GSM module integrates the necessary components to establish communication with the mobile network and provides the interface for devices to send and receive data.

Key components of a GSM module include a cellular modem, a SIM card slot, an antenna connector, and various interfaces for connecting with external devices like microcontrollers or sensors.

Here's an overview of GSM communication and protocols associated with GSM modules:

  • 1) Communication Protocol: • AT Commands: GSM modules communicate with external devices using AT (Attention) commands. These are simple textual commands that are sent from the controlling device (like a microcontroller) to the GSM module to initiate various actions, such as sending a text message, making a call, or connecting to the network. • TCP/IP Stack: For data communication over the internet, many modern GSM modules also include a TCP/IP stack that allows devices to establish internet connections and communicate with remote servers.

  • 2) GSM Network Communication: • Voice Communication: GSM modules can make and receive voice calls, functioning similar to a mobile phone. • Text Messaging (SMS): GSM modules support Short Message Service (SMS), allowing devices to send and receive text messages. • Data Communication (GPRS/3G/4G): Many GSM modules support data communication over mobile networks. This can include GPRS (General Packet Radio Service), 3G, or even 4G/LTE connectivity for high-speed data transmission.

  • 3) SIM Card: GSM modules require a SIM (Subscriber Identity Module) card, which contains the necessary information to authenticate the device on the network. It also stores contact information, SMS messages, and sometimes even internet data plans.

  • 4) Data Transmission Modes: • Circuit-Switched Data (CSD): This is a traditional method where a dedicated circuit is established for data communication. It's less common now due to its limitations in speed and efficiency. • Packet-Switched Data (GPRS/3G/4G): In this mode, data is transmitted in packets over the network, allowing for more efficient use of resources and higher data rates.

  • 5) Network Protocols: • HTTP/HTTPS: Many GSM modules can communicate with web servers using HTTP/HTTPS protocols, enabling them to send data to and receive data from internet services. • SMTP/POP3: For sending and receiving emails, some GSM modules support protocols like SMTP (Simple Mail Transfer Protocol) and POP3 (Post Office Protocol 3).

  • 6) Security: • SIM Authentication: The SIM card's authentication process ensures that only authorized devices can access the network. • Data Encryption: For secure data transmission, modern GSM networks use encryption protocols to protect data from unauthorized access.

GSM modules are widely used in various applications, such as remote monitoring, vehicle tracking, smart agriculture, home automation, and more. Their ability to provide wireless communication over mobile networks makes them a crucial component in the world of IoT and connected devices.
