4. Maintenance Features

The Aptos MAC™ DTU (Data Transfer Unit) is a crucial component in the Aptos microinverter system, acting as the communication gateway between Aptos microinverters and the Aptos Monitoring Server. Its primary function is to collect operational data from the microinverters and upload it to the monitoring server, enabling module-level monitoring for users and maintenance staff.

Function Description:

The MAC™ DTU facilitates wireless communication with Aptos microinverters using 2.4GHz Proprietary RF (Nordic) technology. It gathers essential operational data from the PV modules and microinverters, such as power output and status. This collected data is then transmitted to the Aptos Monitoring Server via an internet connection (either Wi-Fi or Ethernet), allowing for comprehensive system oversight.

Beyond basic data collection, the DTU offers advanced functionalities through its various ports:

• Export Management Function (RS485 port): This feature allows for control over power export to the grid. It supports three types of export control:
  • Zero Export: Limits exporting power to zero, preventing feedback to the grid.
  • Export Limit: Restricts exporting power to a specified value.
  • Production and Consumption Monitoring: Provides highly accurate measurement of PV generation. This function requires specific Chint Meters (DDSU666/DTSU666) or CCS WattNode Meter.
• Remote Active Power Control (RS485 port): For countries requiring generating plants to have a logic interface for active power control, the MAC™ DTU provides RTU Modbus protocol over its RS485 port. This allows for ceasing or limiting output active power to a regulating level.
• DRM Port (for Australia only): This port supports various Demand Response Modes (DRM0/5/6/7/8) when connected to an external control device with a standard RJ-45 connector. These modes dictate requirements such as operating disconnection devices, consuming/not consuming power at certain percentages of rated power, and sourcing/sinking reactive power.

Important Technical Specifications:

• System Capacity: Capable of monitoring up to 99 panels in open space with optimal installation conditions. The actual number may vary based on communication conditions.
• Wireless Communication: 2.4GHz Proprietary RF (Nordic) with a maximum distance of 200m in open space.
• Internet Connection: Supports WIFI (802.11b/g/n) and Ethernet.
• Data Sampling Rate: Per 15 minutes.
• Meter Communication: RS485 port with a maximum cable distance of 500m.
• Power Supply: External plug-in adapter.
  • Adapter input voltage/frequency: 100 to 240 V AC / 50 or 60Hz.
  • Adapter output voltage/current: 5V / 2A.
  • Power consumption: 2.5W (typical), 5W (maximum).
• Environmental Conditions:
  • Ambient temperature: -20°C to 55°C.
  • Installation environment: Away from dust, liquid, acidic, or corrosive gas.
• Physical Dimensions: 200mm × 101mm × 29mm.
• Weight: 0.20 kg.
• Mounting System: Wall mounting or Desktop mounting.
• Compliance: FCC 15B, FCC 15C, EN60950-1, EN61000-3-2, EN61000-3-3, EN301489, EN300328, EN300440, RCM.

Usage Features:

The MAC™ DTU is designed for ease of installation and monitoring:

• Interface Layout: Features clearly labeled ports for SD Card, Power, Communication (with Server and MI), Alarm, WiFi Antenna, RS485, DRM, Ethernet, USB, Reset, and 2.4G Antenna.
• Installation Flexibility: Can be wall-mounted or placed on a desktop. Wall mounting requires two #8 screws (4.166mm diameter).
• Internet Connectivity Options: Supports both Wi-Fi and Ethernet connections to the home router.
• Local Install Assistant (Installer App): A new function integrated with the DTU, accessible via a dedicated Installer App. This assistant simplifies installation by:
  • Enabling one-step Wi-Fi configuration.
  • Providing an overview of inverter status (working/abnormal) and detailed information for each microinverter.
  • Displaying signal strength between each microinverter and the DTU, allowing installers to optimize DTU placement for better connection. This helps prevent follow-up visits due to poor communication.
• Monitoring via Apps and Web Station:
  • Installer App: Used for site creation, adding DTU and microinverter IDs, designing the system layout, and checking networking status.
  • End User App: Allows customers to log in and view all system details and generation data.
  • Web Station: Provides a comprehensive platform for browsing system data and status online.
• LED Indicators: Four LED indicators (RUN, Cloud, MI, ALM) provide visual cues for the DTU's operational status, network communication, microinverter communication, and fault states. These indicators help in quick troubleshooting and status checks.

Maintenance Features:

• Troubleshooting via LED Indicators: The LED indicators offer immediate feedback on the DTU's status, helping to identify issues such as power on/off, internet disconnection, microinverter communication problems, or alarms.
• Firmware Upgrading: The DTU supports firmware upgrades, ensuring the device can be kept up-to-date with the latest features and improvements.
• Support and Contact Information: Aptos provides customer service and technical support through their website (www.aptossolar.com) and email (info@aptossolar.com). Users are advised to contact their installer or distributor for initial queries.
• Warranty Information: Disassembling the DTU without Aptos' approval will invalidate the warranty. Damaged units should be returned to the installer for repair or replacement.
• Documentation: The user manual is regularly updated, and the latest version is available on the Aptos Solar Technology website.

The MAC™ DTU is designed to be a reliable and user-friendly gateway, ensuring efficient data transfer and comprehensive monitoring for Aptos microinverter systems, ultimately contributing to optimal solar energy production and system management.
