Type 1: Zero Export: to limit the exporting power to zero so that it can prevent the generated power feed back to the grid. Type 2: Export Limit: to limit the exporting power within a certain value. Type 3: Production and Consumption Monitoring: enable to measure the PV generating under a high accuracy. c. Installation Diagram.
MACTM DTU external control device with a standard RJ-45 connector. For MACTM DTU, it can support DRM0/5/6/7/8 if used with Aptos microinverters.
MACTM DTU 4. DTU Installation 4.1 System Capacity The MACTM DTU is capable of monitoring up to 99 panels. If the communication between the DTU and microinverter caused by the installation conditions, the number of PV modules that the DTU can monitor may be reduced. Note: Max. monitoring quantity is for open space, installation condition meets the requirement from both DTU and Microinverter manual, and the distance between Microinverter and DTU needs to be within the required range. 4.
