More info

The DTU is the key component in Hoymiles microinverter system. It works as the 
communication  gateway, which  operates between the Hoymiles microinverters and   the 
Hoymiles Monitoring Server. The DTU communicates with microinverters wirelessly via 2.4G 
RF, collecting the operating data of the system. Meanwhile, it  can also  send control 
commands  from Hoymiles Monitoring Server  to microinverters for adjusting the operation 
state. In addition, the DTU connects  to  the Internet  and communicate with  Hoymiles 
Monitoring Server. The operating data from microinverters  will be uploaded to Hoymiles 
Monitoring Server via DTU.   
The following diagram shows the DTU in the system.

    Hi, The hoymiles DTU is what model: Is it an DTU-MI-NL-HM Does it game with the CT and transmitter.Regards Charles Answer:
    Hi Charles. It is the new one with export limiting built-in Data Transfer Unit (DTU) - FBIADTUEL. However, you would still need to but the CT and transmitter separately. Regards Solar Shop Support

    Does this allow for limiting the feedback power from the micro-inverters back into the grid? Answer:
    Hi Ewert, it does , yes.

    Hi. Can this (with the micro inverters and energy meter) be used as part of a Victron Multiplus II AC-coupled (critical load side) zero grid feed-in ESS system? Everything I read on the Victron stuff says it's only possible using Fronius grid-tie inverters. Answer:
    Hi Ewert, no you can't use these for this purpose. You can use an inverter that supports frequency shift power control, but only the Fronius has a direct data link with the Victron for this purpose.

    Hi. Will this transmitter work with the Hoymiles DTU? https://za.rs-online.com/web/p/digital-power-meters/8718302/ Answer:
    Hi Ewert. If you mean in terms of export limitation then no, we doubt it.
  • Asked by Frans
    on 15/08/2019
    What CT and transmitter is required for this to block grid exporting? Kind regards Answer:
    Hi Frans, you will need to use this meter in conjunction with the DTU to prevent grid export : https://www.solar-shop.co.za/meters/285-hoymiles-single-phase-consumption-meter.html
