1. Basic settings on the my-PV device

First read the installation and user manual supplied with the device, as well as the online manual.

  • The user manual for AC•THOR can be found here
  • The user manual for AC ELWA 2 can be found here
  • Make sure the device is correctly installed and connected before proceeding.

2. Settings on the my-PV device

Configure the following parameters in the web interface or via my-PV Cloud:

SettingValue / Comment
Control sourceModbus TCP
Power time-out60 seconds
AC•THOR AC ELWA 2

These settings can be applied directly on the device, via the web interface, or through my-PV Cloud.


3. Network & communication

  1. The AC•THOR or AC ELWA 2 devices are connected to ENIRIS Smartgrid One through your local network (router).
  2. Within this network, the my-PV device receives commands indicating how much power it should deliver.
Notes & Limitations
  • A maximum of 10 my-PV devices can be controlled within a single network.
  • The operating mode M3 is not supported in this configuration.
  • Do not connect the my-PV device directly to the inverter or battery system — control must occur via the network.
