Inverter

The energy supplier can use a smart measurement system with CLS adapter (EEBus interface) that is connected to the inverter to control the inverter via the EEBus protocol and thereby regulate the feed-in (LPP) of the PV system.

The control signals are sent from the CLS adapter to the inverter via LAN interface. To do this, the EEBus protocol just needs to be activated in the inverter and the EEBus receiver set up. The receiver is the CLS adapter, which has been fitted in the smart measurement system by the operator of the metering point and serves as a digital interface (EEBus).

DANGER

danger

Risk of death due to electrical shock and discharge!

  • De-energise device and secure against being switched on again.
  1. Connect the LAN cable correctly from the control box (CLS adapter) in accordance with the manufacturer's connection plan or connect it directly to the inverter.
  1. The connection has been established with the inverter.

Activating EEBus in the inverter

The EEBus protocol must be activated in the inverter.

  1. Call up the inverter's Webserver.
  2. Log in to the Webserver as the plant owner or installer.
  3. Select the menu item Settings > EEBus
  4. Activate EEBus.
  5. Go to Available devices and select the EEBus device, e.g. the CLS adapter, and click on it.
  6. Now pair the device in the new window that opens.
  7. The counterpart must now also pair the inverter. so that the inverter can be controlled via EEBus protocol.
  1. EEBus activated. The inverter can now be controlled by the energy supplier using the EEBus protocol. No further settings are required in the inverter.
