The e.manager makes direct marketing (direct marketing of electricity) of photovoltaic systems, biogas plants and wind turbines easy. For this purpose, the e.manager has a so-called direct marketer interface. The integrated VPN interface establishes an encrypted connection to the direct marketer. Data on the current feed-in power and the setpoint (active power reduction) from the direct marketer are transmitted via this secure connection. The grid operator’s feed-in management is taken into account by the e.manager and, where applicable, given priority.
Thanks to the internal OpenVPN client, no external router is required.
To use this feature, you need a direct marketer licence, which you can purchase in the shop. We take care of the configuration during initial setup. To do so, please fill in the form.
Procedure:
- You can order the licence together with the device or at a later date
- Conclude a contract with a direct marketer
- If you have a contract with a direct marketer (DM) that uses Servicezeit or Integrasun as its technical service provider, such as EnBW, you must first order a chargeable certificate from them
- Fill in the form below and send it to us.
- We request the certificate from the DM; if you have already received it, please send it to us.
- Once you have installed the device on site, please let us know so that we can configure and test the DM interface.
- We register the system with the DM
- Once the system has been tested successfully, the operator receives a notification from the DM. This usually happens within the next 5 working days.

Changing direct marketer or renewing certificates
From version 2.1.1 onwards, you can replace or renew the certificates yourself.
Under Configuration => Direct marketing VPN, you can configure a new certificate. If you do not want to do this yourself, you can also commission us to do it.
- You can simply write an inline file into the Config field. The other fields then remain empty.
- If you enter the CA, Key, Cert and TLS-Auth (optional), simply omit the references to these files in the Config field. They are then generated automatically.
- If you change the protocol (licence), please contact support.
e.g. from NEXT to ServiceZeit, EWE, EMSYS, ... - "dev tun" is automatically changed to "dev tun1".
- In the Debug section you can see whether tun1 has been established.
If you do not want to do this yourself, you can also book this service from us.
