The climate initiative "Kliwe" offers a flexible storage solution with zero feed-in in cooperation with REG eV
The Weiterstadt Climate Initiative (Kliwe), in cooperation with the Roßdorf Energy Community (REG eV), a new group order for plug-in solar devices – for the first time also with a universal battery storage system. The offer is aimed at residents of Weiterstadt who want to make their own electricity supply more efficient.
In cooperation with a regional supplier from Griesheim, all ordered solar systems can now be equipped with a "Venus A" type storage system from the manufacturer Marstek . The storage system has a capacity of 2.12 kilowatt hours (kWh) and can be used with both new and existing plug-in solar systems.
Easy installation and intelligent power distribution
A key feature of the new devices is the included EcoTracker system, which zero feed-in to the grid . This means that the generated solar power is used exclusively for self-consumption – surplus energy does not flow into the public grid. The system can be easily connected via the optical interface of modern electricity meters (mME) and can without a qualified electrician be installed
"With the new storage solution, citizens can cover their electricity needs even more precisely and maximize self-consumption," according to the climate initiative. The system automatically detects the current electricity demand and feeds in the self-generated electricity as needed – up to the permissible limit of 800 watts.
Versatile storage unit with emergency power function
The new Marstek Venus A is a hybrid storage system . Besides being integrated into existing solar systems, it can also operate independently – for example, to dynamic electricity tariffs take advantage of emergency power outlet delivers up to 1200 watts of power, which, when fully charged, provides approximately two hours of electricity.
The device features an integrated inverter for up to PV modules 600 Wp touchscreen with an intuitive user interface. An internet connection or cloud connection is not required.
The storage devices are expected to be available from the beginning of November 2025. Interested citizens can register for a free consultation with the Weiterstadt Climate Initiative:

Participants also receive support there if they retrofit an existing plug-in solar device .
