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 be installed without a qualified electrician
"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 take advantage of dynamic electricity tariffs 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 600 Wp PV modules 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 .
