Facts and figures:

  • KfW-Energy Efficiency Home 40
    (3 units: practice, commercial unit, flat)
  • 30 kW flat roof PV system east / west
  • 40 kWh RCT storage system
  • 10 kW heat pump
  • 30,000 kWh Electricity generation/year
  • 60 % self-sufficiency

Like a piece of cake – Installing a 40 kWh power storage in no time

The project team was tasked to meet the requirements for a KfW-Energy Efficiency Home 40. In addition to a heat pump, the best storage solution for a 30 kWp photovoltaic system had to be implemented. The new building houses an animal physiotherapy practice, a sportswear shop and a residential unit. Since the storage system was installed in December 2018, 40 per cent of the energy has been supplied by solar power. During the day the stored electricity is primarily used in the practice and the commercial unit. At night it is primarily made available to the residential unit.

Michael Kaufmann of sunprojects GmbH has been operating in the PV industry for over 10 years. He is very impressed by the RCT Power storage system: "Our PV supplier SegenSolar recommended the RCT Power storage system to us. It was a piece of brilliant advice. The 40 kWh storage system is of high quality. The installation was like a walk in the park due to the simple plug-in system. Everything was just perfect. Starting with the delivery and the packaging and followed by the assembly and the installation of the four storage towers and battery inverters. The technical and customer service of RCT Power has been very competent and super friendly. I have previously installed a number of other energy storage systems. The RCT Power system is clearly the best.”

PV wholesaler SegenSolar recommended the RCT Power storage system. "We stock all the well-known storage systems. However, the RCT Power solution fitted the specific project requirements best!" says Thorsten Waldt, Key Account Manager at SegenSolar GmbH. The 'plug-and-play system' and the lightweight individual components can easily be installed by a single person. It works very reliably. In addition, installing RCT Power storage systems always runs smoothly. There are no problems, even afterwards."

Sustainable use of solar power - that is the motto of RCT Power, a manufacturer of AC- and DC-coupled, three-phase high-voltage battery storage systems. The German company from Constance offers a complete and perfectly matched system, which is characterized by a high conversion efficiency as well as extremely precise and extremely fast control. It is currently one of the most efficient PV storage systems on the market.

Benefits for the customer: He obtains a one-stop system solution from a single supplier. It also includes optimal service for all system components. Installers are also enthusiastic about the simple installation and flexible deployment options. The modular system can be retrofitted and adapts to individual customer requirements. The space-saving energy storage with lithium iron phosphate cells is characterised by high safety standards and durability. The "Fits all" technology allows all solar module types to be combined with the RCT Power storage system.

"Our customers appreciate the simple plug-in system of the RCT Power storage systems. They like the warranty provided by a single manufacturer. There is no back and forth between inverter and storage manufacturers. We cordially invite all interested parties to our guided tour of the Intersolar trade fair. During the tour we will also visit the stand of the innovative storage manufacturer RCT Power," says Ute Wimmers, Head of Sales at SegenSolar GmbH. SegenSolar relies on an extensive energy storage portfolio sourced from leading manufacturers such as RCT Power.
