The outstanding energy efficiency of RCT Power's power storage systems was once again confirmed in 2024. As the previous year, they ranked top in the 5 kW and 10 kW performance classes in the annual Energy Storage Inspection by HTW Berlin (University of Applied Sciences). The 2024 edition of the Inspection included a new feature: The test team examined the energy efficiency of selected storage systems at low discharge capacities. The RCT Power system showed excellent results in this test category.

A home battery unit is the perfect addition to your PV system. It is one reason why residential power storage systems are becoming increasingly popular. In 2021 alone, 129,000 storage units were installed in German homes. Which power storage units are the best?

To find the answer, the Berlin University of Applied Sciences (HTW) each year performs comprehensive tests and publishes the results in its annual Energy Storage Inspection. For the 2022 edition, 21 systems from 14 manufacturers were examined. The findings show that there is still a significant variation in the efficiency scores of home power storage systems.

The most energy-efficient electricity storage system once again comes from RCT Power. In the category 10 kW, RCT Power entered with a system comprising the Power Storage DC 10.0 and Power Battery 11.5. The University of Applied Sciences (HTW) Berlin certifies 95.1 per cent energy efficiency for this system. The Constance based company is thereby once again the test winner of HTW Berlin's annual independent energy storage inspection.

In the 2022 edition, 14 manufacturers with 21 systems participated. Since large systems are generally more efficient, participating systems were grouped into 5 kW and 10 kW categories.

Thomas Hauser, Managing Director of RCT Power GmbH, explains in an interview why the energy storage inspection results are informative and relevant for consumers.

KNOWLEDGE

Our power grids have a limited capacity. There will be grid overloads if too much electricity is fed into the grid at the same time. If the overloads cause a non-supply of electricity to some consumers it is referred to as grid congestion. The power grid reaches its limitation more frequently because the required expansion progresses at a low pace. There is one answer to this problem: storing electricity in a grid-serving way. Operators of PV systems with connected power storage act as a relief for the power grid and ensure there are fewer costs for the general public.
