A checklist for residential energy storage systems
Nina Munzke presents the results of the KIT residential energy storage systems tests as well as a new checklist.
Revisable efficiency criteriaThe efficiency and performance of the solar battery can be classified via a short checklist with six key figures. Because the market with about 50 different manufacturers of residential energy storage systems is confusing and the data from many data sheets require lots of explanation. For battery manufacturers, it is important to have simple, verifiable and independent criteria.
The first criteria is the battery efficiency: "The battery efficiency of the 16 devices is between 78 and 98 percent," reports Nina Munzke, who coordinates the energy storage research at KIT.This results in an enormous range of 20 percentage points. "We did not rely on data in the data sheets, but on the key figures in the real operation of a reference household," she emphasizes.
