The Energy Storage Inspection 2023 analyzed and compared the energy efficiency of 18 battery systems. With an average inverter efficiency in discharge mode of 97.8 % and a settling time of less than 0.2 s, new records were set. In the reference case up to 5 kW the hybrid inverters F1 and C1 scored best with an SPI (5 kW) of 92.6 %.
All manufacturers of solar energy storage systems for residential buildings were invited to take part in the Energy Storage Inspection 2022. 14 manufactures participated in the comparison of the storage systems with measurement data of 22 systems.
Laboratory tests were conducted by independent testing institutes in accordance with the "Efficiency Guideline for PV Storage Systems” (version 2.0). To each analyzed system a system abbreviation (e.g. A1) was assigned. The batteries of the AC-coupled systems A1 to B2 are equipped with battery inverters.
Simulation of the operational behavior of the PV-battery systems over a period of one year. The System Performance Index (SPI) rates the systems based on the energy flows at the grid connection point. The AC-coupled systems are assessed in combination with the PV inverters SMA Sunny Boy 5.0 (5 kW) or SMA Sunny Tripower 10.0 (10 kW).
Depending on the size of the power electronics and battery storage, the efficiency rating with the SPI (5 kW) or SPI (10 kW) is appropriate. Only systems with usable battery capacities smaller than 8.0 kWh were rated with the SPI (5 kW). 16.0 kWh was required. laboratory test.
Twice in a row the Power Storage DC 10.0 from RCT Power won the 10 kW reference case with an SPI (10 kW) of 95,1 % . In 2020 only one system scored an SPI (10 kW) over 93 %, this year already six systems managed to do so. Compared to the top performers, the total losses of a less efficient system are more than twice as high.
