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.
Under the Energy Storage Safety Strategic Plan, developed with the support of the U.S. Department of Energy (DOE) Office of Electricity Delivery and Energy Reliability Energy Storage Program by Pacific Northwest Laboratory and Sandia National Laboratories, an Energy Storage Safety initiative has been underway since July 2015.
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.
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 C2 are equiped 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).
Example: PV system with 10 kW, demand of 4000 kWh/a, battery capacity should not exceed 6 kWh. The Energy Storage Inspection 2022 analyzed and compared the energy efficiency of 21 battery systems. In the reference case up to 5 kW the hybrid inverter Fronius Primo GEN24 6.0 Plus and the BYD Battery-Box Premium HVS 7.7 scored best.
DNV-RP-0043 Safety, operation and performance of grid-connected energy …
The RP focuses on three main aspects of grid-connected energy storage: safety, operation and performance. These aspects are assessed for electricity storage systems in general, i.e. a technology agnostic approach). Furthermore, recommendations applying only to specific energy storage technologies are provided wherever necessary.
