Fronius comes out on top once again in Energy Storage Inspection
achieved top results once more in the annual Energy Storage Inspection by the
Berlin University of Applied Sciences (HTW).
First place went to the Primo GEN24 6.0. Plus for the 5 kWp reference case,
while the Symo GEN24 10.0 Plus came in second for the 10 kWp reference case.
Fronius was also the only inverter manufacturer to manage this with both
products in energy efficiency class A.
The HTW Berlin Energy Storage Inspection is a study carried out
annually, involving an industry-wide comparison of PV storage systems for
private households by independent institutes. This year, 20 energy storage
systems from 15 manufacturers competed against one another and were evaluated
using the System Performance Index (SPI).
“We are pleased to achieve
such an outstanding result in the Energy Storage Inspection again. This
independent evaluation is a fantastic source of energy-efficient storage
solutions for installers and end customers. It shows us that ongoing
optimization of our products is paying off and is encouraging us to continue
with this approach,” says Martin Hackl, Global Director of the Business Unit
Solar Energy, Fronius International GmbH. “The high system efficiency means lower energy losses, which in turn
leads to higher yields and the system paying for itself more quickly,” he
The Primo GEN24 6.0 Plus together with the BYD Battery-Box
Premium HVS 7.7 achieved the highest SPI in the 5 kWp reference case. At 92.2%,
the hybrid inverter came in a whole percentage point ahead of the runner up. In
the 10 kWp reference case, the Symo GEN24 10.0 Plus with
BYD Battery-Box Premium HVS 10.2 improved upon last year’s result by 0.6%, taking it to an SPI of 94.6%.
“Although we already came first last year, we
looked closely at the optimization potential and set about making it a reality.
As a result, we came out on top once again and improved the performance. This
is due to the high conversion efficiency, made possible by the use of silicon
carbide (SiC), and also the excellent collaboration with BYD,” explains Product Manager Susanne Lampl.
Success factors: Multi
Flow Technology, silicon carbide, and strong partners Multi Flow Technology – the intelligent management of energy flows
and a factor in the device’s success1 – not only permits
simultaneous energy flows in all directions, but also AC and DC coupling of the
battery storage. The power electronics provides the basis for this. Very high conversion efficiency can be achieved through the use
of silicon-carbide-based power semiconductors, even in the case of low
utilization of several hundred watts. This has led to a
sustainable change in Fronius inverters.
Fronius and Chinese high-tech company BYD formed a
strategic partnership over four years ago. “Thanks to this excellent
collaboration, we can respond to market requirements quickly and effectively
and offer high-quality solutions,” say both Julia Chen, Global Director, BYD
Battery-Box and Martin Hackl.
