Fox ESS Achieves Record 97% Energy Storage Efficiency under HTW Rankings

In a groundbreaking achievement, Fox ESS, a frontrunner in renewable energy solutions, has reached a new pinnacle in the field of energy storage. The company proudly announced its record System Performance Index (SPI) of 97%, which has earned them the top spot and an Efficiency Class A ranking in the storage category evaluated by HTW Berlin alongside AQUU Research.

HTW Berlin, renowned for its extensive research into energy storage technologies, provides some of the most rigorous and credible evaluations in Europe through its annual 'Energy Storage Inspection' reports. These assessments meticulously examine energy storage systems, ensuring they perform optimally under real-world conditions.

We are dedicated to advancing the Energiewende initiative, ensuring that everyone can benefit from reliable and sustainable solar energy."

Record Performance

The latest report scrutinized 12 systems, of which eight were rated based on the 10 kW SPI metric. Among these, Fox ESS's setup, featuring the PQ-H3-Ultra-10.0 inverter paired with the EQ3300-5 battery, achieved a remarkable SPI of 97%. This high level of efficiency is a testament to Fox ESS's optimized design, which strategically minimizes energy conversion losses while enhancing overall system reliability tailored for residential users.
