Household energy storage photovoltaic inverter test

Which inverter & high-voltage battery system solutions are the best?

Hybrid inverter and high-voltage battery system solutions from RCT Power, Energy Depot, BYD, Fronius and Kostal were on the winners‘ podium in both performance classes. The simulation-based system evaluation with the SPI also makes it possible to determine the financial impact of the efficiency losses of the tested systems.

Why are PV inverters important?

PV inverters are critical components of PV power systems and the key to ensuring that those systems have long and stable life spans. Your PV inverters must meet the related standards to perform safely and with a high level of efficiency, reliability and applicability.

Why do you test & certify your inverters & converters?

We test and certify your inverters and converters with AC output, either grid connected or in stand-alone operations, according to local and international specifications and standards to ensure their safety, quality and compliance. Successful test results can lead to certification and the right to use our internationally recognized test mark.

How to choose an inverter for a low nighttime electricity consumption?

The authors of the study advise households with a low nighttime electricity consumption to choose an inverter with a high partial load efficiency. The higher the efficiency in discharging operation of the home storage system, the lower the conversion losses and the greater the benefit of the battery system.

Are photovoltaic inverters & converters safe?

As competition in the renewable energy industry grows, companies strive to ensure their photovoltaic inverters and converters are safe, functional and compliant with relevant standards. Choosing to partner with us is the first step in meeting these goals.

What is the SPI of a PV storage system?

The SPI of a PV storage system summarizes the efficiency losses in one key figure, thus making different storage systems comparable. This year, 16 out of 20 tested systems achieved a very good SPI-value.
