Jump Start Your UL 1741 SB Testing by Leveraging QualityLogic's 1547.1 Training and Test Automation Tool

2023-06-27

Recently, we emailed our customers about how you can accelerate your device to be ready for UL 1741
SB certification by leveraging our automated IEEE 1547.1 Test Tool. Just wanted to make sure you saw
the many different benefits QualityLogic offers to accelerate the UL 1741 SB testing.

Starting late August, California will mandate UL 1741 SB certification. This deadline is quickly approaching!
If you are planning to sell your DER system in California, you will need to be UL 1741 SB certified by the
August deadline.

Join the community of manufacturers who have already adopted QualityLogic's IEEE 1547.1 test tool. This
tool fully automates the UL 1741 SB certification testing, helping to accelerate the certification process. All
the leading NRTLs responsible for certifying such devices have licensed the same QualityLogic test tools,
making the adoption of our test tool even more compelling.

QualityLogic's test tools and training have assisted numerous companies in learning, leveraging, and
accelerating their progress toward achieving UL 1741SB certification. Key benefits of our test tool, training,
and services include:
- Complete coverage of Interoperability and Type tests as specified by IEEE 1547 and UL 1741 SB
standards.
- Full support of all three DER protocols required: IEEE 2030.5, SunSpec Modbus 700, and DNP3 DER
profile.
- Fully automated management and control of lab equipment such as grid simulators, power analyzers,
oscilloscopes, and DC supplies from leading equipment brands such as Ametek, Chroma, Keysight,
Yokogawa, Dewetron, NF, Tektronix, and more.
- A proven test system that has been used by leading manufacturers and NRTLs since 2020, including
testing for V2G, PV/battery inverters, and storage systems.
- Supported by engineering staff with in-depth experience testing real inverter systems and training
manufacturers/NRTLs on IEEE 1547 and UL 1741 SB standards.
- Fully adjustable and testable values to support regional grid codes beyond the default IEEE 1547
values.
We know there's value in hearing what others think, so we wanted to share this testimonial from one of
our customers. They were recently able to accelerate their testing using our test tool.

I work as a Product Line Manager for one of the largest US residential solar and storage systems
company. The company needed to obtain Underwriters Laboratories 1741SB certification. Timing of
receiving certification was critical to remain in compliance and ensure uninterrupted installation of our
grid-connected products. The Quality Logic 1547.1 Test Tool was essential in our engineering teams
meeting the deadline for certification testing. QL was responsive with support questions and was able to
provide knowledgeable analysis support of test results.

This was the first time I have worked with QL for our compliance readiness, but it certainly will not be
the last!

If you're interested in accelerating your UL 1741 SB testing, let's arrange a meeting to discuss how we
can help.
