Partner with Sinovoltaics to supervise your Factory Acceptance Testing (FAT)

Our energy storage engineers are trusted worldwide, monitoring the testing of your project-critical equipment.

Sinovoltaics' monitoring service offers performance safety and project confidence by ensuring tests are performed correctly. As a non-biased and ISO 17020 third party, we physically verify the tests and accurately collect the data. We offer the assurance that your BESS meets all specified requirements and functions reliably.

Testing standards for the Factory Acceptance Testing are agreed upon during contracting and may cover:

•    Visual Inspection

•    Electrical Testing

•    Mechanical Testing

•    Performance Testing

•    Safety Testing

Consult with our energy storage experts to understand more about our FAT supervision services. Do not hesitate to contact us.

If you know Sinovoltaics, you know we don't stop until every piece of your equipment is quality tested. We have developed proprietary software to detect potentially dangerous thermal volatility or disbalance at the battery pack and cell level. Upon request, we will implement our BESSential 100% Battery Pack Analysis to run in parallel during the FAT testing phase. Our software adds no time to manufacturing but adds safety to your system.
