4 FAQs about Maintenance of 50kW External Energy Storage Cabinet for Production Line Users

What should NREL consider when testing energy storage systems?

Photo by Owen Roberts, NREL Considerations for energy storage system testing include the following. If cost-justified by a large purchase, consider qualification testing of battery systems. Include test conditions in specifications for battery O&M diagnostics and testing.

Do energy storage products need periodic maintenance?

The requirements for periodic maintenance for energy storage products should be identified by the OEM (IEEE 2010). In settings where predictive analytics maintenance is economical, guidance should also be available from the manufacturer that identifies methodologies for assessing when a product may be approaching a failure mode.

What are the best practices for end-of-life PV waste management?

Current best practices are to minimize hazardous materials and/or design for recyclability and control of such materials (IRENA 2016). Such foresight in recyclability and management of substances may affect the eventual cost and benefits of end-of-life PV waste management.

Where can I find a NREL maintenance report?
