Battery Storage Systems procurement guide
Storage systems provide backup and load shifting for solar, hybrid and standby applications. Capacity follows the autonomy period and discharge profile required. Electrical equipment must be selected as part of a system, using load, network, protection, environment and applicable project requirements.
System role and load
The stated applications are Solar hybrid energy storage, Critical load backup, Telecom and remote site power and Peak shaving and load shifting. Provide the system role, connected loads, duty, redundancy, future capacity and interfaces with existing equipment.
Ratings, compatibility and acceptance
Compare proposals against Usable capacity required in kWh, System voltage and chemistry preference, Required autonomy and discharge profile, Charge source and inverter compatibility and Installation environment and ventilation. Require source-specific drawings, datasheets, protection or coordination information and the test/standard evidence called for by the project.
Installation, protection and support
Confirm enclosure and environmental conditions, cable/termination interfaces, dimensions and weights, transport protection, site access, installation boundaries, testing, commissioning, training, warranty expectations and spare components.
Information to include in your quotation request
Send the single-line diagram or system description, load and duty, Usable capacity required in kWh, System voltage and chemistry preference, Required autonomy and discharge profile, Charge source and inverter compatibility and Installation environment and ventilation, quantity, site conditions, existing interfaces, destination, installation/testing scope and required project documents.
