Common Questions

BESS selection and installation FAQ

What size BESS do I need for peak shaving?

Start with your interval load profile, target peak reduction in kW and the duration of each peak. For example, a constant 100kW reduction for two hours requires 200kWh of delivered energy before allowing for losses, operating reserves and battery limits. Final sizing should use a site-specific assessment.

What is the difference between a cabinet and a container BESS?

A cabinet offers a compact equipment format, while a container can accommodate a larger integrated system. Compare the complete scope: battery, power conversion, cooling, controls, protection and installation access. Format alone does not establish backup capability or regulatory compliance.

What should I check before installing BESS in Singapore?

Assess the site layout, electrical connection, fire safety provisions and operating requirements with the project team. Review SCDF Fire Code Clause 10.3 for energy storage systems. Product test reports alone do not establish approval for a particular site.

How long does BESS installation take?

The programme depends on the selected configuration, equipment availability, site works, electrical integration, approvals and commissioning. Share the site details and target date to obtain a project-specific delivery programme.

Can I view specifications without downloading a brochure?

Yes. The comparison table provides key specifications available on this page. Brochures offer further model details. Confirm missing specifications, cycle-life conditions and warranty terms with Green Tenaga before selecting a system.
