What battery chemistry do you use?

We primarily use LiFePO4 (lithium iron phosphate) for its safety, long cycle life (4,000–6,000+ cycles) and thermal stability. NMC is used for high-energy-density applications where space is constrained.

Can a BESS provide backup during grid outages?

Yes — with an appropriate islanding-capable inverter/PCS and transfer switch, a BESS can automatically support critical loads during grid outages.

How do I know what size BESS I need?

Sizing is based on your load profile, desired backup duration, solar generation profile and financial objectives. Our engineers carry out a detailed analysis before recommending system size.

Battery Energy Storage System (BESS)

Battery Energy Storage System for renewable integration and energy resilience.

Battery Energy Storage Systems (BESS) give you greater control over when and how you use energy. RS designs and integrates BESS solutions to store surplus solar generation, reduce peak-demand exposure, provide backup power, smooth renewable output and support grid-independent operation when required. From commercial facilities to utility-scale projects, our systems are engineered around your load profile, operating requirements and energy strategy.
