Sparq Stabilizer

ESS - large scale

Keep your critical infrastructure running.

SPARQ Stabilizer combines

  • Battery storage
  • Intelligent energy management
  • Smart Transfer Switch

to provide seamless transition to backup power when needed.

Seamless continuity

Static Transfer Switch ensures seamless power continuity - your systems never know the grid failed.

No more diesel

Replace costly, unreliable diesel UPS with a maintenance-free, emission-free battery system.

Standby to revenue

When not in backup mode, participate in frequency regulation markets and generate returns.

What is 'Sparq Stabilizer'?

Sparq Stabilizer delivers uninterrupted power supply (UPS) for critical infrastructure —hospitals, data centres, telecom networks, and emergency services. Combining a high-capacity BESS with a Static Transfer Switch, it provides seamless failover in milliseconds, with zero reliance on diesel backup.

Who is it for?

Hospitals, data centres, telecom operators, utilities, water treatment facilities, and any organisation where a power outage means operational failure, safety risk, or significant financial loss.
✓ “A single power outage could cost us millions — or put lives at risk.”
✓ “Our diesel UPS requires constant maintenance and fails when we need it most.”
✓ “We need to meet strict uptime SLAs but our grid is unreliable.”

“After installing Sparq Stabilizer, we decommissioned our two diesel UPS units. Maintenance costs dropped by 80% and we now earn revenue from grid services.”
