India is reviewing a new classification system called the Solar Battery Safety & Thermal Risk Index (SBTRI-2026), designed to grade home battery packs based on their safety profile, thermal runaway risk, and long-term reliability. Officials told SolSetu that this move is being considered as battery storage adoption rises sharply across urban households.

Several states have reported increasing consumer interest in hybrid rooftop systems, especially after power outages during peak summers. However, safety concerns around low-cost lithium battery imports have prompted the government to explore a regulated safety index.

Why SBTRI-2026 Is Being Considered

Based on national safety data, common risks include:

• Overheating due to poor cell thermal management
• Low-quality BMS (Battery Management Systems) failing to cut off charge
• Unverified lithium battery imports entering markets
• Poor installation practices near flammable areas
• Risks of thermal runaway in high ambient temperature zones

The index will help consumers and installers select safer, certified battery models.

How the Safety Index May Work

SBTRI-2026 may classify batteries across multiple safety markers:

• Thermal stability score under high temperature
• BMS intelligence rating (fault detection, cutoff accuracy)
• Cycle life verification under real Indian climate
• Fire propagation resistance score
• Installation safety compatibility
• Component traceability score for genuine parts

Batteries may receive safety grades from A+ (highly safe) to D (high risk).

Benefits for Consumers

• Transparent grading before purchasing storage systems
• Reduced fire hazards & improved home safety
• Long-term reliability due to verified components
• Better warranty coverage clarity

Impact on the Industry

Experts believe SBTRI-2026 will:

• Push low-quality brands out of the market
• Support Indian manufacturers producing safer battery systems
• Reduce installation-related incidents
• Increase consumer confidence in hybrid solar

Pilot States Expected for Initial Rollout

Pilot launch may begin in:

• Maharashtra
• Karnataka
• Telangana
• Gujarat
• Tamil Nadu

Home storage adoption is expected to accelerate significantly once safety clarity improves.

SolSetu will continue monitoring updates as SBTRI-2026 moves toward early-stage evaluation next year.
