Solar / Off-Grid Energy Storage
Powering Off-Grid Markets, One Home at a Time
Lead-acid VRLA still dominates entry-level off-grid solar in 2026 because it costs $0.18/Wh, needs no BMS, tolerates abuse, and recycles 99% in target markets. The 6-CNF series is purpose-built for the punishing duty cycle of equatorial solar home systems.
Why Lead-Acid Still Wins in Off-Grid Solar
For the 600 million people who gained solar access between 2015 and 2025, lead-acid was the chemistry that made it affordable. Despite lithium's growth, VRLA gel batteries still dominate African and Southeast Asian off-grid solar because of cost-per-watt-hour economics, simplicity (no BMS), abuse tolerance, established recycling supply chain, and zero fire-risk insurance underwriting.
Tropical Climate Ready
Operates at 45°C ambient without accelerated grid corrosion. Calcium-tin alloy designed for equatorial deployments.
1200+ Cycles
Design life of 1200 cycles at 50% DoD, 600 cycles at 80% DoD. 12-year float life at 25°C — outlasts the solar panels in many cases.
Lowest $/kWh
Retail $0.18/Wh vs $0.32/Wh for lithium. Critical for affordability in subsidized solar home system rollouts.
Recyclable Supply Chain
99% lead recyclability with established collection networks in target markets. No special hazmat handling required.
