Thermal Runaway
An uncontrolled self-heating chain reaction in a battery that can lead to fire or explosion if the internal temperature exceeds a critical threshold.
Why It Matters
LFP batteries have a thermal runaway onset temperature of ~270°C vs. ~150°C for NMC — making LFP dramatically safer. This is a key reason the industry has shifted to LFP for home storage.

A lithium-ion battery chemistry (LiFePO₄) known for long cycle life (4,000-10,000 cycles), high safety (no thermal runaway), and lower energy density compared to NMC.
Battery Storage
A system that stores excess solar energy for use when the sun isn't shining, providing backup power during outages.
