NMC Battery (Nickel Manganese Cobalt)
A lithium-ion battery chemistry (LiNiMnCoO₂) with higher energy density than LFP but shorter cycle life (1,500-3,000 cycles) and higher thermal runaway risk.
Why It Matters
NMC was the dominant home battery chemistry until 2023 (LG Chem/RESU, earlier Powerwalls). Higher energy density means smaller size, but LFP's safety and longevity advantages have shifted the market.

LFP (Lithium Iron Phosphate)
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.
Cycle Life
The number of complete charge-discharge cycles a battery can perform before its capacity drops below a specified threshold (typically 70-80% of original capacity).
