Full explanation
LFP vs NMC (Ni-Mn-Co, Tesla Powerwall): LFP has double the cycle life (6,000 vs 3,000), 2–3× safer (no thermal runaway at 200–300°C), operates across a wider temperature range (−20 to +60°C), but is 15–25% heavier and takes 30% more space. Ukraine April 2026 price: 12 kWh LFP bank = UAH 140–180k (UAH 11.7–15k/kWh), 20 kWh = UAH 230–290k. Leading producers: BYD B-Box (China, ISO-certified), PYLONTECH (China, popular in residential PV), Dyness, Growatt, Huawei iSite-ESS, SUN Power Ukraine (local assembly with CATL/EVE cells). Detecting counterfeits (which flooded the market in 2025–26): non-original cells without BMS (Battery Management System) — work 6–12 months instead of 10–15 years; lacking deep-discharge protection they explode during charging. Verification: manufacturer serial number, IEC 62619 certificate, mass matches spec (LFP ~15–20 kg/kWh). In Ukraine, LFP is installed in 80–90% of new hybrid farm PV systems.
