Usable and nominal energy
Nominal energy is the stated total stored energy. Usable energy is the stated amount available to draw.
Enphase IQ Battery 5P states the same 5 kWh for usable and nominal energy.
Stated temperature limits
Stated charging range: −4°F (−20°C) to 122°F (50°C).
Stated discharging range: −4°F (−20°C) to 131°F (55°C).
Battery’s stated motor-start current: up to 48 A (LRA means locked-rotor amps, a motor’s starting current). Compare starting current.

Installs
Medians require at least 20 priced installs for the named measure and period.
- Connecticut records 65 installs, 2023–2026. Source: Connecticut Energy Storage Solutions — enrollment. Median battery cost, 2023–2026: $1,566 per kWh, from 65 priced installs.
What Connecticut homes paid
All recorded installs were paired with solar PV.
Figures are medians. Parentheses give the middle half of prices. A dash means too few prices for a median.
