Usable and nominal energy

Nominal energy is the stated total stored energy. Usable energy is the stated amount available to draw.

Enphase IQ Battery 10C states the same 10 kWh for usable and nominal energy.

Installs

Medians require at least 20 priced installs for the named measure and period.

• Connecticut records 32 installs: 31 in 2025–2026 and 1 with no approval year. Source: Connecticut Energy Storage Solutions — enrollment. Median battery cost per kWh: $1,324, from 32 priced installs (31 in 2025–2026 and 1 with no approval year).

A count of installs says how many were installed, not how well they work. A median price is the middle reported price.

What Connecticut homes paid

All years includes 1 install with no recorded approval year.

Figures are medians. Parentheses give the middle half of prices. A dash means too few prices for a median.

Contract prices may include solar or other equipment. Prices are before the up-front incentive. Approvals run through Sep 29, 2026. Counts and prices are from the program’s Oct 1, 2026 release.

Compared with the Sep 1, 2026 release, the Oct 1, 2026 release adds 3 installs of this battery and revises the up-front incentive of 1 install.

Backup hours from your load

The stated usable energy divided by your load gives hours, starting with a full battery.

Continuous power: 7.08 kW (AC)

Backup hours follow the California Air Resources Board’s Zero Emissions Residential Backup Power Tool. Appliance figures come from the US Department of Energy’s Estimating Appliance and Home Electronic Energy Use (2012).

• The appliance figures are nameplate maximums. Average demand changes as appliances cycle and their settings change.
• A load above the stated continuous power gets no figure.
• Motor starts use three times the largest selected motor’s watts, plus the other loads. This estimate is checked against stated peak power when available. Other loads are counted at their running watts.
• Inverter and battery losses are not counted. A field study of household backup power explains the gap.
• Solar recharge, reserves, and temperature changes are outside the calculation.
