Installs
Medians require at least 20 priced installs for the named measure and period.
- Connecticut records 3 installs, 2026. Source: Connecticut Energy Storage Solutions — enrollment. No median battery cost per kWh: 3 priced installs (2026).
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.
| Year | Pairing | Installs | Battery cost per kWh | Total battery cost | Contract price | Up-front incentive |
|---|---|---|---|---|---|---|

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 1 install of this battery.
Recalls and safety notices
- , ACCC: SigenStor EC 8.0/10.0/12.0kW SP AU Energy Controllers
ACCC, Nov 19, 2025. Notice summary:
Hazard: The AC plugs may overheat and become damaged, posing a risk of fire.
Remedy: Firmware update that caps AC output at sustained full load, then free replacement with an updated AC plug, plus 2-year extra warranty.
Backup hours from your load
The stated usable energy divided by your load gives hours, starting with a full battery.
The spec sheet states its usable energy at 25°C.
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.
