NOI Solar · Battery retrofit
Already have solar? Add the battery.
Most installers will not touch a system another company built. We retrofit batteries onto existing solar every week: any brand, any age, AC or DC coupled.
01 / How it works
A retrofit in three steps.
A site visit is required, and free.
- 01
Free site visit
We check your existing panels, inverter, electrical panel and where a battery can go.
- 02
Battery matched to your system
FranklinWH, Tesla Powerwall 3 or Enphase IQ Battery 5P, chosen for your solar and your backup goals.
- 03
Install and incentives
We install, commission and file the incentive paperwork. In Connecticut, Energy Storage Solutions applies.
- Existing systems
- Any brand, any age

Free solar review
Make the solar you have work in an outage.
Send us one electric bill. You get a written review of your home: what solar and a battery would cost, what they would save, and which incentives apply. Free, and free when the answer is no.
