What Aurora Homeowners Say About Our Energy Storage & Battery Backup Pros
Verified reviews from homeowners in Illinois
Brian K.
Aurora, IL
We lost power for 4 days after a storm last year. This year we have a Powerwall and ran the whole house through 3 outages without losing a thing. Best investment we've made.

The installer HomePro matched me with explained every option clearly and didn't push the most expensive system. We went with the Enphase 5P setup and our bills dropped significantly.

I have a home office that can't afford downtime. The FranklinWH aPower with whole-home backup has been flawless. The installer handled all permits and utility paperwork.
Energy Storage & Battery Backup in Aurora: What Homeowners Need to Know
Real cost data, decision guides, and what to look for when hiring — specific to your project.
Typical range: $12,000 – $22,000 installed (before 30% federal tax credit)
Battery storage costs are driven by system capacity, inverter configuration, electrical work required, and whether you're pairing with new solar or retrofitting onto an existing system. The federal 30% tax credit now applies to standalone batteries — no solar required.
| Option / Tier | Description | Typical Cost |
|---|---|---|
| Tesla Powerwall 3 | 13.5 kWh / 11.5 kW continuous — best for large loads & new solar installs | $12,000–$16,000 |
| Enphase IQ Battery 5P | 5 kWh per module, stackable — best for Enphase solar systems | $7,000–$10,000 per unit |
| FranklinWH aPower | 13.6 kWh — best for whole-home backup with any solar brand | $13,000–$17,000 |
| LG RESU 16H Prime | 16 kWh in a single unit — best for high-capacity, space-constrained installs | $14,000–$18,000 |
What moves the cost most:
Federal Tax Credit (ITC)
30% credit applies to standalone batteries (3+ kWh) installed after Jan 1, 2023 — no solar required.
Whole-home vs. critical load backup
Whole-home backup requires a smart panel or transfer switch, adding $2,000–$4,000 to the project.
AC vs. DC coupling
Retrofitting onto existing solar uses AC coupling. New solar installs may use DC coupling for 5–7% better efficiency.
State incentives
California SGIP, New York NY-Sun, and Hawaii programs add meaningful rebates on top of the federal credit.
Electrical panel work
Older homes may need a panel upgrade ($1,500–$3,500) before a battery can be properly installed.
The 30% federal Investment Tax Credit applies to standalone battery systems of 3 kWh or more installed after January 1, 2023 — no solar required. A $14,000 battery installation generates a $4,200 federal tax credit.
Strong case for battery storage:
- You are in an outage-prone region (Gulf Coast, Southeast, fire-prone Western states)
- Your utility has Time-of-Use pricing with peak rates 2x or more above off-peak
- Your utility has reduced or eliminated retail-rate net metering
- You have critical loads — home office, medical equipment, well pump — that cannot tolerate outages
- You're already replacing a solar inverter (natural and cost-effective upgrade moment)
Weaker case (still valid, longer payback):
- Your utility has strong net metering with full retail credit for exports
- Outages in your area are rare and brief
- Your utility rate is low with no TOU pricing
LFP vs. NMC Chemistry
Most modern residential batteries use Lithium Iron Phosphate (LFP) chemistry — including Tesla, Enphase, and FranklinWH. LFP offers superior thermal stability, 4,000–6,000+ charge cycles, and better cold-weather performance compared to the older NMC (Nickel Manganese Cobalt) chemistry found in some LG and SolarEdge systems. NMC packs more energy into a smaller space (useful when wall area is limited) but has a shorter cycle life of 3,000–4,000 cycles.
What You Can Actually Run During an Outage
A single 13.5 kWh battery with 11.5 kW continuous output (Tesla Powerwall 3) can handle a full central air conditioning system, refrigerator, lights, and several outlets simultaneously. Lower-output systems (3–5 kW) require a critical load subpanel — powering only selected circuits like the refrigerator, lights, and outlets. Paired with solar, the battery recharges during daylight hours, making multi-day outages fully manageable.
Enphase IQ Battery 5P vs. Older IQ Battery 10T
If you have an existing Enphase solar system, the current IQ Battery 5P represents a significant upgrade over the older 10T. The 10T offered 10 kWh storage but only 3.84 kW of power output. Two 5P units deliver the same 10 kWh of storage at 7.68 kW of continuous power — nearly double the output capacity, meaning more loads can run simultaneously during an outage. The 5P also replaces wireless communication with a hardwired connection for faster, more reliable system response.
