If your solar was installed a few years ago, you're probably exporting power for a few cents and buying it back in the evening for ten times that. A retrofit battery captures that gap — and with backup supply configured, it also keeps your home running through outages.
What's included
- Free compatibility assessment — your existing inverter, panels, metering and switchboard
- Certified installation — Tesla Powerwall Certified Reseller & Installer, Sigenergy Certified Installer; we also fit Sungrow, GoodWe and Fox ESS
- Backup supply configuration — essential circuits or whole-home, explained before you sign
- Rebate handling — current federal battery incentives applied for eligible homes
- Smart monitoring — one app for solar, storage and usage
- 5-year installation workmanship warranty
What we check before we quote
A good retrofit starts with an honest assessment: inverter make and age, export limits, switchboard capacity and space, and your evening usage pattern. If a battery doesn't stack up for your home, we'll tell you — we'd rather keep the 5.0★ rating than make a sale.
FAQs
Battery with Backup Supply Installation (Retrofit) — common questions
Will a battery work with my existing solar system?
In almost all cases, yes. AC-coupled batteries like the Tesla Powerwall work alongside any existing inverter. We confirm compatibility during the free assessment before quoting.
Do I need to replace my inverter?
Usually not. AC-coupled batteries keep your current inverter; in some cases a hybrid-inverter upgrade makes better long-term sense. We'll give you both numbers.
Can I still get a rebate on a battery-only install?
Yes — the federal battery incentive applies to retrofits on existing solar, and we handle the paperwork as part of the installation.
How long does a retrofit take?
Typically one day on site, after compatibility assessment and any required grid approval.
