Your next big order is likely sitting in your past customer database. Homeowners who invested in an Enphase system a few years ago are now expanding their energy needs with air conditioning units for heating and cooling, as well as electric vehicles.

Thanks to a major new update from Enphase, you can now offer these clients expandable storage and full backup power, without making them replace the hardware they already paid for. On top of that, it’s the perfect moment to complete their home energy system with an Enphase EV Charger.

For installers, this presents a unique commercial opportunity: re-engage your installed base with high-value upgrades while protecting their previous investments.

### What does the Enphase update include?

Enphase now enables existing IQ Battery 3T and 10T (2nd generation) systems to seamlessly combine with the latest IQ Battery 5P (3rd generation) while unlocking full backup power during grid outages.

Here is what this means for your customers:

- **Expand Capacity Without Replacement:** Customers with 2nd-gen batteries can easily add an IQ Battery 5P to scale their storage. Both generations work harmoniously within the same system.
- **Grid Backup During Outages:** By adding an IQ System Controller, the system safely disconnects from the grid during a blackout and continues powering the home.
- **Seamless Software Setup:** The new functionality is unlocked via an over-the-air software update through the Enphase Installer App.

### Why this is great news for your installation business

For installers, this release isn't just a tech improvement. It's a revenue driver:

- **Re-engage past clients:** You now have a compelling reason to contact clients from previous years and offer a valuable system boost.
- **Higher margins per account:** Adding a battery module, system controller, or Enphase EV Charger is a quick retrofit that delivers immediate business growth.
- **Future-Proof trust:** Prove to your customers that choosing Enphase was the right long-term decision, as their initial investment remains fully protected.
