Panasonic Solar & EVERVOLT Battery Support
Panasonic has discontinued its U.S. solar and battery storage business, but existing owners can still get product and warranty support.
This page explains the EVERVOLT app changes and where to find support contacts, manuals, and warranty details. You’ll also find options for adding a battery or replacing older equipment.
Synergy Power previously installed Panasonic systems. Although we no longer sell new Panasonic equipment, we can help owners review their next steps.
Is Panasonic Still Selling Solar Panels and Batteries?
Panasonic has announced the end of its U.S. solar and battery storage business. However, it says support will continue for existing customers and systems still being installed or set up.
The company also says it will honor warranties for installed and not-yet-installed products under their terms. Ending new sales does not automatically end your coverage.

What Happened to the EVERVOLT App?
The changes depend on your battery’s generation. Gen 1.5 lost its monitoring app and web portal, while Gen 3.0 moved to a different app.
EVERVOLT Gen 1.5 Monitoring App Discontinued
Panasonic ended support for the Gen 1.5 EVERVOLT System Monitoring app and web portal. This affects models EVAC-105-4/6 and EVDC-105-4/6.
The battery can still operate without the app. The change affects remote monitoring and access to settings.
How Do I Monitor a Gen 1.5 EVERVOLT Battery Now?
Use the battery system’s LCD screen to check its charge level, status, and alarms. The old app’s energy graphs and historical data are no longer available remotely.
Some settings and firmware updates require a laptop connected to the inverter. Contact Panasonic support for help with those changes.

What About the myEVERVOLT App for Gen 3.0 Systems?
Panasonic transferred Gen 3.0 app operation and monitoring to SOLAX USA on February 4, 2026. Its instructions direct owners to use SolaX Cloud with their existing myEVERVOLT login details.
If you missed the switch or cannot sign in, follow Panasonic’s linked instructions and contact support. Panasonic remains the main contact for product help and warranty claims.

Are Panasonic Solar and EVERVOLT Warranties Still Valid?
Panasonic says it will honor applicable solar and battery warranties. Your coverage depends on the product, installation date, registration, and original warranty terms.
Programs have included EVERVOLT AllGuard, AllGuard, TripleGuard, and separate panel and battery warranties. Check your warranty certificate and the documents below to confirm which terms apply. Older sales pages may describe a different program.

Panasonic EVERVOLT Solar Panels
You do not need to replace working Panasonic panels just because the company stopped selling new equipment.
Keep your system records for future repairs, roof work, warranty claims, or a home sale. Those records also help an installer review options for adding panels or battery storage.
EVERVOLT HK2 Black Series
The EVERVOLT HK2 Black Series is one of Panasonic’s all-black residential panel lines.
If you own these panels, keep their model and serial numbers with your installation paperwork, warranty documents, and system plans. These details help support teams identify the equipment and check replacement options.

EVERVOLT Home Battery
The EVERVOLT Home Battery stores electricity for later use. With the right backup setup, it can also supply power during an outage.
Your system may include battery modules, a hybrid inverter, a SmartBox, and monitoring equipment. Before requesting help, identify the battery generation and model number. That helps support staff find the right instructions and warranty terms.

EVERVOLT Hybrid Inverter
The hybrid inverter manages power moving between your solar panels, battery, home, and the grid.
If a problem occurs, note any messages on the display. Support staff may ask for photos of the screen, equipment labels, and status lights to help identify the issue.

EVERVOLT SmartBox
The SmartBox helps manage the connection between your home, battery, solar equipment, and the grid. It works with compatible EVERVOLT equipment as part of the backup power system.
For setup or troubleshooting, use the manual for your model. Older sales brochures may not include the details needed for service.
Buying a Home With Panasonic Solar or an EVERVOLT Battery
A home with Panasonic equipment may still have warranty coverage and support. Before closing, ask the seller for:
- The original contract, system plans, and installer contact details
- Panel, battery, and inverter model and serial numbers
- Warranty certificates and registration records
- Permits, inspection records, and utility permission to operate
- Monitoring instructions and account transfer details
Panasonic allows solar panel warranty rights to transfer to a new homeowner under the original agreement. Use its transfer form and confirm the terms for the equipment you are buying.
Panasonic Solar Warranty Transfer Information
Can I Add a New Battery to Panasonic Solar Panels?
Often, yes. Solar panels and batteries do not always need to come from the same brand.
Synergy Power can review your inverter, electrical panel, system age, and available space to see which batteries may work. We’ll also discuss what you want to power during an outage and how utility rules affect the project.
Working Panasonic panels may stay in place when you add a compatible battery.
Can I Expand an Existing Panasonic Solar System?
Possibly. Adding panels requires checking more than their power rating. We need to review the inverter, roof space, electrical capacity, and utility requirements.
Matching Panasonic panels may be hard to find. Depending on your equipment, a separate group of panels or a battery may be a better fit than changing the original system. Synergy Power can help you compare the options.
Frequently Asked Questions About Panasonic Solar and EVERVOLT
Did Panasonic stop making solar panels?
Panasonic has discontinued its U.S. solar and battery storage business. That change does not mean existing panels need to be replaced.
Is Panasonic going out of business?
No. Panasonic’s announcement concerns its U.S. solar and battery storage business, not the whole company.
Is my Panasonic solar warranty still valid?
Panasonic says it will honor applicable warranties. Check your original documents for the coverage, registration requirements, and terms that apply to your equipment.
Does my EVERVOLT battery still work without the app?
Gen 1.5 systems can operate without the old app or web portal. You can check basic status on the LCD screen, although some settings require a laptop connection.
Why can’t I use the EVERVOLT monitoring app?
Panasonic ended the Gen 1.5 monitoring app and web portal for EVAC-105-4/6 and EVDC-105-4/6 systems. Gen 3.0 owners should follow the separate SolaX Cloud instructions.
What happened to the Gen 3.0 myEVERVOLT app?
Gen 3.0 monitoring moved to SOLAX USA in February 2026. Panasonic directs owners to SolaX Cloud and still handles product support and warranty claims.
Can Synergy Power replace my Panasonic solar panels?
We can review your system and available replacements. An exact Panasonic match may no longer be available, so we need to check that any new equipment will work with the rest of your system.
Can Synergy Power add a battery to my Panasonic solar system?
We can assess your system for battery storage. The options depend on your inverter, electrical equipment, system design, and backup needs.
Need Help With an Existing Panasonic Solar System?
If Synergy Power installed your system, tell us which equipment you own, its model number, and what has changed or stopped working.
Even if another installer completed the project, we may be able to review options for battery storage, solar expansion, or replacement equipment.
For manufacturer warranty claims and product-specific technical help, use Panasonic’s support contacts above.
