Panasonic Solar & EVERVOLT Battery Support
Panasonic has discontinued its solar panel and battery storage business in the United States, but that does not mean existing Panasonic solar and EVERVOLT systems are no longer supported.
If you already own Panasonic solar panels, an EVERVOLT battery, hybrid inverter, or SmartBox, this page will help you understand what has changed, where to find warranty information, and how to get support for your equipment.
Synergy Power previously installed Panasonic solar and energy storage equipment. While we no longer offer new Panasonic systems, we want our customers and other Panasonic system owners to have a clear place to find current information.
Is Panasonic Still Selling Solar Panels and Batteries?
No. Panasonic has announced that it is discontinuing its solar and battery storage business line in the United States.
Panasonic has also stated that it will continue supporting existing customers and customers with installations still undergoing commissioning. According to Panasonic, warranties for installed products and qualifying products that have not yet been installed will continue to be honored according to their applicable warranty terms.
This means owners of Panasonic EVERVOLT solar panels and battery systems should not assume that their product warranty disappeared simply because Panasonic stopped selling new equipment.

What Happened to the EVERVOLT App?
This depends on which generation of EVERVOLT energy storage system you own.
Panasonic has announced different changes for its Gen 1.5 and Gen 3.0 EVERVOLT systems.
EVERVOLT Gen 1.5 Monitoring App Discontinued
Panasonic discontinued the EVERVOLT System Monitoring mobile application and web portal used with its Gen 1.5 energy storage systems.
This change applies to the following models:
- EVAC-105-4/6
- EVDC-105-4/6
Panasonic states that the EVERVOLT System Monitoring app and web portal are no longer available for download, use, or support.
The battery system itself can continue operating without the app. The change affects remote monitoring and configuration, not the basic ability of the energy storage hardware to operate locally.
How Do I Monitor a Gen 1.5 EVERVOLT Battery Now?
Without the former EVERVOLT monitoring app, Panasonic directs homeowners to use the LCD display located on the energy storage system for basic information.
The LCD can provide information such as:
- Battery state of charge
- Current system status
- Basic system operating information
- Alarm information used for troubleshooting
Some advanced settings require a direct connection to the inverter using a laptop. These include certain battery reserve settings, charging and discharging settings, and firmware functions.
One important limitation is that the historical daily energy graphs previously available through the app are no longer remotely available for Gen 1.5 systems.

What About the myEVERVOLT App for Gen 3.0 Systems?
The Gen 3.0 EVERVOLT system is being handled differently.
Effective February 4, 2026, Panasonic transferred operation and monitoring of the Gen 3.0 mobile application to SOLAX USA.
Panasonic has said the app interface may look somewhat different following the transition. Panasonic remains the primary contact for product support and warranty claims.
This is different from the Gen 1.5 system, where the old EVERVOLT System Monitoring app and web portal were discontinued without a replacement cloud monitoring platform.

Are Panasonic Solar and EVERVOLT Warranties Still Valid?
Panasonic says it will continue honoring applicable warranties for its solar and battery products.
The exact warranty depends on the equipment you own, when it was installed, how it was registered, and the warranty program associated with the original installation.
Panasonic has offered several warranty programs over the years, including:
- EVERVOLT AllGuard
- AllGuard
- TripleGuard
- EVERVOLT Home Battery System warranties
- Individual Panasonic solar module warranties
Do not rely on a generic warranty length found on an old solar website. Panasonic’s coverage varies by product and installation. Your original warranty certificate and Panasonic’s current warranty documentation should be used to determine the coverage for your specific system.

Panasonic EVERVOLT Solar Panels
Panasonic’s EVERVOLT solar panels were installed on homes throughout the United States and remain in service even though new Panasonic panels are no longer being sold in the U.S.
If your existing Panasonic panels are operating normally, Panasonic’s decision to exit the solar business does not mean the panels need to be replaced.
Homeowners may still need information about their panels for warranty claims, system expansion, roof work, troubleshooting, or the sale of a home.
EVERVOLT HK2 Black Series
The EVERVOLT HK2 Black Series was one of Panasonic’s high-efficiency residential solar module lines. Its all-black appearance made it popular for residential rooftop installations where both production and appearance were important.
If you have HK2 modules installed on your property, keep your original installation records, module model numbers, serial numbers, warranty documentation, and system plans whenever possible. This information can be valuable if service or a warranty claim is needed later.

EVERVOLT Home Battery
The Panasonic EVERVOLT Home Battery was designed to store energy produced by a solar system for use later in the day or during qualifying power outages.
Existing systems may include several components working together, including the battery, hybrid inverter, SmartBox, current transformers, and monitoring equipment.
If your EVERVOLT battery develops a problem, identifying the exact equipment generation and model number is important because monitoring, troubleshooting, warranty terms, and support procedures can differ between generations.

EVERVOLT Hybrid Inverter
The EVERVOLT Hybrid Inverter manages energy moving between the solar array, battery system, home, and electrical grid.
If an existing EVERVOLT system is experiencing problems, the inverter display and status indicators can provide useful diagnostic information. Panasonic may request photographs of the display, equipment labels, or status lights when troubleshooting a system.
View our archived EVERVOLT Hybrid Inverter specification sheet
EVERVOLT SmartBox
The EVERVOLT SmartBox is part of the energy-management and backup architecture used with compatible EVERVOLT systems. It helps control how energy moves between the home, solar system, battery, and utility grid.
For homeowners troubleshooting an existing SmartBox or EVERVOLT system, we recommend using Panasonic’s current technical documentation rather than relying on older sales literature. Panasonic continues to maintain installation and operating resources for this equipment.
Buying a Home With Panasonic Solar or an EVERVOLT Battery
If you’re purchasing a home that already has Panasonic solar panels or an EVERVOLT battery, don’t be alarmed simply because Panasonic no longer sells new solar equipment in the United States.
Before closing on the property, try to collect:
- Original solar contract
- System plans
- Solar panel model numbers
- Battery and inverter model numbers
- Equipment serial numbers
- Warranty certificates
- Permit and inspection records
- Permission to Operate documentation
- Monitoring information
- Installer contact information
Panasonic states that warranty rights for qualifying Panasonic photovoltaic systems can be transferred to a new homeowner according to the applicable warranty terms.
Panasonic Solar Warranty Transfer Information
Can I Add a New Battery to Panasonic Solar Panels?
Potentially, yes.
Your solar panels and your battery storage system do not necessarily have to come from the same manufacturer.
If you have functioning Panasonic solar panels but want to add battery storage, Synergy Power can evaluate the existing system and determine which current battery options may be compatible.
Important considerations include:
- Existing inverter type
- Age and configuration of the solar system
- Electrical service
- Available equipment space
- Current utility requirements
- Desired backup loads
- Battery capacity
- AC versus DC coupling
There is usually no reason to replace properly functioning solar panels solely because the original manufacturer no longer sells new equipment.
Can I Expand an Existing Panasonic Solar System?
Possibly, but adding panels to an older solar system requires more investigation than simply finding another panel with similar wattage.
The original Panasonic module may no longer be available. Inverter compatibility, roof space, electrical capacity, utility interconnection rules, equipment specifications, and the age of the existing system all need to be considered.
In some cases, adding a separate solar array or battery system may make more sense than modifying the original installation.
Synergy Power can review an existing system and help determine which options are practical.
