Panasonic Solar & EVERVOLT Battery Support

Panasonic has discontinued its solar panel and battery storage business in the United States.

However, existing Panasonic solar panels and EVERVOLT battery systems can still receive support.

If you own Panasonic solar panels, an EVERVOLT battery, hybrid inverter, or SmartBox, this page explains:

Synergy Power previously installed Panasonic solar and energy storage equipment.

Although we no longer sell new Panasonic systems, we want existing owners to have a clear place to find support information.

Is Panasonic Still Selling Solar Panels and Batteries?

No. Panasonic has announced that it is discontinuing its solar and battery storage business in the United States.

However, the company has said it will continue supporting:

Existing customers
Systems still going through commissioning
Applicable warranty claims

In addition, Panasonic says warranties for installed products and qualifying products awaiting installation will continue under the applicable terms.

For existing owners, this means the end of new equipment sales does not automatically end warranty coverage.

What Happened to the EVERVOLT App?

The answer depends on which EVERVOLT battery system you own.

Specifically, Panasonic made different changes for:

EVERVOLT Gen 1.5
EVERVOLT Gen 3.0

EVERVOLT Gen 1.5 Monitoring App Discontinued

Panasonic discontinued the EVERVOLT System Monitoring mobile app and web portal used with Gen 1.5 battery systems.

Affected models include:

EVAC-105-4/6
EVDC-105-4/6

As a result, the old app and web portal are no longer available for download, use, or support.

However, the battery system itself can still operate without the app.

These changes affect remote monitoring and some configuration features, rather than stopping the battery hardware from working.

How Do I Monitor a Gen 1.5 EVERVOLT Battery Now?

Panasonic directs Gen 1.5 owners to use the LCD display on the battery system.

For example, the display can show:

Battery state of charge
Current system status
Basic operating information
Alarm information

However, some advanced settings require a direct laptop connection to the inverter.

Such settings and functions may include:

Battery reserve settings
Charging settings
Discharging settings
Firmware functions

Even with access to the LCD display, Gen 1.5 owners can no longer view the app’s historical daily energy graphs remotely.

What About the myEVERVOLT App for Gen 3.0 Systems?

By comparison, Gen 3.0 systems follow a different monitoring arrangement.

Effective February 4, 2026, Panasonic transferred operation and monitoring of the Gen 3.0 mobile app to SOLAX USA.

As a result of this transition, the app may look different.

However, Panasonic remains the main contact for:

Product support
Warranty claims

Unlike Gen 3.0, Gen 1.5 systems lost their monitoring app and web portal 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.

However, your exact coverage depends on:

The equipment you own
When it was installed
How it was registered
The warranty program that applied to your installation

Panasonic has offered several warranty programs over the years, including:

EVERVOLT AllGuard
AllGuard
TripleGuard
EVERVOLT Home Battery System warranties
Individual solar module warranties

Because coverage varies, use your original warranty certificate and Panasonic’s current warranty documents to confirm the terms for your system. A generic warranty length on an older solar website may not apply.

Panasonic EVERVOLT Solar Panels

Panasonic EVERVOLT solar panels remain installed on homes across the United States.

However, the company’s decision to stop selling new panels does not mean existing panels need to be replaced.

If your solar panels are working normally, they can continue operating.

Even so, keep your system information available for:

Warranty claims
Roof work
Troubleshooting
System expansion
Selling your home

EVERVOLT HK2 Black Series

The EVERVOLT HK2 Black Series was one of Panasonic’s residential solar panel lines.

Its all-black appearance made it popular for rooftop installations where both energy production and appearance mattered.

To prepare for future service needs, keep as much original documentation for your HK2 panels as possible.

Useful records include:

Panel model numbers
Serial numbers
Original installation documents
Warranty documents
System plans

With these records on hand, you can provide equipment details when requesting service or filing a warranty claim.

EVERVOLT Home Battery

The Panasonic EVERVOLT Home Battery was designed to store electricity for use later in the day or during qualifying outages.

An existing EVERVOLT system may include:

Battery modules
Hybrid inverter
SmartBox
Current transformers
Monitoring equipment

If your battery system develops a problem, first identify the exact generation and model number.

That distinction matters because generations may differ in:

Monitoring systems
Troubleshooting steps
Warranty terms
Support procedures

View our archived EVERVOLT Home Battery specification sheet

EVERVOLT Hybrid Inverter

The EVERVOLT Hybrid Inverter manages electricity moving between:

Solar panels
Battery storage
Home electrical circuits
Utility grid

If your EVERVOLT system has a problem, the inverter display may provide useful information.

When you contact support, Panasonic may ask for:

Photos of the display
Equipment labels
Status lights
Error or alarm information

View our archived EVERVOLT Hybrid Inverter specification sheet

EVERVOLT SmartBox

The EVERVOLT SmartBox is part of the energy-management and backup system used with compatible EVERVOLT equipment.

It helps control how electricity moves between:

Home electrical circuits
Solar equipment
Battery storage
Utility grid

If you are troubleshooting a SmartBox or EVERVOLT system, use Panasonic’s current technical documents instead of older sales materials.

For this purpose, Panasonic continues to maintain installation and operating resources for the equipment.

Buying a Home With Panasonic Solar or an EVERVOLT Battery

If you are buying a home with Panasonic solar panels or an EVERVOLT battery, do not assume the system is unsupported simply because Panasonic stopped selling new solar equipment.

Before closing, try to collect:

Original solar contract
System plans
Solar panel model numbers
Battery model number
Inverter model number
Equipment serial numbers
Warranty certificates
Permit records
Inspection records
Permission to Operate documents
Monitoring information
Installer contact information

In addition, Panasonic states that warranty rights for qualifying photovoltaic systems may transfer to a new homeowner under the applicable terms.

Panasonic Solar Warranty Transfer Information

Can I Add a New Battery to Panasonic Solar Panels?

Potentially, yes.

Your solar panels and battery do not always need to come from the same manufacturer.

For example, if your Panasonic panels are still working, Synergy Power can review the system to determine which current battery options may be compatible.

During that review, important factors include:

Existing inverter type
Solar system age
System configuration
Electrical service
Available equipment space
Current utility rules
Desired backup loads
Battery capacity
AC or DC coupling

In general, there is no need to replace properly working solar panels solely because the manufacturer stopped selling new ones.

Can I Expand an Existing Panasonic Solar System?

Possibly. However, adding panels to an older system requires more review than simply finding a panel with similar wattage.

Important questions include:

Are the original Panasonic panels still available?
Is the existing inverter compatible?
How much roof space is available?
Does the electrical system have enough capacity?
What do current utility rules allow?
Has the system’s age affected the expansion options?
Will new equipment work properly with the old equipment?

In some cases, a separate solar array or battery system may make more sense than changing the original installation.

Synergy Power can review the existing equipment and help determine which options are practical.
