to comply may result in safety hazards or cause damage to
this product.
CAUTION. This indicates the risk of a hot surface. The surface
may reach a temperature high enough to cause serious burn
injuries.

Installation Manual
CAUTION. Under high temperature environment, the cover
of this inverter could be hot enough to cause skin burns if
accidentally touched. Ensure that this inverter is away from
normal traffic areas.
WARNING. These servicing instructions are for use by
qualified personnel only. To reduce the risk of electric shock,
do not perform any servicing other than that specified in the
operating instructions unless you are qualified to do so.
WARNING. Authorized service personnel should reduce the
risk of electrical shock by disconnecting AC, DC and battery
power from the inverter before attempting any maintenance
or cleaning or working on any circuits connected to the
inverter. Turning off controls will not reduce this risk.
Internal capacitors can remain charged for five (5) minutes
after disconnecting all sources of power.
WARNING. Do not disassemble this inverter yourself. It
contains no user-serviceable parts. Attempting to service this
inverter yourself may cause a risk of electrical shock or fire
and will void the warranty from the manufacturer.
WARNING. To avoid a risk of fire and electric shock, make
sure that existing wiring is in good condition and that the wire
is not undersized. Do not operate the Inverter with damaged
or substandard wiring.
WARNING. During the installation process, drilling, punching,
and screwing the bolts can cause metal burrs, which must be
cleaned up to prevent them from falling into the electronics.
WARNING. Use only recommended accessories.
WARNING. Exposed hazardous voltage, during servicing or
for emergency procedures use a lockable manual breaker
lockout on the main service panel disconnects to enable
Lock-Out-Tag-Out per the Standard for Electrical Safety in
the Workplace, NFPA 70E, and the Standard for Workplace
Electrical Safety, CSA Z462, and any other local codes and
standards relevant to your jurisdiction.

Installation Manual
WARNING. Charge EverVolt only within the specified
conditions (e.g. temperature range, voltage, current, etc.)
Failure to do so may result in damages, heat generation,
smoke, fire, or explosion.
Check the positive (+) and negative (-) terminals. If EverVolt
is connected with reversed polarity, unexpected reactions
may occur such as damages, heat generation, smoke, fire, or
explosion.
Do not connect between the positive (+) and negative (-)
terminals with a conductive material (e.g. wire, a cable, etc.).
This may result in damages, heat generation, smoke, fire, or
explosion.
Do not directly solder the EverVolt. This may result in
damages, heat generation, smoke, fire, or explosion.
WARNING: Risk of electric shock. Risk of fire. Do not attempt
to repair the battery(ies); it contains no user-serviceable
parts. Tampering with or opening the battery(ies) will void
the warranty. If the battery(ies) fails, contact Panasonic at
panasonicbatterys[email protected]
WARNING: Proper disposal of lithium-ion batteries is
required. Please contact your Panasonic representative for
disposal and recycling measures.
WARNING: Take care when lifting the Battery. The Battery is
heavy and may require a lifting tool to initially lift the battery
high enough to get a good hold on it.
Important Safety Warnings

8 Installation Manual
WARNING: Only an authorized technician should attempt to
service the EverVolt.
WARNING: Risk of injury and equipment damage. Protect the
EverVolt from damage and improper use.
WARNING - ARC FLASH AND SHOCK HAZARD: Appropriate
PPE and Tools Required while working on this energized
equipment.
INVERTER WARNINGS: Method of active anti-islanding
protection: The Inverter monitors for sudden changes in the
impedance of the grid by looking for changes in the second to
the eighth harmonic.
Perform installation and wiring in accordance with all
applicable local electrical codes and standards.
Protection against lightning and resulting voltage surge must
be in accordance with local standards.
Using unapproved attachments or accessories could result in
damage or injury.
Use Class 1 wiring methods for field wiring connections to
terminals of a Class 2 circuit. Use only 6-8 AWG (2.5mm2
to 4mm2) and 1/0 wire in the junction box terminal block.
Select the wire size based on the protection provided by the
circuit breakers / fuses. Install properly rated over-current
protection as part of the system installation.

Important Safety Warnings

10 Installation Manual
In Case of Fire or Other Emergency
In all cases:
• If safe to do so,
1. Initiate Rapid Shutdown and allow the DC voltage to drop to a
safe level
2. Power down inverter, and
3. Disconnect wiring sources of AC and DC power
• Contact the fire department or other required emergency response
team.
• Evacuate the area.
In case of fire:
• When safe, use a fire extinguisher. Suitable types are A, B, and C dry
chemical fire extinguishers. Additional extinguishing media include
water, carbon dioxide, or alcohol-resistant foams.
In case of flooding:
• Stay out of water if any part of the system or wiring is submerged.
• If possible, protect the system by finding and stopping the source of
the water, and pumping it away.
• If submerged, the whole system may need to be replaced.
• Let the area dry completely before use.
In case of unusual noise, smell or smoke:
• Ensure nothing is in contact with the system or in the venting area on
