IMPORTANT SAFETY WARNINGS

PLEASE READ ALL INSTRUCTIONS AND CAUTIONARY MARKINGS ON

THE UNIT AND THIS MANUAL BEFORE USING THE INVERTER. STORE

THIS USER MANUAL WHERE IT CAN BE ACCESSED EASILY.

WARNING: Only an authorized EverVolt technician with appropriate

contracting license(s) should attempt to service the EverVolt. Please

consult your local codes and standards for required qualifications to

install and service an energy storage system.

Safety Symbols

WARNING. This indicates the risk of electric shock. The

presence of high voltage levels may constitute a risk of injury

or death to users and/or installers.

CAUTION. This indicates important information where failure

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.

General Inverter Precautions

CAUTION. Before installing and using this inverter, read all

instructions and cautionary markings on the inverter and

all appropriate sections of this guide. This inverter must be

installed by licensed electricians only.

CAUTION. Normally grounded conductors may be

ungrounded and energized when a ground fault is indicated.

CAUTION. This inverter is heavy. It should be lifted by at least

two persons for safety.

CAUTION. To reduce risk of fire hazard, do not cover or

obstruct the cooling fan.

CAUTION. Do not operate the Inverter if it has received a

sharp blow, been dropped, or otherwise damaged in any way.

If the Inverter is damaged, contact Panasonic for an RMA

(Return Material Authorization).

Important Safety Warnings

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.

Important Safety Warnings

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.

To ensure optimal reliab

lity and to meet warranty

requirements, the Inverter must be installed and/or stored

according to the instructions in this guide.

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.
