include two DC terminals;
PV3000HF models
include four DC terminals
(two positive and two
negative). For PV3000HF
models, it is acceptable to
use only one set of cables
to connect your battery to
only one positive and one
negative DC terminal,
however, your PV3000HF
may provide reduced output power. It doesn’t
make a difference which positive and negative
terminal you choose for the connection
because both positive terminals are internally
bonded and both negative terminals are also
internally bonded.
Regardless of the model, you must run
positive cable(s) through user-supplied
UL-listed fuse(s) and fuse block(s) of the
proper size: PV1000HF—175 amp fuse,
PV1800HF—250 amp fuse, PV3000HF—500
amp fuse.
See Specifications page for Minimum Recommended Cable Sizing
Chart. An excellent source of cables are battery jumper cables.
Output performance will decrease if you use only one jumper
cable.
Connection to Four DC Terminals
To obtain maximum
output power from
PV3000HF models, it is
recommended (but not
required) that you use
four 00 gauge cables to
connect your battery to all four DC
terminals. In this connection you must run
two positive cables of equal length through
two user-supplied UL-listed 250-amp fuses
and fuse blocks. Use the equivalent of two
00 cables in all other connections within the
battery system.
Length & Gauge of Cables
Although your Inverter is a high-efficiency
converter of electricity, its rated output
capacity is limited by the length and gauge
of the cabling running from the battery to
the unit. Use the shortest length and largest
diameter cabling (maximum 00 gauge) to fit
your Inverter’s DC Input terminals. Shorter
and heavier gauge cabling reduces DC
voltage drop and allows for maximum
transfer of current. Your Inverter is capable
of delivering peak wattage at up to 200% of
its rated continuous wattage output
instantaneously. See Specifications page for
details. Heavier gauge cabling should be
used when continuously operating heavy
draw equipment under these conditions.
Tighten your Inverter and battery terminals
to approximately 3.5 Newton-meters (2.58
foot lbs.) of torque to create an efficient
connection and to prevent excessive heating
at this connection. Insufficient tightening of
the terminals could void your warranty.
•ConnectGround:Using a #8 AWG wire
or larger, directly connect the Main Ground
Lug to the vehicle's chassis ground or earth
ground. See Feature Identification section to
locate Main Ground Lug. All installations
must comply with national and local codes
and ordinances.
• Connect Fuse: In addition to the
protection provided by the Inverter’s
internal fuses, NEC article 551 requires that
you connect your Inverter’s positive DC
Terminal(s) directly to a UL-listed fuse(s)
and fuse block(s) within 18 inches of the
battery. See diagrams below for proper fuse
placement.
Battery Connection
Vehicular
Your Inverter’s Nominal DC Input Voltage must match the voltage of your battery or batteries—12 Volts in most vehicular applications. It is possible
to connect your Inverter to the main battery within your vehicle’s electrical system. In many vehicular contexts, the Inverter will be connected to
one or more dedicated auxiliary (house) batteries which are isolated from the drive system to prevent possible draining of the main battery.

12 Volt Main and Auxiliary (House) Battery Connection (Isolated Parallel)—two DC terminals
Connect your Inverter to your batteries using the following procedures—always loosely twist each pair of cables (one positive and
one negative) together:
WARNING! Never attempt to operate your Inverter by connecting it directly to output from an alternator rather than a
battery or battery bank.
CAUTION! Observe proper polarity with all DC connections. Reversed polarity will cause internal damage to your Inverter.
PV3000HF
Note: Connection to all four DC terminals
is recommended to provide the maximum
output power from PV3000HF models.
