PV1000HF
PV1800HF
Connect your Inverter to your batteries using the following procedures—always loosely twist each pair of cables
(one positive and one negative) together:
Connect DC Wiring
Connection to Two DC Terminals
PV1000HF and PV1800HF models 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.
