Battery Connection

Connect your Inverter to your batteries using the following procedures—always loosely twist each pair of cables (one positive and one negative) together:

models, it is acceptable to

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 posi- tive 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.

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 volt- age drop and allows for maximum transfer of current. Your Inverter is capable of deliv- ering peak wattage at up to 200% of its rated continuous wattage output instantaneously. See Specifications page for details. Heavier

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.

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. If polarity is reversed, the Inverter’s 40-amp internal fuses will blow. To access internal fuses, disconnect all equipment and batteries from the Inverter. Then, unscrew and remove front panel; slide out bottom panel to access fuses. Replace blown fuses with an equal number of new fuses of the same type and amperage. Replace front panel and screws.

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.
