Battery Bank Diagram

The diagram below shows an inverter with up to four sets of connections to a battery bank

with recommended fuses for battery protection.

INSTALLATION—CONNECTING AN INVERTER

General Information

This inverter must be mounted in a dry, cool and dust free environment.

If installation is on a wall or bulkhead, the inverter should be mounted horizontally. Vertical

mounting allows dust and objects to fall into inverter vents.

Loose cable connections can result in a severe voltage drop that can damage connectors,

conductors, and insulation and can cause sparking. A reverse polarity connection will blow

fuses in the inverter and can permanently damage the inverter. Damage caused by reverse

polarity will void the warranty.

There are multiple sets of DC input terminals to reduce the need for larger gauge cables. All

DC terminals are threaded studs that have metal washers and nuts. Make sure that you have

the proper sized socket wrenches to tighten terminal connections when so directed. The table

below indicates the how many sets of cable terminals to use for different power levels. One

terminal set is any positive and any negative terminal.

NOTE: No single terminal can carry more current than described in the table that follows:

Watts 2500 5000 7500 10000

Terminal Sets 1 2 3 4

All cables must be made of stranded, insulated copper wire. Measure the round trip length

of cable needed. Round trip is the distance from the negative battery bank terminal to the

inverter and back to the positive terminal of the battery bank. Use a length of string and

follow the route the cables will follow. Measure the length of string and then determine the

correct gauge cable required for the power level and total distance. Appendix A has a table

that relates cable length and gauge for your inverter. Measure all terminal stud diameters

that are to be connected to cables. Obtain ring terminals that ﬁt the cables and terminal

studs. Be sure the ring terminals can carry the current required.

Ground Terminal Wire Requirements

Use a minimum of 6 gauge stranded wire for enclosure ground wire. Connect this to the

chassis of your vehicle or to the grounding system in your boat. In a city, the ground wire

can connect to a metal cold water pipe that goes underground. In remote locations, the

ground wire can be connected to an “earth ground”. This can be an attachment to a 6 foot

long copper clad metal rod driven into the ground. In the unlikely event of a short circuit,

operating the inverter without proper grounding can result in electrical shock. Do not directly

connect this ground to the negative terminal on the inverter.

Cable Preparation

1. Strip all cable ends to allow crimping of Ring Terminals.

2. Crimp appropriate sized ring terminals onto all cable ends including fuse holder

cable ends.

3. Connect the fuse holders to the long positive (+) cable terminals.

Fusing Requirements

NOTE: It is important that any high powered DC system has main battery fuses in all positive

(+) battery cables within one foot of the battery bank’s positive terminal. The fuses protect

against battery explosion if a battery cable accidentally shorts. The fuse amperage rating

must be sized to allow simultaneous operation of all the AC appliances to be powered,

allowing for momentary high start-up current requirements. Use the recommended ANL type

fuses and fuse holders (or equivalent) are recommended. See Appendix A for recommended

fuse ratings. They are readily available from marine supply dealers. Read and comply with

the warning below.

WARNING: EXPLODING BATTERIES CAN SPRAY MOLTEN LEAD, HOT SULFURIC ACID AND

PLASTIC FRAGMENTS. BATTERIES THAT ARE CHARGING OR UNDER HIGH DISCHARGE RATES

CAN PRODUCE EXPLOSIVE HYDROGEN GAS INTO THE SURROUNDING AREA. BE SAFE—

FUSE THE BATTERY BANK AND MAKE SURE THE BATTERY BANK LOCATION IS PROPERLY

VENTILATED.

DC Cable Gauge

Minimize cable losses by using the thickest insulated stranded copper wire available, and

the shortest practical length. Refer to Appendix A at the rear of this manual for suggested

cable gauge.
