Ground Terminal

This connection is located on the lower left of the rear panel. It is for attaching a 6 gauge

insulated safety ground wire. This safety wire is for protecting personnel if there is an

unlikely failure in either the cabling or enclosure insulation. Do not directly connect this

ground connection to the negative DC terminal. This safety wire is to be connected to the

vehicle frame or earth ground. This is described in the installation procedure.

PLANNING THE INVERTER SYSTEM

Any large wattage inverter system requires planning before installation. There are several

steps to the planning process so the user must determine the following:

• Maximum inverter wattage required

• Operating time (run time) needed between battery recharges

• Battery bank capacity in amp-hours

• Charger requirement to charge batteries within a practical time.

• Distance between battery bank and inverter.

DETERMINING MAXIMUM APPLIANCE WATTAGE

Maximum AC appliance wattage is the ﬁrst factor in planning battery and charging systems.

Some background: Large microwave oven speciﬁcations list cooking power (watts) and

appliance power. Appliance power is the AC load the inverter has to supply.

Most other electrical tools, appliances and audio/video equipment have labels that list the

unit’s power requirements in watts. If the tool or device is rated in amps, multiply the amps

by 115 (115V AC) to determine the watts. For example, a power tool rated at 4 amps will

draw 460 watts.

Determine the wattage of each appliance you need to simultaneously operate. Add all of

the appliance wattages to obtain an estimated “total watts” number. Remember to consider

the startup surge that motorized appliances will cause. Do not exceed the surge rating of this

inverter (6000 watts). This can cause immediate an overload shutdown.

At 3,000 watts continuous output, this inverter requires a DC power supply (battery bank)

that can continuously supply the following level of amps for the duration of the run time:

#2007-2 (12V DC Input) — 300 amps @ 12V

#2007-4 (24V DC Input) — 150 amps @ 24V

#2007-8 (48V DC Input) — 75 amps @ 48V

CONFIGURING THE BATTERY BANK

To determine the minimum battery ampere-hour rating that you will need to operate

appliances from the inverter, and any DC appliances powered by the battery bank. Follow

these steps:

(The following calculations are speciﬁc to 12V systems. For 24V or 48V systems, a different

calculation is required but the same principles should apply)
