Cable Gauges

Note:

The type of batteries you use to power your high power inverter is important. Operating a high-power inverter will routinely discharge batteries and they will require frequent recharging. Batteries used to start engines are not designed to repeatedly charge and discharge. Energizer® recommends using “deep-cycle” or “marine” rated batteries.

When connecting the inverter to a battery bank use the thickest stranded insulated copper wire available, in the shortest length practical. Recommended cable gauges are as follows:

Energizer®	Recommended Gauges
Model #
EN500	12AWG (3 ft. included)
EN900	8AWG (3 ft. included)
EN1100	8AWG (3 ft. included)
EN1500	4AWG (not included)
EN2000	2AWG (not included)
EN3000	0AWG (not included)
EN4000	0AWG (not included)

WARNING:

DANGER OF BATTERY EXPLOSION – INSTALL A FUSE

Battery banks can deliver very high levels of current that can vaporize metal, start fires and cause explosions. Energizer® recommends installing one ANL type fuse and fuse holder close to the positive battery bank terminal. This fuse protects the batteries from accidental DC cable shorts, which can cause batteries to explode. ANL fuses and fuse holders are available at most marine supply stores.

CAUTIONS:

•Loose connections can result in a severe decrease in voltage that can cause damage to cables and insulation.

•Failure to make correct polarity ( Pos, Neg ) connection between the inverter and the battery bank can result in blowing fuses in the

inverter and can permanently damage the inverter. Damage caused by reversed polarity is not covered under the Energizer® warranty.
