10,000 Watt AC Inverter by Wagan Tech

User’s Manual—Please read before using this equipment.

4. Connect the fuse holders to the short positive (+) cable terminals.

5. Wrap the inverter positive cable ends with insulating plastic wrap.

6. Mount the fuse holders to a support structure.

7. Install fuses in the fuse holders and tighten the retaining nuts.

8. Install the Ground wire from the inverter enclosure to the grounding point.

WARNING: THE PROCEDURE THAT FOLLOWS IS FOR SAFE CONNECTION TO MINIMIZE

INITIAL CONNECTION SPARKING AND DAMAGE FROM UNPROTECTED BATTERY CABLE

SHORTS.

Making the ﬁrst connection between the positive cable and the inverter’s positive terminal

may cause a spark. This is a normal and is a result of capacitors in the inverter starting to

charge. Because of the possibility of sparking, it is extremely important that both the inverter

and the battery bank be positioned away from any source of ﬂammable fumes or gases.

Failure to heed this warning can result in ﬁre or explosion. Do not make the ﬁrst positive

terminal connection immediately after batteries have been charging. Allow time for the

battery gasses to vent to outside air.

Inverter to Battery Connection Procedure

1. Disconnect any Remote Switch Connector from the front panel of the inverter.

2. Make sure the ON/OFF switch located on the front panel of the inverter is in the

OFF position.

3. Install all non-fused (negative) cables from the negative battery bank terminal to the

Negative (−) Terminals on the rear of the inverter.

4. Tighten the retaining nuts.

5. Connect all fuses end positive cable ring terminals to the positive battery bank

terminal.

6. Carefully tighten the retaining nuts. DO NOT SHORT BATTERY POSITIVE TO

NEGATIVE OR GROUND.

7. At the inverter end carefully unwrap one positive cable end and connect it to one

Positive Terminal. A spark is likely to result. This is normal.

8. Tighten the retaining nut. BE CAREFUL; DO NOT SHORT THE POSITIVE TERMINAL

TO THE GROUNDED INVERTER ENCLOSURE.

9. Continue installing the remaining positive cables.

10. Turn ON the inverter. The display on the front panel should show between 10.5 to

15 volts depending on the voltage of the power source. When the voltage reading

does not fall within this range, check the connections of the wires to the terminals

on the power source and the inverter to make sure they are secure. Also check the

voltage of the power source. Make certain that the High Temp or Overload LED

Indicators are not lit.

11. Turn OFF the inverter. The Overload and Over Temp LEDs may brieﬂy “ﬂash”. This

is normal. The audible alarm may also emit a short “chirp”. This is also normal.

12. When you have conﬁrmed that the appliance to be operated is turned off, plug the

appliance into one of the AC Outlets on the front panel of the inverter.

13. Turn the inverter on.

Note: If an extension cord is used from the inverter to an appliance, limit the extension cord

length to 50 feet or less. Make sure that the cord is properly rated to carry the appliance

load. Extension cords are not to be used as permanent wiring. Instead, use High Output

Terminals and NEC compliant wiring, outlets and installation techniques.

CHARGING THE BATTERY BANK

It is not the purpose of this Inverter User’s Guide to provide detailed information regarding

battery charging systems. However, the user should try to supplement any charging system

with either wind or solar power. These can continue to operate during power outages and

they also reduce recharge time. If automatic AC powered battery chargers do not provide

enough charging current for a larger battery bank, is permissible to have two automatic

battery chargers connected to the same battery bank.

REGULAR LOSS OF COMMERCIAL POWER

If an inverter system is used during commercial power outages that occur daily, conﬁgure

the charging system to replace energy during the time that commercial power is available.

Replacement of battery energy always requires more than was taken from the battery

(typically 130 percent). In the example used earlier in this document, the AC load ran for 10

hours. If commercial power is available, there are approximately 14 hours left in the day to

do the recharging. The following is an example of what is necessary to recharge a battery

bank that has 16,500 AH of capacity (as in the example above) and has been discharged to

10.5 volts (discharged). The charger has to replace 2145 AH (1650 × 1.3 AH) in 14 hours.

So the charger must charge at a rate of 153 amps for 14 hours. As this charge current is

distributed among the batteries in the battery bank, the current received by an individual

battery is within its charge rating. Be sure that the battery is well vented as the area will

likely have accumulations of an explosive mixture of hydrogen and oxygen. Follow all

recommendations for use that are contained in the battery charger manual.

WARNING: THERE IS DANGER OF EXPLOSION. DO NOT CONNECT OR DISCONNECT

CHARGER CABLES DIRECTLY AFTER BATTERY DISCHARGE OR RECHARGE—MAKE SURE THAT

THE BATTERY BANK AREA IS WELL VENTED BEFORE ATTACHING OR REMOVING CABLES.

If ﬂooded lead acid batteries are used, as examples given in this document, be sure that

periodic checks of battery electrolyte levels are accomplished. Follow battery manufacturer’s

instructions in keeping the electrolytes at the proper level. Be sure to use pure distilled water

when replacing evaporated electrolyte liquid.
