Welcome
Please read this manual thoroughly before installing and operating your new Enerwatt Power
Inverter. This manual contains information you need to obtain the performance required for
your application. Keep this manual for future reference.
This Enerwatt Inverter converts low voltage, direct current (DC) to 110 volt modified Sine
wave (MSW) alternating current (AC). The inverter draws power from 12 volt deep-cycle
batteries such as those used for marine applications, golf cart, and fork-lift or from other high
current 12 volt sources.
This model, EW-1100 / EW-2000, has been performance tested by MET and complies with
Underwriter’s Laboratories and Canadian Standards Association safety standards.
A Higher Wattage Inverter May Be Required
To determine whether the Enerwatt EW-1100 / EW-2000 will operate a particular appliance or
a combination of appliances, run a test. All inverters are designed to automatically shut down
in the event of a power overload. This protection feature prevents damage to the unit while
running appliances with combined wattages below the 1100 / 2000 watt range. Turn on the
highest wattage appliance first then other appliances (one after the other). If an appliance
combination in the 1100 / 2000 watt range does not operate properly, then it is likely that this
Enerwatt inverter does not have the required capacity to operate the appliance(s) in question.
WARNINGS, CAUTIONS AND NOTES
It is very important that any operator and installer of this inverter read and follow all WAR-
NINGS, CAUTIONS AND NOTES and all installation and operation instructions. In particular,
comply with WARNINGS (possibility of serious injury or death), CAUTIONS (possibility of da-
mage to the inverter and / or other equipment), and NOTES (included to assist you in achie-
ving the maximum performance and longest working life from this advanced-design inverter).
WARNINGS: INVERTER OUTPUT
This is a heavy-duty device that produces voltages similar to commercial AC power.
•
Danger of shock or electrocution - treat inverter output the same as commercial AC power.
•
Do not use the inverter near flammable materials or in any locations that may accumu-
late flammable fumes or gases. This is an electrical device that can briefly spark when
electrical connections are made or broken.
•
Do not allow water or other liquids to contact the inverter.
•
Do not use appliances with damaged or wet cords.
CAUTIONS: INVERTER OPERATING ENVIRONMENT
•
Surrounding air temperature should be between 4 °F and 104 °F (-20 °C and 40 °C) –
Ideally between 60 °F and 80 °F (15 °C and 25 °C).
•
Keep the inverter away from direct sunlight if at all possible.
•
Keep the area surrounding the inverter clear to ensure free air circulation around the
unit. Do not place items on or over the inverter during operation. The unit will shut
down if the internal temperature gets too hot. Restart the inverter after it cools.
•
This Enerwatt inverter will only operate from a 12 V power source. Do not attempt to
connect the inverter to any other power source, including any AC power source.
•
Do not reverse DC input polarity – this will systematically void the warranty.
