Product Usage Instructions
Step 1: Determining Power Requirements
Before using the inverter, it is important to determine the power
requirements of your appliances or tools. This will help ensure that the
inverter’s wattage capacity is sufficient.
To determine the power requirements:
- Identify the highest-wattage appliance or tool that you intend to use with the inverter.
- Turn on the highest-wattage appliance or tool first, and then turn on all other devices in order of highest wattage to lowest.
- If the inverter shuts down due to power overload during this test, you may need a larger capacity inverter or run the devices separately to stay within the inverter’s capacity.
Step 2: Starting Load and Continuous Load
When using motorized appliances or tools, it is important to understand the
starting load and continuous load power requirements. The starting load refers
to the initial surge of power required to start the appliance or tool, while
the continuous load refers to the power required to operate it once started.
To determine the power requirements:
- Check the appliance or equipment for power consumption information, which is usually stamped or printed on the device or provided in the owner’s manual.
- If the information is not indicated, you can calculate the power consumption using the following formulas:
Multiply : AC AMPS X 120 (AC voltage) = WATTS
This formula yields a close approximation of the continuous load of your
appliance.
Multiply : WATTS X 2 = starting load for most appliances
This formula yields a close approximation of the starting load of most
appliances. Note that motorized appliances may have startup loads up to eight
times the rated watts.

WELCOME
Please read this manual thoroughly before installing and operating your new
ECO-WORTHYinverter. This manual contains the information you need to obtain
the performance required for your application. Keep this manual for future
reference. This ECO-WORTHYinverter converts low voltage direct current (DC) to
115 V pure sine wave (PSW) alternating current (AC). The i nverter draws power
from 12 V deep-cycle batteries such as those used for marine, golf cart, and
fork-lift applications, or from other high-current 12 V sources. This model
has been performance tested by ETL and complies with UL and the Canadian
Standards Association safety standards.
A HIGHER-WATTAGE INVERTER MAY BE REQUIRED
To determine whether the power inverter’s wattage capacity is within your
power requirements, turn on the highest wattage appliance first and then all
other devices in order of highest wattage to lowest. This inverter is designed
to automatically shut down in the event of power overload. While running this
test, if the inverter shuts down due to power overload, you may require a
larger capacity inverter or run the devices separately to stay within the
inverter’s capacity.
WARNINGS, CAUTIONS AND NOTES
Any operator and installer of this inverter must read and follow all
WARNINGS, CAUTIONS, NOTES, and all installation and operation instructions. In
particular, comply with WARNINGS (possibility of serious injury or death),
CAUTIONS (possibility of damage to the inverter and/or other equipment), and
NOTES (included to assist you in achieving 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.
- The danger of shock or electrocution treats inverter output the same as commercial AC power.
- Do not use the inverter near flammable materials or in any locations that may accumulate 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 airtemperature should be between – 20°c and 40°c (4°F and 104F) – ideallybetween 15°c and 25 C (60°F and 80°F)
- 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 ECO-WORTHY inverter will only 0perate from a 12v power source. Do not attempt to connect the inverter to any other power source, including any power source.
- Don’t reverse DC input polarity – this will void the warranty.
CATIONS
- Loose connections can result in a severe decrease in voltage that can cause damage to cables and insulation.
- Failure to make the 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 isn’t covered under the Krieger warranty
- Making the connection to the positive terminal may cause a spark as a result of current flowing to charge capacitors within the inverter. This is a normal occurrence.
- Because ofthe possibility of sparking, however, it is extremely important that both the inverter and the 12v battery be positioned from any possible source ofammable fumes or gases Failure to heed this warning could result in fire or explosion.
- Operating the inverter without correctly grounding the unit may result in electric shock.
POWER REQUIREMENTS
When a motorized appliance or a tool turns on, there is an initial surge of
power to start. This surge of power is referred to as the “starting load” or
“peak load.” Once started, the tool or appliance requires less power to
operate. This is referred to as the “continuous load” in terms of power
requirements. You will need to determine how much power your tool or appliance
requires to start up (starting load) and its continued running power
requirements (continuous load). Power consumption is rated in watts, or it can
be calculated from amperes (amps). This information is usually stamped or
printed on most appliances and equipment. If this information is not indicated
on the appliance or equipment, check the owner’s manual.
Multiply : AC AMPS X 120 (AC voltage) = WATTS
This formula yields a close approximation of the continuous load of your
appliance.
Multiply : WATTS X 2 = starting load for most appliances
This formula yields a close approximation of the starting load of most
appliances. Exceptions are motorized appliances such as pumps, freezers, and
air conditioners. These appliances can have startup loads of up to eight times
the rated watts.
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. ECO-WORTHY 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.

CABLE GAUGES
When connecting the inverter to a battery bank use the thickest stranded
insulated copper wire available, in the shortest length practicable.
Recommended cable gauges are as follows:
Model | Description | Recommended Gauges |
---|---|---|
KP1100 | 1100 W POWER INVERTER | 4 AWG (3’/0.9 m included W/ 120 A inline ANL |
fuse)
KP2000| 2000 W POWER INVERTER| 2 AWG (3/0.9 m included W/ 200 A inline ANL
fuse)
HARDWIRE INSTRUCTIONS
This inverter comes equipped with an optional AC output hardwire connection to allow for direction connection to an off-grid electrical panel. All AC wiring (inverter to AC panels, AC panels to circuit breakers, and GFCls) must be rated at the current rating of the fuses and/or circuit breakers. MMulti- strandwire is required. Typically, a 15A circuit breaker requires a 12 AWG wire. Always make sure the unit is completely disconnected from any power source while installing or adjusting any AC output connections. Begin by unscrewing the front plate which is located under the 2 x AC outlets at the front of the inverter. You will then see the 3 connecting terminals, as illustrated below:
SELECT BATTERY TYPE
Select 1 2V “Deep Cycle” battery to receive optimum performance from your power inverter. If connected to a vehicle, boat, or RV, we recommend keeping the engine running while the inverter is in use. If the batteries you connect to the power inverter are not true Deep Cycle batteries, their operational lifetimes may be significantly shortened.
If you are using the same battery bank to power the inverter as well as DC loads, your battery bank will need to be appropriately sized (larger loads will require a battery bank with a larger amp-hour capacity) or the operational lifetimes of the batteries may be significantly reduced.
UNDERSTANDING BATTERY AMP-HOUR CAPACITY WITH YOUR APPLICATION
Determine Total wattage Required:
Add the wattage ratings of all equipment you will connect to your inverter.
Watt-age ratings are usually listed in equipment manuals or on nameplates Your
equipment is rated in amps, multiply that number of AC utility voltage to
estimate watts. (Example: a drill requires 2 . 5 amps. 2 . 5 amps × 120 volts
= 300 watts.
Determine DC BatteryAmps Required
Divide the total wattage required by the nominal battery voltage to determine
the DC amps required. (Example: total wattage required 900 watts: 900 ÷ 12v =
75 DCAmps)
Estimate BatteryAmp- Hours Required
Multiply the DC amps required by the number of hours you estimate you will
operate your equipment exclusively from Batterypower before you have to
recharge your batteries with utility- or generator-supplied AC power.
compensate for inefficiency by multiplying this number by 1 . 2 . This will
give you a rough estimate of how many amp-hours of battery power (from 0ne 0r
several batteries)you should connect to your inverter charger. (Example: 75
DCAmps X 5 Hrs. Runtime X 1 . 2 efficiency Rating = 450Amp – Hours.
NOTE : The type of batteries you use to power your high-power inverter is important. 0perating a high-power will discharge batteries and they will require frequent recharging. Batteries used to start engines are not designed to repeatedly charge and discharge. ECO-WORTHY recommends using “deep-cycle” or “marine” rated batteries.
INSTALLING THE INVERTER
Your ECO-WORTHYinverter should not be mounted under the hood of a vehicle If installing in a vehicle, choose a dry, cool, ventilated area as close to the battery as practical. Before drilling any mounting holes, make sure that there are no wires, fuel lines, or tanks directly behind the surface to be drilled to install the inverter:
- The inverter must be off.
- The inverter should be mounted horizontally to avoid any foreign objects from falling into the inverter from ventilation openings.
- Position the inverter against the mounting surface and mark the locations of the mounting screw openings.
- Remove the inverter and drill four mounting holes.
- Fasten the inverter to the mounting surface using corrosion-resistant fasteners sized #10 or larger.
CONNECTING THE INVERTER
- The inverter must be off.
- Prepare 1 set of positive and negative cables to connect to the battery. Ring terminals are recommended. It is highly recommended to use red cable for the positive terminal and black cable for the negative terminal. The copper cables gauge should be:
LENGTH
| CABLE GAUGE
---|---
1100W| 2000W
<=6’| 4AWG| OAWG
<=10’| 2AWG| 2IOAWG
3. Remove the nuts, washers, and bolts from the positive and negative DC terminals.
4. With the positive cable, connect the ring connector of the positive (red) battery cable to the positive (red) DC terminal (1) of the inverter.
5. With the negative cable, connect the ring connector of the negative (black) battery cable to the negative (black) DC terminal (2) of the inverter.
6. Insert the nuts on both DC terminals and tighten them with washers. Do not over-tighten.
7. Connect the negative (black) battery cable ring terminal to the negative (black) post of the battery (5). Tighten the nut with the washer firmly. Do not over-tighten.
8. Connect the positive (red) battery cable ring terminal to the positive (red) post of the battery (4). Tighten the nut with the washer firmly. Do not over-tighten.
9. Prepare a 14 AWG copper wire with enough length to connect the inverter to the ground. Strip the insulation on both sides. Connect one end of the copper wire to the ground terminal (3) of the inverter, and the other end of the wire to the chassis or ground.
NOTE : If connecting the inverter in a vehicle, connect the copper wire to the chassis of the vehicle, If connecting the inverter in a boat, connect the copper wire to the boat grounding system. If connecting the inverter in a fixed location, connect the copper wire to a ground rod (a metal rod pounded into the earth) or other proper service entrance ground.

- Ensure the appliance to be operated is turned OFF and plug its electrical cord into one of the AC outlets on the front of the inverter.
- Turn the inverter ON.
- Turn the appliance ON.
- Plug in and turn ON additional appliances as needed.
OPERATING A MICROWAVE OVEN WITH YOUR POWER INVERTER
The power rating used with microwave ovens is the “cooking power” which means
the power being “delivered” to the food being cooked. The actual operating
power rating is listed on the back of the microwave. If the operating power
cannot be found on the back of the microwave, check the owner’s manual or
contact the manufacturer.
MORE EFFICIENT USE OF THE BATTERY
Make sure any appliances are energy efficient and turned off after use. Use
LED lighting whenever possible. Wherever possible, charge with solar panels or
wind generators. Do not allow lead acid batteries to remain discharged for
long periods; they lose capacity (amp-hours).
