OPERATION

BEFORE STARTING THE INVERTER

STOP:
BEFORE STARTING THE INVERTER, REVIEW SAFETY SECTION STARTING.

Location Selection
Before starting the inverter, avoid exhaust and location hazards by verifying:

• You have selected a location to operate the inverter that is outdoors and well ventilated.
• You have selected a location with a level and solid surface on which to place the inverter
• You have selected a location that is at least 20 feet ( 6 m) away from any building, other equipment or combustible material.
• If the inverter is located close to a building, make sure it is not located near any windows, doors or vents.

DANGER
Using a generator indoors

CAN KILL YOU IN MINUTES.
Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell

• Avoid other generator hazards.
• READ MANUAL BEFORE USE.

Warning:
Always operate the inverter on a level surface. Placing the inverter on non level surfaces can cause the inverter to tip over, causing fuel and oil to spill. Spilled fuel can ignite if it comes in contact with an ignition source such as a very hot surface.

NOTICE
Only operate the inverter on a solid, level surface. Operating the inverter on a surface with loose material such as sand or grass clippings can cause debris to be ingested by the inverter that could:

• Block cooling vents
• Block air intake system
• Weather – Never operate your inverter outdoors during rain, snow or any combination of weather conditions that could lead to moisture collecting on, in or around the generator.
• Dry Surface – Always operate the inverter on a dry surface free of any moisture.
• No Connected Loads – Make sure the inverter has no connected loads before starting it. To ensure there are no connected loads, unplug any electrical extension cords that are plugged into the control panel receptacles.

NOTICE
Starting the inverter with loads already applied to it could result in damage to any appliance being pow­ered off the inverter during the brief start-up period.

GROUNDING THE INVERTERS
It is recommended to ground the generator with a good lead with in insulated leather in order to prevent the generator from being damaged by electric shock or the wrong use of electricity.

Warning:
Be sure the inverter is properly connected to earth ground before operating.

SERVICE ENVIRONMENT OF THE GENERATOR

• Applicable temperature: -5°C ~ 40°C.
• Applicable humidity: below 95%.
• Applicable altitude: regions below 1500m. (it shall be used by reducing power in regions above l000m)

When actual environmental condition is inconsistent with the condition of output power of the generator set:

1. Every 5°C of increase in ambient temperature will reduce the power of generator by about 2%.
2. Every 30% of increase in relative humidity of air will reduce the power of generator by about 1.5%.
3. Every 1000 feet rising of ASL will reduce the power the generator by about 4.5%.

USE GENERATOR AT HIGH ALTITUDE

1. The density of air at high altitudes is lower than at sea level. Engine power is reduced as the air mass and air-fuel ratio decrease. Output will be reduced approximately 4.5% for every 1000 feet of increased altitude from sea level.
2. At high altitudes increased exhaust emissions can also result due to the increased enrichment of the air fuel ratio. Other high altitude issues can include hard starting, increased fuel consumption and spark plug fouling.
3. The performance of gasoline engines can be improved by replacing the carburetor with a slightly smaller main injector or by adjusting the adjusting screw.If you often use the generator at an altitude of more than 1000 feet, you can buy special high-altitude parts to replace for use. Otherwise, the load power should be reduced to use the generator.
4. Even with the suitable carburetor, a 1000 feet rise in altitude reduces petrol engine power by about 4.5%. Without the replacement of a suitable carburetor, this decline would be even greater.

NOTICE
If a carburetor suitable for high altitude use is fitted to a gasoline engine for low altitude use, too thin mixture will reduce the power output of the gasoline engine, cause overheat or even serious damage.

CONNECT TO HOUSEHOLD POWER SUPPLY

1. When the generator is connected to household power source as a backup power supply, the connection shall be carried out by a professional electrician or a person familiar with electricity.
2. After connecting the load to the generator, check carefully whether electrical connection is safe and reliable.
3. Improper electrical connection may cause generator damage, burning or fire.
4. Avoid connecting this generator to commercial power outlet.
5. When extending the cable, be sure not to exceed its length.
6. The appearance of extension cable shall be protected by a layer of tough and elastic rubber cover (IEC25) or other substitutes.

GENERATOR CAPACITY

• Make sure before starting the generator. The total power of the load apparatus (the sum of resistive, capacitive and inductive load) shall not exceed the rated power of the generator.
• Make sure the generator can supply enough continuous (running) and surge {starting) watts for the items you will power at the same time. Appliance and power tool manufacturers usually list rating information near the model or serial number.

NOTICE

• Do not overload the generator’s capacity. Exceeding the generator’s wattage/amperage capacity can damage the generator and/or electrical devices connected to it.
• If more than one load or electrical equipment is connected to the generator set, remember that the one with the highest starting load is connected first, and the one with the lowest starting current is connected last.

TO DETERMINE POWER REQUIREMENTS:

1. Select the items you will power at the same time.
2. Total the continuous (running) watts of these items. This is the amount of power the generator must produce to keep the items running.
3. Estimate how many surge (starting) watts you will need. Surge wattage is the short burst of power needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator. Because not all motors start
   at the same time, total surge watts can be estimated by adding only the item(s) with the highest additional surge watts to the total rated watts from step.

Example:

Total Running Watts

|

2000

Highest Starting Watts| + 750
Total Starting Watts Needed| 2750

• Wattages listed are approximate. Verify electrical appliances actual wattage.

In general, capacitive and inductive load, especially motor drive device, produce a large starting current when starting up. The following table is for your reference when you connect these electrical appliances to the generator set.
