Rechargeable Devices

CAUTIONS
• Some rechargeable devices are designed to be charged by plugging them directly into an AC receptacle. These
devices may damage the inverter or the charging circuit.
• When using a rechargeable device with your inverter, monitor its temperature for the initial ten minutes of use to
determine if it produces excessive heat. If excessive heat is produced, the device should not be used with your
inverter.
• This problem does not occur with most battery-operated appliances and tools. Most of these appliances use a
separate charger or transformer that is plugged into an AC receptacle.
• Your inverter is capable of running most chargers and transformers.

POWER SOURCE AND PROTECTIVE FEATURES

Power Source Requirements

Your inverter will operate from input voltages between 11 and 15 volts DC. If the voltage drops below 10.5 volts,
an audible low battery warning alarm will sound. If the input voltage drops below 10 volts DC, the inverter will shut
down. This feature protects the battery from being completely discharged.
The inverter will also shut down if the input voltage exceeds 15 volts. This protects the inverter against excessive
input voltage. Although the inverter has built-in protection against over voltage, it may still be damaged if the input
voltage exceeds 15 volts.
Your inverter is engineered to be connected directly to standard electrical and electronic equipment in the manner
described in the "Installation" section of this Instruction Manual. Do not connect the inverter to household or RV AC
distribution wiring. Do not connect the inverter to any AC load circuit in which the neutral conductor is connected to
ground (earth) or to the negative of the DC (battery) power source.
The inverter will operate most AC loads within its power rating. Some induction motors used in refrigerators,
freezers, pumps and other motor-operated equipment, require very high surge currents to start them. The inverter
may not be able to start some of these motors even though their rated current draw is within specifications for this
power inverter. If a motor refuses to start, observe the battery voltage using a DC voltmeter while trying to start the
motor. If the battery voltmeter drops below 11 volts while the inverter is attempting to start the motor, this may be
why the motor won't start. Make sure the battery connections are tight and the battery (or batteries) is (are) fully-
charged. If the connections are good and the battery is charged, but the voltage still drops below 11 volts, you may
need to use a larger battery (or battery combination).
Inductive loads, such as TVs and stereos, require more current to operate than resistive loads of the same wattage
rating. Induction motors, as well as some TVs, may require two to six times their rated wattage to start up. Because
these inverters have a peak watt power rating, many such appliances and tools may be safely operated. The
equipment that needs the highest starting wattage are pumps and compressors that start under load. This
equipment can be safely tested. If an overload is detected, the inverter will simply shut down until the overload
situation is corrected. Use the front panel Reset Pushbutton to reset the inverter.
CAUTIONS
• Exceeding recommended voltage limits will void manufacturer's warranty.
• NEVER try to use your inverter with any 12 volt DC power source that uses a positive ground. (Most vehicles and
boats use negative ground systems.)
• The Power Inverter must be connected only to batteries with a nominal output voltage of 12 volts. The unit will not
operate from a 6 volt battery and will sustain permanent damage if connected to a 24 volt battery.
• Reverse polarity connection will result in a blown fuse and may cause permanent damage to the inverter.

Note:
For heavy-duty use, manufacturer recommends an ANL fuse be added as close as possible to the power source (battery)
positive terminal. The fuse amperage must be appropriate to allow simultaneous operation of all the AC appliances to be
powered, with delay characteristics that allow for the momentary high start-up current requirements of inductive loads. Use
the recommended fuse block (fuse holder) and fuse, or an electrical equivalent. See the "Specifications" section of this
Instruction Manual to determine the proper fuse for your inverter. For full rated and motor start-up surge output, ensure
that the installation is configured to handle the full load.

Determining Battery Size

To determine the minimum battery size you will need to operate appliances from your inverter, follow these steps:
1. Determine the wattage of each appliance and/or tool you will need to simultaneously operate from the inverter.
To do this, read the labels on the equipment to be operated.
2. Estimate the number of hours the equipment will be in use between battery recharges.
3. Determine the total watt-hours of energy use, the total running time and the average power consumption.
Keep in mind that some appliances are not drawing the same power continuously. For example, a typical home-
use coffee maker draws 500 watts during brew time (approx. 5 minutes), but maintains the pot temperature at only
about 100 watts. Typical use of a microwave is only for a few minutes, sometimes at low power.

Protective Features

The inverter has electronic circuit protection against overload and short circuit conditions; and monitors for the
following potentially hazardous conditions:
Low Battery Voltage —This condition is not harmful to the inverter, but could damage the power source. An alarm
will sound when input voltage drops below 10.5 volts and the inverter will automatically shut down when input
voltage drops below 10.0 volts. This indicates that the DC (battery) power source needs to be charged or there is
an excessive voltage drop between the battery power source and the inverter. When the condition is corrected, the
inverter will automatically restart.
Over Voltage Protection — The inverter will automatically shutdown when input voltage exceeds 15 volts DC.
Overload Protection — The unit will automatically shut down when the continuous draw exceeds the inverter's
wattage rating. Reduce the load and manually reset using the inverter's Reset Pushbutton.
Over Temperature Protection — If the temperature inside the inverter reaches 150°F, the unit will automatically
shut down. Allow the inverter to cool for at least 15 minutes before restarting after a heat-related shutdown. Unplug
the inverter from the power source and disconnect all appliances or tools from the inverter's outlets while cooling.
If the Fault LED lights when the (battery) power source is fully charged, follow the steps outlined in the
"Troubleshooting" section of this Instruction Manual. The Fault LED will light if there is an excessive voltage drop
between the (battery) power source and the inverter.
Note: Reverse polarity or short circuit condition may cause external or internal fuses to open and may cause irreversible damage
to the Power Inverter. Take extra care to ensure a proper polarity hook-up.
