Controls and Indicators

Controls and ON/OFF Switch
Indicators Turns the control circuit in the inverter On and Off.
It does not disconnect power from the inverter.
When the switch is in the Off position, the inverter
draws no current from the battery.When it's in the
On position, but no power is being supplied to the
load, the inverter draws less than 500 milliamperes
from the battery. This is low current draw. It would
take more than a week to discharge a 100 ampere-
hour battery at this rate.
Don't worry about excessive drain on the battery if
Operating you leave the inverter switched On for a few days.
However, do switch it off if you are not planning be

recharge the battery within a week or so.
Power Output
The inverter will deliver 2000 watts continuously. It
can deliver 2400 watts for about 30 minutes.The
inverter must cool for 15 minutes before it can
resume operation at 2000 watts. Note:The wattage
rating applies to resistive loads.

The inverter will operate most AC loads within its
power rating. Some induction motors used in freez-
ers, pumps, and other motor-operated equipment
require very high surge currents to start.The invert-
er may not be able to start some of these motors
even though their rated current draw is within the
inverter's limits.The inverter will normally start sin-
gle phase induction motors rated at 1/2 HP or less
Input Voltage
The inverter will operate from input voltage rang-
ing from 10 volts to 15 volts. Optimum perfor-
mance will occur when the voltage is between 12
volts and 14 volts. If the voltage drops below
10.5+/-0.3V volts, an audible low battery warning
will sound. The inverter will shut down if the
input voltage drops below 9.5V+/-0.3V volts. This
protects the battery from being over-discharged.
It will restart when the input voltage exceeds
10.5V+/-0.3V volts.
The inverter will also shut down if the input volt-
age falls to 15.75V +/- 0.75V. This protects the
inverter against excessive input voltage.
Although the inverter has protection against
over-voltage, it may still be damaged if the input
voltage were to exceeds 16 volts.
