Assessing The Capacity Of Your Power Inverter To Power A Specific Device - Solar PI5000X Guide D'utilisation

SOLAR Power Inverter USER'S MANUAL
To display the input voltage from your power source batteries, set the display switch to VOLTS. The display will
show the DC voltage at the input terminals of the power inverter. This value can, and most often will, be different
from the DC voltage at the battery, due to the voltage drop over the length of the DC input cables. The input voltage
information provided in this display mode is very useful in determining the charge status of your power source
battery(ies) and the amount of time remaining to power connected equipment prior to reaching a low voltage shut
down condition.
To display the output wattage demand from all equipment connected to the power inverter, set the display switch to
WATTS. The output wattage draw information provided in this display mode is very useful in determining if an
additional piece of equipment can be powered by the inverter without exceeding the rated output of the inverter.

Assessing the Capacity of Your Power Inverter to Power a Specific Device

When you first switch on a powered tool or appliance that utilizes a motor, that device requires an initial surge of
power. This initial surge of power required to start the device is referred to as the "peak power". After initial start-up,
the device then requires less power to operate, which is referred to as its "continuous power".
It is important that you determine both the "peak power" and "continuous power" demands of any device you plan
to operate using your power inverter. The power demands of any particular device are usually stamped or printed
on the device and are usually expressed in either Wattage (Watts) or Amperes (Amps). If this information is not
indicated or the device, reference that device's owner's manual or contact the manufacturer to ensure that it is
compatible with a modified sine wave power source.
To determine the power needs of a particular device, use the following formulas:
Amps Indicated x 110 (AC Voltage) = Watts
(This Wattage amount is roughly equivalent to the "continuous power" demand
Watts x 2 = "Peak Power"
(This is roughly equivalent to the initial "peak power" demand of the device at start-up)
In most cases, the "peak power" demand of the device is the determining factor in whether your power inverter has
the capacity to power that device. To determine whether your inverter has the capacity to power a specific device,
test that device using your power inverter. Your SOLAR power inverter is designed to automatically shut down in
the event of a power overload. This feature protects the inverter in the event that you attempt to power a device
with a power demand exceeding the inverter's capacity.
In the event the automatic shut down protection occurs or the inverter sounds a continuous audible alarm, turn off
the power inverter immediately. Do not restart the power inverter until the source of the problem has been identified
and corrected.
Powering High Surge Loads
Some types of equipment that utilize an induction motor require extremely high peak power to meet the initial surge
demand of that motor. In some cases, this equipment cannot be powered by the inverter even though the power
requirement of that equipment falls within the operating range of the power inverter.
If a specific piece of equipment that utilizes an induction motor is unable to be started when connected to the
power inverter, set the power display to Voltage Mode and observe the input voltage to the power inverter while
trying to start the equipment. If the voltage indicator nears or goes below 10.5 Volts, this explains why the
equipment is failing to start. Check the state of charge of your power source battery(ies) and all connections to
ensure power is being properly delivered to the inverter. If such a check does not reveal any problems, you may
need to upgrade to a larger battery or group of batteries.
