Друкувати сторінкуIf the low battery alarm sounds when the battery is fully
charged, follow these steps for correcting the lack of output
power: Reduce the load on the inverter and keep the voltage
above 11.5 volts to maintain regulation. The alarm will sound
when the inverter is overloaded, or if there is an excessive
voltage drop between the battery and the inverter.
NOTE: The alarm may sound momentarily when the unit is
being connected to, or disconnected from, the power source.
This is normal and does not indicate any problem.
INDICATORS AND CONTROLS
PROTECTION FEATURES
Your 8ZED Inverter circuitry constantly monitors the
following hazardous conditions:
A.) Low Battery Voltage – This condition is not harmful to
the inverter, but could damage the power source. An
audible alarm is sounded when input voltage drops to
10.5 volts. When the condition is corrected (i.e.
alternator charges battery) the unit may be restarted.
B.) Short Circuit - Reverse polarity or short circuit
condition of the load will usually result in opening of
the short circuit protection and blowing the three 35
amp fuses.
C.) High Temperature – When the temperature of the
internal heat sinks reaches 66 degrees C (150 degrees
F), the solid state temperature sensor located in the
8ZED Inverter will automatically shut down the unit.
Once it is allowed to cool, it may be restarted.
TROUBLESHOOTING GUIDE / FAQ
Q. The inverter will not run my appliance even though
the listed power is less than the inverter size
A. Electrical appliances can be separated into three loads
by the way they draw energy (current) from their power
supply. These loads are "Resistive", "Inductive" and
"Capacitive" appliances. Some appliances may draw all three
types of power, in which case all should be considered.
•
Resistive Loads such as normal incandescent lights
(wire filament) always draw a constant power (watts)
from the power supply, that is a 100 Watt light will draw
approximately 100 Watts from the power supply at all
times. Resistive loads are the easiest appliances for an
inverter to run.
•
Inductive Loads such as a fridge (electric motor) require
a large rush of power (surge current) to start and then
usually draw a more constant power once running.
Inductive
loads
contain
transformers, ballasts, solenoids). When the power is
first turned on these coils of wire draw a large surge
current which forms the magnetic flux which allows
these appliances to work. The magnetic flux is a kind of
stored energy. Most common inductive appliances are:
fridges, air compressors, transformers, pumps, power
tools & fluorescent lights. These appliances can draw 2-6
times their normal running power to start up. To run a
200 Watt fridge you may need a 600 to 1200 Watt 8ZED
inverter.
•
Capacitive Loads such as TV's may require a large
surge current to start only when they have not been used
for a while. This is often due to large capacitors in the
power supply that must be quickly charged when the
appliance is turned on. If the appliance is not used for a
few days these capacitors slowly go flat. Resetting the
inverter a couple of times may allow these appliances to
work.
•
Some appliances such as large fridges, air conditioners
and other pump driven appliances have extremely high
start up currents, because they have an inductive motor
that must start under load. These appliances are not
recommended for use with an inverter. They should be
powered by an engine driven generator.
Q. Why is it important to make sure that the battery
leads are not connected back to front?
A. The 8ZED inverter uses highly developed electronics to
convert DC battery power to AC mains power. If you
accidentally connect the inverter to the battery incorrectly a
large current will be drawn by the inverter which will blow
the protection fuses, as this occurs some of the high current
could damage the sensitive electronic components. Because
of this risk it is important to always double-check the battery
polarity before making any connections.
Q. Why do some power tools not work properly?
A. Some newer power tools use PWM variable speed
controllers to vary the tool's speed as the trigger is squeezed.
These power tools switch the power on and off very quickly
in a similar way to how the inverter works. Because of this,
some may not function properly with the inverter's modified
sine wave output.
Q. Can I connect lights with dimmers to the inverter?
A. Older light dimmers may function fine but most newer
light dimming circuits are designed for household sine wave
AC power, these may not work properly with modified sine
wave inverters.
