How does a power inverter work?
A power inverter converts DC power into
conventional AC power allowing you to use
your favorite devices when an AC outlet is
not available. Simply connect an inverter to
a battery source, plug your appliance into
the inverter and you're set!
How do I know which inverter to buy?
Different devices require specific wattages
to run correctly and efficiently. Please use
this easy formula to determine the correct
size inverter:
AMPS x Volts = Watts
Example: 15 Amp Cooling Unit X 120V = 1800
Watts
When selecting a power inverter from Boost
Inverters & Controllers, please make sure it
has enough power for your appliance. Just
add together the watts for each item you may
want to run at the same time. Keep in mind
to also add about 15% to the total wattage
to ensure you will have enough power to meet
your needs.
How far can I keep my inverter from my
batteries?
Keep the cables between your inverter and
batteries as short as possible. This will
help your batteries perform their best and
keep the inverter's signal clean. The cables
that come with the inverter are "rated" or
good for up to six ft. If you plan on going
over six ft., drop down to a larger gauge
cable. This is pretty important stuff that
should NOT be overlooked. If the cables
between your battery and inverter get hot
while under heavy load, then you should use
heavier cables.
Can I use an extension cord with my
inverter?
Yes, no problem. If cables need to be run,
it is best to keep inverter as close as
possible to batteries. Use extension cords
on the output side (Vac output) rather than
extending the Vdc cables. Tip: Contractors
often need to mount the inverter in the back
of their trucks. In a case like this it
would be best to mount a secondary battery
near the inverter and wire it to the primary
truck battery. Vac extension cords should
not exceed 200 feet or you will have signal
loss
How long can I expect my devices to run?
The run time depends solely on the amount
and size (capacity) of your batteries.
FORMULA:
·
Total the amps on your batteries and multiply the volts and this will
give you the watt hours.
·
Example, you have a 100 watt light bulb.
Take your 12V 100amp battery; 12V x 100 amps
= 1200 watts divided by 100 watt light bulb,
gives you 12 hours usage.
·
The result will be your runtime in hours. The more batteries you put in
parallel the longer runtime you can expect.
With an inverter installed on a truck,
can the engine be idled to maintain a charge
on the batteries to offset the drain by
heavy power tool use?
Yes, most of our customers will leave their
vehicle running while using their inverter.
We recommend that only 2500 watt inverters
and below be used on your truck or large
vehicle. Advise your vehicle's manufacture
or mechanic to make sure your alternator
will keep up with the amps being used.
What is the Low Voltage Alarm & Shutdown?
The low voltage alarm will sound when the DC
source falls below 10 volts and the
automatic shutdown will power off the
inverter. This is done to save your
battery(ies) so you can restart your
vehicle.
My inverter's fans won't come on
Good! On all our inverters over 1000 watts,
the fans are connected to a thermal switch
which will only allow the fans to come on
when they reach a certain temperature. This
helps keep your batteries holding their
charge longer, and also makes it QUIET!
Is my inverter weatherproof?
No. Treat your inverter like you would your
TV. You wouldn't put your TV outside in the
rain, please don't leave your inverter there
either. Be aware of lighting storms. If
struck, your inverter would go into a
permanent overload state and may even smoke
it. If using in a marine environment, try to
keep it tucked away underneath, in a dryer
area.
What type of batteries do you recommend?
Most of our customers prefer to use deep
cycle marine batteries with their inverters.
A few advantages are:
·
Delivers higher peak amps faster than conventional batteries
·
Provides up to twice the life of conventional batteries
·
More consistent voltage across the discharge curve
·
Superior cold and hot weather performance vs. conventional
batteries
We suggest Lifeline deep cycle batteries,
they work extremely well with power
inverters.
Connecting Batteries Together in Parallel
If your battery application requires more
starting power or reserve capacity you can
install multiple batteries together in
parallel by connecting the like terminals
together (positive to positive / negative to
negative). Each time you add a battery in
parallel you increase the CCA and Reserve
Capacity, the voltage remains at 12 volts.
For example, two 34/78's in parallel
will provide 1600 CCA and 208 minutes
reserve. Three in parallel provides 2400 CCA
and 312 minutes of reserve.
Suggestions for connecting batteries in
parallel
·
Use batteries of identical make, model, and age.
·
Make sure cable gauge is sufficient to handle the higher current flow.
·
Prevent cables from shorting (do not allow them to rub against any
metal objects).
·
Use only high quality connectors, clean all contacts prior to
installation.
·
Periodically check all connections for snugness.
Battery installation tips
·
Ensure that the battery is properly secured
to prevent movement or vibration wear.
·
Do not over tighten the hold down bracket
·
Do NOT use the side terminals.
·
Replace any cables and connectors that have corrosion, rust, or other
damage.
·
Do not install batteries in a non-ventilated or sealed compartment.
·
Do not lift or handle the batteries by the terminals.
·
Do not over tighten terminal bolts
What is the difference between a modified
sine and pure sine wave inverter?
Modified sine wave power inverters are more
portable than pure sine wave power
inverters, lighter, and lower in cost. If
your device will handle voltage
fluctuations, a modified sine wave inverter
should be considered. Most devices that
people typically wish to power will work
fine with a modified sine wave inverter, as
a precaution, please contact the
manufacturer of your device to determine if
it is compatible.
Pure sine wave power inverters motor's run
cooler, last longer and provide very clean
power like you would receive from a power
company. Devices such as laser printers,
digital clocks, and most medical equipment
require a pure sine wave inverter to run
correctly. As noted above, as a precaution,
please contact the manufacturer of your
device to determine if pure sine wave power
is required.
Do I need a transfer switch?
Depending on the Inverter, maybe. Never leave an inverter connected to
a line where other power (shore, household
.etc Vac) may feed into inverter. It doesn’t
matter if inverter is on or off, you will
most likely smoke your inverter.
