Inverters FAQ's
Can I use my inverter in parallel with the generator or
shore power?
Definitely not! If you have a generator on board or a shore
connection you must install a Masterswitch. The switch is
available with various applications, but its main function
is to switch automatically and safely between shore, generator
and inverter power.
Can I run a computer on the inverter?
Yes, you can. All Studer sine wave inverters can easily and
safely supply a computer. In fact the output voltage from
an inverter is often better than that from the electricity
grid. A Studer inverter, combined with a battery charger and
a battery set, is often used as a back-up system on shore
in places where the grid connection voltage is contaminated
or unreliable.
Can I run a microwave on an inverter?
Yes. You can connect any model of microwave to your inverter,
but keep in mind that a 800 watt microwave consumes 1200 to
1300 watt from the 230V system, so you must make sure you
choose the correct size inverter.
How much battery capacity do I need with
an inverter?
As a rule of thumb you can assume the minimum battery capacity
for a 12V installation is about 20% of the inverter capacity.
For a 24V installation this would be 10%. In other words the
minimum battery capacity for an AJ1000-12 is 160Ah.
Are there any appliances that cannot be run
on an inverter?
In general you can connect almost any appliance to an inverter,
with a few practical exceptions. While the inverter can easily
supply a heavy load like an electric heater, the battery capacity
is often too low to maintain the supply for any great length
of time. The same applies to air conditioning units. As long
as the battery capacity is high enough you can use a large
inverter to run a washing machine, a large single cooking
element or a small two-ring electric cooker.
How much power does an inverter consume?
If you connect a 850W coffee machine to a Studer sine wave
inverter, consumption will be 850W divided by the voltage
of the electrical system (12V) = 70 Amperes. Add another 8%
(100%-92% =8%) to this total for the inverter consumption.
The total power consumption is then 70 Amperes + 6 Amperes
= 76 Amperes. Of course a coffee machine is only in use for
about 10 minutes so the actual Ampere consumption is relatively
low (76 x 10 min = 13Ah).
