to choose an inverter
choosing an inverter you ill have to decide on the following:
produced by the inverter.
utility power provides/ produces a “Sine Wave” form. It is therefore
important that your inverter also produce
the same waveform. Unless the inverter produces a “PURE SINE WAVE”
it will have long term negative effects on your sensitive appliances.
All our Microtek inverters have a PURE “SINE WAVE” output.
of inverter needed
inverter size (600Va, 800Va, 1400Va, 3KVa, 5.5KVa) will determines
"what appliances / how much" you can power.
choosing the right inverter size, find out how much wattage is required
to run your equipment. Most appliances have their wattage stamped
on a back panel or listed in the owner’s manual. If your appliance
only shows the AMPS, use this simple calculation:
230 volts x Amps = Watts.
check if the inverter’s surge rating meets your requirements i.e.
motor, TV’s and some other appliances often require three to four
times more wattage at start up.
consideration should be given to “what you will be running at
any given time”. Although the inverter can be connected to a
lot of items, you may only be running a few items at a time. (eg.
Inverter connected to computer and TV, but you would only use one
item at any given time.) Thus, your load will be relatively low.
It may not be necessary to have an inverter to “run everything”,
but rather “what you would use at one time”.
inverter with which batteries
battery size (100 Amp/Hr (AH), 105AH, 165AH, 200AH) determines
how long the inverter will run during a power outage.
1 battery system (12V) (100AH
1 battery system (12V) (100AH to 165AH)
2 battery system (24V) (165AH
4 battery system (48V) (165AH
8 battery system (96V) (165AH
should be noted that the backup times will vary according to the
batteries you choose. We do not recommend using bigger batteries
than stated above as the inverter will not be able to fully charge
batteries not within specifications. (e.g. 800Va inverter with 200AH
battery). Using smaller batteries do not affect the inverter performance,
but do affect backup time.
