Connection and Operation
Check for matching voltage specifications on the inverter and the desired load devices.
Always unwind the DC cable completely before operating the device. Check for adequate air clearances at the ventilation slots to
ascertain sufficient cooling. Never cover the ventilation slots and never operate the device near combustible materials.
Connect the inverter with the DC power supply and switch it on. If everything is connected properly and operated within specified
parameters, the green LED will light up.
General notes on operating AC loads with inverters
In general, all AC loads may be operated with inverters. To estimate the power requirements and necessary reserves, one needs to
know some characteristics of typical AC loads. Most AC loads have been designed for mains operation. One important item to note
however is the required inrush current which does not play a big role when operated on mains voltage since the mains grid is capable
of delivering very large currents. Manufacturers therefore do not focus on inrush current. The inrush current however may exceed the
nominal rated value by a multiple.
•
Incandescent lamps up to 8x higher inrush current within 1 sec
•
Refrigerators up to 10x higher inrush current within 3 sec
•
Television sets up to 10x higher inrush current within 1 sec
Therefore it is important to choose the inverter for sufficient power reserves. For example an inverter supposed to supply a small
refrigerator of 50W nominal power has to deliver a peak power of 500W.
Reverse Polarity Protection
In case the DC input is accidentally connected with reversed polarity the current is flowing across a diode and triggers the fuse. In this
case the proper polarity must be established and the fuse replaced.
Replacing the Fuse
The underside of the device holds a fuse. In case the fuse is blown the inverter has to be disconnected and the fuse replaced with a
new one of the same current rating. Subsequently check the device without any load connected. In case the fuse blows again the
device is defective and has to be repaired by an authorized technician.
