  • Hi,

    we’ve been busy, so much so that this video is a little different. Will be back to normal next time :P Plenty good stuff to come.

    Thanks for watching! The setup consists of a 255w Hyundai solar panel, Epsolar Tracer 2215BN and a generic 135ah leisure battery.

    This modified sine wave power inverter is rated at 300W continuous with 600W peak power. The nominal output voltage that I measured was 235 to 243 volts depending upon the load attached to the output socket. The frequency remained constant at 50.5 Hz. Power inverters demand high input currents from their power sources and as a rule of thumb to allow for the efficiency loss of the converter you can use the formula of dividing the AC watts by 12 and then multiplying the result by 1.1 to attain the input DC current required. Thus a 100W DC load would require 100 /12 x1.1 which gives a 9.2 amp DC input current.
    Because of this high demand it is better to use the crocodile clips and connect direct to the battery for any load that is greater than 100watts as the internal fusing for the car accessory socket is generally 15 A and its would be unadvisable to run at 10A continuous load on the internal wiring due to heating effects of this high current. The inverter itself does not have a fuse in the cigar lighter plug so this also is another reason to keep the attached load as low as possible for accessory socket powering.
    The unit has a basic modified sinewave output as seen in the video oscilloscope capture and is typical of this type of unit. Because of the high DC component it is generally inadvisable to use this type of inverter with induction motors or transformer based equipment as this dc current would cause heating effects in the unit. The unit has protection for over voltage on the input and will cut out when the battery voltage falls below 10.8v dc to prevent total discharge of the battery. It also will shutdown if the output current is exceeded. The unit has a number of audio/visual prompts as to the error conditions and these are well explained in the user manual. The two 2.1 A USB sockets are powered as long as the unit is being powered from the car battery, the unit does not have to be switched on to enable these to operate. The unit features a soft start circuit whereby the voltage rises quickly to the output level rather than an instantaneous output, this does help reduce start up current surges. The output is fully isolated and as such is safe, no conductor is referenced to a true ground potential so the potential for electric shock is reduced.
    My only concern in carrying out the review and technical testing was the size of the conductors used for both the cigar lighter connector and the crocodile connectors. The cable sizes were not adequately rated if you wanted to run this unit at peak power output. If you really need 300W power it would be more efficient to use say a 600W inverter running at half load rather than this one at full load. Having stated that there is no reason that I can see why this unit cannot reliably supply loads of up to 150 watts using the crocodile clips on the battery or 100W using the accessory output socket in your vehicle. Remember to keep a good space around the unit to allow the inbuilt fan to force cool the unit when the units internal temperature rises.
