  • I power 500w 1200W Surge , pure sign wave Inverter.
    Or is it ipower who cares :o )
    Looking at the video again, i noticed my MISTAKE.
    Amps Drawn was not as i said, it was more like just under 6 Amps.

    This is my latest bit of kit to use with my Solar panels, Its November at the moment.
    Most days its either overcast or raining, either way i will be using the ipower 500 as often as i can.
    At the time of the video, the inverter had never been turned on.
    I Power do make larger inverters, this little 500w one suits both my requirements and my pocket.
