    We have an electric windscreen blind (not sure if it was original or retrofitted) which is powered off the inverter. The last few days it hasn't worked properly, ie it won't roll up or down on one press of the button, and the inverter makes a bleeping noise. We can eventually raise/lower it in stages with pauses in between each button press- it is at this stage that the inverter bleeps.
    Our solar panel is working fine, our batteries are fully charged, we are on EHU. Can anyone suggest where we should start looking?
    I don't really know much about inverters, only that they convert 12v to 230v so please be gentle with your suggestions. Many thanks.

    Hi there, I don't know what size inverter you have but if the blinds have gotten a little stiff, it could be that the inverter is being overloaded, hence the beeping, warning.
    I know inverters give this audible alarm and cut off if battery power is too low but you say they are fully charged and you're on EHU, so I would presume the fault lays with the current draw taking the inverter to its limit and hence the alarm and cut off. You could try cleaning the blind tracks and lubricating with a bit of graphite or silicon spray to free them up. This will in turn reduce the current draw on the inverter. I am not saying this is the cause but it's where I would start. It may well solve the problem. Good luck, Lance.

    I would tend to think that something is binding to put extra load on the motor?

    Thanks @Techno, @Wickolad for quick reply - we have some silicon spray so will try this.

    Presumably the inverter works fine for anything else? if so that would confirm it is a load issue with the blind

    Does it have a manual wind mechanism in the event of electrical failure in the deployed position?

    What state is your battery?

    My 4.5 meter awning only needs a 300 watt inverter so your blind I imagine is a considerably smaller draw but I know if my awning is stuck out that I can wind it in with an allen key even if a tedious task. There must be an emergency procedure for yours? otherwise you'd be rendered immobile

    Haven't checked anything else yet. As we are almost always on EHU we have not really needed to use the inverter for anything other than the blind. Moving site tomorrow so will check once we are settled on new site. Thanks.

    Can't see anything - will try to find the manual and see what it says. Bit scared of trying the blind again just in case it gets stuck down. Thanks.
