    Anyone got one and encountering the screaming banshee of an under voltage alarm?

    Mine confronted with a 1350watt kettle (well below continuous rating) immediately goes into under voltage alert and indicates 10.1 to 10.4 volts on the front display. The voltage at the terminals with an independant meter reads 11.9. The kettle continues until boiled but I have to suffer the alarm caused by an incorrect reading.
    Sterling concede the front reading is not accurate but I pointed out that this is not good if this reading is responsible for the noise when it is advertised as relatively silent operation.

    These are not cheap and I thought I'd made a good investment but just now it is sh!te

    Whats the voltage at your inverter DC terminals under load?

    Glad I read this I've been considering buying the same one for ages. Torn between a Sterling or a cheaply off fleabay think I'll eventually go the cheaply route as it'll mostly only run small items and very occasionally wife's hair dryer for 5 minutes max.

    I only stuck with Sterling because I already have the remote switch installed. Now I wish I'd bought a cheapo and wired a remote in parallel with the inbuilt switch :Doh:

    Tech dept want me to repackage it and send it to them for examination. This is hugely inconvenient and I don't have the time nor do I want to be without it. So I'll have to suffer until a more appropriate time :cry: I just wondered if it is just mine.

    I'd worry about small (delicate) item on a whacking big non-sine cheapie inverter. I've just a 300 sine wave. Not afraid to plug in various chargers in that.

    Yep I did mean pure sine but at a fraction of the price and loads of good reviews.
    Pay your money and take the chance I suppose.

    Well, just plug your cheapest small items first.

    Plan B. Good quality 300 and cheap brute force one for hair dryer.

    Get rid of the kettle and the wife.

    Inverter surplus to requirements.

    Sell at Haggers' Bring And Buy.

    Spend cash on beer and pies.

    Sorted.


    JJ :Cool:

    We've just changed the 300w mod sine wave inverter for a 1500w one, (courtesy of Suggy), which runs Rita's 1200w hair drier, and the 900w vacuum cleaner. It comes with a built in 5w USB charging port.
    Apart from testing it out, we've not really had a chance to use it in anger yet.

    Cheers,

    Jock.

    Been using an 1800watt modified sine from sterling for about 8 years now, never found anything it wouldn't run, phone chargers, hairdryers, telly's, computors ect.

    Hi Andy

    Seems a bit basic to me, if you measure the voltage to set off an alarm at least calibrate the bloody voltmeter properly, not fit for purpose.

    Ours is a Merlin but more than twice the price.

    I have just in the past ten minutes photographed the battery voltage at the inverter terminals as 13.42 so float charge from Solars .
    I then turned it on and got the wife to switch on the 1350 watt kettle and the voltage gradually came down and settled at 11.91
    The voltage on the inverter display was showing 10.1 at this time and immediately sounds the under voltage alarm. This is a 1.8volt difference which is at least 10% in error
    Will at sterling admitted the meter is not accurate but it's not good enough if it causes all this noise because it is so far out .
    I'll add pictures when I have better connection

    I have a cheapy 1500w one and have wired a remote (which was not an option on it) just as you propose, works fine.
