    Landis & Gyr flashing between two meter readings

    Just a quickie, we've installed loads of Landis & Gyr 5235B generation meters but the last one I did alternately displayed an 'r' alongside a 0 kWh reading and then a 't' alongside the PV generated reading. I guess it's a twin-rate display or some such thing; is that to be expected (and ignored)?

    LED Drivers - flashing lights!

    Folks, Fitted a bank of 6 LED lights last week....3 x 4W lamps on 2 x 15W LED drivers. When I powered up they flash on and off. Taking them down to one LED lamp per driver they light normally. I'm guessing that the flashing on/off is an under-power issue? Should a 15W driver be able to...

    I have just achieved mcs accreditation and have been asked to install a system on a slate roof. I am aware that some installers drill the slates and use sealed bolts to fix the mounting rails, I'm not overly keen on drilling someones slate roof and was wondering weather there is an alternative...

    Flashing display on new import meter

    My DNO installed a new meter last April. When I came to read it today the display is flashing between the figures and 'rEd'. Is this a meter fault and should I report it? The meter is a Landis & Gyr Type 5235A.

    Hi all. In my daughters bedroom I noticed that after turning out her light it kept flashing (almost exactly every 4 seconds).
