    Which bracket?

    Surprised no one has an answer to this one. I guess nobody has ever fixed pv to concrete tiles?

    Which bracket?

    Hi, can anyone suggest a bracket which will suit this roof better? This universal bracket sits 20mm above the tile below, which means slotting and somehow weatherproofing every tile. I guess I need 5mm clearance, but the gap here with this bracket is 20mm. This bracket sits 45mm high, so...

    Sunny boy inverter for wind?

    I have an old sunnyboy 1700 and I'm trying to connect it to a 1kw wind turbine. I've been told that if I can get into the inverter software to change parameters (mppt) then it may well work. Has anyone any experience of this, or does anyone know where I can obtain a usb cable/interface for the job?

    Solar Panels Advice on off grid inverter wanted

    Thanks James. So, if that's the case then it's pretty useless for domestic use? So all the pv generated power, and what power is in the charged batteries will not be supplying the house, and can only be used by any circuits connected directly to the output. Is that right?

    Solar Panels Advice on off grid inverter wanted

    So if the power fails, it can only supply loads connected to its output terminals. But when power is on, will it be supplying the house with power from the pv and that which is stored in the batteries rather than drawing from the grid?

    Sorry, no, it's described as an off-grid inverter but in this instance it will be connected to the AC supply.

    Solar Panels Advice on off grid inverter wanted

    I've been asked to fit a Growatt spf 5000 es inverter which will have batteries (not sure what yet) and tied to the 230v domestic mains supply. Although I'm qualified to fit pv systems, I've never actually fitted any battery systems so not sure how they work in relation to connecting to the...

    Which rail is this?

    Hi all, I need to refit/extend an older installation and I'm not sure what brand of mounting rail this is so I can obtain some compatible fixings. Does anyone recognise this? Thanks :)

    30mm channeling chisel?

    I have those, but they don't include a 30mm channeling chisel, just a gouge tool which is pretty useless when you're cutting out for 30mm conduit...

    30mm channeling chisel?

    Yes SJD, please update us on the quality of the new one. If it lasts over 30 minutes then that's better than the Armeg!
