    Hi, I'm looking to expand our current grid-tied solar from 2kw to 4kw, add some battery storage and do zero export. Has anyone done this? Did SSE accept it? Any advice on equipment? Thanks all

    Hi All, I've been curious for a while as to how my Solar PV is doing compared to a 'typical' install.

    G59 Solar PV Export Restriction Device?

    Hi all, Bit of a silly question but one I've never really encountered before. A customer of ours want an 8kWp PV system, I sent the application off to the DNO but they have come back saying we can only install 4kWp. I believe I read somewhere before that a device can be installed that limits...
