    20 panel commercial use payback

    What portion of the system will be on the flat roof and what do you call a 'slight shade'? In my opinion a flat roof is not worth bothering with unless it is perfect due to the additional price for the mounting gear to get the panels at a working angle. To get the best out of a system where...

    What does 9-30V DC supply mean?

    The +ve (usually red) goes to '+9 - 30V' The -ve (usually black) goes to the 'GND' next to +ve Higher voltage travels further if there is any real distance between power supply and sensor. plus the sensor is likely fixed power so higher voltage means less amps drawn for same power. If the...

    Ecs cards

    Depends who you are shadowing and where they are working. If on a site that reqiures CSCS / ECS then you will need one oof those. As for card grade; with ECS, proof of you currently studying an electrial qualification may get you a trainee card. Otherwise, it will be an Ancillary Operative. To...

    Strange Insulation Resistance results

    EICR - I wasn't alone before anyone states incompetance. The other guy couldn't explain it either. I didn't have one with me at the time, but I will certainly test the meter on one at various ranges. hmmmm, not sure. With the tester I was using it is a press and let go, then it does it's...

    Strange Insulation Resistance results

    I checked everywhere, there was nothing to be found. Even if we say there was something connected somewhere I cannot think of anything that would give results like this. Interesting one isn't it... Wish I had videod it now as people probably think i'm talking a load of rollox, lol

    Can a 250 V IR test still damage equipment

    No, this is isn't related to my last post. Well I guess it is related in the fact both are regarding IR tests, but I haven't blown anything up doing IR tests, lol. If doing an IR test and are unsure if anything it left connected. Is doing a 250 V (L-N) to CPC test safe, even for 'sensitive'...

    Strange Insulation Resistance results

    Here is what I currently see as a strange situation. Though I am hoping that with the responses of a few brain boxes, it will be cleared up. Was doing some testing today and went to IR test a circuit (Upstairs Sockets). I had disconnected everything and even checked that there wasn't a booster...

    Solar PV beginner looking for help

    I agree with binky. I've used the GSE kit and it seems very good. Generally goes in easy too. Especially new build as you fit it before tiling. Again agree with binky on panels / inverters, I would add solar edge to the list too though. But quite costly. Depending on install scenario, fits could...

    To bond or not to bond, that is the question

    That was another point raised in same place. Socket outlets 'could' be used for outdoor equipment (so could any other, in any building, if you tried hard enough). Should have been a C2 and so again an unsatisfactory report. Tested continuity from above mentioned roller shutter guide to MET on...
