    Morning GCE

    Thank you for the excellent advice, I have stared the neutral and earth on the output and all is as it should be.

    This has been a very interesting installation in the SANS 10142-1 pg 363 (Annexure P3) this is for UPS, The only alternative supply that does not get a star point is the ups setup.Click image for larger version.

    An interesting point to be noted for those who have an auto change over switch connected to a generator...load shedding at 10 pm when nobody is at the office means the generator will be running for the off period for wasting diesel...for some this could get expensive especially if the power is off for longer than 2 hours...money down the drain.

  3. Thanks given for this post:

    Reading through this thread...how things have changed.

    Solar has become more affordable...and you can buy directly from China.

    Inverters can now be grid tied...linked to solar panels etc.

    Batteries are more expensive (a lot more) but with lithium the buzz and people offering 15 plus years life .

    Generators...can be a smooth pure sine wave seeming switch over...with displays offering everything from a pure sine wave to current...power and even harmonics.

    all you need is a second bond R100k plus and you can be enjoying the 2 hours loads shedding with your lights on and internet access...or you could save a R100k plus and enjoy 2 hours of quality time with the family playing board games or interacting with other humans face to face.

    Something to think about before you rush out and take a second bond...all your electronic devices including your router generally have a 2 hour plus backup battery on board...so you can still share you isolated life behind the screen for the 2 hour load shedding period.

    Evening All

    I have been installing a lot of inverters with batteries and my challenge is indication lights for samite DB's, they don't make them. I install a seperate box next to the existing DB not a pretty site.
