    In an earlier thread that I started about floating neutral, we had quite a discussion about, "Back Feeding my Flat", from a DIY, solar set up, I, unfortunately, wouldn't do this because my system doesn't have an earth, several people who replied to my various queries, all said not to feed any...

    Floating Neutral

    I have 6 panels, newfutile, with 6 controllers, 4 heavy-duty batteries, the system will stand an electric Kettle of 2.4Kw, so there is some power available. Mike.

    Floating Neutral

    Tanks again Kim, One of the reasons not to connect to the grid, is the RCBO on the lights, it trips and I assume, it is because there is no earth, strangely the RCD didn't trip. Having spent days and hours of searching for answers, I haven't found any, that explains earthing a floating...

    Floating Neutral

    German energy suppliers are in crisis, all because of solar energy and lack of control, below is a copy and paste, of their version of the problems, plus a short video explaining, "Balcony Solar", which is retailed on the open market and is legal there, it isn't legal here and that is why I am...

    Floating Neutral

    Don't worry mainline, I have no intention of going into the home, grid, electrics, I just wanted to see if it was possible, but with no earth, it is dangerous, this will be a stand alone off grid system, the whole project, was an experiment. I learned some interesting stuff during the process...

    Floating Neutral

    Hi Kim, I back fed the system, via an unused cooker breaker in the kitchen, I have found, but not yet purchased a special change over breaker, where the Grid is on the top at one side, the solar is diagonally across at the bottom and the consumer unit is on one of the other empty places, I don't...

    Floating Neutral

    Thank you, Spanners, for your explanation, first let me clarify, that I have no intention of connecting to the grid, I am well aware of the risks, the few times that I did try, the consumer unit was isolated, twice, once out in a cupboard beside the meter and also the unit itself, this exercise...

    Floating Neutral

    I worked as an electrician all of my working days, but I never came across this issue before, I keep looking for some sense about it and get different ideas from some posts on the net. I know how to supply an earth to any circuit, I have done so many times, by hammering a 3-foot copper plated...

    Floating Neutral

    Another interesting suggestion Tim, if I cannot earth the floating neutral, I am looking at Equalising/levelling transformers, that I believe is one way to get it right, I also believe that transformers, will make paralleling possible. Thank you for your time and reply. Mike.

    Floating Neutral

    I just wrote a long reply, newfutile, but lost it because I was not logged in! The panels that I have are supposed to be 1Kw each at 12 volts, they seem to work fine, the problem that I have, is when I feed the flat, the lights trip, because of the RCBO, in the circuit, I think that it needs a...

    Floating Neutral

    Thank you both for your replies, why the neutral is called floating, I have no idea, both the neutral and the positive go to the output sockets, I believe that I should be able to connect the neutral to the earth without mishap, I only wanted some advice from anybody who knows. I think that the...

    Floating Neutral

    I am a long time retired electrician, I have worked on many different systems, I was High Voltage trained among other things. I understand what floating means, but I don't understand a floating neutral. To amuse myself in my retirement, I decided to build a Solar System, something that I knew...

    Solar Power Expert Needed

    There is no rating label, newfutile, but they work, I will have the system up and running permanently, I hope, in the next few days, I have bought a bigger inverter. Yes, timhoward, this is an off-grid system. Mike.

    Solar Power Expert Needed

    Thank you for the reply Newfutile, here is a picture of the panels, I got them from China, they are quite a recent thing. I have been reading more about paralleling inverters and unless they are built to do so, it is impossible, they must be the same design and manufacture, then on is designated...

    Solar Power Expert Needed

    I am a retired Electrician and started looking at Solar Power, (Black Magic to me), after much reading of "How To", I decided to build myself a system, bat as I don't have a roof, I live in a ground flat, I decided to build a portable unit, I get the sun in the living room in the morning and in...
