dual both active grid / off grid solar

Anne Otis

Previously posted " On grid /Off grid Domestic kitchen Choice of grid or solar at point of use 

Thus  kitchen is equipped with both grid and completely independent solar ( inverter ) sockets 

Eg Plug your washing machine to grid or solar  user choice as opportune. Both are live.together 

See attached schematic 

The issue is earthing : Care so that  earth potential to casing of one appliance plugged to grid is not different to another appliance plugged to off grid supply Easily within reach in a domestic kitchen

Previously advised the earth arrangement as in diagram ( earth rod  linked to my incoming grid earth MET ) would suffice Arrangement is similar to UPS systems 

So advised tp contact a locally qualified electrician  with UPS experience to get final approval / sign off 

I cant find one ?? Can anyone put me in touch with such a person locally ?  Or is there a directory ?  I am in south london close to Morden Northern Line tube

    What sort of approval / sign off are you looking for?

    Any electrician can install a couple of bits of green & yellow stripey wire, and an earth rod if you don't already have one.  You could even buy the bits and do it yourself if you know what you're doing.

    Maybe simon , even some suggested that since it is not connected to grid just do it and ignore regs ( like in Devon lol)  

    But no I am not qualified to todays standards

     I seek assurance that what is proposed  is in fact safe If in doubt I wont do it

    The assurance of sign off by registered qualified

    My local guy just "dont know"  None of his colleagues either 

     

    Might add This solution is clear of all the greenwash around.  If its a sunny day put your washing on the line Plug our kettle in.
