Hi all . !
I have a 2kw inverter and two 130ah deep cycle batteries for power cuts .
The gas combi boiler would not work in event of an electrical outage either .
So I have a three pin plug connected directly to the combi boiler electrics , so it can be unplugged from the mains circuit and in theory connected to an inverter or my petrol generator .
However having tried both , neither supplies work .
Apparently it is because both the inverter and the generator have floating earths and the circuitry in modern gas combi boilers detect this and refuses to power the ignition .
Can anyone explain to me in terms of an explanation for dummies (me) how to ( by first making sure there is no link to the mains) , that I can physically ground or bond (?) the neutral to earth in a way that does not compromise the mains circuit .
