alkafak Posted December 25, 2018 Share Posted December 25, 2018 Hello Everybody please help me how to thread the neutral output inverter, i have test the neutral inverter with test pen and i saw light the pen like phase alkafak Quote Link to comment Share on other sites More sharing options...
Gabriel_2018 Posted December 25, 2018 Share Posted December 25, 2018 Hi alkafak, The difference from neutral and phase id the first is usually grounded. So the current passing trough neutral is the same in phase, so you will see light in pen. Quote Link to comment Share on other sites More sharing options...
alkafak Posted December 25, 2018 Author Share Posted December 25, 2018 Hi Javi, so far i know, the Neutral shoul be 0V or maybe 0.5V, i have measured neutral-ground and draw 120V , this not normal i think alkafak Quote Link to comment Share on other sites More sharing options...
Gnome Posted December 25, 2018 Share Posted December 25, 2018 Really low cost inverters use two live phases 180 degrees out of alignment. Meaning 110v out of phase on both the live and neutral which would give you a phase to phase voltage of 220v If this doesn't make sense to you, don't worry about it, AC power is complicated. The reason they do this is because it is cheaper to make inverters that output this way. The downside is, you can't wire it to a house because your neutral can literally kill someone. So none of the inverters that can be hardwired will be of this type. Quote Link to comment Share on other sites More sharing options...

Are you using IT or TT scheme? Edited December 25, 2018 by Javi Martínez Quote Link to comment Share on other sites More sharing options...
Gabriel_2018 Posted December 25, 2018 Share Posted December 25, 2018 Can you tell us brand/model? Quote Link to comment Share on other sites More sharing options...
alkafak Posted December 25, 2018 Author Share Posted December 25, 2018 Hi Javi, i dont ground the neutral, other then Line and neutral have a ground the inverter is infini 3kw plus Quote Link to comment Share on other sites More sharing options...

You could measure Voltage from neutal to ground and phase to ground in AC IN to confirm it. Quote Link to comment Share on other sites More sharing options...

I have measured grid viltage phase- ground draw 219v and neutral to ground only 1.4v Quote Link to comment Share on other sites More sharing options...
