Hi,
I am planning to install a hybrid solar/wind power system. When it comes to 230V AC, I'd like to supply power to a home circuit with mainly LED lighting, It will draw probably never more than a few hundred watts. This circuit is connected on the main breaker panel to a 10A breaker,one pole. the neutral is not on the breaker because the grounding system is TN-C (neutral and earth on the same PEN wire), there are however RCDs on the breaker panel (If I understand correctly, it is possible to convert a TN-C system to a TN-CS inside the home by tiyng the grounds together before the RCD while the neutrals are tied to the RCD, but I digress a bit)
I plan to connect the Automatic Transfer Switch standby input between the load circuit and the 10A breaker on the main panel, It is a 2P ATS, so it will switch the phase and the neutral. the primary input would come from the inverter, phase and neutral too after a 2A 1P breaker (I do not trust inverter in-built breakers)
Inverter has ground terminal and inverter ground would be tied to the mains ground at the same level than the ground wire of the standby circuit.
The question are :
Should I tie inverter neutral to the standby input neutral ?
Should i make a bypass connection of the neutral between the ATS input and output, so as to never break the neutral when there is a switch or even if the ATS is in the middle position (no source connected) ?
Advice appreciated !
