I just finished building my 48 volt battery bank (EVE LF280K cells) and was going to hook up the inverter. However, the manual shows the AC Out only has Live and Neutral terminals and same with the print on the outer case where the grommet is at. However, inside where the terminals are at there is a ground terminal next to the AC Out Neutral. There is also a ground on out outer case which is what the manual says to use. My question is which ground do I use for a recepticle and can the inverter be used as a portable generator in a wood box where there is no ground pole or an RV frame? I read on some Amazon Q&A for this inverter that people are saying there is power on the live and neutral terminals and there is a grounding issue and others that say it is normal so I am not sure what is right here. Any help would be appreciated, it is the 5000 watt 120V version (model: POW-LVM5K-48V-H).
