I am also running an AM2 on a Luxpower SNA5000. Apart from the 50AH reported by the inverter, the battery has served me well. I did have a bms issue, but Hubble swapped it out for a new one. I even queried a SOC anomaly last week which they checked via anydesk. I can honestly not fault their service. Just for that reason I want to get another AM2.

How about this, inverter chassis earthed via plug (as if its an appliance), and then bonded earth and neutral to ELR to downstream connections form inverter?

I did these connections. Sadly, there is no way to add it before the ELR, unless I plan on leaving the unit installed in the rent house - and that is not an option. Adding an ELR in after the inverter is no problem though.

Thank you for the welcoming guys! That is indeed correct. How should I go about it then, add a separate earth leakage between the inverter and equipment? And then not connect the earth of the inverter? 1. Checked those many times, up to the point where only the inverter was connected via plug to the mains. 2. Supposed to, but not yet - I just wanted to check if the inverter powered up and charged the batteries.

Hi Guys, I got myself a Proline Energy 3kVA inverter as a backup power source - in case of load shedding or whatever. I used to use a Mecer 1200VA inverter, and it was working well, bar being modified sine. The main use for my setup, is my office, I work from home and cannot afford to sit in the dark. So the idea was simple, replace the Mecer with the Proline, in a temporary install. Reason for this is that we rent our place, and I'm for sure not one to invest in a backup system, just to leave it here when we move. So I build a trolley that hosts both the inverter and has space for 6 batteries. All looked well and I connected the wiring, just to have it trip the earth leakage in my office. My office is actually one of the out buildings, so its fed from the main DB in house, to a smaller DB in the office, with an earth leakage and 2 breakers - each for a plug in the office. One of these plugs feeds the inverter: Here is the problem, if the inverter is plugged in and off, it charges the batteries until full, at which time the fans stop running and all seems to be in standby. As soon as I switch the inverter on, it trips the earth leakage in my office. Note, there is no load (i.e. nothing plugged in). Any ideas why?
