I recently bought the Multiplus 2 10kva as part of an upgrade to an all Victron solar setup. Before now and for the past 8 years I have mostly used Chinese based inverters (paired with the Victron MPPT smart solar)
While checking out the MP10, I noticed that the AC terminals but in and out had the L and N terminal very close and exposed without any form of isolation or between L and N. Unlike what I saw from the MP5kva which used a non exposed and isolated terminal block. The 10kva is exposed.
I am concern about the risk of
- Accidental touch of such terminal which I think is why even service panel like residential DB, exposed live connection are covered by some form of plastic insulation. Does such exist on the Victron 10kva Multiplus even as an addon.
- Risk of accidental bridging live and neutral. The way the terminals are close together.. it is so easy to accidentally bridge and short the 2 terminals. All it takes is a a loose lug or screw and beng. This inverter is incredibly expensive and in all my 8 years experience I have never encountered such a close exposed AC terminal not in any of the elcheapo Chinese inverters. Is there something I am missing
- The last concern is the risk of arcing. Having L and N so close doesn't this increase the risk of arcing across the terminal? I noticed that there is a physical non conductive material separating the P and N of the DC connection. Why isn't this done for the AC side too.
The above are my concerns I would appreciate some insight into this concerns it would help to understand the thinking into why Victron made these design decisions and any advise would help.
I went through your manual and it was not detailed on how to wire the AC side of the Multiplus 2 10kva. If there is any training material on this particularly as it relates to the Multiplus 2 10Kva AC wiring or any documentation or video that would be helpful. My googlefu has so far not yielded anything
