I'm at the very end of my first solar/battery upgrade project, on my travel trailer. Big picture details - 2x200w Solar, Victron 100/50 MPPT controller, Victron Lynx Distributor, Victron Multiplus 3000VA (120v US model). 2x200Ah LifePO4 batteries (Chins) 12v. Victron BMV 712 w/Smart Shunt going into DC bus on Lynx distributor. 30Amp shore power plug. Factory distribution panel with both AC and DC is still in place, with AC-DC converter disconnected.
I've got everything connected, double-checked all the terminations, and am about ready to hook up my batteries to the whole setup. I do have a battery disconnect switch also. Battery + goes to fuse block, then to battery cutoff then to Lynx distributor/busbar +
My last cable run and termination is the AC out from the Multiplus to the AC side of the distribution panel. Per recommendations, I am using marine grade 6/3 stranded copper wire. The 6/3 stuff is super thick and not very flexible and proved very difficult to get wired in to the Multiplus terminals. So much so that I had to keep trying to get them inserted properly and secured, and could have maybe compromised/lost a bit of a couple of strands from either/both wires. I don't think that in and of itself is a huge deal given the number of strands involved, but I wanted to mention is. Also, the terminals for these cables are super close. Out of an abundance of caution, I wanted to check that there was no continuity between the line and neutral wires specifically, like if I have a loose strand that might be making contact with the other wire, even though I don't visibly see that happening, they're so small and the terminals are so close I could possibly miss it. I was not expecting there to be any continuity, but when I hooked up my multimeter, I indeed did get a tone. I took that as an indication that the wires were indeed touching and I needed to re-terminate, so I did. Still getting tone. I checked at the distribution panel as well and also got a tone, and those terminals are nowhere near each other, so now I'm a little unsure of myself. I'm more familiar with DC, so I at this point I am kind of wondering if this is expected.
In doing a little research, I understand that if you have a device turned on in anywhere in the circuit, you should get a tone for continuity. I don't have anything turned on, and there is no shore power connected (I didn't check for voltage, and this may not be relevant, just though I'd mention) I'm pretty sure I even turned off all the breakers and still got tone. I'm not at the trailer now, but I will confirm that again later.
My questions is, am I supposed to get continuity at these points and I should I not be worried about it? I don't want to test anything similar here at the house, obviously with live power coming in that seems a little dangerous potentially.
