I would suggest the UL listed version for $40 more, has more space in the wire box as well as a bonus
Victron 48V MultiPlus-II UL1741 3kVA 120V Inverter 35A Charger (UL)

The multiplus II is for 240v I believe. Standard multiplus for 120v. You can download and read their spec sheets at victronenergy.com and I'm sure one of these guys with a multiplus will chime in.
Non US Victron models run as 230/240V, no need to pair two together for split phase 120/240. However to get 120V out of one of them you'd need an autotransformer etc.
Multiplus 2 is a multiplus 1 or multi grid with ability to use CT sensors I believe, can be had in non split phase 230/240V or US 120V.
He's showing the zero load (idle) consumption.
They all have a power draw of their own, quite significant for some. The larger the inverter, the larger the parasitic draw, in general. On some inverters it is 100W or more, and will drain your whole 100Ah 12v battery if left on overnight. This is why all power stations have an on off switch for ac inverter, and you turn it off when not using it. Finding an inverter with enough Watts and surge to start and run your loads, while having the lowest parasitic draw, is pretty much the main design challenge for inverters. This is also a reason why many truck and van setups, folks will also have a small 300W inverter that they use in preference for small AC loads, or as an always on setup for charging tool batteries, etc. Because it is enough for many small jobs, and has like 2 or 3W wasted power only.
Looks like if I wanted to I could tap into that and put another switch anywhere I wanted.
Why would I get the Cerbo GX verses the Cerbo-S GX (Lite)?
I have both the normal and lite model. The normal one has 2 CAN port pairs and the lite has only 1. You need the normal one to connect the batteries BMS to the system. When the batteries are connected then they'll control the entire charging system and give you correct SOC, eliminating the need for a shunt.
I will probably go with the SOK batteries. But it sounds like I could go with the "Lite" version Cerbo-S GX with the SOK's and everything will communicate, right? I only need one CAN port for my wanted setup, right? I sort of doubt that I'd ever go more than 2 batteries. But one for starters.
If you don't plan on having any ve.can items then it looks like you can change the setting for those ports to canbus then it'll work. Not 100% though
If you need battery comms then the Cerbo-S doesn't have the two BMS-Can ports of the full fat GX shown here
Yupp but there's this option to change the vecan middle ports to can-bus. Actually might even be able to use both vecan and canbus
Yes looks like some BMS protocols allow both devices on the one chain, this would generally be if you had some ve.can connected mppts to connect as well. I would treat it as an either/or option to avoid disappointment. If you have ve.can devices to monitor in addition to BMS connectivity then spring for the full fat GX.
Can uses 2 ports to create a loop. So it goes from cerbo to bat1 then each side has a terminator. The batteries connect together using their own ports and have dip switches to set the order.
