🔋 Victron Quattro + EG4 & AO Lithium Battery Bank Upgrade | Split Phase Off-Grid Power System

so let's go ahead and try to configure these inverters to be in Split phase and I'm going to go ahead and put a disclaimer this is the first time I have ever tried this before so we're either going to suffer through it together or we're going to figure it out together all right so uh both of the inverters are on right as you can see and both of them are flashing and from what I could tell from the instructions that's good mainly because both of them are connected via ve bus together right and then we have this blue ethernet cable coming down and connecting to this uh interface MK3 USB we went ahead here and opened up the victron Connect app and now we have uh the victron connect has discovered the multiplus 2 devices so let's go ahead and connect that and it sees that there is a new V Bus system more than one inverter has been detected that's good cuz we have two of them I don't know what the password is from all the Googling that I've done or even just uh thing posts and things we found on Reddit it's either zzzz hold on that's four Z's three Z's one two three and that works so if you ever run into this issue and it's asking for a password just put zzz because that's what appeared to work for me let's go ahead and say connect all units and daisy chain using RJ45 switch on all units which is on so let's go ahead and hit next it's going to do searching let's go ahead and see how well the searching works all right conf it's found two uh and we can either configure them in parallel we can't do uh three phase because obviously we only have two inverters we can do split phase 120 and split phase 180 and 240 um I think most people here will probably if if they make an error will probably choose split phase one 20 but what you actually need is to get split phase 180 if you want to get 240t split phase in the US system uh mainly because split phase being out of phase 180 degrees right uh is actually how you get the uh sinos soal waves to be in exact opposite uh positions as you can see right here top bottom and that phas difference right there imagine there's imaginary line going down the middle so 120 from the middle to here and 120 to the uh bottom down there is 240 right so uh make sure you choose if 180° split phase if you're trying to get 240 split phase in the US so let's go ahead and click next uh there is an option to update to the latest firmware I'm going ahead and say update Manu because I do not want to have to go through this plug it all in and do all of this stuff to go ahead and update the firware later I'd rather just get it all done right now one of the things that you will notice is that on the screen here it says or it's blinking um flashing between bar one and bar two if you only go by reading it you know it says you know uh look at the one that's blinking pretty much right blink as led shown above so if you only read that you you may not get it you have to look at this picture the one that's going one and alternating right because if you look at it here right this one is not doing that but this one is doing that so we're going to go ahead and say this one here is going to be uh conf start configuration and the one that is blinking um this one right here left and right we're going to go ahead and say uh this one is L1 what what I will go ahead and say is that um in a system like this where you only have two inverters running split phase it's really not important which one is L1 and L2 mainly because you only have two units right so it's not really all that critical if you're doing three phase yeah that's probably going to be pretty critical H uh mainly because uh you're going to have three units and if you have an issue with one you're going to go ahead and try to figure out which one that is but it still wouldn't also be as critical in case you uh but it may be in case you're wiring you know something up to three phase but if you have let's say four units and you have them all running in like two in Split phase here and another two in Split phase there then it would be really important but in a unit system like this where you only have two and you know one's phase one one's phase two it's really not super important to do that okay so because we made this one L1 and we selected L1 it automatically went and said this one is going to be L2 I went ahead and just you know labeled L2 up there and L1 up here for this and it will go ahead here and say the bus configuration is complete select finish so once we do finish we can go in here and look at what's going on up in here and we'll go ahead and switch to the uh the screen here so you don't have to look at the screen on the screen so as you can see on the screen right here it's uh inverting and you say AC line output one or input one and two is disconnected obviously you saw already I don't have that connected but line one output is uh not putting out anything and you know that's pretty standard because I have nothing connected to it right uh but you sorry that's input but if you go to Output you know we're outputting 120 here and 120 here you know there probably some idle uh consumption here but let's go ahead and check what the uh the load Center says so this is the load Center that we have connected we'll go ahead and check this tester right here we're on uh ac200 so let's go ahead and wire uh check the voltage here and here and as you can see there or if I stop blocking the view you can see right there we are going pretty much 244 45 43 42 uh 240 right that's how you get 240 but if I take a single hot to neutral right it should be about 120 you can see right there we're getting 121 and if I check the other leg all right right here we are getting 117 121 so each leg is putting out about 120 volts but leg to leg split phase as I was talking to you about earlier across the phases you get 240 in this case really more closer to like 243 245 but nonetheless 240 oh
