This system is hooked up to a load center and is programmed using the Victron Interface MK3-USB-C (VE.Bus to USB-C) connected to a macbook pro. In the programming options there are options to operate the inverter chargers in parallel, 120 offset, and 180 offset. To get the 240v Split phase for use in the United state, we use the 180 degree offset. The Victron Energy Inverter chargers in this episode are connected to the EG4 Indoor Wall Mount battery.

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