I would imagine most people wouldn’t touch the system ever again.

It’s taken some time but I’m starting to get used to the process since I’m using the VRM to download the files instead of wiring up the USB dongle. It looks like most of the functionality has been moved over to the Victron Connect app (except for assistants), but you still have to have a wired connection.

Thanks Bruce! That’s a great idea to leave the charger voltage low to give you a minimum voltage.

Thanks! Yeah, still working on figuring out some of the final wiring.

Thanks! Yeah I've actually seen that in action 1 time because I had some settings programmed incorrectly. The load exceeded the settings and the grid automatically connected to help cover the load. Was awesome to see!

@@AdamDeLay07 that is awesome!

Yeah once I figured out how to do it from the VRM, that’s what I’ve been using the most. Not as easy as it could be but definitely simpler than unplugging the Cerbo each time you wana make a change to the system.

Yeah so the MP turns on the grid relay when the SOC reaches 15%. Once the voltage gets up to 53V (or whatever the value in the vid was) the grid relay will disable and everything will be powered by the battery. Since I disabled the charger in the settings, there will be no grid charging at all. There area actually quite a few different ways to do this from what I've found. Currently I'm testing the Cerbo's generator start/stop function to perform this. It allows me to control the values from the Cerbo instead of having to change through the software. It also allows me to manually switch to the grid if I need to. Right now I'm working on a way to dynamically enable charging. Usually I only ever use it a couple times a year, but only when we have bad storms coming in and there's potential for the grid to go down and my batteries are already low.

Thanks for the tip. Yeah I knew there were a lot more ways than just the simple virtual switch. At the moment I’m testing using the Cerbo generator start/stop to control AC in. Good to know I can do this with ESS as well.

But ESS does not guarantee 0 feed to the grid. At some points, it will feed into the grid. I remember he doesn’t wand to feed into the grid. Just a thought.

That's awesome! Yeah, NodeRed is on my list of things to take a look at. Love the customization options!

I’ve actually started testing using the generator start/stop on the Cerbo to control AC in. It lets me make changes to values from the Cerbo instead of the software. It does seem like they’re trying to move things to VC. It’s a smart move to have a single piece of software.

I had that setup at one point as well, and it worked pretty well, but still used one of the relays on the Cerbo and one AUX input on one of the Multiplus'. The Node-Red route is all software and requires no extra wiring. btw, did you see that there is a new firmware out that prioritizes solar/wind energy? I'm hoping to test it out here this week, hopefully it does what I think it should do and supply power to the inverter if the batteries are fully charged.@@AdamDeLay07

I’m assuming your taking about the assistants?

@@AdamDeLay07 no assistant, same as you set the “ ignore AC “, there is the “flag “ as well, sometimes used to start generator.

​@@aureltanasan1413 Gotcha. Boy it seems like each day I'm learning another new way to ignore the AC In. I think right now I'm up to 5 different ways.

Thanks! I’ve got a long list of videos to make now that the build stuff is done.

@@AdamDeLay07 will be watching!:)

Not sure if I’ll use home assistant or not. I know there’s no integration into Solar Assistant (except for the Smart Shunt), but the VRM is a lot like Solar Assistant.

Do you have some kind of discharge limitation set in the inverter? Do you have it tied to grid or batteries?

Yeah, I haven't updated to the latest firmware version yet to try out the new Solar and Wind priority option. It's on my list of things to do though. I've never looked at AES because my loads never drop super low. There's always something running. What do you have your power threshold set for to trigger and release AES?

Yes you can. The settings actually allow for going up to 64v to handle different chemistries.

It sounds like you need to get in to the VE Config software to be able to change the voltage range. I believe you could also use the Victron Connect app on your phone if you have an Android phone and a Mk3 to USB-C cable.

Yes. Then it switches back once the battery is charged up to 30%.

@@AdamDeLay07 oh ok, so how did you set the value. To 30%

@@carlosreyes6448 Sorry, I've got several videos on the topic and this was one of the first ones I did. So in this video, it will switch over to Grid at 15% SOC and then it switches back to battery once the voltage has gotten to 53V for 5 minutes. I've since changed how I do this and I use the Cerbo to control it all. Much simpler: kzfaq.info/get/bejne/asCjequandSvd5c.html

I really appreciate your help, Adam. This is the same type of setup. That I'm wanting to do. I love victron it's my favorite.

@@carlosreyes6448 glad to be able to help!

I’m not sure these inverters are designed to run without batteries. The UPS feature allows you to run on grid and if the grid goes down, it will switch over to battery power.

@AdamDeLay07 Thanks for the response. When i discount battery power , inverter does not switch to AC input. What should I set to do this. Lifepo4 BMS stop discharging when the temperature is too low (sub zero)

@@goobiie I don’t believe you can change anything on the inverter to make this happen. I would look at creating some kind of an insulated space for the batteries to prevent them from ever getting that cold. Not sure what your scenario is but in the past I used an old chest freezer and a light bulb on a thermostat to keep my batteries warm when they were in my barn. kzfaq.info/get/bejne/msCFiJyD0J2bkp8.html

@AdamDeLay07 This is not going to help. When you insulate the cells, these will get very warm on summer time.

@AdamDeLay07 one more question. Do you have any video to setup multiplus Ii to share power between battery and AC input. For example to run 4kw load take 2.5kw from battery and 1.5kw from grid

Good luck! After the video, I did figure out that you can use the Victron Connect app on a mac to do most of the programming, just not any of the advanced customization (using assistants). You just have to have the Mk3 to USB device. I still have to do an update on that...

Thanks! Assuming you already have your MP connected to your Cerbo and your Cerbo is live on the VRM, you would then go to "Device List" in the VRM and click "Remote VEConfigure". You can then download the configuration file for your MP and make your changes in the VE Config Software. Once your changes are saved (of which they auto-save when you close out of the software), you will upload the config in the same "Remote VEConfigure" area of the VRM. This way, you don't have to have the MK3 to USB cable connected to your MP inverters. You still do have to have a Windows computer with the VE Config Software loaded on it though. Yes, you can connect to the VRM with the base config, I just wouldn't try to turn on any loads or charge your batteries with the MP until you know you have your settings correct.

​@@AdamDeLay07 awesome. yeah, I dont have anything yet. some parts are on its way. some still pending to order. but Im moonlining deep into research and putting all info together. that's why I send a thank you note to your OCD. I'm the same way. so, for what I see there, I do need the MK3 to USB anyway... (was trying to avoid it) my thinking was: what if I connect the Cerbo GX to my network. configure the VRM. connect the GX 50 panel to the cerbo. then physically connect the MP to the cerbo. maybe I can see it listed on VRM, and I can then either configure from there OR download a config file and then load it via victron connect over wifi / cerbo or something. having to buy a $75 MK3 to usb to configure all these seems crazy. wish they could have at least include an ethernet port with DHCP on the MP to connect directly via browser or something. or, being able to configure via cerbo wifi.

@@RaymondCidadMoser I think it's a great idea to do as much research as possible before pulling the trigger. It helps you know what you're getting yourself into. So I haven't had anything I've come across where I HAD to have the Mk3 to usb device. Supposedly there's some limitations of programming through the VRM but I haven't come across anything yet in all my testing. The only thing that comes to mind where you might need it is to initially set up the split phase configuration, but since my hardware all came from Current Connected, they did all that for me. So I guess it kinda depends on where you're getting your hardware from. I did find out later that you can use the Mk3 to USB device to program certain aspects of the system using the VictronConnect app (which can run on both Windows or Mac). I believe that Victron is working on converting everything over to that app, but some of the advanced config isn't available yet (assistants). Yeah, it would be nice for a more up-to-date way to program. Like I said, they're working on getting the VictronConnect app working. I'm guessing for their target market of RV and Marine, most people set things once and never touch them again, so they haven't really focused on the stationary installs. Hope this helps, and good luck on your own install!

Any chance of a video showing how to config MP via VRM without that cable?

​@@mork4911 the thing with with and without the cable is the config options. is the same app (windows or macOS). but when you connect via wifi or bluethooth, the protocol is different. so it loads different info. even the setting page is different. without the cable: is to monitor, turn on/off. change status. stuff like that. you can also control the AC input (for RV if you connect to a residential 120v, you can limit to 15 amp for example) with the cable: is to configure every value on that thing: AC low/high voltage connect/disconnect. DC low disconnect/reconnect. AES mode. power assist and its factor. battery value details. etc. I hope they change this in the feature and allow at least wifi protocol to carry these data. for RV/boat industry, is a pain to have to go all the way down into the unit and connect a cable to change configs.

Thanks! Yeah I did. So there's actually quite a few different ways I've found to do this. The simplest one is using the built-in "virtual switch" in the MultiPlus software (which is what's shown at the end of the video). That works, but it doesn't give me the ability to manually switch to grid mode if necessary. It's on my list to make a video of how I did this, but I ended up using the Relay 1 on the Cerbo and wired that to the Aux Input on the MP. I set up 2 programmable relay assistants based on the General Input flag. One for the "on" state and one for the "off" state. Then on the Cerbo, I set Relay 1 to be Generator Start/Stop and programmed my settings accordingly. It sounds complicated but it really isn't. Using the Generator Start/Stop on the Cerbo, I have the ability to change the SOC levels from the Cerbo instead of having to program with the MP software every time. Plus I can manually switch to grid using the Cerbo. I also ended up using Relay 2 on the Cerbo and Input 2 of the MP to let me control whether or not grid charging is enabled. That way if I know a storm is coming, I can just enable the relay on the cerbo and grid charging will start. Hope that helps.

Great, Looking forward to that video! I just powered my 2 MP-II 5K’s and 200amp Charge controller, 880watts of panels and 30kwatts of battery. Also used Constant Current. @@AdamDeLay07

8800 watts

@@jwl944 I don’t follow

I missed the 0 from earlier post of 880 watts@@AdamDeLay07

You can change a few settings with an android phone. Basically the same settings you can change with the VRM or the Cerbo.

@@AdamDeLay07 not totally formilure with that equipment but looks like it's going to work

Performance wise, OH YEAH! Saving a lot of wasted power with less idle draw, 98% of flickering lights are gone, other things just work. Outside of the one time mentioned in the video, I haven’t once given any thought to what’s running before I turned something else on.

@@AdamDeLay07 sounds like minimal issues and complaints yet

@@royamberg9177 so far, definitely!

It'll be interesting to see if they end up moving everything over to Victron Connect.

Thanks.
