As I understand it if you attach your solar to the critical loads any extra generation is still used to charge the batteries or pushed to the non critical loads ? Thanks for the very informative video !

@Frederik Bové I'm living not far away from you I guess because you speak English with an Antwerp accent 😄 I live in a house with a single phase grid connection with 40A breaker. I have a 3 year old PV system with a Fronius Primo 3.0, and almost 4kWp Panasonic solar power connected (inverter is too small because of the prosumer tax in Belgium that was based on the inverter power, but now regulations are different, so I would have chosen a 3.5kW inverter today, but anyway, the topping of the yield in summer is not much, and I almost never use 4kW power in the house). I just ordered a Victron Multiplus II 5kW GX inverter, with 4 Pylontech LiFePO4 modules, that add to 9,6kWh battery capacity. The inverter can let 50A through, so I will connect my entire electrical system to the output 1, the critical load output. So I will install the inverter in series with the grid and the houshold system. Also the Fronius inverter of 3kW is behind the OUT1, AC-coupled. The idea was that I wanted a battery system for increasing my self consumption and autonomy from the grid. If it was only for this, I would have chosen a 3kW inverter with a smaller battery, But I made a larger effort to have a bigger inverter and battery, so that I also can use it as a UPS backup system. To be able to load the battery when off grid, I chose to connect the inverter to the output side. I'm not going to make a separation between critical loads, and loads on the OUT2, that disconnect in backup mode. I just will not use heavy appliances in backup mode, and when suddenly there's a blackout when I'm consuming more than 4kW power, the inverter will just shut down, and we will know the power went out, and will decrease our consumption. So I don't see why I shouldn't put everything behind out1. I had to choose between changing my inverter with a Fronius GEN24 Plus 3.5 inverter or a Victron system, and I doubted for a while. I chose for the Victron because it has some more possibilities, is more open source, and it's made for offgrid usage, where the gen24 only can be used off grid for 15% of the time, or you lose the warranty.

Hey, thanks I learned a lot from this video. One question I have, is whether I need to splice my home grid input cable so that the whole house is powered from the Multiplus. Is this how it is supposed to work? My concern is that it is rated at 3000VA which is obviously not enough if you have the oven and a few electric hobs all on.. - wouldn't this overburden the unit, or does it somehow manage to bypass some grid power if the 3000Va is exceeded? Hope that makes sense..

I am a bit puzzled as to when a power meter or a current sensor is needed to zero feed-in power to the grid; I am designing a DC-coupled system for a house with no solar, so I will be going the nr.3 route, using a Multiplus II and a SmartSolar. All loads will be connected to the "critical loads" output on the Multiplus II. But I need to also connect the grid to the Multiplus, in case the demand exceeds the inverter's capacity, or when the battery is empty. Do I need to install a current sensor for zero feed-in in this case, and if so, why?

Hello, im kinda lost about all the components i need for my grid tied, parrallel system. I also have a Sunny Boy Inverter and now i want to add a Victron Battery Inverter/Charger to optimize my energy consumtion, just like you explained at the begginning of your video. Could you go into more detail about - what Inverter/Charges will work for this kind of system -what energy meter you got, i see no difference for the ET340 & EM24. Will both of them work ? I hope you make an update on your video, on what components you are going to use, and how you installed / configurated them. I'm really interested !!

Thanks for the video Frederik! I’m planning a system with the multiplus 2 as well, and was wondering if/how I can ‘instruct’ to start/stop delivering power back to the grid on a moment of my choice. For example, when you have a variable contract with your grid supplier, that charges hourly prices, how can I drain my battery to the grid on moments the power is very expensive? I read that you can control things with modbus and mqtt. So in short, how do I control when I get/put energy from/into the grid? Thanks so much!

Hi Bove, I've the same gear as you, & want to use a chip fat fuelled 3.5kw generator to boost the battery while my tenant is hitting them too hard, 4 hrs before cheap night charge comes in. If because I'm grid connected I might not be able to use this option, could I then feed genny s 48vpower through a charge controller. ( A proper pain in the arse but doable) Your thoughts please

Very useful video - thanks. I have a few questions, would be grateful for some answers. I'm contemplating a new grid tie install, with Multiplus II, PV and pylontech batteries. My peak load is well beyond the output that the invertor can supply; like 50A. I will naturally put this on AC out 2. What happens when this load is turned on - does the Multiplus II partially supply it? Or does it disconnect and let the grid supply all of it? If it partially supplies it, can you specify the maximum "partial" output?

Thanks for the video. Will victron work without the minimum battery requirement (for each 1.5kw pv 4.8kwh battery)? For example if i have victron's multiplus and ac coupled pv 15kwp using fronius, (without sending energy back to grid) during the day most of the pv power will be used by the loads (AC, servers etc.), will 15kwh 300ah batteries (150a bms) be enough?

Hi, Thanks for the video, it helps a lot. But have one question ... In case on existing SMA PV installation (SMA Tripower 6.0 and SMA Power Mater) do I need to install one more energy meter e.g. ET340 & EM24 or Victron is able, somehow, to read data from SMA Power Meter?

Nice Video, I understand that in case of a power cut the battery ONLY supplies the critical loads because you don't want to feed power into the grid if its out to not endanger anyone repairing the line right? Is there a possible setup to keep the whole system running on battery during a power cut?
@frederikbove
2 жыл бұрын
Yes that’s correct
@barrytresadern9224
2 жыл бұрын
Im no expert, but I believe to keep it all online during a power cut, you would have to connect everything (and have sufficient capacity) to the critical load output only. The link between the inverter and the non critical loads is the same link that connects to the grid and is what isolates the system from the grid when it detects no power (using the power meter near the grid connection presumably).

Thanks for your video explaining the different places that the solar pv can be connected. I have a Sunny Boy too (25kWh) and we have a small amount of power cuts which is making me lean towards the second option so that we still have solar in the event of a power failure. My question is, assuming the grid is up, can loads on the non critical circuit still be supplied by the battery assuming there is enough power available from the inverter? The diagram has a two way arrow so I’m hoping the answer is yes but wanted to check. Also, if the demand on the circuits (critical or not) is higher than the inverter spec, does the inverter provide what it can and the grid provide the extra power as required? Thanks again for your video.

For the first question you need to have a grid meter and then this is possible. For the second question the inverter supplies until the his maximum load and the rest will be handled by the grid.

@@frederikbove thank you, so long as I install one of the Victron 3 phase energy meters as per your drawing then we can also supply the non critical loads from the battery when the grid is on, that’s perfect for me. In the future if my SunnyBoy ever fails I will consider your option 3 and feed the pv to the inverter via MPPT controllers. Thanks again.

I have an existing pv system (with an SMA Sunny Boy) and I'm looking to add a battery to it. I've only just come across the Victron solution so I'm still getting my head around it... My question is this; as well as topping the batteries up from solar is it possible to top the batteries up from the grid? This would be to store cheap rate electricity to use during the day. Many thanks!
