It was good explanation. I did my bypass the same way, except, in my setup MCB on AC-In is breaking the neutral wire too. God knows, why future-me will need to power off the inverter, but I want to isolate it from home circuit.
Thank you. I run a very similar system but I leave the breaker between the mains and the Multiplus in the off position when I have enough power from solar and my 14KW battery bank. If the batteries are running low and there will be no sunshine for a few days I use the changeover switch to run the consumer circuits from the grid and leave the solar system to recharge the batteries. Once chrged from the sun I switch back to running just on solar. I only open the breaker to the Multi if I want to charge the batteries from the grid.
This process is completely unnecessary when you configure the ess assistant. It does exactly this what you do by hand. Also you can set the minimum state of charge of the battery very comfortable in the VRM Portal so that you have enough energy for emergencies. With the Multiplus you have an excellent system but you don't use the good things of it.
@@shadowpv2498 I have not used the ESS assistent yet. I do not want to export energy to the grid, and I also do not want to charge from the grid either. Is it possible with ESS to run through the inverter without charging my batteries when SOC goes down to say 15% and then automatically switch back to battery power when SOC rises to a higher level? My issue is that if I control the system manually I can alread start to use the battery if I know there will be a sunny day tomorrow. If It works automatically it will often be lots of wasted energy as I am not able to use power as quickly as the solar panels will geberate it
ESS tries to level the grid consumption and feed in to zero. So the batteries will be charged when there is excess and discharged when you consume more then the PV is delivering. When it reaches minimum SOC it stops discharging and takes the energy from the grid. If you want to feed into the grid (or not) in case of a full battery can be chosen by setting a switch in the menu. Changing the minimum SOC by PV Forecast of the next day can also be achieved, but this is much more difficult. For this you need some skills in NodeRed and some custom logic. But you can set the minimum SOC very easy by hand in the ess menu if you want to. Also the battery will only be charged from the grid if the soc is very low to prevent damage for the battery
@@shadowpv2498 vielen Dank furs info. Muss ich dann mit ESS rumspielen! I just don't want to upset the system by doing something wrong now I have it working well. NodeRed and custom logic are something I have never heard off so I don't think I will be playing with them any time soon ;-)
@@shadowpv2498 hi Helmut. I wanted to say thank you for your replies. Because of this I was confident enough to install the ESS assistant and am now running the system as you suggest in the video. So far OK, but I may have some questions in future about optimising the set up if you were happy to answer them? Mark
Hello, I need some help of an expert like you with my 3 phase Ess. The problem is that when I switch on the B25 4 pole that is connected to the AC out 1 and the loads of my house than 2 of the 3 multiplus 48/5000 goes in to overload and stops working. Even when te load on my house is only 400 watt. The ac in is connected to the grid. And I have 5 us5000 from pylontech Help is appreciated 😅

Good video, very clear

This was very helpful! Thanks!!
Thank you for the explanation!!!
Why do you need an EM24?
