For the BMS integration in VENUS OS / GX device see this discussion. https://diysolarforum.com/threads/victron-venusos-driver-for-serial-connected-bms-jbd-daly-ant-jkbms-heltec-renogy-tian-ecs.17847/ For the battery protect, I have checked my own Orion 24/12 in my camper. I have the smart...

You can also consider to use a multiplus II GX 48/3000. Then you have the functionality of the Cerbo included in the multiplus. It saves a few cable’s and a device. The BMS can also measure the SOC and other parameters identical to the smartshunt. So why not keep the money in your pocket from...

Hi Live, I had the same setup and concern. Victron clarifies the limitations of this setup in this artilcle. In short the PV power should not be more then the Multiplus power. So if the multiplus is 3000VA (2400w) then your PV should not do more then 3000w...

Take a look on this website in NL, I don’t know if you can switch to English, use Google translate to translate the page. I have ordered here multiple time and they are reliable. https://www.rdae.nl/anl-1-zekeringhouder.html https://www.rdae.nl/sb175-175a-grijs.html

One word of caution. I run a domoticz system 5+ years on a RPI with great success. But I have experienced regular failures of the SD cards used. First I didn’t understand but after some reading on the internet it became clear. SD cards have a limited amount of Read-Writes you can do so they will...

Correct me if I’m wrong but the smart shunt is messing on the DC side in the negative line what goes in and out of the battery. So the eff is the battery efficiency and not of the charger from AC to DC. If you can measure on the AC side of a charger and on the DC how much energy goes in and...

I have purchased 64x LF280K in October, they arrived just before Christmas and currently testing all the cells. So far we have tested 23 cells. Charge to 3.65. Discharge to 2.70 volt With 40a. The best cell is 280ah (1) and the worst cell 250ah, the others are between 260 and 270ah On average...

the multiplus II GX doesn’t need all the cables and has the same functionality as the Cerbo to my understanding. It also runs venus os. more info on the integration of the BMS into the venus os you can find on below 2 links...

Hi, I stopped my search for an DC MCCB and used fuses instead.

I have 4 PD/USB chargers in my mobile home. With a switch connected to 24vdc system. It works good, only disadvantage are all the lights they build in the little chargers. For me it is not needed since I charge the devices when we sleep and then all the lights is to much. I bought these with a...

Well wait until you live in Netherlands, due to the whole Ukraine/russia situation we pay on 1 jan 2023 96 cent/kWh. And feed in rate is 16 cent/kWH. Per 2025 we can not subtract the feed in of power from the consumed power over the year so a battery becomes attractive.

I tested all codes with a QR scanner and all where valid. All cells where build on the same day 3/June/2022 and the serial numbers are all in a range of 200 following numbers. The tester I’m using is the EBC-A40L. Once all cell testing is completed I will post the full results on the forum

In Ireland and Belgium there is no money paid back to the producers of Solar energy. In Ireland everyone that installs solar panels also installs battery’s to store the self produced power instead of sending it to the grid for free and later buying it back. As I understand from my colleagues...

I had to be on the roof of my RV today so made some pictures so you have an idea of what you can do. the panels I used are normal panels which I also have on the roof of my house. No special RV panels or for boats. I have a home build RV with a complete flat roof except some items that are on...

Just want to post that I was able to connect my JK BMS with bluetooth connection to the RPI VenusOS in my camper. It works like a charm and nice to have now everything integrated into venus OS. Thanks for making these efforts and the software available for everyone working on this. I'm using the...

No I don’t have the consumption measured like you have. Only the bar graph for Solar power generated in kWh is displayed.

I have the same BMS B2A8S2oP on 8S 280AH battery in my mobile home. I just assembled everything 2 weeks ago and during the commissioning I tested everythinog to the max. I have a 2000VA inverted and pulled continuously until the battery was depleted 80a. The inverter was connected to massa with...

Hi, I want to purchase a MCCB for my 16s 280ah battery bank to have a protection but also a switch to isolate the battery bank. I live in the netherlands and struggle to find a shop in europe that sells 125A DC breakers for a reasonable price. Since this is a essential piece of safety equipment...

Please also take a look at this document from Victron about the factor 1 rule when connecting a PV installation on the AC-out. https://www.victronenergy.com/live/ac_coupling:start Another consideration is to purchase one Multiplus II GX, you then have the cerbo integrated in the multi and don’t...

You can also connect the main current circuit directly on the battery Bypassing the BMS and then leave the circuit of the key switch/solenoid on the starter motor connected on the BMS. When battery voltage then gets to low the BMS will still protect the battery and switch off the...

For the SD card, there are options to use a so called RAM drive to reduce the r/w to the SD card. Search the web how to do this. I now try with Sandisk Max endurance cards. I have also an VenusOS installed on a RPI in my camper to monitor all victron equipment. I needed 5 USB ports and have 4...

from the screenshot it looks like you can assign a unique address to each BMS. I would give it a try, if it doesn’t work then you can order always a few more RS485-USB interface. One more TIP, when I made my Victron VENUSOS pi I had random issues that the communication between the victron...

The cells where purchased from Docan power and advertised as typical 270-280ah discharge. No grade was mentioned, they came with the single bolt connection. And agree with above statement. I just want to make people aware. I took a gamble with the purchase and somehow expected this. The intend...

Go to the VRM portal and you can try the free Demo and see several installations and look at the data that is available. As far as I can all signal have also a trend, graphs, bar graphs and so on. https://vrm.victronenergy.com/installation-overview

I just commissioned the ESS for my parents and yesterday while it was charging at max capacity we where shocked about fan noise. I searched for other users input and passed by this discussion on the Victron community’s. It is a long and intestines thread. Click here at the end of the tread a...

I had the same issue during my Summer holiday with the camper. Since the battery where never fully charged the SOC started to drift and getting towards 50%. But after a short charge from shore power (which I never use normally) and charging too full voltage the SOC was correct again.

I seen you are using 2x multis, I was also thinking about the situation where one would fail and the other is still functional. Maybe consider some hardware to automatically switch off the Fronius in case of failure of one of the multis. But maybe I’m overthinking this to much. I have Venus OS...

I have bought cable’s and other parts I needed for the ESS here: www.rdae.nl, he ships also international. The cable he supply’s is from the brand Ripca, they have a website but you can’t purchase directly from them. The quality of the cable is good in my opinion, fine stranded cable with a good...

For IOS there is a specific VRM app from Victron. If you install this and make the correct settings on the Cerbo/VenusOS you can duplicate the Cerbo screen (remote Consol) in the VRM app And duplicate the screen this way. It works great, the only disadvantage to work headless on a Cerbo or...

Also consider the company Moxa. They make industrial networking products like routers, switches access points, fiber converters And so on. Good quality reliable products but they come at a price...
