Pre-charging the batteries is only required if you are putting them in series. If you are putting them in series you need to charge each one individually and you will need to set up a temporary BMS and charger to achieve this safely.

You have to set this up in programming using the "Assistants"

@ I have ess assistant running is there another one to use with that one?

No the dashboard is only available on a computer.

The Victron BMS range are for Victron batteries only, sorry.

Hello I have another question about the lynx distributor on my solar installation I have 5 strings so 5 mptt smarsolar 150/35 they all have their 40A mega fuse fuse I was wondering if it was possible to connect the 5 smarsolar 150/35 directly to a lynx connector with a 200A fuse? possible? because otherwise I have to buy 2 lynx (expensive) to connect 4 individual smart solar (6MM²) on each lug of the first lynx and 2 others on the second lynx with the multiplus 800VA in all 7 locations on the 2 lynx no risk of gathering all the mptt in 6MM on 1 lug of 50MM²?

@@laurentsosson1739 why do you want multiple charge controllers? Have you considered getting one big one?

HELLO no I don't have the same PV everywhere and not all the same brand on the roof but in different places?

@@laurentsosson1739 I would recommend connecting something to the distributor for instance for each charger to connect that wire to the distributor but putting a midi fuse by it so it fuses down

You won't be able to connect it to the VE Can port. You can connect the MPPT to the Cerbo using the VE Direct to USB interface but you must connect it to one of the USB ports. If you have more USB devices than USB ports you can use a USB hub.

Good suggestion, I will see what I can do.

I'm pretty sure you can not connect NMEA 2000 via USB. You can connect it using the Victron VE Can to NMEA 2000 cable

This is a demo and is not fully functional, It uses the BEP PRO electrical system as an alternative to the Lynx distribution system. You will find both on our website in the COMPONENTS section

Thank you Peter

You seem to have an issue with your controllers that could be resolved with more troubleshooting and without having to resort to Node Red. Unless you are a programmer familiar with the language Node Red is going to be a bit cumbersome for one off uses like this. We envisage it being used in industrial applications where there are multiple iterations of the same installation.

@@pkysinc This is the 3rd year these Victron SmartSolar 100/50 have been in service for my Offgrid solar. One of the six has already developed an issue with its current sensor and got sent back for warranty service. Of the other 5x, they are connected via Bluetooth plus the VE Direct connection. Whether this is running with the Smart BMS 712 or now the Lynx Shunt, the random inactive charging issue still persists. Sometimes it is one, other times two units, but i have not seen three. They don't have CAN bus communication to the Cerbo GX, like my other 150/100 do, that is one main difference. And the 150/100 never developed this issue, despite running on the same network and serving the same period of operation. I am not sure, but i think there may be a QC issue with these 100/50. They are not as robust as the 150/100. Obviously they run different firmware. As a software developer, i have the technical background to develop software solutions to address problems. I don't mind doing so. I tried pinging with others but few run as many controllers concurrently like my system, so they have not encountered this problem yet. I did encountered the random temp compensation issue that Andy ( from Offgrid garage) mentioned which stopped the controller from charging... this happened out of nowhere one morning. But overall, i am familiar with the type of tantrum these 100/50 can throw at me now, so if there is an easy way to develop counter measures against them, it would be the easiest approach i can take to ensure that the system continues to run 24x7 with minimal supervision. Unfortunately i do not have visibility to the firmware code for the 100/50. But it wouldn't be difficult to add a sanity check when the PV voltage is Not zero or a certain threshold, and the controller has NOT been disabled that the controller should NOT be in the OFF charging state. It should be reset to start the Bulk/Absorption charging state. The funny thing is, even if i go through the menu to disable the charger when i see this problem, if i don't wait until the pop up reminder to suggest enabling the changer, before re-enabling the charger again, it won't fix the problem. The re-enabling MUST be done AFTER the pop up reminder appears... so this is one observation i noted. It definitely looks to me like a software /firmware bug. And the problem can occur in any of my 6x 100/50 controllers, it is not localised. Compare this to the 150/100 that runs a different firmware and never experiences this issue, it further reinforces this speculation that it is firmware specific issue.

This is not the correct place to be discussing this

Any ON-OFF float switch would work for that application.

@@pkysinc do you've a sample? Can you suggest me also a temperature sensor?

We made them here in house, im sure there are places you can buy them

You need a VE Direct cable to go between the Cerbo and the BMV

This video describes programming the MultiPlus locally using your laptop and Victron Connect. While it is possible to do this remotely over the VRM it is for advanced users and uses a different program. I wouldn't recommend trying it until you have become thoroughly familiar with doing it locally first. We don't give out the instructions but you will find them in the VRM Portal Documentation

You have to connect it to your computer using the Mk3 USB interface

The plugs should be available through a Victron distributor. I haven't found them commercially available except through Victron. We recommend you plug them all in when the unit is new, even if you are not using them. That way they don't get lost.

Did you order from PKYS Inc

@@pkysinc no. Not from PKYS. I’ll look you guys up. Thanks for the great video.

OK think of us in the future, @@tomaskey6844

Victron just had a 30% price drop on their 330 amp hour battery, and a 10% drop on the rest of the Smart Lithium range, as well as a 40% price drop on solar charge controllers.
