Batrium and Victron? What can it do?
#1
Question 
This thread is heavy Batrium. If there is anothe forum that is more suited for Batrium questions, please let me know.

I'm looking to upgrade my BMS and Batrium was always off my list as you needed to buy the watchmon, plus the expansion board, plus the cells mons for how I'd want to run it. However with the new Watchmon4 with the two FETS, for my application I'd no longer need the expansion board so it's a bit more appealing. I just saw with the latest release that the Batrium can now control the Victron inverter through the color control unit. This is pretty interesting as my current BMS doesn't have anyway to control the inverter/charger. My installation has the following:

Charging sources:

MPPT 30A controller
Alternator through starting battery and battery connector contactor (with manual switch and only used for emergencies)
Shore power through Magnum Inverter/Charger

Loads:

DC Loads through fuse panel
AC Loads though Magnum Inverter Charger

I'm was thinking about upgrading to a Victron Inverter Charger as that has manual relays for controller the charger and inverter functions so I could wire that up to my current BMS (you can see here: https://www.victronenergy.com/upload/doc...ros-EN.pdf) However I saw that you can connect the batrium to Victron's CanBus. I'm not sure if that's going to be available on the WatchMon4 or not, but that's a really nice feature that made me think about what else can the batrium do with the Victron Color Control? Can it disable and enable both the inverter and charger? I was thinking about upgrading my solar controller to a victron, but my current MPPT has a shunt hooked up to the monitor so it's my MPPT remote and battery monitor. So if I upgrade my MPPT, I'll lose my battery monitor. The obvious choice was to go with a victron battery monitor to integrate into the color control. However if the batrium can talk to the CCGX, is it possible to send battery SOC to it as well? Can it do anything with the MPPT data for logging/display? 

I'm not a programmer, but I know that the Victron Venus GX OS is open source. I know the Batrium team is small, but curious if there are any future plans for further development with Victron products?

Here would be my proposed setup for the Batrium (if it would work). Getting the Battery SOC from the Batrium to the CCGX would be fantastic.

The main function for the BMS hooked up to the inverter is that it controlls the charging in 3 steps.

1. Max charge enabled
2. Minor charge enabled to top off the battery bank and let the batrium balance
3. charge disabled

This to make sure the packs arent overcharged and that the Batrium BMS doesnt have to trigger the breaker and disconnect the battery bank.,

Do you happen to know if the inverter can be disabled via canbus in a low voltage condition? There isn't a lot of documentation on the site yet about the victron setup.

I have no insight of Victron inverters nor their protocol. I can only tell what the Batrium does and it only cares for the battery charging part as such.

Your question is complex and not a simple answer... 

From the latest release 1.0.30+ there is a the Victron  CCGX canbus communication profile option.

There are a number of Victron products with different capabilities depending on the various Victron product combinations. We rely on solar professionals to advise a suitable configuration and product selection. We are not Victron experts so cannot advise specifies...

The "Victron MultiPlus Inverter Charge" was used in the project we were involved in testing. This equipment had both charging targets for voltage and current and discharging voltage cutout and current (amps) that could be preset. Charging is something you typically adjust in a ESS application. However discharge is typically limited to on/off unless in a hybrid mode where power can be blended from both the grid supply and battery. In most offgrid modes this is limited to on of off and reverting to a different source (i.e. generator).

The SOC% is sent to the CCGX as part of the protocol.

Once the pilot project has been signoff off we will do a step by step guide but this will be after the release of Watchmon4 supervisor hardware.
you question is complex and not a simple answer... There are a number of Victron products, we are not experts in their range nor have had any training. We rely on Solar professional for that insite. What we can comment on in the integration with the Multi inverter/charger, this is fully configurable both for charging targets of voltage and current and discharging voltage cutout and current (amps). Charge is something you can adjust in most modes so the bms can adjust as required. However discharger is rather different and will depend on the mode. As only in hybrid grid support can you blend power form both the grid and battery hence reduce the discharge current. In off grid mode that does not make sense it is either on of off and reverting to a different source (i.e. generator).

hope that helps answer your question

Jaron, your link won't work cuz it's coming from your mail. You need to save it to your local drive and then upload it to the forum Wink

A write up would be great. Thanks!
