A quick set of videos in the Batrium jungle will be posted here as I explore them :)

First 2 below. Adding the RGB led and introduction to adding trip shunt. The trip shunt will have atleast 1-2 more videos.


 
Great work, thats the stuff we need.... more safety.
Btw scared the cr*p out of me whenmy breaker tripped here the first time unexpected..it makes arealy loud "klak" when it go's :p
 
Thanks.

Pretty usefull videos again :)

Do you have a link on where to pruchase the LEDs?
 
Yeah that breaker have scared the heck out of me several times when testing :D Its so f***ng loud :D

All links to the gear can be found in the description on the videos. :)
 
I have a thing to think about... ;)

I have used the "battery ok" signal to activate the shunt trip, this means i had to install a extra relay to "convert" the nc contact of the batrium to a no contact for the shunt... ( on the previus softwareversion there was no pulse or other wayto do this)
So i was gladafter the latest update, to be able to simplefy this to the setupas you demonstrated in the video.

Now i have some doubt....

There is one benefit with my old setup, the extra relay is always activated, i do not like this, but itmeans when there is a problem with the power supply of the batrium system,theshunt trip trips and disconnect the battery...that is a plus i believe..... if connected direct to the relay, the shunt-trip never gets activated if there is a power failure on the batrium side.

Like to have your opinion on this.
 
You are correct in that sense and I asked for the no contact as well. I want the same. Ie make sure that I cannot enable the breaker unless batrium is running...

You want to remove as many issues as possible like if possible remove the relay and use mosfet instead. Relay are often more likely to fail than a mosfet as I understand it. Not sure if its 100% true. But if so there is some mosfet outputs on the Batrium.

I will be driving the ABB breaker by 48v directly btw. Most likely with a power resistor in series to limit the voltage a bit (.....) It should work and its just a pulse so.

I also have the job of getting 1 breaker to be controller by 2 different Batrium systems :) Luckily the first batrium can take input signals and base the switch on that. (I hope atleast.....)
 
Daromer,

I have some noobquestions about the shunt trips.

Is the one that come from Batrium also disconnect the power? If it does, why not use that one?

The next question, it looks like each of the legs are independent, so if you have the 100A model, you could come into do a set up like this and control 300A correct?

Code:
[Inverter] [Charge Controller]
   |     |
[   BUS 1   ]
 L1|  L2| L3|   <- 3 pole shunt trip @ 100A = 300A Total
[   BUS 2   ]
  |    |
[Batt 1] [Batt 2]

If the Batrium Shunt is only a monitor, where would you put it? Between BUS 2 and Each Battery? If thats the case wouldyou would need 2 one for each battery?
 
Shunt trip is a sensor that wil trip based on shunt current in general. A shunt is only a device that meassures current. (I hope i got the terminology right)

The shunt should be close to the battery on the negative side. Before you power the watchmon. The big-ass breaker should be after and to be there to be able to disconnect the inverters and chargers.

If a 100A breaker would be able to work as 300 by paralelelling the 3 im not sure. You can though use it for several banks yes. Best practice in that scenario that i leave to the manufacturer to answer but in theory you could use the breaker on 100A to break 100A per phase = 300A total.
 
Another one in this serie. Lets take a look at how you set up Auto level aka balancing.

 
Have you done any videos on how to hook up fans to the batrium? I want to be able to have the fans kick on when the longmons are in bypass or if the battery case hits a certain set point.
 
I have not. "Yet".. :) Its a good topic and i might do one between Christmas and new years ever. Thanks for the Idea!

Pete@HBPowerwall did this. Check out his channel.
 
He used a loop hole in the setup to trigger the events. The new release of the firmware has it programmed for that function. So one could copy what Pete did, but it would be out of context with the new software update
 
In this video i did a quick rundown of the BMS part and then I end the video showing on how you can find the self discharging packs and packs with uneven capacity with help of the Batrium BMS system. There is one more way to get the data but thats for next video :)
