Dual shunt on Batrium
#1
Hello Everyone 
Is there a way to connect another shunt to the batrium system ? The idea is to have one capture the current/power from the solar panels and the other to capture the load on the batteries.

Certainly - they go in series and operate independently.  I have a Batrium shunt followed by a Midnite Solar Wizbg Jr shunt (for Midnite Classic Charge Controller)

Batrium only uses one shunt. And Batrium is for monitoring battery in/out only so you dont need any more shunt in terms of that.

You can though have as many shunts as you want as said and most common is that the charge controller have its own monitoring in terms of what it produces into the system.

For instance here i have multiple "shunts"

battery have its own and solar have its own including the grid/loads have its own.

Yep, as has been said - the shunts go in series. I have an Outback FlexNet that monitors 1 shunt (it can monitor up to three) and right at the batteries I have the batrium shunt.

Keeping the two in sync is a bit of a pain, they tend to drift a little over time and the genset %SOC start/stop is driven from the value that the Outback FlexNet reports. There is no way to calibrate or reset the Outback shunt value - it assumes 100% when the FlexNet is powered up.

I was thinking of a centralized setup so that I can see what's happening remotely. I have an FM80 outback charge controller but I have no idea how to access its information remotely.

You need an outback Hub, and either an Outback axs port adapter or an Outback Mate3.

You can then connect the outback mate or axs port via wired ethernet to your Internet router and have full monitoring and control from their opticsRe platform.

It works very very well. I've just upgraded a 15yr old system to optics using a mate 3, I don't know why I didn't do it sooner.
