Smart Shunt

[TxMN2020]

Do The 2025 OTT’s include a smart shunt with The lithium battery upgrades?

Prior to doing some upgrades on my electrical I had the opportunity to look at a 2025 on dealer lot near us and snapped a few pics. It does have a smart shunt.

Actually I’m pretty sure that is the BMV712 shunt not the smart shunt.

You are correct, still requires the display but does also have Bluetooth feature for the victron app. The smart shunt is Bluetooth only with no display.

I've never seen a setup using two shunts. I wouldn't know how that would even work.

Additional shunts can be installed to monitor subsystems, different battery banks, multiple solar arrays, etc. not much need in an Oliver, but…

Our hull has a shunt wired to the display for the original solar charger. You can only read SOC and amps */- when in our hull looking at the display under the pantry. This would be the same for the BMV712 shunt mentioned above, wherever you mount the display, though this Victron product might have a Bluetooth sender or one can be added.

I left the original shunt as-is and installed this Victron SmartShunt so I could read battery status outside the Oliver, in the TV while driving, even from my living room window at home! I spent $90 to add this and it’s been worth it. Download the app for no additional charge: https://a.co/d/4hKmfCW

For us dummies, can you show a picture of the "shunt wired to the display for the original solar charger"? Where is this shunt located?

The assembly in the right side of the photo sort of looks like a fuse. The main cable looks like it is attached to the upper end of the shunt then from the lower end of the shunt crosses over to the lower end of the fuse/junction block, through the fuse/junction block and out into the world. Maybe?

That’s the negative bus bar

Thank you, our forum friend, no dummies here!
I've respected many of your special posts as well. PM me if you want info specific to your hull.

My first pic is the original Blue Sky Solar install, where you can see the OEM shunt (top-right). Our hull is dated 2016 and yours 2018. Nothing wrong with the original install but I can only read status, when sync'd, and while watching the installed screen inside the Oliver.

The Victron SmartShunt has built-in Bluetooth and an app for reading on your phone.

The second picture shows the Victron SmartShunt installed (at battery ground), the simplest installation possible. I have revised my installation since, after installing the Victron Multiplus II Inverter/charger, where I have it at the inverter, but still closest to the B- battery ground terminal.

If I was to but a new Oliver Elite II (not happening for us, I'm a "always buy used" guy), I would have OTT install the solar array with wiring to rear dinette seat basement area (please NOT under the streetside bed) and I would install a Victron MP2 and pick from so many choices of LiFePO4 batteries on my own (Black Friday deals now 15% OFF). Battleborn batteries and Lithionics, good for the wealthy 3-6 years ago are now WAY bettered by LiTime (lowest cost), Epoch Essentials and others where 600AH cost <$2K or less! More info here (page up to first post)!

Our 2008 controllers are under the rear dinette seat. Very tight, but workable. I agree.
