Victron EnergySmartShunt Battery Monitor (Bluetooth) - Victron Smart Shunt - 6.5V-70V, 500 amp

Let’s get the only negative mention in this 5-star review of the Victron SmartShunt battery monitor out of the way; the Bluetooth range is less that other devices. However, try to find another shunt meter with Bluetooth. Aside from this characteristic, this is the best meter I have used. Why? Because numerous other meters do not provide usage trend data. The Victron gives the user trend data from 15 seconds to 180 days. You want this meter if it is important to understand the capacity of your batteries over multiple overcast days, and how long it takes to fully recharge after sunny weather returns. Example, monitoring my off-the-grid system using the Victron, I know that my 10kWh battery bank will remain above low voltage with three days of no sunshine. Also, it takes five days of full sun to fully recharge my LiFePO4 batteries. This level of monitoring capability is key to making sure a system is operating as it should. I have other Victron products on use and they all are high quality.

This is a must have, keeps me in charge of my battery status. Victron makes very reliable products. I wasted my money on a different shunt with hall monitor and it never gave me accurate readings. Spend the extra money and buy this.

Fantastic device, shows runtime remaining and allows proper operation if you install in a vehicle with a DC system connected to your battery. Way more accurate than using the inverter for calculating state of charge. Seems to be of very high quality just like all victron stuff, multi voltage, super versatile and overall I’d say it’s worth having in your system!

I have a few different Victron products and they all are top quality and well made. The bluetooth app works very well and is my favorite part of the product. Able to monitor batteries at all times.

So people keep assuming that when you buy a 100A battery it will give you 100A. if you use 1A it might give you 90-100Ah capacity. but when you erratically use a lot of power higher than 10% it would be wise to go through some testing and see where you fall for how you use your battery. if you are using 20 or 30Amps and haven't tested battery first it might only give you who knows 50A or 60A. so get yourself a separate ah tester that that can read amps going in and going out like the one I put a picture off. You can leave it on there until battery is completely charged and get a reading of how many amps went in then discharge it at whatever you are planning on using it and you will get a way way more accurate reading that you can then enter into your victron shunt and get more accurate readings. just don't go putting in whatever capacity the battery says because how many real amps you are drawing matters for accuracy or your charging and discharging stats will be off. now keep in mind that even battery monitors that come enbeded in the battery case could be inaccurate. I think companies do it on purpose to make you think you are getting more than what you pay for. please test your bank first but test it at real life amps that you will be using most of the time. I have a 48v bank made up of 2 150A lifepo4 batteries connected in parallel. and believe me power going in does not match what the monitors say. it's inflated. batteries will read 155A when fully charged but I know that through several amp hours tests done with a separate amp hour meter that its very inaccurate. it will only put out 135 Ah each bank running it at between 15-20Amps and hour. when I entered the correct AH total 270A of the battery to the victron parameters it is very close to when it shows its fully charged and discharged. on the other hand putting in the wrong value of just what the battery says without testing real amp power draw will be inaccurate. I wish this shunt showed acumulated amps used to charge battery, that would be immensely helpful in determining your real life capacity not just showing that it's charged. that way if only 100A were used to charge your battery but you have a bigger battery capacity this would tell you the condition of lets say a 135Ah battery like mine. and you yourself could determine how much capacity you are loosing over time. I do this myself occasionally by reading the separate meter that tells me how many Actual amps went in til its fully charged then comparing to actual amps being used til its completely discharged. i do this maybe every 2 to 3 months.

Although this shunt will work as a standalone monitor this is NOT its intended purpose. Victron system devices are meant to work together. When I bought this I was intending to use this as standalone using Bluetooth for monitoring. Like others have said, the Bluetooth is not great. Not only is the range very short but if you stay connected too long there will be frequent Bluetooth connection "losses". This is quoted because it's not just disconnected but when you try to reconnect the shunt will act as if it's still connected which the only remedy is to pull the small power wire.After a bit of learning more about Victron products, which are the best of the best, I've learned the ve.direct port is where all the magic happens. I already have a Victron SmartSolar 150/60Tr and now this shunt. I like to watch it CONSTANTLY and couldn't keep having to pull power on both the SmartSolar and the Shunt just to get it to continue working after Bluetooth fails. Also to note, when you pull the SmartShunt power to power cycle it it will lose it current SOC reading. It will fix itself once you hit Absorb and Float but that's not always helpful if you're already sitting as a low DOD.The missing magic box for monitoring everything, not just locally but also when away, is the CerboGX. This will allow you to connect the SmartSolar and SmartShunt via ve.direct then you can connect the CerboGX to either WIFI, for away monitoring, or connect to it via Bluetooth, for local monitoring, which seems to have a much more stable connection. Fortunately for me I have a Alcatel 4G router with ethernet port, which the CerboGX also has an ethernet port. Now I have the 4G router running off the LiFePO system and connected to the CerboGX so there's never downtime.The next step was setting up an account in the VRM portal which was insanely easy and now have SO much more details and trend graphs to monitor not only real time but MUCH more such as battery curve on discharge, solar voltage, solar amp, total amps used, battery charge cycles....the list is massive and has everything you could possibly want.Yes the CerboGX is a little costly, which caused much hesitation when initially choosing it, but after getting it and fully setting it up it has been WELL worth every single penny.If you're going to make the investment into the amazing Victron ecosystem it's best to do it the right way. You will not be disappointed and will only want to see just how much more amazing it can get....and Victron devices can expand further than your wildest imagination. I can't express enough just how much I initially wanted to go cheap but let me tell you....you will need to buy more components to any system and Victron makes this near dummy proof. Just read the manuals for each device carefully and don't go over any limits they set.That's all I have for you, happy solar harvesting!!My System:-10x Renogy 100w compact with their tilt brackets (5S2P)-Victron SmartSolar 150/60Tr (yes over-paneled to get to peak charge sooner)-Victron SmartShunt 500a-Victron CerboGX-2x Chins 12v300a (2P for 12v system/ gives me options to go 2S for 24v)-12v1200w Giandel (2400w surge for a few seconds)Considering 24v3000w Giandel and all I'd need to upgrade to a 24v systemthen many fuses and circuit breakers throughoutI know my pictures have a wiring mess but this is only due to not knowing what more I was going to add/change in the system. Once I decide if I'm staying 12v or move to 24v, and get the 24v inverter(they're MUCH bigger but all I need for this change) then I will be changing fuses/breakers and bundling all wires to fit my usually OCD/Perfectionist tendencies. And yes that is a raspberry pi screen I'm using for direct monitor from the CerboGX hahaI also included the VRM (Victron Remote Management) views from PC, 2 darker views, and the one from the mobile device app. Thought that might be helpful in understanding the value of the CerboGX and VRM (which a VRM account is free)
