    Minor technical correction, shunts are not the only way to measure consumption.
    I've had a Hall Effect monitor for 2 years. It too is bluetooth but goes to a dedicated screen, which I find simpler. It has similar reporting and relay features for under $50 complete.

    Marc,
    Once you have conditioned your average discharge rates to your Battery Mon, it would be nice to see how it calculates available charge remaining under current load conditions. That's when it becomes really meaningful.
    The two systems work incredibly well together. Thanks.

      @@GrandAdventure I like the setup. But for me, the new Ford Powerboost with 7.2kw onboard power generation solves all these issues. It uses the FordPass app with FordPass connect to accomplish all the connectivity.
      When the 3.5 Ecoboost fires up, you can hardly hear it. It is much quieter that most RV generators making it a viable option for boondocking. Plus, you get the use of your RV air-conditioner... a huge plus, especially if your working inside during the summer, like you do.

It just engages the belt drive attached to the crank shaft and turns over the engine silently. You don't even hear the engine start. Which means that when the regenerative electric motor in the transmission needs to start charging the onboard lithium ion battery, it does so without making much noise at all.

    I bought 3 x 3y old used but tested lithium ion batteries (with 5 to 7y life left), 2 x 120w mobile foldable solar panels that I can place anywhere, 2 x $17 charge controllers, a $30 bluetooth battery monitor that connects to my cell phone, and self-wired everything to be able to charge either / or both at the same time my house batteries and / or chassis battery. And while not perfect, it works pretty well and I am happy. Total investment approx. $1,300.

    Nice monitor and presentation. I'm also looking at the Victron 500A SmartShunt which is similar. I can see why you went the way you did for the integration with the Wnisper system.
    I looked at the mannual wiring diagram and it appears to have the shunt on the positive side of the ciruit rather than the negative side. I guess it would work but I have never seen that. Having all that exposed metal on the positive current doesn't seem like a good idea to me. I noticed you and The RV Addict wired the shunt on the negative side and it appears to work fine.

    • @GrandAdventure
      @GrandAdventure  3 года назад

      Thank you Bruce! Despite that wiring diagram in the manual the original Thornwave Labs PowerMon that we used can be installed on either side of the circuit, positive and negative, but its internal shunt has a limit of 60A which is why we chose the original PowerMon (to install on the negative side) but purchased an external shunt. They now also have available the PowerMon-5S www.thornwave.com/collections/smart-products/products/powermon-5s-bluetooth-battery-monitor-dc-power-meter-with-integrated-500a-shunt with an integrated 500A shunt that we initially planned to use because it will also integrate with RV Whisper, but the brain behind RV Whisper informed us that PowerMon-5S needs to be installed on the circuit's positive side. Knowing that, we chose the route that we did.

    A few questions. 1. I didn’t see in line fuses between the battery and shunt nor between the battery and PowerMon as suggested by the diagram on page 23. Are they needed? Does make it more complicated as I’m not ready to splice my battery cables. 2. What wire gage is acceptable from the Power Mon to the external shunt? 3. Will this work with two 12Volt batteries connect in parallel? Thank you for the video so far.

    • @GrandAdventure
      @GrandAdventure  2 года назад

      Dan, we didn't mount one between the batteries and shunt; however, we did mount resettable circuit breakers between our battery and inverter, and (subsequent to this video) between our solar panels and solar controller, and between our solar controller and our batteries. You only need small gauge wiring between the Power Mon and the shunt, as it carries little current and is a very short run. Yes, it will work with two batteries mounted in parallel. We actually now use it with four wired that way.

    How does the monitor know the sensitivity of the shunt to read correctly (mV/amps)? Shunt needs to be calibrated to get a linear output to calculate sensitivity. They are temperature coefficients that can effect the accuracy. Did you have to manually enter it?

    • @GrandAdventure
      @GrandAdventure  3 года назад

      Yes, on the configuration screen there's a place to enter the specifications of the shunt, including sensitivity and voltage range. That's all explained in the monitor's user manual www.thornwave.com/res/btdcpm_um.pdf if you're interested in taking a look at it.

  • @iairj84
    @iairj84 3 года назад +1

    The setup in the app is incorrect for your shunt (at least it was in the video) you need to adjust the shunt resistance and range based on your shunt. It's probably bidirectional 75 or 80mv and the manufacturer should have the resistance number or you can calculate it. As it sits you're not accurately measuring the input and output. It should show your effective range as around the shunt max amperage.

    • @GrandAdventure
      @GrandAdventure  3 года назад

      It is indeed bidirectional 75mv, but there's no such option in settings. The manual www.thornwave.com/res/btdcpm_um.pdf provides a configuration example on page 16 for setting the "Sense Resistor" and "Sense Voltage Range". However, one thing we didn't do until after filming was to set up the Battery Fuel Gauge, which was an absolute error on our part.

I believe for your shunt it would be resistance of .15 as best as I can tell with ohm's law.

      Jeff, Thornwave's prices have risen around $40 since we did this video. At the moment this setup would cost $139.99 plus an inexpensive shunt.
      However, the Thornwave uses Bluetooth, so the equivalent Victron unit would be the BMV-712 which is around $100 more, and not the BMV-700.

    Can any bluetooth battery monitor be installed onto the Whisperer or only PowerMon?
    Did you take the negative from the closest battery of the three lithium batteries and did you also take your positive feed from the same battery?
    On the monitor I have (from a different manufacturer) it can have a feed from the positives of each of my two batteries.
    I’m not sure why since both positives go to the same place, unless it is just for somehow monitoring each battery.

    • @GrandAdventure

      Ram, the developer of RV Whisper has to a) have access to the Bluetooth communication protocol of the device to be able to program RV Whisper to work with it, and b) he has to write the programming for each of those devices. For that reason it presently works with just two devices for battery monitoring: the Thornwave PowerMon that's showcased here, and what RV Whisper sells as a "Battery Mole" which is a simple voltmeter. A voltmeter comes with the limitations explained in this video, so even though we have one we upgraded to the PowerMon in this episode.
      Our batteries are tied together in parallel, so it doesn't matter which battery we hook to the monitor -- the monitor sees all three separate batteries as one big battery bank.

    My issue with the bluetooth devices is obsolescence, either planned or un-planned. Company goes out of business, so no upgrades to the app, you get a new version of Android or IOS and bam!!!! totally useless hardware. Company comes out with a new model, wants you to buy it, so they develop a new app, old one is obsolete, again, you are outta luck. Now, if you have a built in display, and possibly an app also, thats OK, the equipment is still useful.
    Other issue is having a bunch of apps. You got a Mopeka tank app (yes they have a bluetooth monitor too), and this power monitor app, and possibly an app to go with a Hughes portable EMS for your shore cord, possibly one or two more. Becomes kinda a PITA. Now, if someone would develop a single app that handles all of the common Bluetooth items in an RV, that would be great, even if you had to pay for it.

      As far as the second paragraph, that's where RV Whisper comes in. That ties everything together in one place: not only the Thornwave, but also the Mopeka, Hughes Power Watchdog and Mopeka too. It's the single app that handles all of the common Bluetooth items that you're wishing for.
