Simarine-Pico-Battery-Monitor-Review-Installation-Van-Conversion-(Heading-1920px-)

The Simarine Pico Battery Monitor is actually much more than "just" a battery monitor. It has the ability to monitor multiple battery banks, current of multiple consumer devices, tanks, temperatures, inclinometer and barometer. Let's call it a SYSTEM MONITOR 🙂 It's an cutting edge product with an impressive smartphone-like-high-quality feel. While it's not essential to a working van electrical system, it's definitely a sweeeeeet upgrade for your van conversion if you don't mind the higher price tag. Here is everything to know about the Simarine Pico System Monitor!

1- In a Nutshell

1.1- Features

The Simarine Pico is completely customizable and expandable. To start off, you can use it as a battery monitor only:
House Battery Monitoring
Barometer (built-in)
Continue by adding any, or all, the following modules:
Consumers (battery screen)
Simarine Pico Battery and Consumers Monitoring
Blue means that the consumer is adding energy to the battery (charging). Yellow means that the consumer is drawing energy from the battery (discharging). The balance is displayed below the percentage (7.1A in the screen above)
Consumers (separate screen)
Temperatures
Tanks
Inclinometer

1.2- Components

In a nutshell, the Simarine Pico requires:
1- Simarine Pico Monitor
2- Simarine Input Module(s):

This is so the Simarine Pico can read the electrical input signal of the sensors (resistance or voltage), interpret it and display it for us humans.

3- Sensors (a.k.a. Senders)

This is to convert a physical measure (temperature, liquid level, angle, etc.) to an electrical input signal (resistance or voltage).

7.1- Installation Photos

Sensors

Temperature Sensors

There’s not much to say here… just install the temperature probe where you want to know the temperature!

(the blue sensors are Sensorpush wireless sensors. Read about them here)

Inclinometer Sensor

We installed our inclinometer under our kitchen countertop. It’s a flat surface and it’s easy to align the pitch/roll axis properly.

Inclinomter Countertop Van Simarine Pico
Note that this is NOT the Simarine inclinometer. Before 2020, you had to purchase a third-party inclinometer.

Tanks Sensor

1- Nature's Head Composting Toilet Liquid Tank

For the Nature’s Head liquid tank, we used a 9.5″ length sensor:

1- With the help of the gasket, locate where to install the sensor. mark the center for drilling and mark the outside diameter (to help position the sensor later):
2- Drill using a 1-3/8" hole-saw:
3- Find the correct alignement of the gasket on the screw holes, then apply a bead of Silicone II around. Do not let silicone stick to the sensor's probe! So Just a small bead of Silicone...

Note: Silicone is normally not required with these sensors, but it’s an extra step we’re taking because the screws don’t have excellent grip into plastic)

4- Insert the sensor and apply a small drop of silicone into the screw hole:
5- Use stainless steel metal screws (not the bolts provided with the sensor). Do the final torque by hand, or else you will damage the plastic and have poor grip (= possible piss leak).
6- We used these electrical quick connects for easy dumping of the tank. They're super easy to connect/disconnect (nice!), but they're not true crimp connectors; if you pull too hard on them, you might break the wire loose from the connector...
2- Grey Water (4 gallons Aqua-Tainer)

For the Aqua-Tainer, we used a 8.0″ length sensor:

The procedure is exactly the same as for the Nature's Head. But we used extra Silicone because the surface is not flat and the plastic is quite thin (screws don't have very good grip). We were worried it wouldn't work, but it does!
3- Fresh Water (25 gallons)

Here we have a straight surface and quite thick wall, excellent!

We used a 15.0″ length sensor (but check with your own tank):

We kept the most expensive (and difficult to replace) part for the end. At this point we're getting good at this 🙂

Simarine Modules

We won't win the cable-porn award, but our main electrical cabinet is super compact (space saver!) and that makes it very challenging to work in it...

(Note that the SC501 and SC301 shunts have since been replaced with the SC503 and SC303, connections might differ slightly)

8- Our First Impressions

After some time using extensively the Simarine Pico system, we can say it delivers! Sweeeeeet!

8.1- The Pico Device

Build Quality

Simarine is doing very well in the hardware department… With an anodized aluminium casing and a Gorilla glass, the Pico has an “Apple-like” feel, a classy look and is a real pleasure to use.  Because of that, we often find ourselves touching the screen to control it… Nope, it’s not touch-screen.

We build our van in 2016 and it’s the third monitor we’re testing. Battery monitors have come a long way!

2016:
2018:
2019:
Simarine Pico 1

User Interface

We think the user interface is stunning. In fact, it’s the first thing that caught our attention when we saw it first on a Norva van. The menus look clean, information is well displayed and the settings are easy to find.  This thing is definitely an eye catcher and it will probably find its place in more and more in high-end vans and RV.

Only one complain here: the only available mode for the inclinometer is “line”, while on the app the Campervan mode makes it much easier to read:

Simarine Pico Inclinometer

Also, the inclinometer can only be calibrated within the iOS or Android app, not within the Pico device itself… not sure why, but hopefully it changes in the next firmware updates.

Monitoring Performances

The temperature readings are super close to our Sensorpush wireless sensor, nice! The battery SOC, the consumers, the tank levels seem accurate as well; so far so good!

For some reasons, the voltage and temperature readings was TOTALLY off when plugged into the SC501 or the SC301. If plugged into the SQ25T, no problem…

A disappointment is the inclinometer which seems all over the place; we just can’t trust it. But the problem is not with the Simarine Pico, it seems to be the cheap “third-party” inclinometer we chose… We totally avoided “cheap chinese” product so far in our van build, except for our radio and the inclinometer; in both cases the products have under-performed. We’ll be on the search for a proper inclinometer sensor soon enough!

8.2- The Smartphone App

The App is an excellent complement to the Pico device. It makes the initial setup of the Pico MUCH easier and faster than doing it from the Pico’s screen. The displayed menus are very similar than the Pico and the settings are presented in the same order, so it’s super easy to find everything.

The iOS app seems to works flawlessy, but we had a hard time figuring how to use the Android app (our phone just couldn’t establish communication with the Pico). The only way to make it work is to set the Pico in STA mode: instead of creating it’s own WiFi network (you read it right: the Pico communicates via WiFi not via Bluetooth), in STA mode the Pico join an existing router (in our case, our Verizon JetPack). Once setup this way, we could use the app on our Android phone.

8.3- Product Improvement Wishlist

Here is a nice comprehensive list for you, Simarine! 🙂
Here is our workaround for the fact that there isn't a "screen off" button:

8.4- Victron Battery Monitor vs Simarine Pico Monitor

Which one should you choose?

We spent over a year testing the Victron battery monitor:

Here is our recommendation:

Get the Victron
Get the Pico

Hello! We’re Isabelle and Antoine 🙂 In 2017, we sold our house (and everything in it), quit our engineering careers, and moved into our self-built campervan. We’ve been on the road since then, and every day is an opportunity for a new adventure; we’re chasing our dreams, and hopefully it inspires others to do the same!

  1. Allo Isabelle et Antoine
    Merci pour toute cette info !
    Je pense installer un simarine sur mon prochain van.
    Celui-ci pourrait remplacer le controler webasto au complet ???? (Vous indiquez la temperature et pico se charge du reste ?) Ou bien on doit tout de meme avoir un controleur webasto en plus ?

    Reply
    • Ca prend définitivement le contrôleur Webasto.
      Le rôle du Simarine est de vous INFORMER sur les températures actuelles (Intérieur, extérieur, fridge, etc., selon vos besoin); tout comme, par exemple, il vous faudra aussi un contrôleur de charge pour le solaire.

      Bonne chance!

  2. This is exactly what I was looking for! Y’all are amazing. In the wiring diagram, what does [1a] mean on the red wire from the shunt to the battery? What size wire gauge do you use for that?

    Reply
  3. Thanks for all the information on this. We have one simple question: what is the difference between “bezel” and “panel mount”? That’s how they are described on Amazon; the Simarine website says “standalone” and “panel mount.” We want to install it into the wall like yours so is that panel mount?

    Second, the Simarine website sells the pico covers “for standalone.” So I’m wondering if your built-in is panel mount, then the cover won’t work?

    Thanks for your help!

  4. It looks like the answer is yes you still are happy with your Pico system but after reading all the Amazon reviews I just want to verify that your experience continues to be good. Looking forward to a “second thoughts” section soon. Thanks for all you do!

    • The smartphone app has several bugs, they are currently working on V2 app which hopefully address that. That being said, the monitor itself works just fine, so yes we would buy it again!

  5. Hi guys,
    Thanks for this great piece. I am confused about where the Simarine fits into your overall electrical system. It looks like the fuse block in your diagram is used only for the modules for the Simarine. That fuse block appears to be connected to a positive and negative bus bar.

    Are those bus bars the same bus bars as your MPPT charge controller, batteries, inverter? You had an extra slot available for this extra DC fuse block? Or, do your van have TWO positive and negative bus bars?

    Hope that makes sense. Everything else is super clear here, but that one piece is blocking our progress.

    Thanks!
    Dom

    Reply
    • We have one positive bus bard and one negative bus bar. According the ABYC standard, you can stack up to 4 terminal connectors on each stud (16 possible connections).
      For your information, we have more 12V loads connected on the fuse block that aren’t going through Simarine shunts…

  6. Hello wonderful van builders,

    I’ve been digging deep into the simarine Pico system and have one question, and a little background info. I want to use the Simarine inclinometer for my van, but was thinking of using another 3rd party inclinometer to measure a tilting solar array, in one of my extra voltage slots and realized the one I found is a similar WitMotion sensor you used.

    Could you clarify which version of the WitMotion sensor you used (RS232 or RS485?) and how it’s connected to the shunt/which wires are used?

    I can’t thank you enough for how in depth your guides are or how helpful this website has been in planning! I absolutely plan to send some love your way once I start building.

    Best,

    Steve

  7. Hi Isabelle and Antoine,

    You mention on your battery monitor post that you prefer the Victron monitor then on this post you mention you use the Simarine to also monitor the system. I was just curious if you’re using both Victron and Simarine for monitoring? If so, how is your system wired for all those shunts, do you have a victron shunt as well as all the Simarine shunts?

    Thanks!

    Reply
    • Out of curiosity, where did you read that we prefer the Victron?

      We like the Victron BMV-712 monitor and this is the one we recommend as entry-level monitor (good for most users, as it is more affordable). But, we are a little nerd; we like the ability to monitor more than just the battery (like tank levels, temperatures, etc) and this is why we like the Simarine monitor. We don’t use both, but each system would need its own shunt if we wanted to use both (for communication display).

      Reply
  8. Hey guys, I have a Simarine Pico as well and just wanted to see if you could clarify something for me.
    Are you running your + wire from the MPPT solar controller through the SCQ25 module through two input ports (1 and 4) then out to the positive bus bar?

    I have two panels in series not parallel, creating 40.4v and 8.91a. (I believe you guys are running in parallel so will probably have 20ish volts and 20ish amps.)
    The inputs can share the load right, so I could do what you have done and split my + into two and run it through two ports.

    Any comments or advice greatly appreciated, though I appreciate you aren’t electricians, but you do have some experience here!

    Reply
    • How you wired the solar panels doesn’t impact the connection with the SCQ25 (solar panels wires go directly in the MPPT solar controller). The SCQ25 shunt must be connected between the MPPT solar charger (output) and the battery (bus bar). So depending on how much current your MPPT solar charger can deliver, you must split the wire to make sure no more than 25A will go through one input/output of the SCQ25. And just a reminder, splitting the wire in 2 wires will divide the current in 2; eg Victron MPPT 100|30 can deliver up to 30A, so splitting the wire in 2 will make sure not to have more than 15A (approx.) in each wire. Hope this all makes sense to you 🙂

      Reply
      • Hello Isabelle. I also want to monitor my 30A MPPT controller with the SCQ25. Currently I have 8 AWG wire out of the MPPT then to a 40 amp breaker (as per your wiring diagrams) then to the positive buss bar. Because the wire will be split to go through two ports of the SCQ25, could I use two 14 AWG wires (using your wire calculator @ 15A) to go from the MPPT to two of the SCQ25 ports then from the SCQ25 to the 40 amp breaker (stacking both 14 AWG wires) then 8AWG from the breaker to the positive buss bar?

        Many thanks,
        Marcus in Taos

        Reply
  9. Do you not think you could add a simple switch between the positive bus bar and the sicom splitter to turn the monitor off? And if you turn if it off, would you reset the whole unit? Annoying you can’t turn the screen off…

  10. Hi Isabelle and Antoine,

    First I want to say thank you for your website…all that information helped me a lot in my conversion!!! It’s pretty impressive all the time you spent on each detail and so…the time I saved because of that !!!

    I bought the Pico blue package + SQC25T + SC301 and I’m now planning my installation. After reading all the information on this page I have 1 (or more)question(s)… what information do the Pico give you by connecting the solar charger on the consumer (2x) ports? Why 2 ports?…I only have 1 port available (I will monitor : 2x Maxxfans, 1 Novacool fridge, 1 Nature’s head, 1 Webasto, 1 lightning and the fuse block….)…

    Thanks for helping me !

    Reply
    • As our Victron Solar Charger 100|30 can theoretically deliver more the 25A (which is the max per SCQ25T port), we had to split into two inputs/outputs. SCQ50 would have been more appropriate but didn’t exist when we did our monitoring system.

  11. Hey!!

    You guys rock!! We couldn’t have done our van build without you!

    We have the pico, we can connect to AP WiFi. This is great locally at the van.

    Is it possible to connect the pico to a jet pack so we can view the pico while away from the van. We want to monitor the temp of the van so we know our dogs are okay.

    Thanks,

  12. Hi!

    Thanks a lot for making this webpage. It is helping me plan a lot, and I am trying to use your affiliate links whenever I can to support you.

    I have a question about the 7.2- WIRING DIAGRAM. In the diagram, the things that come from the fusebox are connected to the SCQ25T module through the “IN” port, but in the pictures above I believe they are connected to the “OUT” ports?

    Then a note; in the wiring-diagram-High-Power, the battery shunt shown if you choose Simarine is SC301. If you then choose to have 4 batteries it is a bit confusing as but as the shunt only goes to 300A. So do I understand it correctly that if your battery bank exceeds 300A you should go for the SC501 shunt? And how do you know which shunt to get for the inverter?

  13. I love your write ups. So detailed and it soothes my ocd. Haha. Anyways, I have a 1990 vw Vanagon and I have a dual battery setup. I’m running a dometic fridge, diesel heater, air compressor (when needed) and a couple auxiliary lights. I have the battery installed but I’m looking for a monitor system that will show the charging for both my house and starter battery, the amps per hour that I’m burning, how long till my house and starter battery ate charged etc. would you recommend the Pico one? Please let me know. Thanks!!

    Reply
    • The Victron BMV-712 would fit better for your needs I’d say, but it only has the ability to display the VOLTAGE of the starter battery (not the % and everything). But do you really need all that info for the starter battery anyway? If yes, then you might look at the PICO (with two shunts for two battery banks).

      cheers

  15. So overall, would you say you’re pleased with the Simarine Pico Standard package and would choose to install that over the Victron Battery Monitor?

    Personally, I love the high-class look of the Simarine and if it monitors more than the Victron monitor, it seems worth it.

    By the way, I have been so grateful for all your tips on your site! You’re so thorough and I can tell you love the engineering side of the vanbuild process.

  16. Antoine,
    Super helpful instructions. I’m running short on Sicom cable. Tried a regular 4 wire phone line RJ11 after trimming the jack head to the right size. Also tried an RJ9 cable. It doesn’t recognize it even though it seems to snap into the slot perfectly. What exactly is this Sicom jack? Can I buy the cable locally at a Walmart/Home Depot?

    Thanks!

  17. Hello,
    Love the install and review.
    Simarine do have a inclinometer which is the “Simarine SDI01”. It uses the SiCOM connections which is sweet as it is very easy to connect. Also its range is Measuring -30°~+30° which is small and therefore more accurate with a Resolution of < 0.001 °.
    Here is the Australian retailer I use but I am sure it would be available there. https://www.safiery.com/two-axis-inclinometer-pitch-and-roll-sibus-interfa

    Hope this helps,

  18. Hello
    If we buy the Simarine controller do we still need the Vitron digital multi controller and the Vitron MPPT 100 charge controller?

    Thanks so much!

    Reply
    • The Simarine role is to MONITOR what’s going on, and the Victron MPPT is the actual CHARGER; so you need both.

      Not sure what you mean by the Multi controller?

      Reply
  19. Did you split the positive wire coming from your solar charge controller to connect it to two inputs and outputs on the SCQ25T? How did you do this if this is the method you used? Thanks!

    Reply
  20. Question: If your Inverter was actually a combo Inverter/Charger (for charging house batteries from shore power), would the SC301 Shunt, in the same location, measure 120V loads in Inverter mode but also measure input current into the house batteries in Charger mode?

    Reply
    • Yes, your monitor would display INPUT (charge) – OUTPUT (load). So let’s say you charge at 60A and you draw 9A (computer or whatever), the monitor would display 51A.

      Hope that makes sense!

  21. Salut Antoine. Your site is awesome. Helped install Pico myself. Many thanks. Question, I notice an Auto Off feature in the menu on the Pico but there’s no explanation in the manual. I suppose it was added in a recent firmware update. You can set it for a certain amount of time but I’m unsure if the system continues to monitor battery usage when off. Do you know? As sleep only dims the screen, I’m hoping this feature make the system keep track of battery drain so I can use it to avoid having the screen on all the time, especially when our RV is not in use. Thanks for your help.

    Reply
    • Hi Tony,
      The limit is not 300Ah, it is: 300A. So it has nothing to do with your battery bank size, it’s actually the current. For example, a 3500W draw over 300A so that would be too much. If that’s an issue, you can go with these shunt instead of the “standard” ones: SC501 or SC502T (up to 500A).

      So yeah, 4 x 110Ah lithium batteries will works just fine 🙂

      Reply
  22. Did you hook the solar charge controller into 2 of the 25A connections so it wouldn’t go over the 25A max? Was this easy to correct and combine in the app when setting up the system?

    Reply
  23. Hi Antoine!
    Great review. We’re considering the Pico for our build, but are wondering – is it possible to measure a Sterling 60A b2b input? (would that require another SC301 shunt since the SCQ25 only goes to 50A with 2 slots?).

    Thanks,
    Peter W.

  24. Hey! Love this system and planning to install on my next build. Wondering though, in looking at your comparison to the Victron system did you consider the color control GX modules? It’s obviously great that the Pico unit combines the display unit with the battery monitor so that it’s all in one spot, but the CCGX unit from Victron offers pretty similar plug and play functionality when it comes to additional monitoring inputs (tanks, temps, other batteries, etc.).

    Really, in my mind, apples-to-apples comparison would be between a system built around the victron CCGX and a fully kitted-out Pico system. Would be interested to hear your thoughts there.

    Great article though and super helpful in navigating the connectivity of each shunt module!

    Reply
    • Hi Dennis,
      I’ll be honest, I don’t really like the look of the GX… I think the Pico look more “classy” and high-end; that’s what I want to see in 2019 in my van! Sorry if you expected an in-depth analysis, but I haven’t look into it.

      Cheers!

      • Thanks Antoine! No worries, I definitely agree that the Pico is a much sexier monitor than the GX, was just wondering if you had looked into them at all.

  25. Are you planning to add propane level monitoring?

    Love the system. Been watching it for about a year now hoping the price would come down and/or an API would be released to bring in data from my Xantrex & Kisae units onto a unified display.

    Reply
  26. Awesome! If I read it right, could you measure the input current from each charging source (solar, acg, etc)? My experience with the victron was that in winter with low sun the monitor thought the battery was charged (based on the acg current profile) but it was actually just cloudy, and not much current from the solar. Could you input “100%” charged criteria for multiple charging sources?

    Reply
    • The Simarine is different than the Victron: there is no synchronisation to 100% based on voltage/current conditions. It’s all dealt with by the “smart” algorithm… So far, it’s seems pretty accurate (especially with LiFePO4 I’m guessing, since there is no Peukert effect). (note: there is still the possibility to do a manual synchronisation; we’ve done it only once right after we finished with the installation and we knew the battery was full).

      Reply
  27. Does this allow, like the Victron, the ability to close a switch when some condition (like temperature) goes above/below a set value? I’d like to use a monitoring system to stop charging a battery if: 1) temperature too low, 2) temperature too high, 3) battery voltage too high
