Simarine Pico Blue
  1. When the shunt is mounted in the battery's NEGATIVE line, the state of charge (SOC) of a 12, 24, 36, 48, 60, or 72 volt battery system can be monitored. ONLY with 12 or 24 volt battery systems, the shunt can also be mounted in the battery's POSITIVE line.
  2. In addition to other measuring modules, up to 6 shunts can be connected to the PICO Standard or PICO Blue, which can independently detect the state of charge (SOC) of different battery systems, e.g. of a 12 volt and a 24 volt battery bank.

Battery types

  • Do PICO and PICOone devices support lithium-ion batteries?
    The PICO system is compatible with LiFePO4 batteries
  • Which battery types are supported?
  • Generally all lead / acid batteries such as AGM, GEL and LiFePO4 batteries

    Firmware update

  • Is there a smartphone app?
  • Yes. The Simarine "PICO Battery Monitor" app is available for free on the Google Playstore or App Store.

  • Can I update the PICO firmware myself?
  • Yes. The PICO product family is constantly improved and updated with new functions. It is thus recommended to keep the PICO firmware up to date.
    Update can be done with the "PICO Battery Monitor" smartphone app . The app can be downloaded as described above.

    Use the serial number of the PICO to create the WLAN SSID and password. You can find the serial number on the back of the PICO display or on the front side of the original packaging or in the PICO system menu (PICO SETTINGS -> SYSTEM -> System Info.).

    If your PICO serial number is "12345678".
    Your SSID is: Pico5678
    Your password is: pico1234

    Before updating the firmware, update the "PICO Battery Monitor" smartphone app via the respective store and then follow the steps below.
    1. Install or update the "PICO Battery Monitor" app on your smartphone, turn on the WiFi connection of your PICO device and connect your smartphone to the PICO WiFi hotspot (PICOxxxx).
    2. Start the "PICO Battery Monitor" app on your smartphone. Open the "Settings" menu and click "Update PICO Fimrware" to put your PICO device into upgrade mode.
    3. The update process takes less than a minute. Then your PICO restarts.

    Consumption and generator monitoring

  • Can I monitor the power consumption of my inverter with the PICOs?
  • Yes. Using the SC300, SC500, SC302T shunts, the PICOs accurately measure the power consumption of individual large consumers such as inverters, bow thrusters, windlasses, etc. With the SCQ25 module, currents up to max. 100A can be monitored just as precisely. You can read the exact current consumption values and a consumption history from your PICO display.
  • I'd like to know if my solar panels generate enough electricity to power a refrigerator. How do I get this information?

  • Simply integrate the Simarine SCQ25 module (4 inputs, each with a power of 25A, individual inputs can be summed via the software) into your PICO system.
    The SCQ25 module provides accurate power readings generated by your solar system or consumed by your refrigerator.

  • Can the PICO devices show how much power is generated by my solar panel?
  • Yes. With the PICO battery monitor, you can measure how much power your solar panels or wind generators supply. This is also a very good tool to detect malfunctions of individual energy sources.
    If, for example, your solar panels get dirty and therefore produce less power, you can easily and conveniently see this on your PICO display.

    External protocols

  • Do PICO devices support CI-BUS (special Caravan data bus system)?
  • Not yet. A CI-BUS support is planned.

  • Do PICO devices support NMEA protocol?
  • Not yet. NMEA0183 and NMEA2000 support is under development.


  • Is it possible to use more than one PICO display on one battery bank?
  • This option is being planned and will be part of a future firmware update.

  • Should I use a shunt to monitor battery voltage, battery power and battery temperature? Or is it just enough to monitor the battery voltage?
  • To accurately monitor your battery bank, a shunt is required. This is not only to provide data enthusiasts information about the current status of the battery bank, it is for your safety!

    We recommend shunts when using large consumers, such as B. bow and stern thrusters, and windlasses. Such consumers can significantly discharge their batteries within a very short time.
    This can mean, for example, that batteries could be damaged quickly if they are not sufficiently charged.

    If you just want to monitor the battery used to start your engines, in most cases it is enough to simply monitor the battery voltage.

  • What is a battery bank?
  • If two or more batteries are used in a parallel or series connection, these batteries are called battery banks.

    Parallel connection
    If batteries are connected in parallel, capacity increases (Ah / ampere hours), while the voltage (Volt) remains the same.
    Three 100Ah batteries with a voltage of 12V are connected by a parallel connection. This results in a battery bank with a capacity of 300Ah at a voltage of 12V.

Flag of English meine Batteriebank hat eine Kapazität von 720A, aber PICO Blue kann nur bis 500A verwalten. Gibt es grössere Shunts?

Man darf die Batteriekapazität (Ladung) Q, die in Ah (Amperestunden = A*h) angegeben wird nicht mit einem maximalen Stom I verwechseln, der in A (Ampere) angegeben wird, verwechseln! You should not mix up the battery capacity, a charge Q, measured in Ah (amps hours = A*h) with a maximal electric current I, measured in A (amps)!

Hi Marco, in your inquiry are some essential details missing and your data regarding solar are not clear. Are the PV modules really switched in series or are they switched parallel? (3x Vmax in series = 59,4 V, 3x Vmax parallel = 19,8 V, am I right, all PV modules are the same type?) Tell me the short circuite current (Isc) or the max. power (Wp) of the PV modules. And I need to know: what are the max. charging or load currents, which have to pass the Pico's shunt. Max charging current could come from the alternator, max load current could be the current of a powerful thruster or an electric winch or an inverter. Pico sets use 3 different Shunts. One type can continously carry 500 A (6000 W @ 12 V) continously, the other 300 A (3600 W @ 12 V) and the third 4 x 25 A (4x 300 W @ 12 V). Pico allows to switch shunts parallel and add the resulting values by software. So eg. the 4x 25 A could be used for currents up to 100 A (300/600/900/1200 W @ 12 V). This case is an example of that we need from you very precise information about the equipment of the boat and the planned use of the pico in order to be able to recommend an appropriate set or other required components. Unfortunately we are not able to communicate in detail via this customer portal. Please send your detailed inquiry to I'm looking forward to answer then all your questions.
