Connecting

SiCOM data cable - For the SiCOM connection use the supplied cable. If not possible, use the following table to determinate
the right cable type.

PICO connects to the SiCOM bus via attached Splitter, which is a SiCOM bus entry point for other devices and the power
connection. Splitter must connect to the power source (6-35V) with the red/black cable. It is recommended to connect the
power cable behind the main switch, so you can power off the complete system, although the total power consumption of
the system is very low (usually <100mA at normal operation).

5.2.1

You can find the information of all the latest Simarine Digital shunts / modules on the website:

https://www.simarine.net/manuals

For 12V and 24V systems you can wire your shunts on either the positive or the negative side of the system. For higher
voltages (above 35V), wiring to the negative side is mandatory.

6.5.1

In the settings menu navigate to DEVICES > BATTERY

Select “Add new” and fill in the requested data.

·

·

·

·

·

Adding a new battery

NAME - Name the battery/battery bank accordingly (STARTER, SERVICE, MAIN, etc.)

TYPE - Select the battery type (Wet low maintenance, Wet maintenance free, AGM, Deep cycle, Gel, LiFePO4)

C/20 - The declared capacity of your battery.

C/10 - Input only if the rating is explicitly provided by the manufacturer of your battery, otherwise leave it as “Not Set”.

C/5 – Input only if the rating is explicitly provided by the manufacturer of your battery, otherwise leave it as “Not Set”.

When configuring a battery bank, you have to input the ratings of the battery bank as a whole.
Example: if you have 3x 100Ah batteries connected in parallel, C20 = 3x 100Ah = 300Ah. The same rule applies for C10 and

C5 ratings.

For lithium batteries, only input C20 rating and keep C10 and C5 as “Not Set”.

·

VOLTMETER - Select a voltmeter connected to the battery. Only voltmeters that are not already used elsewhere in the
configuration are displayed on the screen.

Note: Do not select PICO Internal - as this is not a calibrated voltage reading.

25

Basic Setup

6.

·

AMMETERS - Select the current sensor connected to the battery. You can select only current sensors that are not already
used by another battery configuration. For a battery configuration without a shunt (voltage-only), leave ammeters empty.

·

TEMPERATURE SENSOR- Select a temperature sensor if you have one installed and configured.

·

RANGE - Adjust the presentation of the current reading for the battery. By default the value is set 100A and it means, that
the bar used for visually representing the measured current will be displayed as full at 100A (the default range is between
0A - bar empty and 100A - bar full).

EN

·

INSTANCE - An identifier for NMEA2000 network. For use with NMEA2000 each battery has to have a unique instance
field. Confirm and save the bank configuration with button.

·

DELETE - With this option, you can delete the selected battery

26

Basic Setup

6.

6.5.2 Advanced settings

Advanced users may adjust some additional battery settings to customize the battery data display. It is not suggested to
change these settings – the defaults should be suitable for all battery types.

·

TTG AVG – averaging interval for calculating TTG (time-to-go). “Short” means that TTG will respond to the change in
current more quickly, and “Very long” means that TTG will respond to the change in current more slowly.

·

TTG SOC MIN – Represents a declared offset from the actual battery state. Set by default to 20% means that when
PICO will display the remaining state of battery to be 0%, the actual state of the battery will be 20%. In case you want
to compare PICO readings to internal battery monitoring system provided by the battery manufacturer, it is important
to set this parameter to 0%, which will give you the absolute state of the battery.

·

CEF – charging efficiency (%).

·

DISPLAY TYPE – “Detailed” display type also shows the amp-hour counter on the batteries screen.

·

BATTERY FULL SETTINGS

Any changes under these settings may cause huge offsets in precision of monitoring your battery. These settings should
only be altered in extreme cases, such as if your battery is old and dying and can no longer hold the same amount of
charge that is declared by the battery manufacturer. In that case, you can alter these settings, so that PICO can correctly
determine when the charge in the battery reaches its full capacity.

-

Advanced users

EN

These settings are only relevant when the battery is monitored using a shunt (current + voltage).

Here, users may set additional battery full parameters, which will be used by PICO to help determine when the battery is full.

Example:

27

Basic Setup

6.

- If you have a 13,8V 100Ah battery, then you can use the settings from the picture above.

- System voltage (12V) x factor (1.15) = 13,8V -> your battery full voltage.

- Battery capacity (100Ah) ....... 1.0 is a % factor of the battery capacity (1.0 = 1Ah = 1%).

- Time -> This setting is a determined time interval for how long both conditions (voltage, current) need to take place for
the battery to be determined as full (100%).

Set manually -> Use this calibrate the batteries state of charge to 100%. You should use this functionality only when the
battery is actually full. Once you select this option, the PICO will note the battery as full and after that it will rely on the
calculations based on the input/output current readings.
Execute the calibration when you are sure that the battery fullness is at 100%.

PICO uses an algorithm which tries to find the starting state of charge of the battery after the configuration. For
lithium batteries it is highly recommended, that you calibrate the battery manually after you configure it.

Current sensors configuration

6.10.1 Current sensors

List of all current sensors (shunts). Connected shunt modules are added to the list automatically. In this list, you can view
real time readings (amperes) for all connected current sensors. By selecting a certain sensor, you can view or change its
settings.

33

Basic Setup

6.

Pressing the enter button will open a settings screen for the selected sensor.

NAME - Assign a display name of the current sensor.

RANGE - Adjust the presentation of the current reading for the current sensor. By default the value is set 100A and it means,C
that the bar used for visually representing the measured current will be displayed as full at 100A (the default range is betweenC
0A - bar empty and 100A - bar full).

EN

REVERSE CURRENT - For consumers the current reading should be a negative number measured and for generators itC
should be a positive number measured and displayed on the CURRENT SENSORS screen. In case of reverse wiring, theC
situation might be exactly the opposite. This can be resolved either by rewiring the shunt or - easier - by toggling this option.

ADD CURRENT - Determines if the measured current should be used in the calculation of the state of charge for the batteryC
to which this shunt is assigned to.

In case there a multiple shunts in the system it is important to watch out for a possible "double current" problem (when
the same current is calculated twice). This happens if the same current passes through multiple shunts. Example: a fridge
is monitored individually with a dedicated current sensors, but the same current passes also through the main battery
shunt. In such case, we should configure the monitor so that it will calculate only the current of one of the sensors, while
the purpose of the other sensor is purely the convenience of the user to see the device's consumption (individual device
monitoring).

34

Basic Setup

6.

BATTERY - Here you can assign your shunt to a battery. More common way is to assign shunts to a battery through the
battery configuration screen.

DISPLAY SEPARATELY - If enabled, the shunt will be displayed in separate screen, even if the shunt is assigned to a battery.

DISPLAY PRIORITY - Set the display priority of the current sensor. Here you can also hide the current sensor.

DEVICE - Displays a full ID of the current sensor. This is read only and it will not change even if you rename the sensor.

MERGE WITH - Gives you an option to merge the sensor with another sensor. That way you tell PICO to consider the
readings of two current sensors as a reading of a single device.

!

PICO’s algorithm for calculating state-of-charge (SOC) is not
a simple Ah-counter. It is constantly monitoring battery current, voltage, and temperature. The data is
compared to the internal battery model, and its parameters are constantly being adjusted so that the model
fits the actual data. The algorithm needs some time to adjust the parameters, and it will improve accuracy
during the first few cycles.

You can switch between different screens by pressing the up or down arrow buttons. There will be a separate screen for
each battery with at least one connected current sensor (shunt). Multiple batteries without a current sensor (measuring
voltage only) may join on a single screen.

Up to four tanks and four thermometers will join on a single screen. If there are more, they will divide into two
or more screens. There is also a separate barograph screen on PICO.

Screens for showing battery data differ depending on how many current sensors are connected to a certain battery. If the
battery connects only to a voltage sensor (without a current sensor), the battery name, approximate state-of-charge (SOC)
and current-voltage are displayed.

The calculation of SOC takes some time, so it may not be shown immediately after power-on.

Up to three batteries without a current sensor can be shown on a single screen. If there are more, they divide into two or
more screens.

If the battery is connected to a voltage sensor and a current sensor (shunt), some additional data is displayed: time to
charge/time to discharge, current (amps) and voltage.

Monitoring a battery with a shunt, gives you the highest possible precision. For lithium batteries using a shunt is
mandatory.

Time to discharge is calculated by using an average consumption during a period of time. If there is more than one current
sensor (shunt) connected to the battery (e.g., for monitoring different consumers or generators, connected to the battery),
their data (amps) is also shown on the battery page.

Tanks screen

Tanks screen shows the current level of connected and properly configured tanks. Up to four tanks can be displayed on a
single screen. If there are more, they divide into two or more screens. For each tank, you can find its name, graphical
representation of the current level, and numerical values of the current level as a percentage and as the volume unit (liters,
gallons).

Depending on the selected tank types, they are represented with different colors.
If the tank sensor isn’t selected in the tank settings or the sensor got disconnected from the PICO system, the “OFFLINE”
symbol will appear on the screen. If this situation occurs, check the sensor setting of the tank.

If the sensor is selected, check if all the cables are properly connected.

Temperatures screen

Temperatures screen shows current temperatures of connected and correctly configured temperature sensors.
Up to four temperature sensors can be shown on a single screen.
If there are more, they divide into two or more screens.

For each sensor, you can find its name, graphical representation of the current temperature, and the numerical value of the
current temperature in the chosen unit (°C or °F).

If the temperature sensor is not selected in the temperature sensor settings or the sensor is disconnected from the PICO
system, the “OFFLINE” symbol will appear. If this situation occurs, please check the temperature sensor setting. If a device is
selected, please check if all the cables are properly connected.

NOTE: In case your temperature is displayed as a constant -13°C (8.2°F) or some other high or low value, then the
most likely problem is that you do not have a correct sensor input selected. Selecting any sensor input to which no
temperature sensor is connected to, will result in such readings.
