Your system includes components from Victron’s
“Smart” energy line with Bluetooth connectivity in
place of a physical remote display. This includes the SmartShunt, MPPT SmartSolar Controllers, and
the Cerbo GX. Your MultiPlus Inverter does not have Bluetooth capabilities. The SmartShunt is
monitoring your battery state and tracking how much power is flowing to or from the battery bank,
giving you valuable information regarding your State-of-Charge (SOC).
The MPPT SmartSolar Controller is regulating the power produced by the solar panels to charge the
batteries. Both of these devices have stand-alone Bluetooth connectivity and can be viewed individ-
ually by using the VictronConnect App on a smart phone or tablet. These devices also report to the
Cerbo GX, which acts as a connectivity and monitoring hub for your system. This section contains
details for each of these devices.

Opening the VictronConnect app will cause it to look
for ANY Victron items with a Bluetooth signal within
range. Specific items can be identified by the Icon, as
well as the device “nick-name”. The default nickname
is the device serial number. Serial numbers
for your devices, as well as information needed to
connect to your Cerbo GX are found on the sticker
located on the cover of your component plate, as
well as on the side of your battery.
The first time you connect to any device, you will have to enter the default password (000000). You
can change the password when prompted if you choose, or you can also change the password in
settings at a later time.
If you have lost or forgotten your password, they can be reset through the app, but
this does require a PUK number (a special code) that is on the serial number
sticker of the device. This number is required to ensure that you have
physical possession of the device before clearing a password.
Each of your Bluetooth devices will have three tabs across the
top: Status, History, and Trends.

 This section of VictronConnect enables data-logging, but only while the app is connected and
communicating with the SmartShunt. It will simultaneously log two of the following parameters:
Voltage, Current, Power consumed Ah, or State of Charge.
Once connected, you can change the device nick name, and change or add a password. To do this,
click the settings ( ) in the top right corner. Once in main settings menu, select the menu ( ) in the top
right corner, and choose “Product Info”. This is where you can change the name of the device, check
for updated firmware, and change the password to log onto the device.

This system is utilizing the SmartSolar MPPT 100|50
Solar Controller. A Solar Controller charges a lower
nominal-voltage battery from a higher nominal
voltage PV array. The Solar Controller will charge the
battery with a current up to its rated output. The
SmartSolar MPPT 100|50 Solar Controller has a
maximum of 50 amps output. Selecting the SmartSolar Controller in
VictronConnect will open the main screen.

The SmartShunt is a very valuable piece of equipment in your system. This
is the component that is responsible for helping you keep track of just how
much energy is left in your battery bank at any given time. This component
simply measures battery voltage and current. With those measurements,
and the info provided to it through the settings menu, SOC (State-of-Charge),
and Time Remaining are calculated.

The Battery Guardian Auto installed in your system acts as a smart battery disconnect switch.
The DC loads inside of your coach are running through this component. When the switch is
turned on, the BGA is monitoring the battery voltage. If your battery bank voltage reaches
11.5 VDC for 2 minutes, the BGA will turn off, disconnecting all interior loads from DC power.
When the BGA senses the battery is being charged, it will automatically turn back on. You can manually
disconnect the DC loads inside of the coach by turning off the BGA switch.
Auto-Disconnect Voltage: < 11.5VDC for 2 min.
Auto-Reconnect Voltage:
When BGA senses battery is being charged.

Your batteries are equipped with built in battery heaters to ensure
cold climate does not stop your batteries from charging. The heaters
are enabled or disabled by a lighted switch inside of the coach or on the
iN-Command Display Commander’s Battery Heat Trigger. When
the switch is turned on, the heaters will automatically activate when the
internal temperature of the battery drops below approximately 35°F
(1.6°C) and will automatically shut off when the internal temperature
exceeds approximately 45°F (7.2°C).
The heaters draw 1.8 amps (per battery) of power and typically run on a 30% duty cycle. This means
at 0°F, the heaters will be on 30% of the time, and off 70% of the time. That means if it is cold, we can
expect 0.6 Ah of energy (per battery) to be used to keep the batteries at proper charging temperatures.

If you are using the coach and the temperature is below freezing, you will want to turn on the battery
heat to ensure you are able to take advantage of charging from your solar set up. The heat can either
be turned on just prior to charging, or left on while the coach is in use. Both options have pro’s and
con’s and are based on personal preference and use case.
While leaving the heat on while the coach is in use, you could be using energy to keep the batteries
warm when it is not necessary (remember: it is only really necessary when trying to charge) it also
ensures that if you are charging from solar, the batteries are always able to accept power when it is
available.
Only enabling the heat prior to charging will conserve more battery power, but it can also take an
extended period of time for the batteries to warm up to be able to charge if they are cold soaked. In the
end, the important thing to remember is if the temperature is at or below 35°F, you will need to activate
the battery heat in order to charge the batteries.

NOTE: If the battery has been cold soaked (exposed to below freezing
temperatures for a long period of time without the heater enabled), it
will take 2-4 hours for the internal components of the battery to heat
up enough for the battery to accept a charge.
NOTE: DRAGONFLY DOES NOT RECOMMEND BATTERY HEATER BE ACTIVE WHEN STORING THE BATTERY.

The 600i-L is equipped with a Victron MultiPlus 3kVA Inverter. The MultiPlus
is a powerful true sine wave Inverter and sophisticated battery charger all
in one package. When on shore or generator power, the MultiPlus will pass
power through to the loads from the source. Any available power that is not
used for the loads will be dedicated to battery charging.
The MultiPlus comes from the factory programmed for charging the Lithium
battery bank that is on the system. If the need arises to change the
programming, you MUST reach out to a trained professional.
On the 600i-L, the Inverter is running a specific set of AC circuits. The main
panel provides power to the Inverter when on shore or generator power
and the Inverter passes that power through to a sub-panel. The sub-panel
powers a circuit of general outlets as well as one of the air conditioners. When shore or generator
power is not present, the Inverter will draw power from the battery bank and alter it from DC to AC
power to run the items on the sub-panel.
The Inverter is set up in Unlimited Power Supply (UPS) mode. This means that when the unit is
plugged in to shore or a generator, if the breaker trips or a power outage occurs, the Inverter will
automatically take over and keep the inverted circuits from shutting down.
The Inverter only monitors the loads that are powered through the sub panel. This means, when
plugged in to a smaller shore outlet (or running a portable generator), you can still run more loads
than the power source can supply. If this happens, the breaker will trip and only the inverted loads
on the sub-panel will remain powered. Some suggestions can be found in the Tech Tips section for
using a small shore outlet or portable generator.
The Inverter can be monitored and controlled through the Cerbo using the Remote Console. This is
discussed in more detail in the Remote Console section of this manual starting on pg 12.
The Inverter has a rocker switch on the cover that can limit the functionality to “Charger Only” or
“Off”. When the rocker switch is in the “On” position, the state of the Inverter can be changed
through the Remote Console.
