1. General Description
1.1 PV voltage up to 100V
The charge controller is able to charge a lower nominal-voltage
battery from a higher nominal voltage PV array.
The controller will automatically adjust to a 12 or 24V nominal
battery voltage.
1.2 Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in case of a clouded sky, when light intensity is
changing continuously, an ultra fast MPPT controller will improve
energy harvest by up to 30% compared to PWM charge
controllers and by up to 10% compared to slower MPPT
controllers.
1.3 Advanced Maximum Power Point Detection in case of
partial shading conditions
If partial shading occurs, two or more maximum power points may
be present on the power-voltage curve.
Conventional MPPTs tend to lock to a local MPP, which may not
be the optimum MPP.
The innovative BlueSolar algorithm will always maximize energy
harvest by locking to the optimum MPP.
1.4 Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%. Full output
current up to 40°C (104°F).
1.5 Extensive electronic protection
Over-temperature protection and power derating when
temperature is high.
PV short circuit and PV reverse polarity protection.
PV reverse current protection.
1.6 Internal temperature sensor
Compensates absorption and float charge voltages for
temperature. (range 6°C to 40°C)
1.7 Optional external voltage and temperature sensor
(range -20°C to 50°C)
The Smart Battery Sense is a wireless battery voltage-and-
temperature sensor for Victron MPPT Solar Chargers. The Solar
Charger uses these measurements to optimize its charge
parameters. The accuracy of the data it transmits will improve
battery charging efficiency, and prolong battery life (VE.Direct
Bluetooth Smart dongle needed).

Alternatively, Bluetooth communication can be set up between a
BMV-712 battery monitor with battery temperature sensor and the
solar charge controller
(VE.Direct Bluetooth Smart dongle needed). For more detail
please enter smart networking in the search box on our website.
1.8 Automatic battery voltage recognition
The controllers will automatically adjust to a 12V, 24V or a 48V
system one time only. If a different system voltage is required at
a later stage, it must be changed manually, for example with the
Bluetooth app, see section 1.10.
1.9 Flexible charge algorithm
Fully programmable charge algorithm, and eight preprogrammed
algorithms, selectable with a rotary switch.
1.10 Adaptive three step charging
The BlueSolar MPPT Charge Controller is configured for a three
step charging process: Bulk – Absorption – Float.
A regular equalization charge can also be programmed: see
section 3.8 of this manual.
1.10.1. Bulk
During this stage the controller delivers as much charge current
as possible to rapidly recharge the batteries.
1.10.2. Absorption
When the battery voltage reaches the absorption voltage setting,
the controller switches to constant voltage mode.
When only shallow discharges occur the absorption time is kept
short in order to prevent overcharging of the battery. After a deep
discharge the absorption time is automatically increased to make
sure that the battery is completely recharged. Additionally, the
absorption period is also ended when the charge current
decreases to less than 2A.
1.10.3. Float
During this stage, float voltage is applied to the battery to
maintain it in a fully charged state.
1.10.4. Equalization
See section 3.8
1.11 Remote on-off
VE.Direct non inverting remote on-off cable (ASS030550300)
needed. An input HIGH (Vi > 8V) will switch the controller on, and

3
EN NL FR DE ES SE Appendix
an input LOW (V < 2V, or free floating) will switch the controller
off.
Application example: on/off control by a VE.Bus BMS when
charging Li-ion batteries.
1.12 Configuring and monitoring
Configure the solar charge controller with the VictronConnect
app. Available for iOS & Android devices; as well as macOS and
Windows computers. An accessory might be required; enter
victronconnect in the search box on our website and see the
VictronConnect download page for details.
For simple monitoring, use the MPPT Control; a panel mounted
simple yet effective display that shows all operational parameters.
Full system monitoring including logging to our online portal,
VRM, is done using the GX Product range

therefore that there are no chemicals, plastic parts, curtains or
other textiles, etc. in the immediate vicinity of the equipment.
● The product is not allowed to be mounted in a user accessible
area.
● Ensure that the equipment is used under the correct operating
conditions. Never operate it in a wet environment.
● Never use the product at sites where gas or dust explosions
could occur.
● Ensure that there is always sufficient free space around the
product for ventilation.
● Refer to the specifications provided by the manufacturer of the
battery to ensure that the battery is suitable for use with this
product. The battery manufacturer's safety instructions should
always be observed.
●Protect the solar modules from incident light during
installation, e.g. cover them.
● Never touch uninsulated cable ends.
● Use only insulated tools.
● Connections must always be made in the sequence described
in section 3.5.
● The installer of the product must provide a means for cable
strain relief to prevent the transmission of stress to the
connections.
Danger of explosion from sparking
Danger of electric shock

EN NL FR DE ES SE Appendix
● In addition to this manual, the system operation or service
manual must include a battery maintance manual applicable to
the type of batteries used.
● Use flexible multistranded copper cable for the battery and PV
connections.
The maximum diameter of the individual strands is
0,4mm/0,125mm² (0.016 inch/AWG26).
A 25mm² cable, for example, should have at least 196 strands
(class 5 or higher stranding according to VDE 0295, IEC 60228
and BS6360).
An AWG2 gauge cable should have at least 259/26 stranding
(259 strands of AWG26).
Maximum operating temperature: ≥ 90°C.
Example of suitable cable: class 5 “Tri-rated” cable (it has three
approvals: American (UL), Canadian (CSA) and British (BS))
In case of thicker strands the contact area will be too small
and the resulting high contact resistance will cause severe
overheating, eventually resulting in fire.
● The grounding terminal is located in the wiring compartment
and is identified by the symbol below:

3. Installation
WARNING: DC INPUT NOT ISOLATED FROM BATTERY
CIRCUIT
CAUTION: FOR PROPER TEMPERATURE COMPENSATION
THE AMBIENT CONDITION FOR CHARGER AND BATTERY
MUST BE WITHIN 5°C.
3.1 General
● Mount vertically on a non-flammable surface, with the power
terminals facing downwards. Observe a minimum clearance of
10 cm under and above the product for optimal cooling.
● Mount close to the battery, but never directly above the
battery (in order to prevent damage due to gassing of the
battery).
● Improper internal temperature compensation (e.g. ambient
condition battery and charger not within 5°C) can lead to
reduced battery lifetime.
We recommend using a direct battery voltage sense source
(BMV, Smart Battery Sense or GX device shared voltage sense)
if larger temperature differences or extreme ambient
temperature conditions are expected.
● Battery installation must be done in accordance with the
storage battery rules of the Canadian Electrical Code, Part I.
● The battery connections (and for Tr version also PV
connections) must guarded against inadvertent contact
(e.g. install in an enclosure or install the optional WireBox).
Tr models: use flexible multistranded copper cable for the battery
and PV connections: see safety instructions.
MC4 models: several splitter pairs will be needed to parallel the
strings of solar panels. Do not exceed the maximum current
rating of 25A per connector pair

3.2 Grounding
● Battery grounding: the charger can be installed in a positive or
negative grounded system.
Note: apply a single ground connection to prevent
malfunctioning of the system.
● Chassis grounding: A separate earth path for the chassis
ground is permitted because it is isolated from the positive and
negative terminal.
● The USA National Electrical Code (NEC) requires the use of
an external ground fault protection device (GFPD). The
Victron MPPT chargers do not have internal ground fault
protection. The system electrical negative should be bonded
through a GFPD to earth ground at one (and only one)
location.
● The plus and minus of the PV array should not be grounded.
Ground the frame of the PV panels to reduce the impact of
lightning.
WARNING: WHEN A GROUND FAULT IS INDICATED,
BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE
UNGROUNDED AND HAZARDOUS.
3.3 PV configuration (also see the MPPT Excel sheet on our
website)
● Provide a means to disconnect all current-carrying
conductors of a photovoltaic power source from all other
conductors in a building or other structure. A switch, circuit
breaker, or other device, either ac or dc, shall not be installed
in a grounded conductor if operation of that switch, circuit
breaker, or other device leaves the marked, grounded
conductor in an ungrounded and energized state.
● The controllers will operate only if the PV voltage exceeds
battery voltage (Vbat).
● PV voltage must exceed Vbat + 5V for the controller to start.
Thereafter minimum PV voltage is Vbat + 1V.
● Maximum open circuit PV voltage: 150V.
For example:
24V battery and mono- or polycristalline panels
● Minimum number of cells in series: 72 (2x 12V panel in series
or one 24V panel).
● Recommended number of cells for highest controller

8
efficiency: 144 cells (4x 12V panel or 2x 24V panel in series).
● Maximum: 216 cells (6x 12V or 3x 24V panel in series).
48V battery and mono- or polycristalline panels
● Minimum number of cells in series: 144
(4x 12V panel or 2x 24V panel in series).
● Maximum: 216 cells.
Remark: at low temperature the open circuit voltage of a 216 cell
solar array may exceed 150V, depending on local conditions and
cell specifications. In that case the number of cells in series must
be reduced.
3.4 Cable connection sequence (see figure 1)
First: connect the battery.
Second: connect the solar array (when connected with reverse
polarity, the controller will heat up but will not charge the battery).
Torque: 2,4 Nm
