1. General Description
Bluetooth Smart built-in: dongle not needed
The wireless solution to set-up, monitor and update the controller using
Apple and Android smartphones, tablets or other devices.
VE.Direct port and two VE.Can ports
Both ports can be used for a wired data connection to a Color Control,
Venus GX, PC or other devices.
Remote on-off input
On/off control by a VE.Bus BMS when charging Li-ion batteries.
Programmable relay
Can be programmed (a.o. with a smartphone) to trip on an alarm, or other
events.
Optional: pluggable LCD display
Simply remove the rubber seal that protects the plug on the front of the
controller and plug-in the display.
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.
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 SmartSolar algorithm will always maximize energy harvest by
locking to the optimum MPP.
Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%. Full output current up to
40°C (104°F).
Extensive electronic protection
Over-temperature protection and power derating when temperature is high.
PV reverse polarity protection.
Internal temperature sensor
Compensates absorption and float charge voltages for temperature.
(range 6°C to 40°C)

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
Alternatively, Bluetooth communication can be set up between a BMV-712
battery monitor with battery temperature sensor and the solar charge
controller
For more detail please enter smart networking in the search box on
our website.
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 or the optionel LCD
display. Similarly, manual setting is required in case of 36V system.
Flexible charge algorithm
Fully programmable charge algorithm, and eight preprogrammed algorithms,
selectable with a rotary switch.
Adaptive three step charging
The SmartSolar MPPT Charge Controller is configured for a three step
charging process: Bulk –Absorption –Float.
A regular equalization charge can also be programmed: see section 3.12 of
this manual.
Bulk
During this stage the controller delivers as much charge current as possible
to rapidly recharge the batteries.
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.
Float
During this stage, float voltage is applied to the battery to maintain it in a fully
charged state.
Equalization

● 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.
● Maximum current through a MC4 terminal: 30A
● The grounding terminal is located in the wiring compartment
and is identified by the symbol below:

3. Installation
WARNING: DC (PV) 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 be
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 may be needed to parallel the strings of
solar panels. (Maximum current through a MC4 terminal: 30A)
3.2 Grounding
● Battery grounding: the charger can be installed in a positive or negative
grounded system.
Note: apply a single ground connection (preferably close to the battery) 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). These 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 charger must not be connected with grounded PV arrays. (one ground
connection only)
● 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)
● 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 or 250V, depending on model.
For example:
24V battery, mono- or polycristalline panels, max PV voltage 150V:
● Minimum number of cells in series: 72 (2x 12V panel in series
or one 24V panel).
● Recommended number of cells for highest controller 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, mono- or polycristalline panels, max PV voltage 250V:
● Minimum number of cells in series: 144
(4x 12V panel or 2x 24V panel in series).
● Maximum: 360 cells (10x 12V or 5x 24 panel in series).
Remark: at low temperature the open circuit voltage of a 216 cell solar array
may exceed 150V, and the open cicuit voltage of a 360 cell array may
exceed 250V, 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: if required, connect the remote on-off, and programmable relay
Third: connect the solar array (when connected with reverse polarity, the
controller will heat up but will not charge the battery).
Torque: 2.4 Nm
3.5 Remote on-off
Use modes of the system on-off:
a. ON when the L and H terminal are interconnected (switch or relay contact)
b. ON when the L terminal is pulled to battery minus (V< 3.5V)
c. ON when the H terminal is high (2.9V < VH < Vbat)
d. OFF in all other conditions
The recommended use of the remote on-off is:
a. A switch wired between the L-H pins
b. A switch wired between battery plus and the H-pin.
c) A switch between the L-pin and the charge disconnect terminal of a VE.Bus BMS

3.6 CAN bus interface
The charger is equipped with two CAN bus RJ45 sockets.
The CAN bus on this charger is not galvanically isolated. The CAN bus is
referenced to the minus battery connection.
The CAN bus interface will be referenced to ground if the minus pole of the
battery is grounded. In case of a positive grounded system, a CAN isolation
module will be needed to reference the CAN bus interface to ground.
The end of a CAN cable should have a bus terminator. This is achieved by
inserting a bus terminator in one of the two RJ45 connectors and the CAN
cable in the other. In case of a node (two CAN cables, one in each RJ45
connector), no termination is needed.
Supply voltage (V+ supply): 9V-70V
Maximum supply current: 500mA
Data rate: 250 kbps
CANH/CANL voltage tolerance: +/-70VDC
CAN transceiver ISO specification: ISO 11898-2:2016
To provide maximum flexibility, the battery voltage is used for the V+
supply line of VE.CAN. This means that all equipment connected to
VE.CAN are a permanent load to the battery.
