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
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.

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 3.8 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.
When the battery voltage drops below float voltage during at least 1 minute a
new charge cycle will be triggered.
Equalization
See section 3.10

● 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.
● In addition to this manual, the system operation or service
manual must include a battery maintenance manual applicable to
the type of batteries used.
Danger of explosion from sparking
Danger of electric shock

5
EN NL FR DE ES SE Appendix
● 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

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 installing the Smart Battery Sense option 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.

7
EN NL FR DE ES SE Appendix
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).
3.5 Remote on-off
The left terminal is connected to the internal 3,3V supply, with a resistor in
series for short circuit protection.
The right terminal (marked as + or marked as H) will switch the controller
on if >3V is applied, and will switch the controller off if <2V is applied or if
the terminal is left free floating.
The recommended use of the remote on-off is:
a. A switch wired between the left and right terminal
b. A switch wired between battery plus and the right terminal.
c) A switch between the right terminal and the charge disconnect terminal of a VE.Bus

3.8 Battery charging information
The charge controller starts a new charge cycle every morning, when the
sun starts shining.
Default setting:
The maximum duration of the absorption period is determined by the battery
voltage measured just before the solar charger starts up in the morning:
Battery voltage Vb (@start-up)
Maximum absorption time
Vb < 23,8V
6h
23,8V < Vb < 24,4V
4h
24,4V < Vb < 25,2V
2h
Vb > 25,2V
1h
(divide voltages by 2 for a 12V system and multiply by two in case of a 48V
system)
If the absorption period is interrupted due to a cloud or due to a power
hungry load, the absorption process will resume when absorption voltage is
reached again later on the day, until the absorption period has been
completed.
The absorption period also ends when the output current of the solar charger
drops to less than 2Amps, not because of low solar array output but because
the battery is fully charged (tail current cut off).
This algorithm prevents over charge of the battery due to daily absorption
charging when the system operates without load or with a small load.
User defined algorithm:
Any setting change performed with the pluggable LCD display or via
Bluetooth will override the rotary switch setting. Turning the rotary switch will
override prior settings made with the pluggable LCD display or via Bluetooth.
3.9 Automatic equalization
Automatic equalization is default set to ‘OFF’. With the VictronConnect app
or the pluggable LCD display this setting can be configured with a number
between 1 (every day) and 250 (once every 250 days). When automatic
equalization is active, the absorption charge will be followed by a voltage
limited constant current period (see table in section 3.5). The current is
limited to 8% of the bulk current for all VRLA (Gel or AGM) batteries and
some flooded batteries, and to 25% of the bulk current for all tubular plate
batteries and the user defined battery type. The bulk current is the rated
charger current unless a lower maximum current setting has been chosen.
In case of all VRLA batteries and some flooded batteries (algorithm number
0, 1, 2 or 3) automatic equalization ends when the voltage limit maxV has
been reached, or after t = (absorption time)/8, whichever comes first.
For all tubular plate batteries and the user defined battery type automatic
equalization ends after t = (absorption time)/2.
When automatic equalisation is not completely finished within one day, it will
not resume the next day, the next equalisation session will take place as
determined by the day interval.

Notes:
1) The factory defined battery type can be selected with the rotary switch next to VE.Direct
connector. The selected type will be shown here. The setting can alter between a factory
defined type and "USER".
2) These values can ONLY be changed for the battery type "USER". The values in the table
are for a 24V-battery.
3) Automatic equalisation can be set to “OFF” (default) or a number between 1 (every day)
and 250 (once every 250 days). See section 3.8 for more details about automatic
equalisation.
4) To allow the charger to equalise the battery properly, use the manual equalise option only
during absorbtion and float periods, and when there is sufficient sunlight. Press SELECT:
the text “” will blink, press SELECT again to start equalisation. To terminate the
equalisation mode prematurely, enter the setup menu and navigate to setup item 10, press
SELECT: the text “” will blink, press SELECT again to stop equalisation. The manual
equalise duration is 1 hour.
5) Relay function (setting 11):

10
Load control (relay switches according to load control mode, see setting 35 and
note 7)
6) The parameter BMS present will be set to 'Y'es internally when a compatible BMS is
detected. Setting 31 can be used to revert the charger to normal operation (i.e. without
BMS) by setting it manually to 'N'o. (for example if the charger is moved to another location
were a BMS is not needed).
Warning: do not set this parameter to 'Y'es when using a VE.Bus BMS connected to
the remote on-off port (see sect 3.5).
7) Load control mode (setting 35).
To use the relay (setting 11, value 10), or the VE.Direct port (setting 58, value 4) to control a
load according the options below:
Value
Description
0
Load output always off
1
Batterylife algorithm (default)
2
Conventional algorithm 1 (off<22.2V, on>26.2V)
3
Conventional algorithm 2 (off<23.6V, on>28.0V)

The RX pin can de-energize the relay (relay off), if relay function 10 of setting 11 has
been set (see note 5, value 10). The load control options (setting 35) remain valid.
In other words, a AND function is created: both the load control and the RX pin must
be high (value=2) or low (value=3) to energize the relay.
10) VE.Direct port TX pin mode (setting 58)
Value
Description
0
Normal VE.Direct communication (default)
For example to communicate with a Color Control panel (VE.Direct cable needed)
1

(ASS0305505500)
3
Light dimming control (pwm inverted) TX digital output cable needed
(ASS0305505500)
4
Load control mode: theTX pin switches according to load control mode, see note 7.
TX digital output cable (ASS0305505500) needed to interface to a logic level load
control port.
11) Press SELECT: the text “” will blink, press SELECT again to reset to original
factory settings. The charger will re-boot. The history data will not be affected (kWh
counter, etc).
12) Press SELECT: the text “” will blink, press SELECT again to erase the history
data (kWh-counter, etc). Note that this takes a few seconds to complete.
Note: any setting change performed with the pluggable LCD display or via
Bluetooth will override the rotary switch setting. Turning the rotary switch will
override prior settings made with the pluggable LCD display or via Bluetooth.
Warning:Some battery manufacturers do recommend a constant current
equalization period, and others do not. Do not use constant current equalization
unless recommend by the battery supplier.

Using the pluggable LCD display or VictronConnect and the procedures
below, most errors can be quickly identified. If an error cannot be resolved,
please refer to your Victron Energy supplier.
Error nr.
Problem
Cause / Solution
n. a.
The LCD does not light up
(no backlight, no display)
The internal power supply used for powering
the converter and the backlight is derived from
either the solar-array or the battery.
If PV and battery voltage are both below 6V
the LCD will not light up. Make sure that the
LCD display is properly inserted into the
socket.
n. a.
The LCD does not light up
(backlight works, no display,
charger seems to work)
This may be due to low ambient temperature.
If the ambient temperature is below -100C
(140F) the LCD-segments can become vague.
Below -200C (-40F) the LCD-segments can
become invisible.
During charging the LCD-display will warm up,
and the screen will become visible.
n. a.
The charge controller does
not charge the battery
The LCD-display indicates that the charge-
current is 0 Amps.
Check the polarity of the solar-panels.
Check the battery breaker
Check if there is an error indication on the LCD
Check if the charger is set to "ON" in the
menu.
Check if the Remote input is connected.
Check if the right system voltage has been
selected
n. a.
High temperature: the
thermometer icon blinks
This error will auto-reset after temperature has
dropped.
Reduced output current due to high
temperature.
Check the ambient temperature and check for
obstructions near the heatsink.
Err 2
Battery voltage too high
(>76,8V)
This error will auto-reset after the battery
voltage has dropped.
This error can be due to other charging
equipment connected to the battery or a fault
in the charge controller.
Err 17
Controller overheated
despite reduced output
current
This error will auto-reset after charger has
cooled down.
Check the ambient temperature and check for
obstructions near the heatsink.
Err 18
Controller over-current
This error will auto-reset.
Disconnect the charge controller from all
power-sources, wait 3 minutes, and power up
again.
If the error persists the charge controller is
probably faulty.
Err 20
Maximum Bulk-time
exceeded
This error can only occur when the maximun
bulk-time protection is active. This error will not
auto-reset.
This error is generated when the battery-
absorption-voltage is not reached after 10
hours of charging.
For normal solar installations it is advised not
to use the maximum bulk-time protection.
Err 21
Current sensor issue
The charge controller is probably faulty.
This error will not auto-reset.
Err 26
Terminal overheated
Power terminals overheated, check wiring and

fasten bolts if possible.
This error will auto-reset.
Err 33
PV over-voltage
This error will auto-reset after PV-voltage has
dropped to safe limit.
This error is an indication that the PV-array
configuration with regard to open-circuit
voltage is critical for this charger. Check
configuration, and if required, re-organise
panels.
Err 34
PV over-current
The current from the solar-panel array has
exceeded 75A. This error could be generated
due to an internal system fault.
Disconnect the charger from all power-
sources, wait 3 minutes, and power-up again.
If the error persists the controller is probably
faulty.
This error will auto-reset.
Err 38
Input shutdown due to
battery over-voltage
To protect the battery from over-charging the
panel input is shut down. To recover from this
condition first disconnect the solar panels and
disconnect the battery. Wait for 3 minutes
reconnect the battery first and next the panels.
If the error persists the charge controller is
probably faulty.
Inf 65
Communication warning
Communication with one of the paralleled
controllers was lost. To clear the warning,
switch the controller off and back on.
Inf 66
Incompatible device
The controller is being paralleled to another
controller that has different settings and/or a
different charge algorithm.
Make sure all settings are the same and
update firmware on all chargers to the latest
version.
Err 67
BMS connection lost
Connection to the BMS lost, check the
connection (Cabling / Bluetooth link). When
the charger needs to operate in stand-alone
mode again, change to setup menu setting
‘BMS’ from ‘Y’ to ‘N’ (setup item 31).
Err 114
CPU temperature too high
This error will reset after the CPU has cooled
down.
If the error persists, check the ambient
temperature and check for obstructions near
the air inlet and outlet holes of the charger
cabinet.
Check manual for mounting instructions with
regard to cooling. If error persists the controller
is probably faulty.
Err 116
Calibration data lost
This error will not auto-reset.
Err 119
Settings data lost
This error will not auto-reset.
Restore defaults in the setup menu (setup item
62).
Disconnect the charge controller from all
power-sources, wait 3 minutes, and power up
again.
