1. General Description
1.1 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.
1.2 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.
1.3 Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%. Full output
current up to 40°C (104°F).
1.4 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.
1.5 Internal temperature sensor
Compensates absorption and float charge voltages for
temperature.
1.6 Automatic battery voltage recognition
The controllers will automatically adjust to a 12V, 24V or a 48V
system. A computer or a Color Control panel is required to set the
controller to 36V.
1.7 Flexible charge algorithm
Eight preprogrammed algorithms, selectable with a rotary switch.

1.8 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.
1.8.1. Bulk stage
During this stage the controller delivers as much charge current
as possible to rapidly recharge the batteries.
1.8.2. Absorption stage
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.
1.8.3. Float stage
During this stage, float voltage is applied to the battery to
maintain it in a fully charged state.
1.8.4. Equalization
See section 3.7.1
1.9 Connectivity
See section 3.8 of this manual.
1.10 Remote on-off
VE.Direct non inverting remote on-off cable (ASS030550300)
needed. An input HIGH (Vi > 8V) will switch the controller on, and
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.
1.11 Real-time data display on Apple and Android
smartphones, tablets and other devices
VE.Direct Bluetooth Smart dongle
and VictronConnect app
needed: see section 3.8.

2. Safety instructions
● Please read this manual carefully before the product is
installed and put into use.
● This product is designed and tested in accordance with
international standards. The equipment should be used for the
designated application only.
● Install the product in a heatproof environment. Ensure
therefore that there are no chemicals, plastic parts, curtains or
other textiles, etc. in the immediate vicinity of the equipment.
● 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.
● 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).
Danger of explosion from sparking
Danger of electric shock

4
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.
3. Installation
3.1 General
● Mount vertically on a non-flammable surface, with the power
terminals facing downwards.
● Mount close to the battery, but never directly above the battery
(in order to prevent damage due to gassing of the battery).
● Grounding: the heatsink of the controller should be connected
to the grounding point.
● Use one grounding point only (preferably close to the battery,
for safety reasons) to which the battery negative or battery
positive should be connected. Do not also connect the the solar
array negative to ground. This would result in unwanted ground
currents
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.

3.2 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.
The controllers can be used with any PV configuration that
satisfies the three above mentioned conditions.
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
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.
3.3 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).
3.4 More about automatic battery voltage recognition
The system voltage is stored in non volatile memory.
In case of a 24V or 48V battery, a reset (to 12V) occurs only
when the output voltage decreases to less than 2V and the
voltage on the PV input exceeds 7V. This may occur when the
battery has been disconnected before PV voltage starts to rise in
the early morning. When the (24V or 48V) battery is reconnected
later during the day, the system voltage is restored to 24V resp.

6
48V after 10 seconds if the battery voltage exceeds 17,5V resp.
35V.
Automatic voltage recognition can be switched off and a fixed
12/24/36 or 48V system voltage can be set with the
VictronConnect app (see sect 3.8): recommended if the battery is
frequently disconnected from the controller.
The controller can be reset by short circuiting the output and
applying a voltage exceeding 7V on the input (for example with a
small power supply, or a solar panel) during a few seconds. After
a reset, the controller will automatically adjust itself to a 12V
system, a 24V system (when connecting a 24V battery with at
least 17,5V) or a 48V system (when connecting a 48V battery
with at least 35V).
The VictronConnect app (see sect. 3.8) is required to set the
MPPT to 36V.
