1 General Description
1.1 Ultra fast MPPT tracking
Especially in case of a clouded sky, when light intensity is changing continuously, a fast
MPPT algorithm 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 VE.Direct
For a wired data connection to a Color Control panel, PC or other devices
1.3 Load output
Deep discharge of the battery can be prevented by connecting all loads to the load
output. The load output will disconnect the load when the battery has been discharged
to a pre-set voltage.
Alternatively, an intelligent battery management algorithm can be chosen: see Battery
Life.
The load output is short circuit proof.
Some loads (especially inverters) can best be connected directly to the battery, and the
inverter remote control connected to the load output. A special interface cable may be
needed, please see section 3.6.
1.4 Battery Life: intelligent battery management
When a solar charge controller is not able to recharge the battery to its full capacity
within one day, the result is often that the battery will continually be cycled between a
‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no
regular full recharge) will destroy a lead-acid battery within weeks or months.
The Battery Life algorithm will monitor the state of charge of the battery and, if needed,
day by day slightly increase the load disconnect level (i.e. disconnect the load earlier)
until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%.
From that point onwards the load disconnect level will be modulated so that a nearly 100%
recharge is achieved about once every week.
1.5 Internal temperature sensor
Compensates absorption and float charge voltages for temperature.
1.6 Automatic battery voltage recognition
The controller will automatically adjust itself to a 12V or a 24V 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 1.8.

1.7 Three step charging
The controller is configured for a three step charging process: Bulk – Absorption - Float.
See section 3.8 and section 5 for default settings.
See section 1.8 for user defined sttings
1.7.1. Bulk
During this stage the controller delivers as much charge current as possible to rapidly
recharge the batteries.
1.7.2. 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 1A.
1.7.3. Float
During this stage, float voltage is applied to the battery to maintain a fully charged state.
When the battery voltage drops below float voltage during at least 1 minute a new charge
cycle will be triggered.
1.7.4. Equalization
See section 3.8
1.8 Configuring and monitoring
- Bluetooth Smart (VE.Direct Bluetooth Smart dongle needed): connect to a smartphone or
tablet running iOS or Android.
- Use the VE.Direct to USB cable (ASS030530000) to connect to a PC, a smartphone with
Android and USB On-The-Go support (requires additional USB OTG cable).
- Use a VE.Direct to VE.Direct cable to connect to a MPPT Control, a Color Control or a
Venus GX.
Several parameters can be customized with the VictronConnect app.

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 substrate, 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 Bluetooth Smart dongle and 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 and PV connections must guarded against inadvertent contact (e.g. install in
an enclosure or install the optional WireBox S).
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 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 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
grounded conductor in an ungrounded state while the system remains energyzed.
● The controller 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.

5
EN NL FR DE ES SE Appendix
● Maximum open circuit PV voltage: 75V respectively 100V
For example:
12V battery and mono- or polycristalline panels connected to a 75V controller
● Minimum number of cells in series: 36 (12V panel).
● Recommended number of cells for highest controller efficiency: 72
(2x 12V panel in series or 1x 24V panel).
● Maximum: 108 cells (3x 12V panel in series).
24V battery and mono- or polycristalline panels connected to a 100V controller
● Minimum number of cells in series: 72
(2x 12V panel in series or 1x 24V panel).
● Maximum: 144 cells (4x 12V panel in series).
Remark: at low temperature the open circuit voltage of a 108 cell array may exceed 75V
and and the open circuit voltage of a 144 cell solar array may exceed 100V, 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 3)
First: connect the cables to the load, but ensure that all loads are switched off.
Second: connect the battery (this will allow the controller to recognize system voltage).
Third: connect the solar array (when connected with reverse polarity, the controller will
heat up but will not charge the the battery).
The system is now ready for use.
3.5 Configuration of the controller
The VE.Direct communication port (see sect. 1.8) can be used to configure the controller.
(dongle needed when using the Bluetooth app)
3.6 The load output (see figure 1 and 2 at the end of the manual)
The VE.Direct communication port (see sect. 1.8) can be used to configure the load output.
(dongle needed when using the Bluetooth app)
Alternatively, a jumper can be used to to configure the load output as follows:
● No jumper: BatteryLife algorithm (see 1.4)
● Jumper between pin 1 and pin 2: conventional
Low voltage load disconnect: 11,1V or 22,2V
Automatic load reconnect: 13,1V or 26,2V
● Jumper between pin 2 and pin 3: conventional
Low voltage load disconnect: 11,8V or 23,6V
Automatic load reconnect: 14V or 28V

Some loads with high inrush current can best be connected directly to the battery. If
equipped with a remote on-off input, these loads can be controlled by connecting the load
output of the controller to this remote on-off input. A special interface cable may be needed.
Alternatively, a BatteryProtect may be used to control the load. Please see our website for
specifications.
Low power inverters, such as the Phoenix VE.Direct inverters up to 375VA, can be
powered directly by the load output, but the maximum output power will be limited by the
current limit of the load output.
Phoenix VE.Direct inverters can also be controlled by connecting the left side connection
of the remote control to the load output.
The bridge on the remote control between left and right must be removed.
The Victron inverters model Phoenix 12/800, 24/800, 12/1200 and 24/1200 can be
controlled by connecting the right side connection of the inverter remote control directly to
the load output (see figure 4 at the end of this manual).
For the Victron inverters model Phoenix 12/180, 24/180, 12/350, 24/350, the Phoenix
Inverter Compact models and the MultiPlus Compact models an interface cable is needed:
the Inverting remote on-off cable, article number ASS030550100, see figure 5 at the end of
this manual.
3.7 LEDs
Green LED: indicates which load output control algorithm has been chosen.
On: one of the two conventional load output control algorithms (see Fig 2)
Blinking: BatteryLife load output control algorithm (see Fig 2)
Yellow LED: signals charge sequence

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)
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 1Amp, 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:
The default settings can be modified with Bluetooth or via VE.Direct.
3.8 Automatic equalization
Automatic equalization is default set to ‘OFF’. With the Victron Connect app (see sect 1.7)
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. The current is limited to 8% of the bulk current for
the factory default battery type, and to 25% of the bulk current for a user defined battery
type. The bulk current is the rated charger current unless a lower maximum current setting
has been chosen.
When using the factory default battery type, automatic equalization ends when the voltage
limit 16.2V / 32.4V has been reached, or after t = (absorption time)/8, whichever comes first.
For 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.
