INSTALLATION and OPERATING INSTRUCTIONS
MPPT HYBRID BOOST CHARGE CONTROLLER

2
Please read these operating instructions carefully before using the appliance.
General information
The MPPT Hybrid BOOST charge controller is a combined wind and solar
controller with integrated micro-controller. The hybrid charge controller was
specially developed for the SHARK Edition and offers the option of connecting
additional solar modules. Heat is dissipated via the well-dimensioned housing
without a fan, which was very important to us.
Thanks to the BOOST function, even low input voltage can be transformed into
the voltage required to charge the battery, making the charging process more
effective!
Night lighting controlled by PV module voltage is also possible.
All operating parameters can be read on an LCD display. All parameters are set
using the button below the LCD display (scan button).
The SHARK wind generator supplies an unregulated three-phase alternating
current. The AC voltage is converted to DC voltage in the charge controller. For
the system voltages 12V, 24V or 48V, the appropriate regulator must be
selected for the generator. Lead-acid, gel, AGM and lithium batteries can be
charged. The appropriate final charging voltage must be set in SETUP. Please
refer to the battery manufacturer's specifications.
The charge controller has been tested.
Hazard warning:
Please note that lead-acid batteries in particular can release dangerous and
explosive gases during charging. If the charge controller is to be installed in
the vicinity of such batteries, ensure good ventilation!
Gel, AGM or lithium batteries are generally maintenance-free and do not emit
gases when charged properly.
The installation must be carried out in a dry, preferably cool place.
All work on electrical systems may only be carried out by qualified persons!

3.2. LCD-Display
There is an LCD display on the top of the hybrid charge controller, which is used to read and set
the operating parameters.
When the SCAN button is pressed, the display is automatically illuminated for 10 seconds.
3.3. SCAN Button
The scan button is located on the top of the charge controller.
How the SCAN button works:
Press briefly to access the DISPLAY menu.
Press for 2 seconds to enter SET MODE (LCD shows "SET"),
here you can change all setting parameters. By pressing again
again for 2 seconds, you return to the DISPLAY menu
again.
By briefly pressing the SCAN button while in the display menu, all
display screens can be scrolled through one after the other. The
parameters can be changed by pressing the SCAN button in SET
MODE.
When SET mode is called up for the first time, the parameters are
changed in 0.1 increments; if you exit SET mode and reactivate it
without changing the display, the values change in 1.0 increments.
Press and hold the SCAN button for 5 seconds to activate the brake manually. BRAKE lights up
in the display.
If you press the SCAN button for 8 seconds, the system voltage (12, 24 or 48V battery system) for
which the controller is designed is briefly displayed. Immediately afterwards, the controller is
reset to the factory settings.
You can reset the parameters to the factory settings by pressing and holding the SCAN button for
10 seconds.

4. Cable dimensioning
As shown in the connection diagram in section 1, a 3-core cable of suitable cross-section must be
laid from the SHARK Edition generator to the charge controller. DC charging current flows from
the charge controller to the batteries via 2 cables. The cross-section of the 2-pole battery cable
should be slightly larger. We recommend here a minimum cross-section of 10mm2. Please
remember to install a fuse (60A) near the battery.
Please refer to the following tables for the recommended cable cross-section:

We recommend the use of tinned silicone cable. With this cable, there is no oxidation of the
individual copper wires.
5. Installing and connecting the charge controller
The charge controller should be installed as close as possible to the battery in a ventilated and
cool room so that it is possible to read the LCD display and operate the manual brake switch. The
charge controller must be mounted vertically for effective cooling. (connections at the bottom).
The charge controller must never be installed in direct sunlight.
Safety note:
As wet batteries in particular (open lead-acid batteries) can emit gases during operation, the
charge controller must not be installed in the vicinity of the batteries. If the charging voltage is
too high, there is a risk of explosion due to sparking in such areas!
Please observe the relevant safety instructions from the battery manufacturer during installation. If
maintenance-free batteries are used, the charge controller can be installed directly next to the
batteries.
A sketch of the connection diagram can be found in section 1 of these operating instructions.
Secure the connection cables so that they cannot come loose.
Please tighten the screws sufficiently!
We recommend using wire end ferrules to attach your cables directly to the charge controller.
Once the wire end ferrules have been securely connected (crimped) to the insulated cables, they
can be connected to the screw terminals.
When connecting the charge controller, it is important that the battery is first connected to
the charge controller with the correct polarity!
The "+" battery cable should be connected via a 60 amp fuse or larger, which should be mounted
as close as possible to the battery (circuit breaker).
Caution!
Please observe the polarity of the battery connection. Mixing up plus and minus can result in the
charge controller being destroyed! This will invalidate the warranty.

9
After connecting the battery, the wind generator and, if necessary, a solar system can be
connected. Furthermore, two separate loads with max. 10A each can be connected to the load
output (DC output). If two loads are connected, they have a common + pole.
If there is sufficient wind when the SHARK Edition is connected, it will immediately build up
voltage at the 3 cable ends if the charge controller is not connected. We therefore recommend
manually blocking the wind generator (before it is connected to the controller!) (e.g. tying a rotor
blade with a line). The three AC cables coming from the wind generator are connected to the
lower side of the charge controller (see section 3.1).
The sequence / polarity is irrelevant for three-phase alternating current.
If you also want to connect a solar module to the hybrid charge controller, this is possible via the
"solar input" connection terminals. The solar power must not exceed the maximum value of
300Wp (exception charge controller WWS06-12-12 here only 150Wp!).
Please pay attention to the correct polarity when connecting.
Possible connection diagrams can be found in section 7.
6. Temperature sensor and external stop switch
The temperature sensor for the battery and the two cables (gray and white) for the external stop
switch are located on the supplied wiring harness with plug-in screw connection (see page 6
photo). Function of the external stop switch: Closed brake ON, (red control LED "Dump" lights
up), open brake OFF
Attention!
NEVER connect the enclosed wiring harness to a live part. This would immediately destroy the
charge controller. During installation, also ensure that free cable ends cannot come into contact
with live parts! This would destroy the controller and void the warranty!
If required, the temperature sensor cable can be extended by the user up to a maximum of 250 cm.
The gray and white cables for the external stop switch can be extended by the user up to a
maximum of 1000 cm.
7. Connecting solar modules
The Boost charge controller is an MPPT wind / solar hybrid charge controller.
You can see some possible connection diagrams in the following illustrations.
It is essential to observe the maximum permissible connected loads
(p. 5, Technical data), Wp, A, open-circuit voltage V.

System voltage 12V:
System voltage 24V:
8. Adjusting the charge controller
Before commissioning, the charge controller must be set to the permissible end-of-charge
voltage according to the battery manufacturer and, if necessary, to your personal application (see
section 9, Setting instructions). The basic settings are preset at the factory for the respective
system voltage.
Factory default setting e.g. for a 12V system:
End of charge voltage 14,4V
Max. Current 32A
Start of charging for boost system 3V
Braking time 10Min.
You must at least change the end-of-charge voltage according to the battery manufacturer's
specifications in the menu item "End Of Charge Voltage" in section 9.3.
Once the set end-of-charge voltage has been reached, the wind generator is braked by the
controller for at least 10 minutes.
The wind generator is then released again and braked again if necessary.

11
Note
If the batteries are too small (less than 100Ah), but also in the case of aged batteries with a loss of
capacity, it can happen that the end-of-charge voltage is reached very quickly. The wind generator
is then slowed down even though the battery has not yet been fully charged. This can be remedied
by connecting a switched-on consumer to the battery during charging. This reduces the voltage
and prevents braking.

10. Troubleshooting
The SHARK only turns slowly
–The manual brake on the charge controller is set to "BRAKE". - A short circuit may have
occurred between the wires when connecting the AC cables in the mast.
–Automatic brake is activated because the parameter settings have been exceeded.
–There is too little wind.
To find the fault, please proceed as follows: Disconnect the three wires to the wind generator on
the charge controller. If the SHARK now starts up (CAUTION: voltage builds up on the cables),
then the fault is between the charge controller and the battery. If the SHARK is still turning
slowly, the fault is between the charge controller and the wind generator. Pay attention to the
recommended cable cross-section and the recommended minimum capacity of the battery to be
charged.

16
The SHARK delivers too little power
The wind speed is too low (see SHARK performance diagram)
Note: The wind speed measured at the top of the mast is lower at the mounting height of the
wind generator!
Turbulence caused by obstacles in the direction of the wind or location for stationary use is
not well chosen, mast may be too short.
The cable cross-section does not match the installed cable length. This results in heat loss in
the cable.
The screw terminals are not tightened.
The existing battery capacity is too low, so that the end-of-charge voltage is reached too
quickly (the battery should have at least 100 Ah).
The existing battery is too old or has lost capacity due to deep discharge, so that the final
charging voltage is reached too quickly.
