iSTA BREEZE I 1000 Istapower Wind and Solar Charge Controller
Instructions
Introduction
The function of the charge controller is to monitor the battery voltage, and
once it reaches full charge, disconnect energy sources (wind turbine and / or
solar panel), in order to avoid overloading the battery bank. Furthermore, at
risk to the turbine (excessive rotation), the controller actuates the braking
automatically. Also in case of risk to the controller, such as over
temperature, load interruption occurs and braking of the turbine. Other
protections are also present, such as input voltage limits.
The Istapower controller allows direct connection of wind generator (three-
phase turbine with permanent magnets,) and 12/24/48V battery bank, in order to
generate a complete solution to battery charge with power wind. It also have
input for solar cell panel (600W maximum), in order to use solar and wind
energy (hybrid system). The hybrid system as an interesting combination, since
often days of little wind exhibit good insulation, and vice versa.
All the controller circuit is designed with electronic components without the
use of electromechanical components (relays). This contributes to a long
service life and substantially increases the reliability of the installation.
The whole set is packaged in a metal housing of high mechanical strength which
removes the heat generated efficiently, avoiding overheating.
Connection
The controller has the following connections:
The main connector has seven contact: three contacts for the , three phases of
the wind turbine (PHASE A, B, C), a contact to the positive terminal of the
battery (BATTERY+), a contact to the negative terminal of the battery
(BATTERY-), a contact to the ,,, negative terminal of the solar panel
(SOLAR-), and a contact to the positive terminal of the solar panel (SOLAR+).
Internally there is a 40A fuse protect the circuit in the event of a short
circuit. Normally, this fuse should not burn because there is protection
against reverse polarity, both the battery and solar panel.
Two LED lights (yellow and red) indicate the operation of the controller. They
are located to the left of the main connector (front view), as shown in the
drawing.
As the braking is based on dynamic friction, that is, the energy generated by
the turbine itself, will not necessarily completely stopping. A braked wind
turbine could continue to rotate, but with a low speed. In case of strong
winds (above 35 km / h) may occur that the turbine fall your speed when there
is a wind temporary interruption, allowing your downswing. Once at low speed,
the turbine will remain so until manual braking is off, even if the wind
return to levels above 45 km / h.
Operation
The mechanical assembly of the controller must always be vertical, with
connectors for battery connection, wind turbine and solar panel in the lower
position. This ensures efficient cooling by convection.
Connect the battery bank to the controller. The wiring to the battery bank
must have a 6 mm2 of copper in diameter and preferably as short as possible
(less than 3 meters between controller and battery bank). After a moment, the
two LEDs (red and yellow), indicating system startup. Soon after, the yellow
LED should be activated, indicating that the controller measured the voltage
of the battery bank, and initialize its internal constants properly
When connecting pay attention to the polarity battery. If reversed there will
be no damage to the system, but the controller will remain de-energized.
Once energized the controller,. Place the three wind turbine wires shorted
together to force the turbine stop. Beware of terminals open turbine, since
this situation can arise high voltages if the propeller is moving. Wait about
30 seconds to perform complete cycle of braking, then remove the short circuit
between the turbine wires and connect to the corresponding terminals (phase A,
B, C). The order of the wires is irrelevant. Do not do this operation if there
is strong wind, because the little time with open wires may be sufficient to
speed propeller and generate high voltages at its terminals. In this case,
first stop mechanically the propeller spinning before handling the wires of
the wind generator.
Warning: the wires of wind generator open can generate very high voltages if the propeller is moving, with electrical shock hazard. Always should do short circuit the terminals or stop mechanically the turbine before handling it.
If the installation has solar panel connect it to the controller. The system
is connected and ready to operate. Press the manual brake button to release
the brake (red LED should turn off). If the turbine was mechanically
immobilized can be released.
When there is load conditions (rotation in the wind turbine or the solar panel
voltage, in the case of hybrid systems) the yellow LED flashes, indicating
that the battery bank is being charged.
When reach full charge voltage, the red LED is turned on and the charge of the
battery bank is interrupted.
