Solbian Allin1 User manual

Solbian Allin1 User’s Manual
The purpose of this document is to give installation information specific to the Allin1 series. Much of the
information in the General Solbian User’s Manual still applies, so please see that document for more
information. Prior to installation, refer to the General Solbian User’s Manual for all safety information.
THE FOLLOWING INSTRUCTIONS ARE EXCLUSIVELY GENERAL ADVICE. WE RECOMMEND THAT YOU HAVE
THE MODULES INSTALLED BY QUALIFIED TECHNICIANS, RESPECTING STANDARDS IEC 62548, 62257 AND
APPLICABLE ABYC RECOMMENDATIONS. PLEASE CONTACT US DIRECTLY FOR TECHNICAL ASSISTANCE.
ELECTRICAL INSTALLATION
The PV modules of the ALLinONE series include an on-board high-efficiency MPPT charge controller. Thanks
to this advanced controller, the panels can directly charge lead (Pb) and lithium (Li) batteries with 12V
(standard) or 24V (special ordered) nominal voltage.
WARNING: THE CHARGE CONTROLLER IS ONLY PROTECTED AGAINST ACCIDENTAL REVERSE POLARITY
CONNECTION IF THE FUSE (INCLUDED IN THE PACKAGE) IS INSTALLED.
ALLinONE modules are supplied with a flexible cable resistant to weathering that can be directly connected
to the positive and negative poles of your battery and to the supplied holder for the external fuse. The
electronics are configured at the factory so be sure to order the model suited to your battery type. Take
care to maintain the proper polarity when installing the panels (See below).
The length and section of supplied cable are defined as to prevent too large voltage drop between charge
controller and battery. If extension is needed it must be realized with 4 mm2(12AWG) copper section
cables. In any case a total cable length larger than 8 meters is not advised. Each ALLinONE, thanks to the
integrated electronics, behaves like an independent charger, thus more ALLinONE panels can be used to
charge the same battery by simply connecting them in parallel on the battery leads.
CABLE TERMINATIONS
Negative (blue from panel):
There usually should be general neg. bus bar or post that the battery neg. connects to, and the solar neg.
needs to connect to that also. And of course the solar neg. needs to be on the load side of any monitor or
ammeter shunt (the side of the shunt away from the battery).
Positive (brown from panel):
Here also there is usually a positive post or bus bar where the positive lead from the battery is connected.
Sometimes this is simply the battery side of the main battery switch, and often the engine alternator
positive (red) cable is connected there as well. Going direct to the battery positive post is certainly
possible, but in any case the goal is to avoid too many connections piled on each other in any one spot.
Terminals:
We highly suggest using properly crimped wire terminals with heat shrink over the crimp, and with the
proper sized ring terminal or plug for wherever it is connected.
POSSIBLE FAILURE MODES
Fractured cells: Fracturing can be caused by excessive bending of the module during installation or use, or
by impact or mechanical stress. Fractured photovoltaic cells do not normally cause a total loss of
performance in a module, but more usually a drop in efficiency.
Defects with the charge regulator: Charge regulators, like all electronic devices, can fail.
ALLinONE modules need to be connected to a battery to properly operate. Measuring voltage and current
output from the disconnected leads can be misleading. To measure the values of current, voltage and
power, we advise to use a suitable measurement device, like the Wattmeter supplied by Solbian.

Note: measuring the output voltage from the leads, without any load connected and under sun light, can
give some hints about product status. If voltage measured is not close to 14 V and 28 V (for 12 and 24 Volt
lead batteries charger) that means the system can be defective.
In any case, first of all, check the state of the electrical connections between the modules and batteries
with particular focus on polarity (brown cable means positive while blue means negative).
PROTECTIVE FILM ON FRONT OF MODULE
The modules are shipped with a protective film on the front surface. We recommend that you remove this
after the installation has been completed. In any case, the protective film must be removed before using
the module for the first time.
CONTROLLER SPECIFICATION
Solbian Charger is a DC-DC boost converter designed to maximize the power generated by photovoltaic panels for any
external condition of temperature and solar radiation intensity. Optimization of power conversion is obtained with
embedded logic performing a Maximum Power Point Tracking (MPPT) algorithm on the PV module connected to the
converter. To maximize the efficiency and reduce the size, Solbian Charger uses Power MOSFETs for active switching
and synchronous rectification, minimizing the number of external devices.
The controller, being a high efficiency, monolithic, boost converter with 4-phase interleaved topology implementing
MPPT avoids the use of electrolytic capacitors which can severely limit the system lifetime.
The controller operates at fixed frequency in PWM mode, where the duty cycle is controlled by embedded logic
running a "Perturb & Observe" MPPT algorithm. The embedded charge controller prevents battery overvoltage and
overcurrent. The controller implements a fast and efficient CC-CV (constant current-constant voltage) IC architecture
and logic that is the result of Solbian’s experience of hundreds of design and installations of PV in boats. The set up of
the system takes into account the natural “off” cycles during the nights.
Safety of the application is guaranteed by automatic halt of the driver in case of output overvoltage or over-
temperature.
