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 mm
2
(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.
