POSSIBLE FAILURE MODES

P

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.

P

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 suggest the use a suitable measurement device, like 

the Wattmeter supplied by Solbian.

To measure the output voltage from the leads, without any load connected and under sun light, can anyway gives 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 modules and batteries with particular focus on polarity 

(brown cable means positive while blue means negative).

EXCERPT FROM WARRANTY TERMS

SolbianFlex modules are covered by a warranty for manufacturing defects and performance. Here are some of the warranty 

conditions. The text of the full warranty (the sole applicable warranty) is available on request and is published on the website 

www.solbian.eu

TWO YEAR WARRANTY ON PRODUCT INTEGRITY

SolbianFlex serie SP, SX, CP, ALLinONE and CUSTOM modules are guaranteed for two years from date of purchase. If they fail to 

perform correctly during 24 months from the date of purchase, Solbian undertakes to repair or replace them at its discretion, or 

to offer a refund. Repair, replacement or refund are the sole conditions offered by the warranty and cannot be extended beyond 

24 months.

RECYCLING AND DISPOSAL

Solbian is part of the European consortium PV-CYCLE, for the recycling of damaged or end-of-life modules, available in 

many European countries. SolbianFlex photovoltaic modules are electrical apparatus and must be disposed of accordingly, 

according to the laws of the country. In case of disposal requirements, please contact our sales department.

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 high efficiency boost converter 

with 4-phase interleaved topology

 with MPPT avoids the use of electrolytic capacitors, 

which can severely limit the system lifetime.

Solbian Charger 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 the 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 overtemperature.
