Electrical configuration

• The key electrical data for the MBI modules is provided in the product data sheets at: https://www.meyerburger.com/.

• Meyer Burger modules have three pre-installed bypass diodes (non-exchangeable) that guarantee protection and improved performance in case of shade.

• Only modules from the same line and performance class can be interconnected.

• Under normal conditions, all Meyer Burger solar modules are likely to produce higher current and/or voltage than reported at standard test conditions.
  . A safety factor of at least 1.25 for the electrical values (Voc, Isc) shall be used for determining component voltage ratings, conductor current ratings, and size of controls connected to the PV output.

•  Meyer Burger Glass modules are bifacial solar modules with a bifaciality factor as specified in the module data sheet (www.meyerburger.com).
  Dependent from the specific conditions of the installation site (e.g. reflectivity of the ground or roof surface) Meyer Burger Glass modules additionally collect energy from the received rear irradiation. Therefor all components of the electrical system must be correctly dimensioned by a qualified person in accordance with the relevant regulations and site-specific conditions.

• We recommend using UV-resistant PV cables. They must have a cross-section of at least 4 mm2 (12 AWG) and be heat-resistant at least up to 90°C (194°F).

• Choose identical connectors (same manufacturer, same connector family) for extension and connection cables and for module to module connection. Meyer Burger modules use different connector types. Those types are marked with a number on the module lables. The identification of the numbers can be found on the data sheet and in the installation manual on page 4.

• Avoid shade to achieve optimal solar irradiation and thus maximize yield.

• The individual system components (modules, fuses, inverters…) must be matched according to their data sheets.

• Observe the local, regional and national regulations on the installation of electrical systems.

Series connection

• The modules can be connected in series for the desired total voltage.
• The current (IrriPP ) of modules connected in series should be the same because the maximum current is determined by the module with the lowest current.
• The maximum system voltage must be observed and can be found in the table in the “Technical Data” chapter under “Maximum system voltage” or the data sheet for the corresponding module.

Parallel connection

• The modules can be connected in parallel for the desired total current.
• The voltage (Vmpp ) of the modules connected in parallel should be the same.
• Install overcurrent protection devices (OCPD) in accordance with the relevant standards and national codes. Please follow the guidelines in Article 690-8 and 690-9 of the NEC accordingly.
• Additional reverse-current protection (e.g. blocking diodes or fuses) must be installed in each module string if the possible reverse current exceeds the overcurrent protection rating of the modules.
• The overcurrent protection rating can be found in the module data sheet. The string fuse rating shall not exceed the overcurrent protection rating of the module.
• The cable cross-section of the extension cable must be matched to the maximum current of the connection.

Series–parallel connection

• The modules can also be connected in combination.
• All components must be matched and the individual connection instructions for series and parallel connectiontaken into consideration.
•  Connect the same number of modules in a series string (same string voltage).
•  Additional safety precautions are needed to protect the cables and modules from overcurrent.

Installation

Safety and transport
Handling the modules

• When handling the modules, always wear clean gloves and hold them by the module frame.
•  When unpacking the modules, the front side must be protected against scratches, etc.
•  Do not short-circuit (couple) the solar module cables under any circumstances.
•  Do not move or carry the modules by grabbing the cables.
•  Do not step on the modules.
• Do not place heavy objects on the modules (e.g. tools or tool boxes).

Installation site

Follow the instructions below for the installation site:

• The modules must not be installed:
•  in closed spaces.
• over 2,000 m above sea level *.
•  on water surfaces*.
•  inplaceswherewatermayaccumulate (e.g.duetofloods).
•  neareasilyflammablegasesorvapors (e.g.gastanksorgasstations).
•  atsiteswherecontactbetweenchemicalsubstances (e.g.oilandsolvent)andpartsofthemoduleispossible.
•  inthedirectproximityofventilationandairconditioning systems.
• Themodulesmustnotbeusedasasubstituteforroofing or facades.
• Ifinstallinglessthan500mfromthesea,specialprecautions regardinggrounding,maintenance,andcleaningare necessary.

Module orientation

•  The modules can be installed in portrait or landscape direction.
•  Make sure that there is no backwater. Rain and melted snowand ice water must be able to drain freely.
• Do not cover or seal off the water drains in the module frame.
•  The minimal tilt angle is 5°.
•  Observe the local regulations for the maximum tilt angle.
•  A tilt angle of more than 20° has a positive impact on the module’s self-cleaning capacity.

Shading
Optimal solar irradiation leads to a maximum energy yield:

•  Install the modules facing the sun.
•  Avoid shade and partial shade (e.g. from trees, chimneys, buildings, dirt, snow, power lines, etc.).
•  Avoid harsh shading on the back of the Meyer Burger Glass** modules trough racking system parts and unnatural high irradations trough concentrated reflections of the surroundings.

Racking
Racking requirements:

• The racking must meet the necessary structural requirements in accordance with the local snow and wind loads.

• Meyer Burger solar modules can be mounted in combination with UL 2730 certified mounting systems if listed.

•  Uneven snow loads (e.g. snow cornice, snow drifts) that lead to much higher local loads must be eliminated or prevented through technical measures.

• In addition to the wind and snow loads, no other forces must impact the module through the racking.

• The racking must be mounted on the roof or ground properly.
  *Assembly at altitudes of over 2,000 meters above sea level or on water surfaces can be planned in consultation with the manufacturer.
  ** UL certification pending

• The forcesactingonthemodulemustbetransferredtothe racking.

•  There may be no objects (air outlets, aerials, etc.) on the rear of the module that produce pressure concentrations during module deflection.

• The racking must ensure adequate cooling through rear ventilation of the module.

•  The mount should be free of tension to enable changes in length due to temperature.

•  Additional tensions and torques at the assembly points are not permitted.

•  Make sure that the clamps or slide-in profiles, etc. do not touch the glass, even in loading conditions.

• Make sure that there is a distance of at least 50 mm under the junction box to the racking and other hard structures.

• Make sure that the cables cannot become jammed between the laminate and the mounting rails under a high pressure load. We recommend laying the cable along the module frame.

• Avoid contact between different metallic materials (contact corrosion; refer to the electrochemical series).

• Use corrosion-resistant screws and washers for mounting.

• The fastening screws and washers should have the same material properties.
