7.4 Under normal conditions, the current and voltage values generated by the modules may be higher than the standard test
conditions of the component. Therefore, when designing PV power system components, such as rated voltage, wire
capacity, fuse capacity or component power output related parameters, the corresponding short-circuit current and open
circuit voltage should be amplified by 1.25 times.
7.5 Use limit: Do not install or use modules in corrosive areas, under abnormal environment conditions, or on mobile units
(except solar tracking mounting systems are allowed). Should connect the negative pole (of the array) to ground , cause it
can reduce the risk of PID. Doing so will void the product warranty.

The current and voltage characteristics of Motech modules are within -5%/+10% percent of the indicated values of Isc and Voc
under standard test conditions (irradiance of 1000 W/m
2
, AM 1.5 spectrum, cell temperature of 25°C). The maximum power of
each Motech module is within -0% / +3% of the indicated values of rated power under standard test conditions. Other
tolerances may be available upon special request.
9. Bypass diode
9.1 Bypass diodes are pre-installed in the junction box of each Motech PV module. Depending on junction box type, each
junction box model provides 3 Schottky diodes with a maximum current of SB3050DY of 30 Amps. Each bypass diode is
rated at 50 Vdc reverse voltage.
9.2 Each bypass diode is connected to 1/3
rd
the total number of cells for a given module type. Bypass diodes are NOT user-
serviceable components. DO NOT remove bypass diodes or operate a module without bypass diodes.
