9. ystem electrical connections It is not recommended to use modules with different configurations and electrical characteristics in the same system Modules can be connected in series to obtain a high operating voltage The system voltage is equal to the sum of the voltage of each module Modules can also be connected in parallel to obtain a high operating currents The system current is equal to the sum of the current of each string of modules The maximum number of series connected modules depends on system design the type of inverter used and environmental conditions It should be noted that modules must not be connected together to create a voltage higher than the permitted system voltage There is no limitation on the number of modules that can be connected in parallel the number of modules is determined by system design parameters such as current or power output 6 2 Grouding Grouding modules is necessary to reduce or eliminate shock and fire hazards All module frames and mounting racks must be properly grounded in accordance with local and national electrical codes Proper grounding is achieved by connecting the module frames and mounting racks continuously using a suitable grounding conductor The grounding conductor or strap may be copper copper alloy or other material acceptable for use as an electrical conductor Worldwide Energy and Manufacturing USA Co LIMITED Sen Add RM 1708 C1 NAN FUNG TOWER wae 173 DES VOEUX RD CEN
