SOLAR INDUSTRY AWARDS I WINNERS


MODULE MANUFACTURING INNOVATION AWARD


LG Electronics Deutschland GmbH MonoX ACe


THE MonoX ACe from LG Electronics is a breakthrough by combining solar module and inverter for an alternating current (AC) power output (220 V). 1. The high- efficiency solar module rated 300 W has included an inverter/micro-inverter which is permanently installed at the back side of the module.


This inverter directly converts the direct- current (DC) power from the solar module into alternating current (AC) power. 2. With the inverter on the backside the known junction box with the bypass diodes is also included and can be saved in production. 3. The usual installation of an external micro-inverter is not necessary any more as it is already integrated in the junction box of LG’s AC module


The innovative approach of the new LG Electronics AC Solar Module differentiates in 3 ways. a) For the string inverter design the solar module with the lowest current determines the performance of the string. With the micro-inverter each solar module contributes its own maximum performance to the system. b) With the micro-inverter there is no need to spend material, costs, and time to install the individual inverter for the module as it is already permanently installed at the


module. c) The micro-inverter of the LG Electronics AC Solar Module can deliver from the DC input power (280 W) the same amount of AC output power (280 W), the world best output power. d) LG Electronics provides the total solution (i.e. module + integrated microinverter) and fully warrants the total system.


This reduces purchasing complexity for LG Electronics customers as a “one stop shop.”
