Asia’s rapid urbanization and renewable energy push create strong demand for efficient, scalable, and intelligent inverters.
India & Bangladesh: Frequent voltage fluctuations and scheduled power cuts. The EM’s wide input voltage range (90–280VAC) and 10ms transfer time protect sensitive electronics in homes and small businesses.
Vietnam & Thailand: High humidity and tropical storms. The detachable dust cover and moisture-resistant design ensure durability, while dual MPPT optimizes solar harvest on shaded or multi-orientation rooftops.
Japan & South Korea: High energy standards and space constraints. With PF=1.0 and compact design, the EM series meets stringent grid codes and fits easily in residential or commercial installations.
Philippines & Indonesia: Island communities and off-grid tourism. Lithium battery activation via PV enables easy system startup, and WiFi monitoring allows remote management across scattered locations.
Key Advantage: Dual MPPT allows two separate PV arrays, ideal for rooftops with uneven shading or different orientations—maximizing energy yield in space-constrained urban areas.
