StecaGrid - Model 1800 - Grid Inverters Brochure

DC circuit breakerStecaGrid ALD1Digital energy meter 71 176243StecaGrid 300StecaGrid 500StecaGrid 300 and StecaGrid 500The inverters series comprises the StecaGrid 300 and StecaGrid 500 inverters, with rated outputs of 300 W and 500 W, respectively. StecaGrid 300 and StecaGrid 500 are built in a modular manner, and simple to install. With distribution over three phases, the system can at any time be expanded as desired, and thus flexibly adapts to your solar power system investment. StecaGrid 300 and StecaGrid 500 have an independent MPP tracker and achieve a very high effi-ciency of up to 95.8 %.
