Solar pumping inverter user manual1、Electrical cable ConnectionPlease follow the diagram below for wiring. And pay attention to the following issues： The power output of the PV panel is connected to the “+” and “-” terminals. Please note that thepolarity is not reversed. Make sure that the inverter input AC voltage level is consistent with AC grid voltage before connectingwith Input “R”, “S” and “T” terminals If Grid is single-phase power supply, you can connect to R T or any two terminals of “R”, “S” and “T”。 DI1 defaults to the running terminal input. AI2 defaults to the water tank level detection signal input, which is used to control the invertersleep and auto start. Relay 1 output defaults to the fault signal output.1.1 Electrical SpecificationsTable 1-3 Electrical Specifications220V 380VMax input DC voltage 450V 810VRecommended MPPT voltage range 150~410VDC 250~800VDCRecommended input voltage 305V 530VMPPT efficiency >99%Input channel 2Rated output voltage 1/3-phase 220VAC 3-phase 380-480VACOutput frequency range 0~60HzMax efficiency of the machine 99%Ambient temperature range -10 °C~50 °C, derating if the temperature is above 40 °CCooling method Air coolingProtection degree IP20/IP21Altitude Below 1000m; above 1% for every additional 100m.Standard CENoted: We suggest solar panel power should be 1.2-1.35 times higher than solar pump power ,and solarpump inverter power should be same or higher level than solar pump. When solar pump distance toinverter higher than 100m,it should be equipped with Output reactor or higher level power inverter .forSolar pane,l total VOC less than Maximum DC voltage of inverter and Solar panel vmp is recommend 530Vfor 380V pump and 305V for 220V pump
