Check the listing for details. 2800W Solar Grid Tie Micro Inverter, 120/240Vac GridOutput, 18-60Vdc Solar Input. Color: Blue & Orange, Condition: New. Listed at 380.00 USD. USA household grid is Split Phase, i.e, 120Vac and 240Vac. This inverter supports both. When connected to the grid 240Vac, the current is halved that compare to connection to 120Vac. Lower current allows use of thinner electrical wire, lowering wire cost and electrical fire risks. For 120 Vac to grid, just connect the cable from inverter to any USA household socket. Advantages over competitors: Using one of this inverter, your wiring decides types of output, either 120Vac or 240Vac. Compeitors would required two of their units to achieve 240Vac, raising system cost and points of failure. MPPT is centralized in this inverter. You do not need an optimizer for each solar panel, e.g, SolarEdge inverters won't work without optimizer at each panel. This inverter's MPPT centralizes and optimizes power generated by panels. Future proof your lower wattage inverter, eg, 1000W to be upgraded to 3000W. This inverter will future proof your lower-wattage system, lowering total system cost over time. Wifi monitoring of current and historical power generated. Not all competitors' inverter has this feaure. Better heat dissipation and waterproofing, achieiving IP66 level. How to connect inverter's AC 3 output pins (Live, Neutral, Ground) to L1, L2, Neutral, Ground of the grid: For 120 Vac: L-L1, N-N, G-G; or L-L2, N-N, G-G 240Vac: L-L1, N-L2, G-G, see picture Monitor power generation using SmartLife App for cellphone that provide current and historical energy output views, etc. 2024 model, better heat dissipation and waterproofing than older competitor models, e.g., WVC Model 2800W Input Data (DC, PV) Number of Input MC4 Connector 4 sets MPPT Voltage Range 22V-48V Operation Voltage Range 18V-60V Maximum Input Voltage 60V, higher voltage allows use of thinner wires Startup Voltage 22V Maximum Input Power 2800W Maximum input Current 16A*4 Output Data(AC) Single-Phase Grid Type 120V&230V Rated Output Power 2800W Maximum Output Power 2800W Nominal Output Current @120VAC:16.6A/@230VAC:8.6A Nominal Nominal Output Voltage 120VAC /230VAC Default Output Voltage Range @120VAC:80V-160V /@230VAC:180V-270V.
