100% brand new, high qualiy. Model:GMI300, GMI500, GMI600 , GMI700. Grid Tie Inverter MPPT Range 24-40V. Vmp(of a solar panel) must be in the MPPT range to ensure the good output efficiency Recommended Solar Panel Voltage: Vmp30-39V; Voc38-46V Solar panel power cannot exceed 300W/350W/500W/600W/700W Micro Grid Tie Inverter Doesn’t work with battery. Grid Tie Microinverter is a compact unit, which directly converts direct current into alternating current for powering appliances and/or office equipments and connecting to utility grid. The AC output from Smart Micro inverter is synchronized and in-phase with the utility grid. Installation Procedures: Step 1- Attaching the micro inverter to the racking. Mark the location of the micro inverters on the rack, with respect to the PV module junction box or any other obstructions. Mount one micro inverter at each of these locations using hardware recommended by your module racking vendor. Step 2- Connect the micro inverter AC cable and connect to AC bus cable (L-brown, N-blue, G- green&yellow) one by one, please do not exceed the maximum current of AC bus cable. Step 3- Connect micro inverter to the PV module, please do not exceed PV panel(s) VOC over inverter max. Step 4- Install the AC branch circuit junction box, wire the conductors of the AC bus cable. Connect the AC branch circuit junction box to the point of utility-grid Interconnection. Step 5- Double check all micro inverter, connectors and cables are correctly and well connected. Step 6- Turn on the AC circuit breaker on each AC branch circuit of micro inverter. Step 7- Turn on the main AC circuit breaker of utility-grid. Your system will start producing power after a 30 sec safety delay period. Green light steady: micro inverter in generating. Red flash: micro inverter in waiting. Red light steady: a.
