4.Functions 4.1 Brief D escription The GSI is a single phase grid-tied PV inverter, which is unlike to the stand-alone PV inverter in the sense that it does not need an external battery, which is expensive and bulky; furthermore reducing the sizeable cost of maintaining this battery. The GSI can effectively convert photovoltaic DC power harvested from the PV module to AC power which is fed back to the utility grid, reaching the goal of generating and conserving energy.
4. 5 Derating When the input voltage is low or when ambient temperature is high, the GSI-3000, 4600 will automatically derate the output.

5. 2 . 4 Permitted Mounting Position Please install in an upright position, do not lean forward, backward, or lay flat. 5.3 Wall Mounting 5.3.1 Install Wall Mounting Bracket Requirements : 1.Install only on vertical surfaces 2.Install on a firm surface 5.3.2 Installation Procedure 1.Use the mounting bracket as a template to mark positions then drill holes. 2.Insert the plastic anchors into the holes then screw the corresponding screws to fix the wall mounting bracket on the wall.
4.For more convenient maneuvering, please make use of the side handles. 5.Mount this GSI onto the wall mounting bracket. 6.Check the sides of the GSI for correct positioning. 7.Use the mounting bracket screw to fix the side holes of the GSI onto the wall mounting bracket.
8.Use the grounding screw to connect the grounding wire to the GSI. Grounding Position 5.4 Electrical Connections Warning! ◎Electrical connection should only be made after making sure the GSI-3000,4600 is thoroughly installed. ◎One circuit breaker should only be connected to one inverter, please do not connect multiple inverters with one circuit breaker.
5.4.2 Cable selection 1.Choice of wire diameter must follow safety rules which limit the particular wires to a maximum current flow. 2.It is advised to use wires of larger diameter to reduce transmission loss. 3.Use color coded cables to indicate the positive and negative terminals of the DC input. 4.Use color coded cables to indicate the line, neutral, and potential earth terminals of the AC output. Model GSI-3000 Max. Rated Input Current 1x16A Input Cable Cross-section(Typ.) 2.5mm Max.

5.5.1 Power ON 1.Inspect the DC switch in PV module distribution box, use a multimeter to measure if the input is within rated values (125~500V). Caution : When designing the system, the user must be mindful of the open circuit voltage when the ambient temperature is at its lowest; This voltage must not be greater than inverter ratings. 2.Inspect the AC switch on the distribution panel, make sure the utility grid's voltage and frequency is within typical range.
