www.JFY-tech.com11 Check the secure mounting of the solar inverter by trying to raise it from thebottom. The solar inverter should remain firmly attached. Choose a strong mounting wall to prevent vibrations while inverter isoperating.2. 4 Sy s t e m D i a g r a m an d C o n n e c t i o n La b e lThe JSI series are a single phase solar inverters. They are responsible forconverting the direct current generated by PV panels into single-phase 230Vac50Hz alternating current for delivery into the AC grid.The JSI series can be used in an on-grid PV system to produce electricity.The installation of the JSI series and their connection to the AC grid shall bedone in accordance with local regulations and may require the installation ofadequate electricity consumption measuring devices.The JSI series only operates when it is connected to the AC grid and can notoperate as a stand-alone unit.The simplified connection diagram of the inverter is as follows.Fig.6 The PV system diagramA. PV Panels: Provide DC power to inverter.B. Solar inverter: Converts DC (Direct Current) power from PV panel(s) to AC(Alternating Current) power. Because Inverter is grid-connected it controls thecurrent amplitude according to the PV Panel power supply. Inverter alwaystries to convert the maximum power from your PV panel(s).C. DC Switch and AC Switch: “DC switch” is between PV Panels and solarinverter while “AC Switch” is between AC Grid (Utility) and solar Inverter. Theyare be simplified in this diagram. In fact, they may consist of electrical breaker,fuse and connecting terminals. To comply with local safety standards andcodes, the connection system should be designed and implemented by aqualified technician. JFY-tech also provides the solar inverter with anintegrated DC switch demonstrated in dashed border in Fig.6. –S suffixindicates the inverter is integrated a DC switch in PV input side.D. AC Grid (Utility): Referred to as “grid” in this manual, is the way your electricpower company provides power to your place. Please note that Inverter canonly connect to low-voltage systems (namely, 220/230Vac, 50Hz). |
