Page 20: System Diagram
4. System Diagram The typical connection diagram for the entire PV system is shown in the following figure. PV Panel: Provide DC power to inverter PV-Inverter: Converts DC (Direct Current) power from PV panel(s) to AC (Alternating Current) power. Because the PV-Inverter is grid-connected it controls the current amplitude according to the PV Panel power supply. -
Page 21: Operation Of Pv-Inverter
5. Operation of PV-Inverter Modes of operation There are 3 different modes of operation. 1. Normal mode: In this mode, the inverter works normally. Whenever the supplied power from PV panel is sufficient (voltage>150VDC), inverter converts power to the grid as generated by the PV panel. If the power is insufficient (voltage<120VDC), inverter enters a “waiting”... -
Page 22: Front Panel
Front Panel Operating PV-Inverter is quite easy. During normal operation, the inverter runs automatically. However, to achieve maximum conversion efficiency of inverter please read the following information: Automatic ON-OFF: PV-Inverter starts up automatically when DC-power from the PV panel is sufficient. Once the PV-Inverter starts it enters one of the following 3 states: Standby: The PV string can only provide just enough voltage to minimum requirements of the controller. - Page 23 information. Each subsequent press changes the display. The display sequence is shown in panel LCD display sequence figure on next page. Hold display: If you want to hold a specific display. Repeatedly press the function key until the desired display is reached. Release the key and press again for more than 1 second until you see “Lock”, release the key;...
