(4) To fully optimize the PV DC output set-up, use the following configuration guidelines: (a) For PV DC output less than 8.5 A, use a single pair of PV-Inverter DC terminals. (b) For PV DC output between 8.5 A and 17 A, use two sets of inverter DC terminals. (c) For PV DC output between 17 A and 25.5 A, use 3 sets of inverter DC terminals. 5.5 Connecting to the connection unit The AC connection unit is an interface between your PV-Inverter and the Public grid.
5.6 Installation checklist (1) H igh voltages exist when the PV-Panel is exposed to the sun. Exposed terminals of the PV-Panel are alive, and can cause electric shock. Avoid making physical contact with live parts of the device. (2) A fter the PV-Panels are connected to the PV-Inverter, the output voltage is higher than 100 VDC and the AC grid is not connected to the inverter, the LCD displays “Model= XXXXXX”-> “Waiting”-> “No Utility”. The RED “fault LED” turns on.
The PV-Inverter is feeding power to the grid, and the green LED displays. Before connecting the PV-Panels to DC terminals, make sure the polarity of each connection is correct. An incorrect connection could damage the device permanently.
6. Operation of the Protect PV 4600 LCD Display Function Button Power-on LED Fault LED 6.1 Auto-power The PV-Inverter starts up automatically once DC-power from the PVPanel is sufficient. There are 3 modes of operation. 6.2 Operating Modes 1. Normal In this mode, the PV-Inverter automatically detects the system status and selects the best mode of operation. If the power from the PV-Panel is higher than 150VDC, the supply is converted to AC and fed in to the grid.
2. Fault The PV-Inverter’s intelligent controller continuously monitors the system status. Unexpected conditions such as grid problems or internal failures are displayed on the LCD and the “Fault LED” turns on. Faults are indicated by the red “FAULT” LED. 3. Shutdown At the moment of reduced sunlight, the PV-Inverter automatically shuts down. No power is used from the grid, the LCD display and LEDs on the front panel do not work, and the function button is inactive. 4.
Before connecting PV-Panels to DC terminals, make sure the polarity of each connection is correct.
