4 Installation instructions for 50KW off grid photovoltaic system: (below is for reference only ,different project has different detail diagram))

1. Photovoltaic panel installation: Every 11 photovoltaic panels are connected in series, divided into 10 groups. The connected photovoltaic panels are connected to the corresponding combiner box, which then connects to the PV wiring port on the MPPT controller;

2. MPPT controller installation: PV+is connected to the input positive pole of the photovoltaic panel, PV - is connected to the input negative pole of the photovoltaic panel, BAT+is connected to the positive pole of the bitter battery pack, and BAT - is connected to the negative pole of the battery pack. The positive and negative poles cannot be reversed or shorted,

3. Battery installation: The battery is connected to the DC Input port on the inverter, with+being the positive pole and - being the negative pole. The positive and negative poles cannot be reversed or shorted; 

4. The inverter configured in this system has a mains bypass function, so it can connect mains power to the ACInput port. When the battery is low, the inverter will automatically switch to mains power to continue supplying power to the load; 

5. The AC OUTPUT port of the inverter is an AC output port that can be connected to AC loads. 

6. The data cable of the display screen system is connected to the RS232 interface on the inverter.
