Epever MPPT Controller RS285 cable...can I get a longer one ?

so i bought a 40A epever MPPT controller to manage a solar panel at my cabin. Due to sun, I placed panel and battery on my shed but would like to place the M50 remote unit in my cabin. BTW..I bought a 40A as I plan on installing up to 750W and wanted to not have to upgrade later.Unfortunately i need a longer cable and am having trouble finding one. I am looking for a approx 100' . The tag on the factory cable says "Model: CC-RS485-RS485-200U-MT   For LS-B, Tracer-B, VS-B controller ".  I am not an elec guy but hoping someone can help me source this. Thanks in advance..

    RS485 can go pretty long distances. 100 feet should be fine. Just use Cat3 or Cat5 Ethernet cable. (Make sure you keep twisted pair wires correct).

    What connectors are required?
