EP500 aviation cable solar limits!

Hey guys, today i got my EP500 but i have a problem with solar charging, right now i have a 550watt solar panel with max 50V but the EP500 need at least 55V to start charging from the solar panels so must increase the voltage. My question is can avoid the second panel right now and boost the voltage over 55? And if i buy second panel and connect it in series the aviation cable from bluetti can handle all this power with only two of the four mc4 cables or i have to add new cables from my roof to my room?

Here the link from my solar panel: 530-550W Solar Panel-Mono Solar Panel-Exporter-Solarborn
