folks didnt have a charger/adaptor so they rigged this bluetti EB240 to run directly off solar panels. the input slot that got cut was labeled "DC16-60V/10A" or as written on the product information sticker "42Vdc, 10A ,500W max"

my question is whether this device can be ran safely off any solar panel(s) and whether the computer can process the irregular the input from the panels?, or does there need some sort of buffer system between the solar panel and the battery system?

my next question is what is this type of wire clamp connecting the yellow and pink wires, can it be reused to connect the circled yellow back to yellow where it was snipped?

thank you
