For example, if the max current of your load device is 10A. Then choose 10A/0.8=12.5A at least for resistive loads according to international standard. And also you could choose 15A or 20A. If the load device is motor or compressor, then you may choose 10A/0.5=20A.According to real testing result since the motor and compressor starting current may be 2-3. The input cable and output cable should be enough big for current and length less 2m. The input side should connect an 160A fuse and the fuse is not included. Or it damages the converter. Never connect this converter to solar panels directly as a solar controller. Never make this converters in parallel. Never use this converter in tele-communication, medical, aerospace and military. If you need that request. Turn off all power and load. Install copper terminal lug for all cables. Connect GND to LOAD- and OUTPUT+ to LOAD+. (Don't connect the GND to Vehicle Ground). Insert 160A fuse in input cable, then connect GND to BAT- and Input+ to BAT+. Check all polarity and fix all connection stably. Turn on power and converter works.
Notes: There may be a spark when you connect the terminal and it's normal. Wide input voltage from 11V to 16V.Stable output voltage is 24V. 100% full stable output Current. Cooling by free air convection.
