The one protection they don't have is over-voltage.
Except Midnight Solar, with "Hyper VOC" feature.
Make sure that with Voc and temperature coefficient of Voc from PV panel data sheet, record coldest temperature of your location, adjust from nominal 25 degree condition where Voc is spec'd, it will never exceed max input rating of equipment.
Some systems do have protection mechanisms built in, in which case they have a hard and fast rule on max short circuit current. Because that's their backup plan.
Just don't exceed those specs. Exceeding wattage recommendation is commonly done, however.
The equipment will log highest voltage, just so manufacturer knows to deny warranty claim.
