There's no problems here. Everybody would like to know how your Sany performs. There are more people in your shoes than with money burning a hole in their pockets.

I have run 2 Sanys. the sy50u that I rented to demo the machines, and the one I bought. the "big" names had nothing to purchase, and if they had one it was thousands more. the $$ I saved went towards a steelwrist tiltrotator. been running it since feb with zero issues, now 525hrs on it. the only 'complaint' I would have is that it being a true zero tailswing it is a bit tippy over the side. I found that with the rental I demo'd thumb and pail loading trucks as well as with the tiltrotator setup on mine. so far there is nothing worse on this thing then any other excavator I have owned or run, and in many ways it is better.

Late reply, but for SANY electrical/hydraulic faults I would first lock down the exact machine identity before chasing solenoids.
On this type of case I would ask for or record:
- clear serial/PIN plate and engine plate photos
- exact model confirmation, because a handwritten or copied model can easily be SY205C/SY215C instead of what is typed on a message
- pump nameplate, main control valve tag, solenoid valve part numbers and photos of each connector
- controller/ECU label, fuse/relay box photos and harness plug photos
- which functions are weak: boom, arm, bucket, travel, swing, pilot lock or all functions
- coil resistance and supply voltage at each solenoid before replacing parts
- a short video showing engine rpm, hydraulic sound and the failed function at the same time
A generic manual can help, but the serial range matters. If the manual, valve tag and harness layout do not match the machine, it is easy to replace a good solenoid and miss the real problem: pilot pressure, wiring, controller output, stuck spool or pump control. I would build a photo file of the tags first, then compare it against the correct SY series shop manual.
