Permanent-magnet brushless motor + intelligent MPPT (auto start/stop, soft-start)
Controller LED display: voltage / current / power / speed (RPM) / error code
Oil cooling
Full protection: over/under-voltage, overload, over-current, dry-run, reverse, over-temp
Runs directly off PV modules — no batteries required
Progressive-cavity screw + SUS304 sleeve — well-suited to sandy / silty water
