What buyers mean by “220v inverter for well pump”
Match 220V single vs three-phase labelling; keep dry-run and earthing at the well head. Write the motor phase and output voltage on line 1 of the RFQ so suppliers cannot guess.
Compatibility traps
Never assume a three-phase-only solar VFD will run a single-phase PSC motor. Either select a compatible drive or budget a motor change with engineering sign-off.
MPPT and VFD control expectations
If the PO says MPPT and VFD, require both: PV tracking under cloud edges and motor control with dry-run/tank logic. Adjectives without tests are not scope.
Boray notes
BR500-P / BR600-P cover solar pump duties in their rated voltage classes — confirm the datasheet current for your motor.
