Duty context for “1hp water pump inverter”
Select 1HP (~0.75kW) drives by motor phase and solar vs grid; avoid assuming every 1HP inverter matches your winding. Confirm the motor nameplate before choosing a frame — HP search terms often hide single-phase vs three-phase mismatches.
Solar vs grid at this power class
Off-grid daytime watering needs a solar pump inverter with MPPT. Grid constant-pressure needs a pump VFD with PID. Hybrid AC backup helps when clouds cut PV mid-day.
Array and protection still matter at small kW
Cold Voc must stay inside the inverter window. Dry-run and tank stop still protect shallow wells. Long thin cables waste voltage even on 0.5–3HP pumps.
Boray series mapping
BR600-P / BR500-P are typical solar pump answers once phase and current are confirmed; FS200/FS300 when the duty is grid pump control.
Next step
Photo the motor plate and state solar or grid for your “1hp water pump inverter” enquiry.
