太阳能水泵逆变器（控制器）SWP1K5H-E-V1 / SWP2K2H-E-V1

Q: Q1: What type of pump can this solar pump inverter drive?

A: It is designed for three-phase AC water pumps within the rated power range.

Q: Q2: Can the inverter work without batteries?

A: Yes. The inverter directly uses solar power and adjusts pump speed according to sunlight, eliminating the need for batteries.

Q: Q3: What happens if there is no water in the well?

A: The inverter automatically activates dry-run protection and stops the pump to prevent damage.

Q: Q4: Can I use grid electricity as backup power?

A: Yes. The system supports both DC (PV) and AC input, enabling flexible hybrid operation.

Q: Q5: Is this inverter suitable for remote installation?

A: Absolutely. It supports unattended operation, low maintenance, and stable performance in harsh environments.
