Does the 11PV solar pump inverter require batteries to operate?

No. The 11PV is a battery-less solar pump inverter. It operates directly from solar panels (DC input) or AC grid power, converting energy in real-time to drive your pump. This design significantly reduces system cost and maintenance while maximizing efficiency through direct PV-to-pump energy transfer with >99.6% MPPT tracking accuracy.

Can this inverter run my existing 3-phase 7.5KW pump motor?

Yes. The 11PV-7K5GB-4T supports both PMSM (Permanent Magnet Synchronous Motors) and standard asynchronous (induction) motors. It outputs 3-phase 380V at 0-600Hz frequency range, making it compatible with most standard 7.5KW (10HP) submersible or surface pumps. The vector control mode ensures smooth starting and optimal torque delivery for deep well applications.

What happens when solar irradiance is low or at night?

The 11PV features seamless AC/DC switching. When solar power is insufficient, it automatically switches to AC grid power (if connected) to ensure continuous pumping. In pure solar mode, it enters auto sleep mode when irradiance drops below operational thresholds, then wakes automatically when sunlight returns. The optional clock relay card allows programming specific operating schedules to match water demand with solar availability.

How does the water level protection work?

The built-in water level control port accepts sensor inputs to monitor source water levels. If the water source drops below safe levels, the inverter triggers dry-run protection to immediately stop the pump, preventing damage to seals and impellers. It can also interface with tank level sensors to enable automatic fill-level control, stopping when tanks are full and restarting when levels drop.
