Does the 11PV 7.5KW three phase solar pump inverter require batteries to operate?

No. The 11PV is a battery-less solar pump inverter that operates directly from solar panel DC input (486-750V) or 380V AC grid power. It converts energy in real-time to drive your 7.5KW three phase pump motor, eliminating the cost and maintenance of battery banks. The >99.6% MPPT efficiency ensures maximum power extraction from your PV array, delivering water when the sun shines without energy storage overhead—perfect for commercial farms and agricultural irrigation systems.

Can this 7.5KW three phase inverter run my existing 380V 10HP pump?

Yes. The 11PV-7K5GB-4T is specifically rated for 7.5KW (10HP) three phase 380V pumps. It supports both PMSM (Permanent Magnet Synchronous Motors) and standard asynchronous (induction) motors, outputting three phase 380V at 0-600Hz. The 17A rated current provides substantial starting torque for deep well submersible pumps, large surface centrifugal pumps, and extensive commercial irrigation systems. For pumps above 10HP, upgrade to our higher capacity 4T series models (11KW-160KW).

What is the difference between 2S series (220V single phase) and 4T series (380V three phase) models?

The 2S series is designed for single phase 220V pumps with a lower DC MPPT voltage range of 260-375V, making it ideal for residential and small-to-medium farm applications with standard household electrical infrastructure (max 11KW). The 4T series supports three phase 380V pumps with a higher MPPT range of 486-750V for commercial and industrial applications ranging from 0.75KW to 160KW. Choose 2S for residential/small farm 220V pumps; choose 4T for commercial/industrial three-phase pumps requiring higher power and efficiency.

What happens when solar power is insufficient or during cloudy weather?

The 11PV features intelligent AC/DC seamless switching. When connected to 380V AC grid power, it automatically supplements or switches to grid supply when solar irradiance drops. In pure solar mode, the inverter enters auto sleep mode when DC input falls below the minimum operating threshold (approximately 486V), then resumes operation automatically when sunlight returns. The optional clock relay card allows scheduling pump operation during peak solar hours to maximize efficiency and water delivery for your commercial farm or agricultural application needs.

How does the water level control system protect my pump?

The dedicated water level control port accepts float switch or pressure sensor inputs. If the water source (well, tank, or reservoir) drops below safe operating levels, the inverter immediately executes dry-run protection to stop the pump, preventing seal damage, overheating, and impeller wear. The system can also interface with storage tank level sensors to enable automatic fill control—stopping when full and restarting when levels drop, enabling true 24/7 unattended operation for commercial water supply and agricultural irrigation systems.
