Does the 11PV 5.5KW single 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 (260-375V) or 220V AC grid power. It converts energy in real-time to drive your 5.5KW single 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 large residential estates and medium-to-large farm applications.

Can this 5.5KW single phase inverter run my existing 220V 7.5HP pump?

Yes. The 11PV-5K5GB-2S is specifically rated for 5.5KW (7.5HP) single phase 220V pumps—the maximum capacity for 2S series. It supports both PMSM (Permanent Magnet Synchronous Motors) and standard asynchronous (induction) motors, outputting single phase 220V at 0-600Hz. The 24A rated current provides substantial starting torque for deep well submersible pumps, large surface centrifugal pumps, and extensive irrigation systems commonly used in large farms and estates. For pumps above 7.5HP, upgrade to our 4T series (380V three-phase).

Is 5.5KW the limit for single phase 220V solar pump inverters?

Yes, 5.5KW (7.5HP) is the maximum practical capacity for single phase 220V systems due to current limitations (24A) on standard residential electrical infrastructure. The 11PV-5K5GB-2S represents the top of our 2S series line. For higher power requirements (7.5KW-160KW), our 4T series offers three-phase 380V solutions with MPPT range of 486-750V. Contact our technical team to discuss upgrading to three-phase power if your pump exceeds 7.5HP.

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

The 11PV features intelligent AC/DC seamless switching. When connected to 220V 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 260V), 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 large property or farm 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 large residential water supply and extensive irrigation systems.
