Frequently Asked Questions
Does the 11PV 2.2KW 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 2.2KW 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 residential and small farm applications.
Can this 2.2KW single phase inverter run my existing 220V 3HP pump?
Yes. The 11PV-2K2GB-2S-M is specifically rated for 2.2KW (3HP) single phase 220V pumps. It supports both PMSM (Permanent Magnet Synchronous Motors) and standard asynchronous (induction) motors, outputting single phase 220V at 0-600Hz. The 10A rated current provides sufficient starting torque for residential submersible pumps, surface centrifugal pumps, and small irrigation systems commonly used in homes and small farms.
What is the difference between 2S series (220V) and 4T series (380V) 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-scale applications with smaller PV arrays. The 4T series supports three phase 380V pumps with a higher MPPT range of 486-750V for industrial and large agricultural systems. Choose 2S for household water supply and small farms; choose 4T for commercial irrigation and industrial pumping operations.
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 household 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 residential water supply and small irrigation systems.
⚠️ Installation Requirements
