Frequently Asked Questions
Q: Does this 2.2kW solar pump inverter require batteries to operate?
A: No. The 11PV-2K2 is a direct-drive solar pump inverter that converts DC solar power directly to AC for your 3HP pump motor—no battery bank required. The AC/DC hybrid function automatically switches to grid AC power when solar irradiance drops below pump demand, ensuring continuous operation while eliminating battery costs, maintenance, and replacement cycles.
Q: Which model do I need for my 2.2kW three-phase submersible pump?
A: Select the 11PV-2K2GB-4T (5.1A, 380V three-phase output) for standard asynchronous motors, or 11PV-2K2GB-4T-M if using a high-efficiency PMSM permanent magnet motor. Both models accept 486-750V DC solar input. For single-phase 220V pumps, choose the 11PV-2K2GB-25-M (10A output, 260-375V DC input).
Q: How does the water level port protect my pump from dry-running damage?
A: The dedicated water level sensor input connects to a float switch or submersible probe to monitor source water levels. When water falls below the safe threshold, the inverter immediately stops the pump—preventing cavitation, impeller damage, and motor overheating. The system automatically restarts when water levels recover, protecting your borehole or well pump investment.
