Frequently Asked Questions
Does the 11PV 37KW require batteries for large-scale irrigation?
No batteries are required. The 11PV-037G-4T is a direct-drive solar pump inverter that operates directly from PV panel DC power (486-750V range), converting to 380V three-phase AC for pumps up to 37kW. The integrated AC/DC hybrid input allows automatic switching to grid power when solar is insufficient, ensuring 24/7 operation without costly battery banks. For a 37kW system, this eliminates $50,000+ in battery capital expenditure.
Can this 37kW inverter handle my large submersible pump for deep wells?
Yes. The 11PV-037G-4T delivers 75A rated current (112.5A peak for 60 seconds) at 380V three-phase, supporting submersible pumps up to 37kW (50HP). It supports both PMSM (Permanent Magnet Synchronous Motors) and standard asynchronous motors with automatic parameter detection. For deep wells over 150 meters, the 150% torque boost during startup ensures reliable pump initiation. Vector control mode provides precise speed regulation for high-head applications.
How does the WiFi monitoring and water level control work?
The integrated WiFi module connects to a dedicated mobile app, providing real-time monitoring of PV input voltage (486-750V), output current (75A), pump frequency (0-600Hz), and system power from anywhere with internet access. The dedicated water level port accepts float switch or pressure sensor inputs to enable automatic tank filling—pump starts when water is low and stops when full, preventing overflow and dry-run damage. GPRS option available for remote farms without WiFi coverage.
What solar array size do I need for 37kW pumping?
For the 11PV-037G-4T, install approximately 46-50kW of PV capacity (125-135% of pump power) for optimal performance. Recommended configuration: 550W panels × 14 panels × 6 strings = 46.2kW total, producing 630V DC (within 486-750V MPPT range). At 5 peak sun hours daily, this produces 230kWh—enough to pump 2,000+ cubic meters at 50m head. Contact our engineers for precise sizing based on your well depth, flow rate requirements, and local solar irradiance data.
