Description
The QB100-PV Series Solar Pump Inverter is a high-efficiency MPPT variable frequency drive (VFD) designed for heavy-duty agricultural and industrial water pumping. Operating without batteries, it converts DC solar power directly into 3-phase AC output to drive submersible and surface pumps from 45kW to 280kW—drastically reducing diesel costs and ensuring reliable irrigation in off-grid or hybrid environments.
Key Features & Benefits
⚡ 99% MPPT Efficiency

Frequently Asked Questions
Do I need batteries to operate this solar pump inverter?
No. The QB100-PV is a battery-free design. It drives the pump motor directly from solar panel DC input, significantly reducing system costs, maintenance, and complexity. This makes it ideal for agricultural irrigation where simplicity and reliability are critical.
Can this inverter work with my existing 3-phase pump?
Yes. The QB100-PV outputs standard 3-phase 380V/400V/440V AC power and is compatible with all standard 3-phase AC induction motors, including submersible pumps and surface centrifugal pumps. Simply match the inverter kW rating to your pump motor size.
What happens when there is no sun or at night?
The QB100-PV supports AC/DC hybrid input. When solar power is insufficient, it automatically switches to grid power or generator backup (if connected). Alternatively, it enters sleep mode at night and auto-restarts at sunrise—protecting your pump while maximizing solar usage.
How does the dry-run protection work?
The inverter uses sensor-free dry-run protection technology. It monitors motor current and power consumption to detect when the well is empty. If dry-run is detected, the system shuts down automatically to prevent pump damage and will retry periodically until water is available.
What is the warranty and technical support?
All QB100-PV inverters come with a 24-month warranty and lifetime technical support. Ideeishop provides installation guidance, parameter configuration assistance, and troubleshooting support. For project quotes or technical consultation, contact us directly.
