QB100-PV SS2 Solar Pump Inverter
Professional Single-Phase 220V Power Solutions | 1.5kW – 5.5kW
Single-Phase 220V Solar Pumping Made Simple
The QB100-PV SS2 Series is a high-efficiency MPPT solar pump inverter specifically engineered for standard single-phase 220V pumps. Unlike conventional VFDs that require complex capacitor removal and rewiring, the SS2 delivers stable power directly to your pump’s existing starting capacitor—eliminating installation headaches while providing 99% MPPT efficiency, intelligent dry-run protection, and seamless AC/DC hybrid switching for reliable residential and small-scale agricultural irrigation.
Key Industrial Features
🔌 No Capacitor Removal Required
- Direct-drive technology works with your pump’s existing starting capacitor—no internal wiring modifications needed.
- Simplifies installation and reduces electrical failure points.
- Compatible with standard single-phase induction motors (0.4kW-5.5kW).
⚡ 99% MPPT Efficiency
- Advanced maximum power point tracking maximizes water yield even in cloudy or low-light conditions.
- Wide DC input range up to 450V compatible with standard solar string configurations.
- Battery-free direct solar drive eliminates storage costs and maintenance.
🛡️ Advanced Soft Start & Protection
- Eliminates high inrush current to protect motor windings and extend pump lifespan.
- Sensor-free dry-run detection automatically stops pump when well is empty—no external sensors required.
- Overvoltage, undervoltage, and thermal protection for robust outdoor operation.
🔄 Seamless AC/DC Hybrid Switching
- Automatic switching between solar DC and 220V AC grid/generator backup power.
- Ensures 24/7 water availability regardless of weather conditions.
- Unattended operation with auto-start at sunrise and auto-sleep at sunset.

Frequently Asked Questions
Do I need to remove my pump’s starting capacitor when using this inverter?
No. The QB100-PV SS2 Series is uniquely engineered to work with your single-phase pump’s existing starting capacitor—unlike conventional VFDs that require complex capacitor removal and rewiring. This “capacitor-keep” technology simplifies installation, maintains original pump protection characteristics, and reduces electrical failure points. Simply wire the inverter between your solar array and pump—no motor modification needed.
Can I use this inverter with a diesel generator for backup power?
Yes. The QB100-PV SS2 supports seamless dual-mode AC/DC input. When solar irradiance is insufficient (nighttime, heavy cloud cover, or rainy seasons), the inverter automatically switches to 220V AC input from grid power or a diesel generator. This ensures uninterrupted irrigation schedules while maximizing solar usage when available—effectively eliminating fuel costs during daylight hours.
Is this unit suitable for outdoor installation without additional enclosure?
While the QB100-PV features robust industrial-grade construction with built-in thermal management, we recommend mounting in a ventilated weatherproof enclosure to achieve IP65-grade site protection. This ensures optimal cooling performance and protects against direct rain, dust, and UV exposure—extending service life in harsh agricultural environments. The compact design fits standard electrical boxes and pump house installations.
What size solar panel array do I need for my 2.2kW pump?
For the QB100-2R2G-SS2-PV (2.2kW) model, we recommend a 3000-3500 Wp solar array (typically 6-8 x 450W panels wired in series). The inverter’s wide 450V DC input maximum accommodates standard string configurations. Oversizing the array by 20-30% ensures sufficient power during morning/evening operation and cloudy conditions. Our engineers provide free PV sizing calculations based on your specific pump duty cycle and location irradiance data.
