No batteries are required. The 100PV series operates with a direct solar-to-pump configuration, converting DC power from your solar panels directly to AC power for the pump motor. This eliminates the significant cost and maintenance of battery banks while maximizing energy efficiency. The system starts automatically when sufficient solar irradiance is detected and stops when light levels drop, protecting your pump from dry-running.

Yes, but this requires customization. The factory default setting accepts DC input only for asynchronous pump control. To enable simultaneous AC grid and DC solar input with seamless auto-switching capability, you must specify this requirement when ordering. This dual-input feature ensures your pumping system continues operating during cloudy periods or at night using grid power, then automatically switches back to free solar power when available.

The 100PV series supports both single-phase and three-phase pumps. Models with the “-2-” suffix (e.g., QB100-1R5G-2-PV, QB100-2R2G-2-PV) are specifically designed for three-phase motors. Single-phase variants are identified by “-SS2-” or “-S2-” in the model number. When ordering, ensure you select the correct phase configuration to match your pump motor. If you require a synchronous motor pump, please contact our technical team for customization options.

The integrated GPRS module connects to cellular networks, allowing you to monitor and control your solar pumping system via a dedicated mobile application from anywhere with network coverage. You can view real-time parameters including input voltage, output frequency, pump speed, power generation, and system status. The app also provides fault alerts, historical data logging, and remote start/stop functionality—reducing the need for on-site inspections and enabling rapid response to any operational issues.

SS2 models include boost module compatibility, which allows the inverter to step up lower voltage DC input to drive higher voltage pumps—particularly useful for 2.2kW systems where you want to minimize the number of solar panels required. S2 models are standard configurations without the boost feature. For most agricultural applications requiring cost optimization, we recommend SS2 variants as they provide greater flexibility in system design and can reduce total installation costs by up to 30% through optimized panel configuration.
