Solar Pump Inverter A-Series: A Comprehensive Report > 자유게시판

The AC output stage of the SN2200 is a pure sine wave inverter rated at 2.2 kW. The output voltage is a three-phase, 380V AC at 50 Hz or 60 Hz, depending on the regional configuration. The output current capacity is approximately 5.5 Amperes per phase. The inverter is capable of driving both two-wire and three-wire (with neutral) submersible pumps. It uses a variable frequency drive (VFD) technique, which allows soft-start operation. This feature is critical for submersible pumps because it reduces mechanical stress and prevents water hammer effects, extending the pump's operational lifespan. The VFD also enables the pump speed to be adjusted based on solar power availability; on cloudy days, the pump runs at a reduced speed rather than stopping entirely, thus maximizing water output throughout the day.

From an operational standpoint, the NV inverter's automatic control and monitoring capabilities reduce the need for on-site personnel, lowering labor costs. The hybrid power input option provides reliability and peace of mind, as water pumping can continue during prolonged cloudy weather. The quiet operation and low noise levels of solar pumps also make them acceptable in residential and environmentally sensitive areas.


Protection is another cornerstone of the Kewo design. The inverters include comprehensive safeguards against overvoltage, undervoltage, overload, short circuit, overheating, dry-pumping, and phase loss. Additionally, they feature IP65-rated enclosures for outdoor installation, protecting against dust and water splashes. The built-in soft-start function reduces mechanical stress and water hammer damage, extending the lifespan of the pump. Furthermore, the inverters automatically detect insufficient water in wells via sensor inputs or sensorless dry-running detection, shutting down the pump to prevent damag

The Hybrid Solar Pump Inverter SN2200 represents a significant advancement in renewable energy water pumping technology, combining solar power generation with grid or battery backup to ensure reliable operation regardless of weather conditions. This report provides a detailed examination of the SN2200's specifications, operational principles, protection mechanisms, and typical applications, highlighting its role as a robust and efficient solution for modern irrigation and water supply systems.

Agricultural Irrigation: Supplying water for crop fields, drip irrigation, and greenhouse systems.
Livestock Watering: Providing water for cattle, sheep, and poultry in remote pastures.
Domestic Water Supply: Powering borehole or surface pumps for homes and small communities.
Desertification Control & Ecological Restoration: Used in forestry watering and sand-fixing projects.
Fountains and Aquaculture: Circulating water in ornamental fountains or fish farm

Case Study: ABB in Action
A notable example of ABB technology is a large-scale solar irrigation project in the Middle East. ABB supplied multiple solar pump inverters ranging from 75 kW to 132 kW to drive submersible pumps in a desert valley. The system was designed to deliver up to 2,000 cubic meters of water per day for date palm farms. Despite ambient temperatures exceeding 45°C, the inverters' robust thermal design and IP65 protection ensured reliable operation. The installation eliminated the previous diesel fuel usage of 150,000 liters per year, cutting carbon emissions by over 400 tons annually and reducing operating costs by 80

Wide Input Voltage Range: They accept a broad DC input voltage range, accommodating various PV array configurations (e.g., 12V to 250V or higher, depending on the model). This flexibility simplifies system design and allows for future expansion.
Robust MPPT Algorithm: The advanced MPPT algorithms are capable of tracking fast changes in irradiance, ensuring high efficiency (up to 98%) across a wide operating range. Some models feature multipoint MPPT, allowing connection of two different PV arrays (e.g., different orientations) without derating.
Built-in Pump Protection: The inverter monitors motor current, voltage, and frequency to protect against dry running, overcurrent, overload, and short circuits. This extends the pump's operational life and minimizes downtime.
IP65 Enclosure: Many ABB solar pump inverters feature a high ingress protection rating (IP65) as standard, making them dust-tight and protected against water jets. This enables outdoor installation without the need for a separate electrical cabinet, reducing installation costs.
User-Friendly Interface: A clear LCD display provides real-time data on input voltage, current, output frequency, and cumulative energy production. The parameter settings can be easily adjusted via the keypad, and the unit is configured for solar pumping applications out of the box.
Communication Options: ABB offers optional fieldbus modules (e.g., Modbus RTU, Profibus) for remote monitoring and control. This allows users to track system performance, adjust parameters, and receive alarms from a central control room or via a mobile app, depending on the platform.
Environmental Durability: Printed circuit boards are coated with a protective layer to resist moisture and corrosion, enabling reliable operation in tropical or coastal climates. The operating temperature range is typically extended to -10°C to +50°C, with derating at higher altitude
