From a control perspective, the GD20-015G-4 uses advanced vector control algorithms to provide high starting torque and stable speed regulation. The inverter is also equipped with a built-in PID controller that can regulate pressure, flow rate, or water level when used with appropriate sensors. The unit is designed for simple keypad programming, with an LCD/LED display that shows system status, output frequency, current, voltage, and fault codes. Digital and analog I/O terminals are provided for external control, remote start/stop, and feedback from transducers, while an RS485 communication port supports Modbus protocol for integration with SCADA systems or smart remote monitorin
Installation and Maintenance
The inverter is housed in a rugged IP20 enclosure (with optional IP54 upgrade for outdoor use) and can be mounted on a wall or inside a control cabinet. The operating temperature range is typically from -10°C to +50°C, with derating above 40°C. For solar installations, the PV array’s open-circuit voltage must be kept within the inverter’s DC input limits, and the pump motor’s rated voltage and current must be matched to the inverter output ratings. Installation is straightforward, and the keypad offers a guide for setting the motor parameters, control mode (V/F or vector), and PID reference. Routine maintenance is minimal, consisting of periodic cleaning of the cooling fan and heatsink, checking for loose terminals, and verifying that the internal capacitors remain within specified toleranc
Introduction
The GD20-015G-4 is a purpose-built solar pumping inverter designed to convert variable power from photovoltaic (PV) arrays or a conventional single-phase AC supply into a controlled three-phase AC output that drives a standard water pump motor. This particular model is rated at 15 kW with a nominal output current of 32 A and is configured to operate with a single-phase AC 220 V input while delivering a three-phase AC 380 V output. This makes the GD20-015G-4 an extremely versatile solution for agricultural irrigation, livestock watering, and rural water supply where both solar energy and a single-phase grid may be available. In this report, we examine the technical specifications, key features, operational benefits, and typical applications of this inverter, highlighting why it represents a robust and cost-effective choice for modern solar pumping system
The term “solar pump inverter” might sound complex, but its function is straightforward. In a typical solar pumping system, sunlight strikes PV panels, producing DC electricity. Most conventional water pumps, particularly those used in agriculture and residential water supply, operate on AC power. The inverter bridges this gap by converting DC to AC with the appropriate voltage and frequency. What makes a solar pump inverter unique compared to a standard inverter is its ability to handle the variable and intermittent nature of solar energy. Since sunlight intensity changes throughout the day, the inverter must continuously adjust its output to match the available solar power, ensuring the pump runs as efficiently as possible without being damaged by voltage fluctuations.
The benefits of using solar pump inverters are numerous. They make solar water pumping both economically and environmentally feasible. By eliminating the need for diesel fuel or grid electricity, they drastically reduce operational costs. They are clean and renewable, aligning with global sustainability goals. They also require minimal maintenance, as there are no moving parts in the inverter itself, and the overall system has a lifespan of 20 years or more. Furthermore, they enable water pumping in remote, off-grid locations where extending power lines would be prohibitively expensive. For farmers, this means reliable irrigation even in dry, sunny regions where it is needed most. For communities, it provides a sustainable source of drinking water without the recurring fuel expense.
The final chapters cover preventive maintenance and technical specifications. The maintenance guide is straightforward: inspect the device monthly, clean the fan and heatsink, and check all cable terminations. It also emphasizes avoiding the use of high-pressure water for cleaning, as the IP rating may not be sufficient. The technical specification tables list input voltage range, output power, efficiency, operating temperature, and enclosure dimensions. Many manuals also include a de-rating curve, which is critical for installations at high altitude or high ambient temperature. This information ensures that the selected inverter is correctly sized for the local environment.
In conclusion, the “solar inverter pump ราคา” is highly variable and dependent on multiple factors such as pump capacity, system quality, installation requirements, and available subsidies. While prices have fallen over the years, they still represent a significant initial investment for many farmers and communities. However, when evaluating the true financial impact, the long-term savings on fuel and electricity, combined with environmental benefits and energy independence, make solar inverter pumps an increasingly attractive option. Buyers are advised to conduct thorough research, obtain multiple quotes, and consider the full system lifecycle cost rather than focusing solely on the purchase price.
