At the core of the INVT solar pump inverter is maximum power point tracking (MPPT). Because solar panels have a non-linear voltage-current characteristic, the inverter continuously adjusts its operating point to extract the maximum available power from the PV array under varying irradiance and temperature conditions. The INVT manual specifies a high-precision MPPT algorithm with an efficiency typically above 99%. This ensures that even on cloudy or partially shaded days, the pump receives the maximum possible energy. The inverter supports a wide DC input voltage range, often from 200 V to 750 V or higher depending on the model, allowing flexible configuration of solar panels in series. This wide range also enables the system to start pumping early in the morning and continue until late afternoon, maximizing daily water output.
Hybrid Source Management and Transfer Logic
A key highlight of the SN2200 is its hybrid control logic. The inverter continuously monitors the solar array output. When the available solar power exceeds the pump’s minimum start threshold (typically 20% of rated power), the inverter runs the pump using solar energy only. If solar power drops below this threshold or becomes unavailable, the inverter seamlessly transitions to the backup source, either the grid or a diesel generator. This transfer is performed automatically using an internal relay or external contactor, and the changeover time is typically less than 100 milliseconds to avoid disrupting the pump operation. In configurations where both grid and generator are connected, a priority setting allows the user to choose which backup source engages first. The hybrid source management also supports a "mixed mode," where solar power is used as the primary source and the grid supplies any deficit, ensuring the pump always operates at a programmed frequency or power level if sufficient backup capacity is availabl
Introduction and System Overview
The hybrid solar pump inverter SN2200 is a dedicated power conversion unit designed to drive three-phase AC water pumps using solar PV energy, while also supporting hybrid inputs from the grid or a diesel generator. The "SN" series is engineered for small-to-medium scale agricultural irrigation, livestock watering, and rural water supply applications. The SN2200 model specifically provides a maximum output power of 2.2 kW, making it suitable for pump motors rated at 2.2 kW or below, depending on the operating conditions and pump type. Its "hybrid" designation means the inverter can automatically switch between solar power, utility grid, If you cherished this article and you simply would like to get more info concerning Newpro uninterruptible power Supply please visit the web-site. and generator sources to ensure uninterrupted pump operation even during low solar irradiance or nighttim
Regional variations within Thailand also affect pricing. In Bangkok and major cities, intense competition among suppliers tends to reduce prices, while remote provinces in Isaan or the North may see prices increase by 10–20% due to shipping and installation travel costs. Moreover, seasonal demand peaks during the dry season (December to April) can lead to temporary price surges, whereas purchasing during the rainy season may yield discounts or promotional bundles.
Market prices are also subject to volatile factors such as raw material costs, especially semiconductors and copper, which have experienced global supply chain disruptions. The Thai solar market has benefited from government incentives, including tax reductions and investment promotion from the Board of Investment (BOI), which can indirectly lower inverter prices. However, the lack of a mandatory certification for solar pump inverters has led to an influx of low-cost, lower-quality products. These can be found online for as little as 4,000 Baht for a 1 HP unit, but they often lack proper MPPT efficiency, fail to handle Thailand's high ambient temperatures, and have short lifespans. Conversely, premium authorized distributors offer after-sales services that justify their higher price tags.
Primary Technical Specifications
The SN2200 hybrid solar pump inverter operates with a wide DC input voltage range to accommodate different solar panel arrays. Typically, the input voltage range is from 200 V to 500 V DC, with a maximum open-circuit voltage (Voc) of around 550 V DC. This wide range allows the system designer to configure between 8 and 12 high-voltage solar panels in series, depending on panel specifications. The inverter incorporates a smart Maximum Power Point Tracking (MPPT) algorithm that continuously adjusts the operating point to extract the maximum available power from the photovoltaic array, achieving a peak MPPT efficiency of over 99%. The overall system efficiency, including the DC-to-AC conversion stage, is generally rated above 97% for solar-only operatio
To understand the pricing, one must first recognize that solar pump inverters are not off-the-shelf consumer electronics. They are engineered for specific power ratings, typically ranging from 0.75 kW (1 HP) for small household gardens to 110 kW or more for large-scale agricultural irrigation. Consequently, the initial price is heavily dictated by kilowatt capacity. As a general benchmark in the Thai market, a 1 HP inverter for a standard 0.75 kW pump may cost between 6,000 and 15,000 Thai Baht. Moving up to 3 HP (2.2 kW), prices typically range from 15,000 to 35,000 Baht, while 5 HP (3.7 kW) units commonly fall between 25,000 and 60,000 Baht. For heavy-duty systems such as 10 HP (7.5 kW), the price escalates to roughly 60,000–150,000 Baht, and large-scale inverters above 20 kW can exceed 300,000 Baht. These figures are indicative and fluctuate based on exchange rates, import duties, and local distributor margins.
