The operation of the Maule Novem inverter is straightforward yet intelligent. Solar panels produce DC electricity; this is fed into the inverter. Inside, the MPPT controller adjusts the duty cycle to match the panel's maximum power point for the current irradiance and temperature. The inverter then converts this DC into AC using pulse-width modulation (PWM). The AC output frequency is controlled to regulate the pump speed. Under low sunlight, the inverter outputs a lower frequency to start the pump gradually and deliver a reduced flow rate. As sunlight increases, the frequency rises, increasing the pump speed and water output. This soft-start and variable-speed operation minimizes mechanical stress on the pump and prevents water hammer, a common issue in fixed-speed system
The inverter's DC input side consists of a sophisticated Maximum Power Point Tracking (MPPT) charge controller. The PV system voltage range for the SN2200 typically spans from 150V to 450V, with an optimal MPPT voltage window between 200V and 400V. This wide voltage window allows for flexible solar array configuration, accommodating both 36-cell and 60-cell modules in series. The maximum input current for the PV array is around 12A, while the absolute maximum open-circuit voltage reaches 450V. The high-precision MPPT algorithm ensures a tracking efficiency of over 99.5%, extracting the maximum available power from the panels under varying irradiance and temperature conditions. For instance, on a typical sunny day with 1000 W/m² irradiance, the system can harvest nearly all available solar energy to run the pump at full speed, with a conversion efficiency of more than 97%.
The power rating of 220VDC inverters typically ranges from 0.37 kW to 7.5 kW, although larger units up to 15 kW exist. This makes them suitable for pumping depths of 10 to 150 meters and flow rates of up to 80 m³/h, depending on the pump’s hydraulic curv
In practice, Schneider solar pump inverters are used in a variety of contexts. In agriculture, they power drip irrigation, pivot irrigation systems, and cattle watering. In rural communities, they provide clean water from boreholes for drinking and domestic use. They are also used in fish farming to aerate ponds and in mining operations for water supply. The inverters are available with features specifically for rural installations, such as operating without batteries—pumping directly from the solar array during daylight hours, or storing water in a tank instead. This reduces capital costs and maintenance, as batteries are often the weakest link in off-grid systems.
A notable feature of the Novem is its "zero pump trip" design, which allows the inverter to restart the pump automatically after a cloud passes, ensuring continuous water delivery. If you have any questions relating to wherever and how to use Newpro Power, you can get in touch with us at our own web-site. The unit is housed in an IP65-rated enclosure, making it dust-tight and protected against water jets, ideal for outdoor installation near boreholes or storage tanks. The Novem series supports both single-phase and three-phase pump motors, with an output frequency adjustable from 0 to 60 Hz. It also includes dry-running protection, overvoltage/undervoltage protection, and overcurrent protection, extending the pump's operational lif
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.
Pump Motor Type: Ensure the inverter output matches the motor’s rated voltage, current, and frequency (e.g., 380V or 220V AC). A three-phase pump is preferred for efficiency.
MPPT Voltage Window: The PV array’s Vmp must lie within the inverter’s MPPT range (usually 200–300V for a 220VDC unit). The Voc of the array must not exceed the inverter’s maximum input voltage.
Power Rating: The inverter’s maximum continuous output power should be 10–20% higher than the pump’s power consumption to handle starting surges.
Inverter Protection: Check for IP65 or higher ingress protection for outdoor installation. Lightning protection is important in remote areas.
Installation: Placement in a shaded, well-ventilated area is advisable, as high ambient temperatures reduce inverter lifespan. Use appropriate DC fuses, disconnects, and surge protectors. Ensure the PV array cable lengths are minimized to avoid voltage drop
