INVT SP100 Solar Water Pump Inverter for Mobile Irrigation Carts in Malaysia

I. Project Background

Malaysian tropical agriculture is primarily characterized by dispersed cash crop cultivation. While rainfall is abundant, allowing for potential reliance on precipitation without dedicated irrigation systems, farmers prefer not to install fixed irrigation systems. Using mobile equipment for irrigation during the annual dry winter season offers a highly flexible and economical method for fields located on hills and among groves. Concurrently, the region boasts rich solar resources (average annual sunlight exceeding 2000 hours), providing natural conditions for photovoltaic applications.

Leveraging its "Easy Installation, High Protection" features, INVT SP100 Solar Water Pump Inverter became the core component for upgrading the power system of mobile irrigation carts, aiding local agriculture in achieving flexible and efficient irrigation.

II. Customer Pain Points and Needs

A Malaysian agricultural service company faced multiple challenges with its mobile irrigation cart fleet:

1. Inverter Protection Performance: Irrigation carts are parked and operate outdoors, exposed to dusty, high-humidity environments. Conventional devices often have only IP20 ingress protection, necessitating higher-protection electrical cabinets. This demands more installation space on the cart, increases costs, and achieving IP66 protection is difficult, potentially leading to frequent failures during rainy seasons or field operations.

2. Low Voltage Operation: The maximum number of PV panels an irrigation cart can carry typically supports only around 200 volts, even under ample sunlight. This is insufficient to meet the voltage requirements of common 220V AC asynchronous water pumps.

Core Customer Needs: A PV power system requiring quick installation capability, adaptability to harsh field environments, while enabling low-cost, low-maintenance, and stable operation.

III.  INVT Solution

The vehicle-mounted irrigation solution centered on the SP100 Solar Water Pump Inverter offers the following advantages:

1 High Integration, Easy Installation: The SP100 integrates an internal switch and features standardized plug-in terminals, enabling fixation and wiring without specialized tools. Installation time per unit is approximately 5 minutes, facilitating rapid batch retrofitting.

2. High Protection Performance: With an IP66 protection rating, the SP100 is dust-tight, protected against powerful water jets, and resistant to corrosion. It directly suits the harsh operating conditions of mobile irrigation carts, including field dust and high humidity during rainy seasons, preventing failures due to environmental factors.

3. Wide Voltage Input: Through its built-in boost converter, the SP100 can drive 220V induction asynchronous pump motors with a PV input voltage starting from just 100V, significantly reducing the number of required PV panels.

During on-site implementation, the SP100 was directly embedded into the equipment compartment of the irrigation cart. The wiring and fixation process was simple and efficient. The device's housing has no exposed ports, making it fully suitable for dusty and humid field operation scenarios.

IV. Customer Benefits
1. Improved Deployment Efficiency: The easy installation feature of the SP100 significantly reduced setup complexity. The customer swiftly completed the manufacturing/retrofitting of 20 irrigation carts.

2. Enhanced Environmental Adaptability: The IP66 high protection rating allows the SP100 to operate normally amidst field dust and rain splash. Even during non-operational periods, parking location requirements are less stringent.

3. Reduced Operating Costs: Replacing diesel with solar power reduced the unit irrigation cost by 75%. Annual savings per device exceed MYR 32,000, with a payback period of ≤ 8 months.

V. Conclusion

The INVT SP100 Solar Water Pump Inverter, with its "Easy Installation, High Protection" product characteristics, precisely met the requirements of the Malaysian mobile irrigation cart scenario. It enabled the rapid deployment of clean power while ensuring stable operation in harsh environments. In the future, INVT will continue to enhance the scenario adaptability of its solar water equipment, providing more reliable low-carbon power solutions for global agricultural machinery.
