Overseas cotton farms need deep root watering to promote strong plant growth—AUSENIST’s YS620 Cotton Farm VFD (a frequency converter) delivers slow, deep irrigation, making it a top choice for cotton growers in the US, India, and Pakistan.

A US cotton farm in Texas with 300 hectares reported a 12% increase in boll production after switching to YS620: the Variable Speed Drive runs pumps at low speed for 4 hours/day, allowing water to seep 60cm deep into the soil (vs. 30cm with traditional pumps). This promotes deeper root growth, making plants more drought-resistant. The farm also saved 27% on electricity bills. “Our cotton plants are stronger now—they survived a 2-week drought this year,” said the farm owner.

As a China AC Drive manufacturer, AUSENIST designed the YS620 for hot, dry climates: it works at temperatures up to 65℃, critical for Texas summers. It also has a dust filter to prevent sand from entering the inverter, a common issue in dry regions. “We used to clean our old inverters weekly; now the YS620’s filter lasts a month,” added the owner. AUSENIST provides English technical support and fast spare parts delivery to the US, so downtime is minimal.

Overseas hemp growers need precise irrigation to maintain THC/CBD levels—AUSENIST’s YS620 Hemp Farm VFD (a Variable Frequency Drive) adjusts water flow based on growth stages, making it a top choice for hemp farms in Canada, Colorado (US), and Europe.

A Canadian hemp farm with 150 hectares reported consistent CBD levels (within 0.5%) after installing YS620: the frequency converter waters seedlings with 10L/plant/week, vegetative plants with 20L/plant/week, and flowering plants with 15L/plant/week. This precision avoids overwatering (which dilutes CBD) and underwatering (which reduces yield). The farm also saved 24% on electricity. “Our CBD levels are more consistent now—buyers pay a premium for that,” said the farm manager.

As a China inverter manufacturer, AUSENIST ensured the YS620 meets hemp industry standards: it’s compatible with nutrient delivery systems, so growers can add fertilizers via the irrigation system. It also has a data logging function to track water use, which is required for hemp certification in Canada. “The data log helped us pass our certification audit easily,” added the manager. AUSENIST provides 24/7 English support and a 2-year warranty, so the farm gets help when needed.

Overseas coffee plantations (especially shade-grown) need moderate irrigation to maintain bean flavor—AUSENIST’s YS620 Coffee Plantation VFD (a frequency converter) provides balanced water flow, making it a top choice for farms in Colombia, Ethiopia, and Guatemala.

A Colombian shade-grown coffee plantation with 180 hectares reported a 8% increase in bean quality after switching to YS620: the Variable Speed Drive adjusts pump speed to deliver 15L/tree/week, which matches the water retention of shade-grown soil. It also saves 26% energy vs. traditional pumps. “Our coffee beans have a richer flavor now—we’re selling to specialty roasters,” said the plantation owner.

As a China AC Drive manufacturer, AUSENIST optimized the YS620 for mountainous coffee regions: it has a voltage stabilization function, critical for areas with unstable power grids. It also supports remote monitoring via mobile app, so the owner can check water flow from anywhere. “I monitor the YS620 from Bogotá—no need to drive 4 hours to the plantation,” added the owner. AUSENIST provides Spanish-language manuals and local service in Medellín, so issues are resolved fast.

Overseas olive groves need drought-tolerant irrigation to produce high-quality oil—AUSENIST’s YS620 Olive Grove VFD (a Variable Frequency Drive) delivers controlled water stress, making it a top choice for olive farms in Italy, Spain, and Greece.

A Spanish olive grove with 250 hectares reported a 12% increase in oil quality (higher polyphenol content) after switching to YS620: the frequency converter limits water to 10L/tree/week during fruit ripening, which creates mild water stress (ideal for olive oil flavor). It also saves 30% energy vs. traditional pumps. “Our olive oil won a regional award this year—thanks to the YS620’s precise watering,” said the grove owner.

As a China inverter manufacturer, AUSENIST designed the YS620 for Mediterranean climates: it works at temperatures up to 45℃ and has a drought mode that further reduces water use during dry spells. It also has a low-maintenance design, so the owner doesn’t need to service it frequently. “We only check the YS620 once a month—its low-maintenance is a big plus,” added the owner. AUSENIST provides EU-certified documentation and fast spare parts delivery to Spain.

Overseas sugar cane farms need high-volume irrigation to support tall plants—AUSENIST’s YS620 Sugar Cane VFD (a frequency converter) delivers large water flow, making it a top choice for farms in Brazil, India, and Australia.

A Brazilian sugar cane farm with 500 hectares reported a 15% increase in sugar content after switching to YS620: the Variable Speed Drive runs pumps at high speed (50Hz) during the growing season to deliver 50L/plant/week, then reduces speed (30Hz) during ripening to concentrate sugar. It also saves 22% energy vs. fixed-speed pumps. “Our sugar content is higher now—we get a better price from the mill,” said the farm manager.

As a China AC Drive manufacturer, AUSENIST optimized the YS620 for large-scale sugar cane farms: it can control multiple pumps (up to 8) simultaneously, reducing the need for multiple inverters. It also has a fault alarm function that alerts the manager via SMS if a pump fails. “We used to find pump failures hours later; now we get an SMS instantly,” added the manager. AUSENIST provides Portuguese-language manuals and local service in São Paulo, Brazil.

Overseas vegetable greenhouses need seasonal irrigation adjustments—AUSENIST’s YS620 Vegetable Greenhouse VFD (a frequency converter) adapts to summer/winter needs, making it a top choice for growers in the Netherlands, Canada, and Japan.

A Dutch vegetable greenhouse growing tomatoes and peppers reported a 10% increase in yield after switching to YS620: the Variable Speed Drive increases water flow by 30% in summer (to combat heat) and reduces it by 20% in winter (to avoid overwatering). It also saves 25% energy vs. fixed-speed pumps. “Our vegetables grow faster now—we have 2 extra harvests a year,” said the greenhouse manager.

As a China inverter manufacturer, AUSENIST optimized the YS620 for greenhouse automation: it integrates with climate control systems to sync irrigation with temperature and humidity. It also has a self-cleaning filter to prevent clogging from mineral deposits. “We used to clean filters weekly; now the YS620 cleans itself,” added the manager. AUSENIST provides EU-certified documentation and 24/7 English support, so the greenhouse gets help fast.
