SG320 Series 690V Solar Pump Inverter
– Solar/AC Hybrid Powered VFD for Water Pumping
SG320 series is a high-performance solar pump inverter designed for solar-powered water pumping systems. It accepts DC input directly from solar panels and optionally switches to AC input (690V) when solar power is insufficient, ensuring continuous water supply day and night. This hybrid design eliminates the need for batteries or diesel generators, offering a clean, cost-effective solution for irrigation, livestock watering, and remote household water supply.

Advantages of solar pumps systems
Why SG320?
Most solar pump systems rely solely on solar power. When clouds pass or night falls, water stops. Diesel backup is expensive and noisy.
SG320 changes this. It accepts both solar DC and 690V AC input, switching automatically. Day and night. Sunny or cloudy. Water keeps flowing.
What Makes SG320 Different
| Feature | What It Means for You |
| Solar + AC hybrid input | No battery bank needed. Use solar first, switch to grid/gen automatically. |
| MPPT built-in | Extracts maximum power from panels even under clouds or morning/evening low light. |
| Dry-run protection | Pump stops when well is dry. No burnout, no replacement cost. |
| Sleep & wake-up | Auto shutdown at low sunlight. Auto restart when sun returns. |
| Tank level control | Stops pump when tank is full. Restarts when water drops. No overflow. |
| Remote monitoring | RS485 Modbus. Check pump status from your phone or computer. |

Where Customers Use SG320
Farm irrigation – No diesel. No fuel cost. Pump when the sun shines, or from grid at night.
Livestock watering – Remote pastures with no power line? Solar alone works. Add AC for backup.
Desert well pumping – Deep wells, harsh conditions. SG320 handles both.
Mountain water supply – Unstable grid? Solar covers daytime. Grid picks up at night.
Simple to Set Up
Connect solar DC (or 690V AC) and pump, set motor parameters via keypad, choose priority mode. Pump runs automatically. No battery or complex programming needed.
Protection You Can Rely On
SG320 constantly monitors pump condition: auto-stop on dry run, overcurrent, overvoltage, undervoltage, or overheat. Auto-restart when normal. Faults shown on LED keypad.
