MPPT Solar Pump Inverter Features: 1. MPPT efficiency exceeds 99%. 2. Drives all 1/3-phase AC pumps and PMSMs in the solar pumping system. 3. VOC solar panel tracking can be set manually or automatically with MPPT. 4. Both solar DC and grid AC power inputs are normal. 5. Dry run (no sensor required) and full tank protection. 6. Short circuit, overload, overcurrent, etc. motor output. 7. PQ (power/flow) performance curve enables calculation of pump flow output. 8. Ambient operating temperature: -10 to 50°C. 9. Inverter power range: 220V, 0.75kW to 110kW. 380V/480V, 0.75kW to 250kW.

Electric cargo ships equipped with ZK300 series high-performance engineering frequency converters have been in operation for several days. Their adoption of new straight-wing propulsion technology and a diesel-electric hybrid power system marks a new stage in shipping: "green, efficient, and intelligent."
