Solar DC to AC Frequency Inverter for Water Pumps Model: WK600D (220V 4kW 16A 5HP) Also available: Solar 220V 0.75kW variant What it does Converts solar DC to stable 220V AC output suitable for driving AC water pumps. Frequency inverter (VFD) that improves DC to AC conversion rates, enabling more efficient use of solar power for pump operation. Key benefits Efficient power conversion: Maximizes usable AC power from a solar DC source, reducing energy loss during conversion. Motorready output: Delivers a controlled 220V AC supply for pumps up to 4kW (5HP) at 16A, with a smaller 0.75kW option for lowerpower needs. Simplifies solar pumping systems: Allows direct use of solargenerated DC to run standard AC water pumps without extensive additional equipment. Flexible application: Suitable for ongrid or offgrid solar installations where reliable pump operation is required. Important attributes Function: DC to AC frequency inverter (VFD) designed specifically for water pump drive. Compatibility: 220V system voltage; supports pumps up to 4kW 16A 5HP. Also available in a 220V 0.75kW variant. Performance: Focused on improving conversion efficiency between solar DC input and AC motor output to support steady pump operation. Model: WK600D represents the higherpower 4kW option; a 0.75kW Solar 220V option is available for smaller pumps. Practical use scenarios Agricultural irrigation: Power borehole or surface pumps directly from a solar array to irrigate fields without needing a separate AC grid connection. Rural water supply: Provide potable water or livestock water supply in remote locations using solar energy and standard AC pumps. Offgrid systems and seasonal pumping: Operate pool circulation, garden irrigation, or small industrial pumping where grid power is unavailable or intermittent. Installation and selection notes Choose the 4kW WK600D model for pumps up to 5HP and 16A; choose the 0.75kW variant for lowerpower pumps. Match inverter capacity to pump motor ratings to ensure proper performance and avoid overload. This product focuses on power conversion and frequency control for pump operation; confirm electrical compatibility with your solar array and pump motor before installation. Technical reminder 220V nominal output specification applies; power handling differs between the 0.75kW and 4kW WK600D options. Select the model that matches pump power and current requirements.
