Model WK600 and WK600D Solar and Wind Power Inverters Overview A compact DC to AC inverter designed for solar and wind power systems. Converts single phase 220V input into stable three phase output at 220V or 380V. Offers selectable output power and current levels, wide output frequency range, and control modes suitable for motor drive and power conversion applications. Key benefits Flexible compatibility: Accepts single phase 220V input and provides three phase 220V or 380V output to match common generator and grid configurations. Improved conversion and control: Open loop vector control and V/F control modes allow responsive performance for motor and power conversion tasks. Compact and lightweight: Small footprint and 2 kg weight make installation easier in constrained spaces. Multiple output options: Choose from several output power and current ratings to match load requirements and minimize oversizing. Builtin auxiliary outputs and relay: 24V and 10V auxiliary outputs plus normally open and normally closed relay contacts simplify integration with external control and monitoring devices. Key specifications Models: WK600, WK600D Type: DC to AC inverters for solar and wind power Input voltage: Single phase 220V Output voltage: Three phase 220V or three phase 380V Output power options: 0.75 kW, 1.5 kW, 2.2 kW Output current options: 2.5 A, 3.7 A, 5 A Output frequency: 0 to 600 Hz Control mode: Open loop vector control SVC and V/F control Output type: triple phase Auxiliary outputs: 24V output, 10V output Relay output: Normally open and normally close Weight: 2 kg Size: 220 x 150 x 130 mm Additional label: Size Three phase 380V Color designation: 5hp 4kw What makes it practical Wide frequency range supports both standard power conversion and variable speed motor applications. Multiple current and power options let you match inverter capacity to panel or turbine output and downstream equipment. Auxiliary voltage outputs and relay contacts reduce the need for extra control hardware. Typical applications 1) Small solar farm or off grid array: Convert DC from solar charge systems into three phase AC for local loads or for feeding into a three phase distribution panel. 2) Wind turbine systems: Interface turbine DC output with three phase motors, pumps, or local distribution while providing variable frequency control for rotor or pump speed management. 3) Workshop and light industrial motor drives: Provide stable three phase supply and variable frequency control for pumps, fans, and small machine motors where single phase power is available. Installation notes Verify input is single phase 220V and select the required output voltage and power rating before installation. Ensure proper ventilation and secure mounting using the compact 220 x 150 x 130 mm enclosure. Use the provided auxiliary outputs and relay contacts to integrate start stop and monitoring circuits. This inverter series provides a flexible, compact solution for converting single phase 220V input into controlled three phase output for solar, wind, and general power conversion needs without adding unnecessary complexity.
