4 KVA/ 48V Single phase MPPT based Off-Grid PCU

K-WIN Solar Power Conditioning unit (PCU) is an integrated system consisting of a solar charge controller, inverter and a Grid charger. It provides the facility to charge the battery bank through either a Solar or Grid/DG set. The PCU continuously monitors the state of battery voltage, solar power output and the load. Due to constant usage of power, if the battery voltage goes below a set level, the PCU will automatically transfer the load to the Grid/DG power and also charge simultaneously.

Most appliances like CFL, fans, motor based equipments like air conditioners and pump sets are designed to work on 50 Hz sine wave. Running such equipments on unregulated quasi sine wave-square wave based inverters poses a risk as regards performance and durability. K-Win DSP sine wave Static UPS and inverters are designed to provide stable 50 Hz sine wave irrespective of load and battery voltage, making them the most suitable for inductive, capacitive and non-resistive loads. Importantly, our inverters and UPS are designed to deliver instantaneous high current during start up, especially in case of air conditioners and refrigerators, with safety cut out when battery voltage goes lower than a specified point to avoid brownouts and burning of motors.
