Eastman EGP1800 24V Solar Off Grid PCU Price Specifications

Eastman self-sustaining PMW PCU has been manufactured by using world-class technology platform and process as an efficient solution for areas struggling with frequent power cuts. It can be used for domestic, industrial and other events. It provides clean energy for residential and industrial areas without any residual effect. It has a self-adjustable setting which provides superlative performance in all weather conditions. It has profound mixing of grid current with solar in case of solar energy insufficiency during cloudy days. It consists an inverter, solar charge controller, AC charger and remote control (optional).

Eastman Off-Grid PWM PCU is superb for installation in petrol pumps, gas stations, schools, commercial, and residential applications. How Does It Work : In Solar Off-grid PWM PCU, when the sun rays hit on the solar panel, it leads to the generation of DC power which converted usable AC power for the functioning of the connected appliances. The surplus DC power is secured in the battery in case of power cut. The solar charger controller which is inbuilt insure appropriate battery charging and restrain the reverse flow of current to the solar panel. PWM means Pulse Width Modulation which is used as one method of float charging. It sends out a series of short charging pulse to the battery- a very rapid “on-off” switch. The controller continually checks the condition of the battery.
