Solar Power Conditioning Unit

GENERATION PROFILE

Single Phase PWM RangeSingle Phase PWM Range

PWM Range - Single Phase: 4KVA/96VIt is an integrated system consisting of a Solar Charge Controller, Inverter and a Grid charger. It has inbuilt intelligence to utilize the solar power on priority. Working Principle Solar PCU converts energy from solar panel as the first priority and incase the solar power can not support the load grid power is used to charge the battery and supply load.
