Rooftop intelligent hybrid solar system is an innovative and next generation system which is unique combination of grid –tied and of-grid solar system.
Batteries are also connected with the load to minimize the dependency on grid supply.
This system provides you optimum output from the solar power plant, power backup during power shut downs & nights and reduces monthly electricity bill by exporting the excess units to the grid. Batteries can be charged in this system from both solar power and grid power, backup solution can be configured based upon the appliances used in the power failure time and hours of backup required. Once the batteries are fully charges the system automatically cut-off the power supply to make zero losses.
Let us understand the switching’s of intelligent hybrid solar system with the help of few scenarios.
Solar power generates the electricity from solar power or sun light and supplied to the load directly without importing any power from grid and batteries. Excess generated power can either be stored in the batteries or exported to the grid with the help of “Solar Net Metering“
When solar panel generates insufficient electricity from the solar power, excess required power will be imported from the grid. Batteries are remain untouched in this scenario.
When the grid power shut down during day time, solar panels generates the power and supplied to the load, but during cloudy days generated power is not sufficient then the system automatically draws the power from charged batteries and maintain uninterrupted power supply during power cuts.
During night time solar pv system will not generate any power , so excess required power is imported from the grid to supply the entire load and batteries are remain untouched because to utilize the power during power cuts in night time.
If grid power supply shut down during night time, then these charged batteries are used to supply the power to the load to provide uninterrupted power supply for 24 hours.
