Description:
Bi-grid inverter can not only convert the DC power into AC power,but also can invert the AC power to DC power.Bi-grid inverter mainly control the battery’s charging and discharging,at same time it is the core control equipment.Bi-grid inverter can apply in the grid ties power system which has the requirement of power storage function.The power storage system is for the the emerging load or important load charging.It can combine with the string inverter and then construct the separated PV power system.
Bi-grid inverter charged by batteries ,convert the DC power into AC power.Constructing the Grid at the basis of the AC general line.String grid inverter can automatically test the solar battery array with enough power or not.Testing the grid whether meet the need of grid power.When meeting the need can go into the grid power mode,feeding power to the AC general line.,then the work of starting the system was completed.When normally operating .Bi-grid inverter will test the power using of the load .The power feeding to the grid from string grid inverter firstly for the load charging.If there is rest power ,BI-grid inverter will convert it into DC power and charge the battery.If the power feeding to the grid is not enough for the load,Bi-grid inverter will convert the DC power supplied by battery into AC power and feed into the AC general line for the using of the load.
