Abstract—Grid connected solar inverter converts the DC electrical power from solar PV panel into the AC power suitable for injection into the utility grid. This paper discusses various control modules used for the developed grid tied solar inverter.
I. INTRODUCTION Grid connected solar photovoltaic (PV) system is one of the distributed energy resource which converts DC power produced by solar PV into AC power in a form suitable for pumping into the grid. The main purpose of the grid connected solar PV system is to transfer maximum solar array energy into grid with unity power factor.
D. Current control In grid connected solar inverter, the output of the inverter must have higher value than the grid voltage. Since grid voltage is not under control, the only way to control the power fed to the grid is to control the current fed to the grid. Digital PI current controller is used for grid current control algorithm.
Control structures for grid-connected photovoltaic systems The DC–AC converters inject sinusoidal current into the grid controlling the power factor. Therefore, the inverter converts the DC power from the PV generator into AC power for grid injection. One important part of the system PV connected to the grid is its control.
Therefore, only active power is pumped into the grid. The grid tied solar inverter is implemented using simple basic control algorithms: Maximum Power Point Tracking (MPPT) control, DC voltage control, grid synchronization control and current controller. This paper discusses the above listed control blocks in detail.
This paper discusses various control modules used for the developed grid tied solar inverter. The developed grid tied solar inverter uses a boost converter to regulate the DC power from solar PV panels and converts the output of the boost converter into AC using a single phase DC to AC converter.

If it''s connected to the grid then the input and output share the grid frequency and the inverters cannot frequency shift to control the output of the pv inverters so the only way they can establish control eg zero export is to be able to disconnect the pv inverter and they wouldn''t be able to do that unless you have the pv inverter output going into the solark or eg4.
