A weight current control strategy was presented to solve stability and control accuracy of grid-connected inverter with LCL filter by direct current control. The control scheme used inverter side current and grid side current as feedback signal. Current feedback factor could change system performance.It also analyzed the influence on control strategy by grid inductance. A 5kW LCL weighted current control simulation system was built in Matlab/Simulink to verify the correctness of the theory and the control strategy. The simulation results show that, the current weighted control had high stability margin and steady state accuracy, grid current total harmonic distortion rate was very low, the power factor was very high; in addition, increasing grid impedance did not affect the stability of the system,but current harmonic was further reduced, and the power factor was lower .
