DC side control technology

1. Maximum power point tracking technology The efficiency of the photovoltaic power generation system is the product of the photovoltaic conversion efficiency of the solar panel, the maximum power point tracking (MPPT) efficiency and the inverter efficiency. Improving the efficiency of MPPT is also of great significance to the efficiency improvement and cost reduction of […]

Leakage current suppression technology and grid filter

1. Leakage current suppression technology Because it does not contain high-frequency or low-frequency transformers, non-isolated grid-connected inverters have the advantages of high conversion efficiency, small size, light weight and low cost. However, non-isolated inverters lead to electrical connections between photovoltaic panels and the large grid. Due to the parasitic capacitance of the solar panel to […]
