1.ÿ Structure ofÿ Photovoltaic Grid-Connected Inverter SG4KTL-S DescriptionA solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into autility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.ÿIt is acritical BOS?component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.Suitable for 50Hz/60Hz grid, could be used in Asia, Africa and Europe. Available for hand installation, no need for lifting machineryÿassistance.ÿÿ2.ÿ Main Features of the Photovoltaic Grid-Connected Inverter SG4KTL-S?
