1.ÿ Structure of Solar Photovoltaic Grid-Connected Inverter SG6KTL-EC 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. It is a critical BOS?component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar inverters have specialfunctions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.ÿ2.ÿ Main Features of the Solar Photovoltaic Grid-Connected Inverter SG6KTL-EC? Flexible design due to dual MPPT tracking that is equipped to obtain full nominal power, 3-phase supply? High energy yield due to maximum efficiency up to 98.1%?competitive wholesale price. ? Low noise levels and internal consumption due to natural cooling? Integrated theft protection?AC Voltage Range:150V-550Vac? Access to Home WiFi system and enjoy cloud services via smart phones? Integrated power management function, easy to receive the adjustable command from grid? Extensive communication: RS-485, Ethernet, WLAN / WiFi, 4 digital inputs for ripple control receivers?
