Product Description
2.1 Product Description
hopeSun series three-phase string on-grid inverter is independent developed by Hopewind.
it's main function is converting DC current generated by PV arrays into AC current and feeding it
into the grid.
hopeSun 8KTL/10KTL/12KTL are 2-input string inverters. hopeSun 15KTL/17KTL are 3-input
string inverters. hopeSun 20KTL/22KTL/25KTL are 4-input string inverters. hopeSun
30KTL/33KTL are 6-input string inverters. These products only suit for 400VAC low-voltage
grid-connected scenarios, such as village-level photovoltaic power stations below 400KW or
industrial and commercial rooftop photovoltaic power stations.
2.1.1 Schematic Diagram
hopeSun 8KTL/10KTL/12KTL are connected to the inverter through 2 PV string inputs.
hopeSun 15KTL/17KTL are connected to the inverter through 3 PV string inputs. hopeSun
20KTL/22KTL/25KTL are connected through 4 PV string inputs In the inverter. hopeSun
30KTL/33KTL are connected to the inverter through 6 PV string inputs. There are 2 MPPT circuits
inside the inverter for MPPT tracking of the strings, and then the inverter circuit realizes DC
conversion to three-phase Alternating current as he schematic diagram below.
