6. Grid-connected inverter:
Grid-connected inverter with DC-DC and DC-AC two-level energy conversion structure. DC-DC converter link adjusts the operating point of PV array to track the maximum power point. The DC-AC inverter mainly makes the output current in phase with the grid voltage, and obtains the unit power factor.
The system panel is equipped with a number of test ports for measuring DC and AC related parameters. It can measure the DC-DC voltage and current changes and the voltage and current during DC-AC inversion process and the curve changes and waveform contrast.
7 power search function
In the process of automatic adjustment, will see the LOW lights flashing non-stop, the power from 0 as a starting point, the maximum power point to increase the output power, restart up to 6 times, and then enter the power lock state, bright.
The time required to perform a power search procedure of six levels is 10 minutes.
Wide voltage input (15-62VDC)
Secondary power transformer conversion
◆ high-frequency two-way grid, one-way and network functions
◆ High frequency direct modulation, AC half wave synthesis
