PV on-grid inverter

PV grid-connected power generation system consists of PV modules, grid-connected inverters, metering devices and power distribution systems. The PV module converts solar energy into DC power. The DC power is converted into AC sinusoidal energy of the same frequency and in phase with the grid through the grid-connected inverter. The DC power is supplied to the local load and the rest to the grid.

PV on-grid inverter

● Use the United States TI DSP chip control

● High conversion efficiency

● Advanced Maximum Power Point Tracking (MPPT)

● MPPT efficiency> 99%

● Wide voltage input range

● Disturbance detection technology to achieve anti-islanding control

● Perfect protection function, the system reliability is higher

● pure sine wave output, automatic synchronization and network, the current harmonic content of small, non-polluting power grid, no impact

● equipped with RS485 / RS232, Ethernet, GPRS (optional) interface, remote data acquisition and monitoring.
