On-grid solution(Rapid Shutdown): Convert the DC from solar panels into AC with the same voltage, frequency, and phase as the grid electricity,and transmit the power to the grid, According to the safety requirements, install PV rapid shutdown device between PV modules and inverter, which can quickly cut off the DC high voltage among modules, the high dc voltage between photovoltaic module and grid-connected inverter,In the vicinity of the inverter, it is necessary to install (internal/external) isolatior to quickly turn off the inverter. In order to ensure the safety and reliability of on-grid solution, a distribution box is required to meet the requirements of distribution systems.

On-grid solution(Micre Inverter): Convert the DC from solar panels into AC with the same voltage,frequency, and phase as the grid electricity,and transmit the power to the grid. Use micro-inverter to replace traditional string inverter, module-level MPPT, maximize the photovoltaic power generation efficiency of the system. At the same time, the low input DC voltage makes the system safer.
