PV grid-connected inverter and independent inverter in the control of what is the difference
Photovoltaic grid-connected inverter is the assembly of the DC into AC power for the use of load, or do not use the load, the inverter after the AC power to the city power grid, when the electricity outage, the inverter will automatically
The independent inverter in the output voltage phase amplitude of the frequency control is initially set good. Independent inverter, you should refer to off-grid inverter, do not need to consider the grid situation.
PV grid-connected inverter in the grid before the inverter needs to determine the phase voltage phase frequency, the first phase-locked, in the grid and power generation.
The independent inverter in the output voltage phase amplitude of the frequency control is initially set good. Independent inverter, you should refer to off-grid inverter, do not need to consider the grid situation.
And you said that the independent inverter, said off-grid inverter it, this inverter can not access the mains, the components of the electricity through the off-grid inverter to the battery charge, the battery at night
