Q:What are the methods of photovoltaic grid-connected inverter control
Sine wave output inverter control integrated circuits, sine wave output of the inverter, the control circuit can be used microprocessor control, such as INTEL company produced 80C196MC, Motorola produced MP16 and MI-CROCHIP company PIC16C73 and so on, these single-chip microcomputer has a multi-channel PWM generator,
Q:Grid-connected inverter is generally divided into photovoltaic power generation grid-connected inverter, wind power grid-connected inverter, power equipment and grid-connected inverter and other power generation equipment power generation inverter.
Grid-connected inverter is generally used with large-scale photovoltaic power plant system, a lot of parallel PV string is connected to the same set of inverter DC input, the general power of the use of three-phase IGBT power module, power
Q:Is the PV inverter a current source or a voltage source?
The inverter is mainly composed of a switching element such as a transistor, and turns the DC input into an AC output by repeatedly turning ON-OFF the switching element in a regular manner.
Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
In addition to the function of converting DC current into alternating current, the inverter also has the maximum output tracking function (MPPT), overvoltage protection, short circuit protection, island protection, overheat protection, overload protection and DC grounding
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Hybrid inverter is not a clear concept, but now both energy storage dual-grid inverter does have the ability to receive control system,
Q:PV grid-connected inverter and independent inverter in the control of what is the difference
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.
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Off-grid inverter is equivalent to their own to establish an independent small power grid, mainly to control their own voltage, is a voltage source.
Q:The function of photovoltaic grid - connected inverter
By dc / dc conversion to increase or decrease the input voltage, adjust its output to achieve maximum efficiency.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
Which depends on the grid inverter in the absence of the grid there is no independent operation of the function of the general grid inverter is the current type, only responsible for the power to the grid, the voltage is maintained by the grid,
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
Group is the use of a number of grid-connected inverter and grid-connected AC power grid, the advantage is the loss of small, low cost of the cable (because the PV cable is more expensive), eliminating the cost of the convergence box, and multiple
