Q:Installation and maintenance of photovoltaic grid - connected inverter
photovoltaic systems Power generation system used in the cable must be connected firmly, good insulation and specifications appropriate.
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, how much light to send online to the number of online, simply do not want people to the grid does not like.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
The solar grid-connected inverter is not connected to the grid and can not be directly connected to the load to supply power to the load because there is no voltage.
Q:How the output voltage of the PV inverter and the grid-connected voltage are determined
DC voltage and AC side voltage does not matter, the general PV inverter AC output is 400V / N / PE. With no isolation transformer and output voltage does not matter, grid-connected inverter is the regulation of current, and network voltage depends on the grid voltage. And the grid before the inverter will detect the grid voltage, meet the conditions will be network.
Q:PV grid-connected inverter can directly load it?
TL5001 operating voltage range of 3.6 ~ 40V, its internal with an error amplifier, a regulator, oscillator, a dead zone control PWM generator, low voltage protection circuit and short circuit protection circuit
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 PV inverter starting voltage
sine wave becomes narrower and the voltage width in the center of the sine wave is widened and the switching element is always operated in a direction at a certain frequency in a half cycle, A pulse wave train (pseudo sine wave). Then let the pulse wave form a sine wave through a simple filter
Q:Photovoltaic grid-connected inverter problem
The first zero line is the AC output. Any AC output of the inverter will have zero line, whether it is isolated or non-isolated. Isolation is the safety of high voltage inverters and regulators. 50KW above the inverter almost with the transformer.
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:Generally a large grid-connected photovoltaic power plant will have several inverters
Inverter, a single failure, does not affect other operations, the impact on the grid is small, high reliability.
