Product Description:

Solar On Grid Inverters, Grid Tied Solar Inverter

Products

Solar On Grid Inverter controls the whole system. Solar Inverters converts the DC current  produced by the solar array into AC current, then the Solar On Grid Inverters transfers AC current to the grid, and adjusts the operation point in real-time according to the variation of sunshine to realize the maximum power point tracking (MPPT).


Success Stories

1           1


Technical Features

Adopting the dynamic VI MPPT method which has independent intellectual property; fast response and stable operation.A modified anti-islanding detection method can effectively shorten the detection time whilst keeping a high power quality, remove the obstacles to the grid, and suitable for a multi-inverter system.


Digital control with full automatic running, data storage and completely protective function.

Save the daily operating data automatically and consult the operating data for 8 years. It is convenient for statistics and analysis.

Dormancy function, save energy and reduce abrasion.

New design of anodized aluminum case; pretty appearance; perfect cooling and shielding.

Through optimization of the design, On Grid Inverters is adopted with free cooling instead of fans, and then the Solar Home will reduces the maintenance costs.

Light in weight, small in size, flexible installation.

Q:After the PV inverter, how to achieve the same period before the network?
When the voltage, frequency, phase does not meet the requirements, the automatic closing closing pulse.
Q:Installation and maintenance of photovoltaic grid - connected inverter
Before making an electrical connection, be sure to use the opaque material to cover or disconnect the PV panel. Exposure to sunlight, photovoltaic arrays will produce dangerous voltages. All installation operations must be done only by qualified technicians.
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:What are the methods of photovoltaic grid-connected inverter control
and can set the dead time between the upper and lower arms, the use of INTEL 80C196MC to achieve sine wave output circuit, 80C196MC to complete the sine wave signal, AC output voltage, to achieve regulation. Circuit output generally use LC circuit filter high frequency wave, get pure sine wave.
Q:Is the PV inverter a current source or a voltage source?
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power.
Q:Is the grid side of the grid and the inverter?
Off-grid system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load;
Q:The function of photovoltaic grid - connected inverter
Finally, a sinusoidal AC output for a grid-connected photovoltaic power generation system is generated by a low-pass filter.
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Offline generally need energy storage, not to send energy online. Power grid has no right to interfere.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
The use of a high-power grid-connected inverter into the grid, the need for line design is relatively simple, because the DC and AC lines are separated, the use of convergence box to summarize, DC bus and then into the grid inverter
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.
