Solar On Grid Inverters, Grid Tied Solar Inverter


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).

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:What are the methods of photovoltaic grid-connected inverter control
Inverter main circuit need to have a control circuit to achieve, generally have square wave and sine wave two control methods, square wave output inverter power supply circuit is simple, low cost, but low efficiency, harmonic components. Sine wave output is the development trend of the inverter, with the development of microelectronics technology, there are PWM function of the microprocessor has also come out, so the sine wave output inverter technology has matured.
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.
The grid inverter is a current source, the output voltage is basically the grid voltage, may be slightly raised.
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
Have a low pressure through the function set, low pressure through the scope of the project requirements, grid and network requirements and the actual situation of the design), low voltage grid to pass the voltage range is less than the medium pressure, parameter settings are not sensitive and complex.
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 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
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:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
Widely used in air conditioning, home theater, electric wheel, power tools, sewing machines, DVD, VCD, computer, TV, washing machine, range hood, refrigerator, video recorders, massage, fan, lighting and so on.
Q:Photovoltaic grid-connected inverter without DC emc how will happen
by means of energy converters can be converted into electrical energy. The process of converting light energy directly into electrical energy is precisely the response to photovoltaic effects. Without the need for any other mechanical parts, the energy in
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: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
