Product Description:

SUN 6K-SGhybrid inverter, is suitable for residential and light commercial use, maximizing self-consumption rate of solar energy and increasing your energy impendence.   During the day, the PV system generates electricity which will be provided to the loads initially. Then, the excess energy will charge the battery via SUN 6K-SG. Finally, the stored energy can be released when the loads require it. The battery can also be charged by the diesel generator to ensure uninterrupted supply in the event of grid blackout.

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 working principle of photovoltaic grid - connected inverter
Full-bridge inverter circuit to overcome the shortcomings of the push-pull circuit, the power transistor to adjust the output pulse width, the output AC voltage RMS that changes. Since the circuit has a freewheeling circuit, even if the inductive load, the output voltage waveform will not be distorted. The disadvantage of this circuit is that the upper and lower arms of the power transistor are not common, so you must use a special drive circuit or use isolated power supply. In addition, in order to prevent the upper and lower arm co-conduction, must be designed to turn off after the conduction circuit, that must be set dead time, the circuit structure is more complex.
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:In a photovoltaic grid-connected project, the role of the inverter is to convert the voltage into AC 220V or 380V for the grid, since the transformer will raise the voltage again
Connected to the grid is connected to which specific location ah? Transformer is to buy a separate, or buy inverter inside the type of transformer? For example, Sweden's 15KW and 30KW grid roof projects, the roof, for example, more remote to be transported to other electricity.
Q:What is the PV inverter starting voltage
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power. Generally consists of boost circuit and inverter bridge circuit. The boost circuit boosts the DC voltage of the solar cell to the DC voltage required for the inverter output control. The inverter bridge circuit converts the boosted DC voltage to the AC voltage of the common frequency. 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. Of course, it is not practical to simply output the inverter output waveforms from the on and off circuits
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
For photovoltaic power plants when the power system accidents or disturbances caused by photovoltaic power plant grid voltage drop, in a certain voltage drop range and time interval, the photovoltaic power plant can ensure that non-off-line continuous operation.
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid 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: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:What is the difference between a PV inverter and a solar inverter?
The main function of photovoltaic grid-connected inverter is to convert the DC power of the solar PV module into the same frequency as the sinusoidal AC power of the grid (the grid is generally AC power grid, DC can not be directly connected)
