SUN 3/6K-SG04hybrid 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 3/6K-SG04. 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.

 

It equipped with RS485/CAN port for battery communication.

Q:Installation and maintenance of photovoltaic grid - connected inverter
, any failure that affects the safety performance of the inverter must be immediately removed before turning on the inverter again.
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
Self-use, do you mean off-grid system? Or else? Europe and Sweden side of the grid project electricity situation is also self-use? If not for their own use or spontaneous use is not used up, sent to other places electricity, you need a transformer?
Q:After the PV inverter, how to achieve the same period before the network?
It can automatically detect the generator and the grid frequency and voltage, in the frequency, voltage, phase are in line with the requirements of the grid to set the time before the release of the closing signal, so that it can be safely and securely connected.
Q:Photovoltaic grid-connected inverter without DC emc how will happen
light is obtained by the electrons of the semiconductor device, thus generating electrical energy. This energy conversion of light energy into energy, that is, solar cells. Solar cells, like transistors, are made of semiconductors. Its main material is silicon, and there are some other alloys. High-purity silicon used in the manufacture of solar cells is subject to special purification. Solar cells as long as the sun or light exposure,
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:Photovoltaic grid-connected inverter problem
But Baidu Encyclopedia clearly pointed out: the zero line is the secondary side of the transformer leads the neutral point of the line, and the phase line constitutes a circuit for power supply equipment.
Q:The function of photovoltaic grid - connected inverter
In general, single-phase h-bridge is a common configuration of dc / ac-level, but can also be used in three-phase and other configurations.
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:How the output voltage of the PV inverter and the grid-connected voltage are determined
Inverter is the DC power (battery, battery) into alternating current (usually 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. 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.
