·         Q. What is an UPS and What it is for ?

An uninterruptible power supply (UPS) is a device that allows your computer or telephone switch or critical equipement to keep running for at least a short time or longer time when the primary power source is lost. It also provides protection from power surges, spikes, brownouts, interference and other unwanted problems on the supported equipment.

·         Q. How long the UPS to run when power goes?

This can take 3 paths.
1.You can pick a UPS that is rated for pretty much the full VA you need so it will be running at 100% of capability and will thus last 'n' minutes.
2.You can pick a UPS that is rated at a much higher VA value than you really need so, for example, is running at 50% of capability and will thus last for longer than the UPS from option 1.
3You can use extra external battery packs to run for longer. If charging capability allows, the more and the bigger batteries you take with, the longer time UPS runs. 
or using a generator after about 6 hours, it will be more cost-effective, with a short runtime UPS to bridge the generator start-up gap.

Q:Is the PV inverter a current source or a voltage source?
According to the waveform modulation method can be divided into square wave inverter, stepped wave inverter, sine wave inverter and modular three-phase inverter.
Q:The working principle of photovoltaic grid - connected inverter
Inverter will be converted into alternating current DC, if the DC voltage is low, then through the AC transformer boost, that is, the standard AC voltage and frequency. For large-capacity inverter, because the DC bus voltage is high, AC output generally does not require transformer boost that can reach 220V, in the small and medium capacity of the inverter, because the DC voltage is low, such as 12V, 24V, It is necessary to design a boost circuit.
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: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:How the output voltage of the PV inverter and the grid-connected voltage are determined
due to the higher penetration rate of the car to go out to work or travel can be connected with the inverter battery drive electrical and various tools work. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. And then a large number of power inverter power
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
, This method is simple to design, easy maintenance, but also for the power grid harmonics smaller, good power quality!
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
Part of the distributed grid-connected projects, the basic are "spontaneous use, the power of the Internet," these do not need to boost, because the extra power is actually consumed by the surrounding electricity users, do not boost to a Level power grid;
Q:What are the methods of photovoltaic grid-connected inverter control
Sine wave output inverter control integrated circuits, sine wave output of the inverter, the control circuit can be used microprocessor control, such as INTEL company produced 80C196MC, Motorola produced MP16 and MI-CROCHIP company PIC16C73 and so on, these single-chip microcomputer has a multi-channel PWM generator,
Q:PV grid-connected inverter can directly load it?
Grid-connected inverter is usually equipped with island protection function, can only receive the power grid, if the load directly, the output is disconnected.
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.
