·         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: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:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
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
Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
In addition to the function of converting DC current into alternating current, the inverter also has the maximum output tracking function (MPPT), overvoltage protection, short circuit protection, island protection, overheat protection, overload protection and DC grounding
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: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:What is the PV inverter starting voltage
sine wave becomes narrower and the voltage width in the center of the sine wave is widened and the switching element is always operated in a direction at a certain frequency in a half cycle, A pulse wave train (pseudo sine wave). Then let the pulse wave form a sine wave through a simple filter
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: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:The function of photovoltaic grid - connected inverter
After some additional voltage buffering, the left side of the bridge is usually 18 ~ 20khz switching frequency, the dc voltage is converted to ac voltage.
Q:Is the grid side of the grid and the inverter?
Off-grid system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load;
