FAQ

1.    How do I decide which system is right for me ?

For protection from long outages, include a generator or solar panels in your Must solar system. Shorter outages can be handled by a battery-only system.

2.    Where my system will be installed ?

Must solar systems are usually wall-mounted near a home's main electrical (circuit breaker) panel.

3. How do I install my system ?

A must solar backup inverter is connected to a home electric system , we will supply detailed installation manual and videos for our customers .

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 inverter and a solar inverter?
Instability, the wind speed and the equipment itself will directly affect the generator rotation, so the voltage and current fluctuations, frequency instability, in short, is the power quality is poor) Therefore, through the inverter after the first rectification inverter to improve the quality of power
Q:Is the grid side of the grid and the inverter?
Grid-type system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load + power grid (both in parallel).
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
When the power grid failure or disturbance caused by the power supply and network voltage drop, in the voltage drop range, the power group can be uninterrupted through the inverter and network operation.
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: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: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: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: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.
