Popularity is on the sun panel every year. The scope of gathering mashab, they can and will be intentional when equipping greenhouse complexes, private housing, housing fences, farms.

What is a solar inverter for?

In our holy city there are many systems that consume 220 V voltage. Connect the panels to generate permanent electricity with a voltage of 12 V, 24 V and a maximum voltage of 48 V. A suitable inverter, which may be used on a battery suitable for 220 V, is required.

Characteristics on design

The Samiyat inverter consists of a low-quality adapter (diode and current converter), varicap (work for a triode with a conductivity of over 4 microns), dinistori (osigure sensitivity) and planes.

Many modifications to the taqiva units are based on a fixed element - an unpredictable unit.In the case of DC lips being protected in case of damage to the electrical network, the electricity is not and spread to the battery (charged by the charger), the trace of the inverter and to the point of consumption to the energy in the electrical supply. Structural system in perfect protection including low voltage monitoring with the help of a microcontroller. That giving a command for svarzvane on zahranvaniyata in case on preksvane on zahranvaneto.

The presence of something on the transformer in the design is not required to be inserted, for some reason I am correct. But, in the presence of a tosi element, becoming possible and using the signal at the exit at super high quality.

The design on the system can include a fan, which is forced to function and is designed for quiet operation with some mode (in the available models).

It is possible to combine a few inverters in a three-phase unit with increased power and extended coverage from the task of designing for 380 V (three-phase network).

Modern solar inverters

Principle for action

First, a battery of action of a kato converter on a cell to an electrical current, a trace battery system secharging correctly with current and correctly voltage, maintaining a charge of it in a battery and through a connection to an inverter device, converting direct current into an exchanged current.

The inverter is a semiconductor type device, that is, a golden medium between the electrical conductivity on metalite and dielectric (some have a high rating on the tosi indicator, others do not conduct electricity). For yes, the energy has crawled into darkness, it has been perverted into battery.

Important characteristics

for yes, avoid the loss of energy, the efficiency of the tryabva and nadkhvarli nivoto from 90%; the average cost reached 94%, for the optimal model - up to 99%;
absolutely no radio interference;
condition: stabilized initial voltage (preference for trapezoidal type); minimum input voltage;
low harmonic index;
temperature range - kolkoto - wide, sensible - good (influencing the quality of the device);
susceptibility to stress;
protection against predovarvane and pregryavane;
minimizirane on ruin with a slip on tension (with a right move);
rated power and maximum current at the output and input;
medium efficiency efficiency - a coefficient that shows the usefulness when changing the cost of voltage;
range for determining the maximum possible voltage (point on the possible characteristics for power on the inverter between the solar panels);
Nothing to protect the code for exercising from outside access to water and solid objects.

Election to inverter

When choosing a suitable inverter for the solar panel, it is necessary to include all products for peak power and activity (nominal values in this case are not taken foreseen). In the simplest model, it is enough to calculate the current at the nominal value. The voltage from 12 V is interrupted by the current consumer's panel switch, the controller sends the signal to the inverter's switch, it's a voltage converter, it's still 220 V.

Mezhovi modifications

Tosi type inverter is based on a capacitive diode (varicapi) with a low-frequency modulator for variations. It is used on a mesh structure and is most suitable for solar panels with a topping shape.A lot from tyah imat conductance on-golyam from 40 microns, from lining in insulators, some functions through the controller on the charge. What is related to the inverter current converters, the frequency of the boost is 30 Hz.

predominance: compact, high size, acceptable speed on conversion from low consumption to energy.

The hybrid inverter can run all the time, some of it is connected in the middle, plus it has some additional functions: increasing the power by the time at the pre-production stage, continuing and working with the loss at 220 V, there is a problem with the measuring device. Some manufacturers, combining an inverter and a controller into a device, will convince the client that the technology of sugar converters is hybrid, contrary to the odds, these devices will be combined.

The peculiarity of the hybrid inverter is the ability to simultaneously receive the power supply from the mains and from the battery and have priority from the source with direct current, without neglecting the source from the constant storage of electricity. When determining the priority resource at the top of it, the fall is mainly on the goods, the electricity is taken from the secondary battery.

Independent inverters

Suitable for solar panels with different capacitances, adaptable and functioning with overvoltage current up to 4 A, equipped with three hoods.

predominanceA: You can install a varicap with low resistance, low conductivity, and the ability to regulate the frequency on the option. It is stable at high humidity, high-speed conversion, safe price is acceptable for the consumer.

The classification of the input is based on the output format: right-angled, sinusoidal and pseudo-sinusoidal signal.

Square Wave

Spored against the experts, theses of the device will be used for good for supplying energy to the body.

predominance: passing price, forest for use.
lack: without coverage, I’ll limit the voltage to the limit, the spectrum of the application is narrow (not suitable for all kinds of devices and daily devices, due to incompatibility).

Sinusoidal signal

Produce high-quality current with a correct sine wave, clean from electricity, and away from contact. Suitable for joining massive domakinsky uredi: refrigerators, boilers, climate control, pumps.

predominance: Protecting the housekinskite uredi from abuse.
Disadvantage: high price.

Pseudo-sinusoidal signal

Compromise with up-mountain options.

predominance: osigurevat functionirovanieto on vschki domakinski uredi and uredi, sa evtini.
lack: Not suitable for sensitive devices that cause confusion and noise.

Inverter connection

For yes, you will wire the inverter correctly, tryabva and you know the nuances:

choose a cable with a medium length (not pre-heated for a long time and not for a kas); how the cell is distant, it can be installed, provided that the cable from the source to the inverter is not overhanging three meters;
pay attention to the straight section on the cable (correspondence with the current force on the power on the device and the straight section);
osiguryavat soundly fastened to the cable, for yes, avoid a spark and subsequently a fire;
sometimes use sources on an inexorably protected, installed on a pre-existing break directly into the verigata on a permanently stored current;
pay attention to the format of the output signal to the voltage on the inverter, before using it in the system;
sieve: in terms of signal purity, it is necessary to avoid damage to the device, not all devices can work with a curved sinus form (gas and boilers, pumps with an unpredictable circulation period, connected to video and audio cameras - the accuracy is too high).

The principle of operation is simple and you can always use an inverter for a solar battery with your own power.

Panel se montirat on nai-illuminate often from a curve or stenat for a reward for efficient work. When mounting on a panel, it is important that all spazva desires straight ahead of the horizon, and yes, all the same, foreseeing the degree on the darkening of the zonate (fix me far from the object, which is szdavat syanka).
