Inverter for solar panels: types, scheme, purpose. Solar power station for home

A large number of people are interested in solar panels. In order to convert AC current in devices, inverters are used. Modern power plants differ in power, as well as in frequency. In this connection, certain requirements are put forward to inverters. In order to understand the issue in more detail, it is first of all to familiarize yourself with the device of the inverter.

Modification scheme

The inverter circuit includes an adapter, varicap, and an overlay. The adapter consists of diodes and a rectifier, which operates at a low frequency. The process of current transformation depends largely on the varicap. As a rule, it operates from triodes with a conductivity of at least 4 microns. Also, the inverter circuit includes dinistors, which are responsible for the sensitivity of the element.

Types of devices

Separate stand-alone and synchronous devices. A separate category includes multifunctional modifications. Depending on the type of output signal, there are meander and sinusoidal modifications. They differ not only in their parameters, but also in their design. In this regard, each type of device should be considered in more detail.

Features of autonomous inverters

Stand-alone inverters are suitable for solar cells of different capacities. Speaking about the parameters, it is important to note that they are able to work with an overload of no more than 4 A. Protection systems they have different series. Varicaps on the inverter for solar cells are often set low-resistance type, and their conductivity is low.

It is also worth noting that the standard model of this type is made on three plates. Thus, she rarely has conduction problems. If necessary, the frequency of the modifications can be adjusted. Modern devices are characterized by high conversion speed. They also work stably under conditions of high humidity. It is worth a high-quality inverter (market price) from 2500 rubles.

Synchronous devices

The network solar inverter is produced on the basis of capacitive varicaps. The modulator for the modifications is selected at a low frequency. These devices are more suitable for plate-type solar cells. It is also worth noting that many modifications have a conductivity of more than 40 microns. Insulators they use with lining. Some devices are connected via a charge controller. The limiting frequency of the modifications is approximately 50 Hz. If we talk about design features, it is important to note that the models are manufactured with triodes. Very rarely used adjustable rectifiers. The speed of the transformation in this case depends on the sensitivity of the varicap.

Multifunctional models

A multifunctional solar inverter is a device that is able to convert a current from several batteries of different power. Modern modifications are made on transitional varicaps. Rectifiers for the inverter for solar panels are installed with a frequency of 30 Hz.

If you believe the experts, then the model is more suitable to select from 2 kW. They have a rather high conversion speed and low energy consumption. If we consider devices on channel dinistors, then they are able to brag of good security. Also worth noting that they have compact dimensions.

Meander modifications

Meander units are suitable for solar cells of low power. First of all, it should be noted that the modifications work at a frequency of no more than 40 Hz. Protection systems for them are used in different classes. Comparators for the inverter for solar panels are installed with two filters. Some devices are capable of operating at 3A overloads. Rectifiers are often installed on inverters in strip type. They are not afraid of impulse oscillations and work stably at high humidity. Also worth noting is the reasonable price for inverters of this type.

Sinusoidal devices

Sinusoidal network inverter is manufactured with channel adapters. These devices are suitable for solar cells that are manufactured with open cell type photocells. If you believe the experts, then you should not prefer modifications to operational comparators. First of all, they have low throughput. Also worth noting that they quickly burn out because of the temperature increase. The output voltage of the inverter for solar panels is maintained at 10 V.

Solar power plants of a tower type

Tower batteries are great for large houses. The photocells they use are used for two diodes. In this case, the reflectors are installed in different sizes. If you believe the experts, then in the market there are many models with filters that work at a low frequency.

Also worth noting that this type of battery is very easy to install. Stands with them, as a rule, are made of stainless steel. The charge controller in the devices is applied to three contacts. Many modifications can boast of excellent performance. To connect systems, modulators with a bus are used.

Modifications of tray type

Tapel type devices are very rare in homes. First of all, it should be noted that the radiators for them are suitable only for the tubular type. The standard modification includes a contact receiver. Most batteries operate at a low frequency, and the output voltage level depends on the installed controller. Also worth noting that the market is represented by many modifications with collectors. Stands in the devices are made of stainless steel, and they are attached to the support plates. The nominal capacity of this battery is on average 2 kW.

Features of Models with Modules

Batteries with modules are characterized by stable operation. Devices are great for giving. Also worth noting that the market is represented by powerful modifications with dinistors. Reflectors have different sizes. They are installed on the racks, which are fixed on the plates. If you believe the experts' opinions, then this type of battery has a high conductivity factor. The operating frequency of the devices is at least 50 Hz. Many modifications are capable of operating from tubular radiators. Receivers are often installed on triggers.

Parabolic modifications

Parabolic batteries work with inverters of different frequency. Adapters are used to connect the modifications. Dinistors are often installed with an overlay. Many models have several reflectors. Receivers for devices are selected for three contacts.

The operating frequency of this type of batteries starts from 45 Hz. The conductivity coefficient is about 55%. Many modifications are distinguished by high output voltage. The allowed overload parameter for the equipment is 3 A. Protection systems for batteries are used in different classes.

Combined devices

Combined batteries have recently been in high demand. First of all, it should be noted that the modifications are capable of operating under different humidity conditions. Some of them are sold with two tubular radiators. In this case, the reflectors are of low sensitivity. If you believe the experts, modern modifications have excellent conductivity, and a low coefficient of voltage loss. At a frequency of 55 Hz, the battery is capable of producing about 3 A. Selectors in devices are of contact type. Modifications are made through the channel ports. Some of them are manufactured with integral receivers.

Rheostat devices

The rheostatic solar power station for the house works from contact adapters. The models have a low frequency, but a high stability of the input voltage is achieved. Emitters in this case are able to work at low resistance.

Some experts believe that these devices are most effective for small houses. It is also worth noting that modifications are made with receivers of an adjustable type. Their operating frequency is approximately 55 Hz. At the same time, the current load averages 5 A. At high humidity, the modification includes a protection system.

Vacuum modifications

The vacuum solar power station for the house has always been famous for its performance. However, to date, such models are expensive. These devices are made with channel adapters that connect via ports. If you believe the experts, many models are able to operate at a low frequency and at the same time produce high voltage.

The indicator of the permissible current load is 5A. The protection systems for batteries are of different classes. Reflectors are often used in a magnetic type, and they are mounted on plates. Converters use low sensitivity. If you believe the experts, you should not choose devices with broadband receivers. They are not able to work from the comparator and at the same time suffer from impulse noise.
