Inverters SMA

High-tech inverters for private and industrial solar power plants

SMA Solar Technology

SMA has been a leading company in the solar energy sector for 35 years. This has been achieved thanks to the dedicated work of more than 3,000 specialists worldwide. 80% of patents in solar energy belong to SMA. Every product in the SMA lineup is the embodiment of advanced technology and German quality. Thanks to transformerless components, the efficiency of SMA inverters reaches 98.5%.

Thanks to the latest engineering developments, SMA devices can operate reliably under maximum load for many years. Each inverter is equipped with numerous safety systems that eliminate the risk of serious damage to your station’s equipment. A wide operating voltage range of 380 – 1000 V ensures longer daily operation. MPP tracking uses the latest protocol, eliminating the need to interrupt generation. The monitoring system is simple and efficient, available both from a computer and a smartphone.

The SMA inverter product line includes solutions for all capacities, from small household PV systems to industrial, high-power plants.

Inverters for Industrial Power Plants

Industrial solar power plants can be small, medium, or large-scale.

Such PV plants are divided into two types:

• with a central inverter
• with a decentralized system

SMA provides solutions for both system types.

Inverters for Private Power Plants

A home solar power plant is your key to energy independence. Such systems can be autonomous, supplying remote facilities with electricity, or grid-integrated.

For both options, SMA offers specific components:

• single-phase in-grid inverters
• three-phase in-grid systems
• storage modules for round-the-clock energy supply

Each system comes with a user-friendly and simple monitoring system.

SMA Service

Professional servicing of your photovoltaic system is essential for optimal performance and high productivity. If needed, we will provide you with fast and competent technical support and guarantee that your system remains profitable in the long run.

Warranty obligations are a priority for SMA. In the event of a warranty claim, SMA ensures fast replacement of components so that your PV plant resumes operation as quickly as possible.

EXTENDED WARRANTY FLEX – an extended manufacturer’s warranty for peace of mind about the future.

SMA Solar Inverters

Inverters, as devices that convert DC into AC, first appeared at the beginning of the last century. Today there are more than 150 variations, but they are generally divided into three classes – stand-alone, grid-tied, and hybrid. Choosing an inverter for solar panels depends on the features of each class, but selecting the right brand and manufacturer is equally important.

SMA manufactures multifunctional inverters that can be used in grid-tied, stand-alone, and backup power systems.

What are the differences in stand-alone inverters for solar panels?

The stand-alone type can work with any alternative energy sources, as well as traditional diesel generators and other devices that generate electricity.

As part of a PV system, a stand-alone inverter performs the following tasks:

• during daylight hours, converts DC from panels into AC (220 V);
• sends the required amount of generation to energy-consuming devices;
• any remaining generation is directed to charge the batteries;
• when generation drops at the end of the day, switches to supplying energy from the stored battery charge;
• if the batteries are fully discharged, switches to other sources (e.g., backup generators).

Task priorities are pre-programmed in the device’s control unit.

It is recommended to purchase a stand-alone SMA “Sunny Island” inverter for solar panels in Ukraine with at least a 20% power reserve.

Features of a grid-tied inverter for solar panels

The grid-tied type differs from the stand-alone type in that instead of sending excess energy to the batteries, it feeds it directly into the city or regional power grid.

Grid-tied inverters have four key advantages:

1. They eliminate the need for storage batteries, reducing initial installation costs.
2. They do not require excess capacity.
3. Using a bi-directional meter with the grid allows earning 3.1 times more than consumption costs, thanks to the “green tariff” rate of 5.35 UAH/kWh versus the purchase rate of just 1.69 UAH/kWh.
4. The SMA “Sunny Boy” grid-tied inverter is cheaper than the stand-alone type, as it does not require additional capacity.

Advantages of a hybrid inverter for solar panels

A hybrid inverter combines the advantages of both stand-alone and grid-tied models. Purchasing one allows the system to operate in any mode – fully autonomous, grid-connected, or a combination of both.

Its operating principle is as follows:

1. During the day, part of the energy powers appliances, while the rest is distributed between batteries and the grid (the owner sets the proportions).
2. At night, during bad weather, or long winter nights, the system draws energy from the batteries or the grid.

More About SMA Inverters

SMA is a leader in the production of inverters for solar power plants. One of the brand’s key innovations is using two paired and synchronized inverters – the stand-alone “Sunny Island” and the grid-tied “Sunny Boy,” creating hybrid systems with a wide power range of up to 300 kW.

Another advantage of such “twin inverters” is the ability to almost infinitely expand system capacity by adding any generating devices – solar and traditional generators, wind turbines, hydro systems, etc.

SMA inverters are available in single- and three-phase versions, with a standard warranty of 5 years (though in practice they have operated for up to 25 years). Electronics and connectors are designed to be fully compatible with equipment from all leading global manufacturers – from BMW and Volkswagen to Miele and Vaillant.

Main advantages of SMA inverters:

• maximum efficiency and energy distribution control;
• maximum flexibility in operation and mode switching;
• broad compatibility with devices of various types and manufacturers;
• high reliability;
• a wide set of service functions (including real-time monitoring via smartphone, tablet, or laptop).

SMA inverters also work perfectly with another product we offer – the new type of cadmium telluride thin-film panels from the American manufacturer First Solar.
