Inverters

What is a solar inverter?

Solar inverters are the components of a solar installation that convert the direct current generated from the solar panels to alternating current for the use of the consumption and loads of a home or an industrial warehouse. In Tienda Solar you will find all kinds of inverters (off-grid invertersgrid connected inverters and hybrid inverters), of different voltages (12V-24V-48V), different brands (Victron, SMA, Huawei, Sungrow, GoodWee, etc...) and all at a very competitive price. For technical information on inverters go to the bottom of the page.

What is a solar inverter in detail?

As we have explained in the heading of this category, a solar inverter is in charge of transforming the direct current of the solar panels into alternating current for later use. The vast majority of the equipment used in the home and in the industries is supplied with alternating current with a given voltage and frequency (230V in single-phase and 50Hz in Spain) parameters that are not those given by the continuous part of the photovoltaic panels. The solar inverter is therefore in charge of carrying out the necessary transformations and adjustments so that our equipment can be powered by solar energy.

What are the types of solar inverters?

We can mainly find three types of solar inverters on the market:

 - Grid connection inverters: this type of inverter is used in those solar installations that have a     connection to the electrical grid and can be synchronized with its voltage (V) and frequency (Hz)     parameters.

 - Inverters for off-grid installation: as its name indicates, they are suitable for solar                 installations that do not have a connection to the electrical grid. This type of inverters is capable of operating under a "network" that it generates by itself with the optimal voltage (V) and frequency   parameters for use in conventional electrical appliances.

- Hybrid inverters: Hybrid inverters are usually used in systems that need to operate connected      to an electrical network and at the same time they can do so without it. They are usually used in   hybrid installations where the system can be connected to a network, to different types of     generators, or operate temporarily as an isolated system.

What to take into account when choosing a solar inverter?

There are many brands, models and types of solar inverters on the market. But what should be taken into account when choosing a solar inverter?

Installation type: Will we mount our inverter in a grid-connected, isolated or hybrid installation? Based on the previous description, we will have to choose if we need a grid connection inverter, isolated or hybrid.

Inverter power: According to the needs and configuration of our solar installation, we must choose the corresponding inverter power. The power of the inverter is usually stipulated in its description or name. It refers to the power in watts or kilowatts (or failing that VA according to the power factor) that the AC part of the inverter is capable of providing given a voltage and frequency and at a standard ambient temperature. Depending on the loads we want to feed, we must choose one power or another. It is important to note that the inverters also specify in their technical data sheet which is the power to be connected in the continuous part, that is, of solar panels. This power is given in Wp / kWp since the photovoltaic panels are expressed in peak power, the maximum power that the panel is capable of providing in certain circumstances of temperature and irradiation that are considered standard, although they are not very common.

That is why the power of panels is usually oversized with a DC / AC ratio that each inverter manufacturer describes in its technical data sheet. In general, when it comes to maximizing solar system generation, the power of solar panels at peak power is greater than the power of the inverter in Wac or VA.

Inverter voltage: In the case of the inverter voltage, we must understand what the solar installation (grid / off-grid / hybrid) should be and what loads and consumptions it will be connected to. In the case of isolated installations or that have battery storage, depending on each case it will be more suitable to use:

- 12V solar inverters: usually for small installations, of no more than 2000 W. A low voltage (12V) implies a greater wiring to reduce losses, so this voltage is usually used for installations that mount batteries with little storage capacity, i.e. small facilities.

- 24V solar inverters: usually for medium-sized installations, of no more than 5000W.

- 48V solar inverters: usually for medium and large size installations, up to 10000W. Although for very large installations it tends to go to higher voltages, the standard step ends in 48V, beyond that the solutions are already made to measure and with inverters that allow a varied range of voltages.

Maximum and output current of the inverter: It is important to know the maximum input current (DC) and output (AC) of the inverter in order to understand how the strings / module chains should be designed in the DC part and to understand what overcurrent protections they could be necessary in both the alternating and continuous part.

MPPT number (if applicable): The maximum power point tracking (MPPT) number, also known as the number of MPPT followers, refers to the number of solar panel string inputs that an inverter has in which it tracks maximum power point, that is, independently optimized. Each series or string is the union of photovoltaic plates with a given current (I of the modules in the chain) and a voltage given as the sum of the voltages of the panels connected in series (V). Therefore, a string will have a current and a voltage (V and I) that will correspond to one input of the inverter. The MPPT consists of a series of electronic components capable of constantly searching for the combination of voltage and current that provides the greatest possible power for each input. Since the production of the panels varies according to the radiation incident on them and the temperature, a greater number of inverter MPPT will ensure a higher performance of the panels of the entire solar installation. Furthermore, the solar panels can be mounted with different orientations or inclinations only in the event that each of these groups of modules is connected to a different MPPT tracker. Thus, for example, if we have a gabled roof where we want to mount solar panels on both, we will look for an inverter with 2 MPPT inputs. 

Inverter life and replacement: Solar inverters can have a life of more than 10 years without having any problem. Depending on the conditions of use of these and certain random parameters, life can be more or less longer than these 10 years. Typically, manufacturers of solar inverters usually give factory warranties of 2 to 10 years. However, these can be extended in periods of 5 or 10 additional years by acquiring so-called "warranty extensions" from manufacturers or distributors of solar material such as Tienda Solar. It is common in the industry for inverters to have a life of 10 years and in the financial and life approaches of solar installations, the replacement of solar inverters is usually assumed after 10 years. It is important to mention that this replacement is a reasonable hypothesis given the failure rate of these components and the accumulated experience in the sector over time.

What are the best brands of solar inverters?

There are a variety of brands on the market and it is true that sometimes it is difficult to choose which of them is the most suitable for our installation. Just as in the case of solar panels there is a classification of brands and manufacturers (the so-called Tier's published by Bloomberg) there is no such classification for solar inverters.

From Tienda Solar and given our experience in the sector (construction and operation of solar plants) we have selected a number of brands that offer good long-term performance and competitive prices.

We usually recommend brands like SMA, Victron, TBS, Studer, Solax, SAJ, Sununo, GoodWe, SUNGROW, Huawei, Fronius, Solaredge, Kaco and Ingeteam. Some of them are cheaper than others, but the catalog available on our website will ensure efficient and long-lasting operation of your solar installation.
