When the light goes out in a house or apartment, not only does the connection with civilization disappear, but the products in the refrigerator begin to deteriorate, especially in the summer, especially in the southern regions. Someone did not have a gas, but an electric stove, not to mention a computer, TV, electric kettle, etc. This was fully felt by those who lived in the 90s. On the territory of Russia and the CIS during that difficult period, here and there, there were regular interruptions in electricity, and it was not uncommon that entire city blocks were saved in the evenings only with wax candles.

And although the dashing 90s are behind, in some places even today there are sometimes interruptions in power supply. This problem, of course, is solved by using modern uninterruptible power supplies (UPS) or liquid fuel generators. But not every homeowner can afford a high-quality autonomous power supply for an apartment, not to mention a large private house. Let's look at the possibilities for offline ...

The life of a modern person is hard to imagine without electricity. In everyday life, many different electrical appliances and electronic devices are used that make life comfortable and allow solving various problems. At a picnic or on a camping trip, the question arises of where to get electricity in nature, because even far away from civilization, modern man cannot do without a number of electrical appliances and devices.

We will not give tips on how to get electricity from wood, fruits, natural materials, etc. - these methods will fit only as an experiment showing the presence of minimal potential. We are only interested in reliable and proven methods that will provide power to electrical appliances for the required period of time. If you need to use various gadgets in nature, photo, video and audio equipment ...

The issue of generating electricity by alternative methods is quite relevant in our time. One of the options for providing electricity to the house is the installation of a solar power station. This option can be used as an additional alternative source of electricity or as the main one, if there is a task of power supply at home in the absence of the ability to connect to electrical networks, for example, because of their remoteness.

The first stage in the implementation of this idea is the calculation of the future power plant. In this article, we give recommendations that will help to correctly calculate the required power of a future solar power station and correctly assess the possibility of implementing this idea, depending on various factors. First of all, it is necessary to determine what tasks a future power plant should fulfill ...

Let's look at an example of a sequence of steps to select a controller. First of all, through search engines, for example, Yandex and Google, I collect information on all charge controllers that online stores offer in the country. Of course, I draw attention to the proposals in my region. If prices including delivery in the home region are comparable to prices in other areas of the country, I take such suggestions into account. If they are "transcendental" - I do not consider at all.

In my situation, there were no such offers nearby and my choice was somewhat “facilitated”. I will not give examples of stores that have come into my view, so that, God forbid, not impose my subjective opinion, moreover, not provoke you to make a mistake if, suddenly, my choice is not correct.I will say only one thing. In any case, before placing an order you should have ...

One of the indispensable devices of the backup power supply system of your home is an inverter. This device is designed to convert direct current from batteries to alternating voltage of 220 V with a frequency of 50 Hz, that is, it provides similar power supply to electrical appliances in your home. Along the way, the inverter can solve additional problems. Such as, for example, load shedding during critical discharge of batteries. There are inverters that include a charge controller.

Please note that this device is required for backup power supply, as The main power is supplied by a network voltage of 220 V AC with a frequency of 50 Hz. Since backup power supply is necessary when the main power is turned off, it must provide the same parameters as the mains one. In the case of autonomous power supply ...

Let's do a classic calculation of the entire solar power supply system, including the solar battery. I want to warn you right away, in this calculation I did not pursue the goal of minimizing economic indicators (we will deal with this later), but only set the task to show the calculation procedure. Based on the list of devices that we listed, we can determine the main parameters of the inverter for our system.

Firstly, since the list of devices contains devices that include engines: an electric pump, a refrigerator, a washing machine, a vacuum cleaner, we can certainly and should talk about an inverter that has a sinusoidal voltage output rather than a quasi-sinusoid. Secondly, the input voltage of the inverter must correspond to the voltage chosen by us - 24V. As for power, its choice depends on how you agree to use your devices. If you find it necessary to simultaneously ...

Whether we confess to ourselves or not, this does not change the essence. Very often, when we begin to implement our serious, especially less serious plans, we neglect projects or calculations. This, as a rule, does not lead to the expected results, or the total time or material costs are not expected at all. Of course, everything must be considered. It is unlikely that anyone will disagree.

As for solar panels, the calculation of their power is simply necessary, since the slightest deviation in any direction leads to a change in material costs by an order of magnitude. There is one more indisputable benefit from the calculation procedure - a conscious, clear understanding of the operating procedure of the future solar power station is being formed. Only a person who has operated an autonomous power supply system in his house will fully understand what this means. And this understanding comes down to one thing ...

Connecting solar panels should not be difficult. There is nothing extraordinary in this procedure. But as I continue to get questions on the scheme of connecting solar panels, I decided to write this article and give illustrations to remove these issues once and for all.

From the physics of the school period, we know the concepts of series, parallel and series-parallel (or mixed) connections. There is nothing in solar panels that would bring their connection beyond the concepts of school physics. I understand perfectly well that people ask these questions not because they do not know what a serial or parallel connection is. They know. They are “scared” by a new subject of consideration - solar panels.So, I will say it again: there is nothing like this in solar panels. This is just the same component of solar modules., like all others, and therefore the wiring diagrams...
