Operation of electrical appliances and equipment is inextricably linked to the function of the local network. The equipment operates due to the continuous supply of energy and abruptly turns off when the current is cut off. Such phenomena can provoke a failure of the filling of the device used. This is caused not only by sudden blackouts, but also by sudden drops in voltage. In turn, an uninterruptible power supply for the home allows you to minimize such risks, fully controlling the energy supply of the equipment being serviced.
What parameters are important in choosing a UPS?
Before getting acquainted with the characteristics of a specific UPS model, you should determine what requirements they will have to meet. For example, you can focus on the time of support of the power supply mode, which averages 10-20 minutes. An even more reliable parameter for assessing the compliance of equipment with the goals will be the capacity of the uninterruptible power supply, which on average varies from 1500 to 2000 VA, although there are deviations from this range. Here it is important to take into account precisely the maximum power potential, which will have to cover the operating equipment. This can be one unit or several, but in both cases it is important to add 20% to the power consumed by the device in order to obtain the minimum potential that an uninterruptible power supply should have.
How to choose a model for the house?
Most likely, this should be a high-power unit that can simultaneously serve several consumers. If we are talking about a residential building, then it is likely that it uses a computer, climate control equipment, as well as kitchen appliances, etc. By adding the total capacity, you can get a value of more than 20,000 VA. In addition, with a higher probability in the list of equipment to be serviced there will be devices with a technical basis sensitive to energy drops. Therefore, it is important that the time for which the uninterruptible power supply for the house resumes energy supply is minimal. On average, this interval takes from 1 to 10 milliseconds, although units with two converters begin their function instantly. A worthy option for such needs can be equipment from the Power-Vision line in the PW3F40 modification. The disadvantage of this model is its large dimensions, but the power of 40,000 VA will make it possible to use almost all the equipment of a typical residential building.
The nuances of choosing a UPS for a summer residence
Obviously, the power requirements in this case are not so high, and the main direction of choice will be addressed to the possibilities of autonomous and independent operation. The fact is that during the absence of the owner in the country, it may be necessary to take into account the parameters of the network even without an emphasis on the energy supply of equipment. Smart Uninterruptible Power Supplies from the APC C1500 Series will help you cope with this task. These models do not differ in high power potentials, but are optimally suited for work in technical rooms, server rooms and in the country.
The user can also configure the function of the unit to self-service some devices taking into account external conditions. If necessary, Smart uninterruptible power supplies can be adjusted according to the operating settings via remote communication channels.
What equipment is suitable for the boiler?
In this case, the UPS will serve one consumer or, in extreme cases, a set of devices that form the heating infrastructure. One way or another, for such needs, a power of 2000 VA is usually enough. The protection of the power source itself is much more significant, especially when it comes to working in a single system with gas equipment. Also note the strength of the case. It should be metal and possibly small in size, although this depends on the area of the boiler room. What else should be an uninterruptible power supply for heating in a private house? It is desirable that the operator had the opportunity to continuously monitor the operating parameters of the equipment, including voltage, overload, battery charge, etc. And caution should be taken when choosing models with active cooling systems. In addition to such UPSs, some boilers have serious restrictions.
How much is an uninterruptible power supply for a home?
The range of prices in the segment is very large, which is understandable given the variety of equipment characteristics. So, entry-level models designed to serve one low-power consumer can cost about 10-15 thousand rubles. This is followed by a medium-sized and universal uninterruptible power supply, the price of which is in the range of 30-40 thousand. Such units are just suitable for servicing individual rooms with critical equipment, boiler rooms, cottages, etc.
The most expensive UPSs are a class of high-power multifunctional units designed to serve several consumers simultaneously. This is already an expensive uninterruptible power supply, the price of which is about 700-800 thousand. This equipment is also presented in the Power-Vision line.
Conclusion
At first glance, power supplies of this type seem to be very responsible, technologically sophisticated and even dangerous equipment. Of course, it is impossible to underestimate the tasks that such units perform. Moreover, the uninterruptible power supply for the home can interface with almost the entire electrical infrastructure. Therefore, we are talking not only about the responsibility of the energy supply function, but also about the safety of the house as a whole. Another thing is that manufacturers seek to maximize the ease of operation of the UPS, as well as expand the possibilities for programmable control. As a result, users of modern models spend a minimum of time setting up the equipment system, while at the same time getting reliable protection of all kinds of household appliances.
