Batteries
Rechargeable batteries are an indispensable element of autonomous and backup supply. The proper selection of their number and capacity largely depends on efficiency and reliability of the entire system. Batteries on 6 and 12V are the most widespread. If the voltage exceeds 12V batteries are connected in series so that the sum of the rated voltage corresponds to the required nominal voltage of the system. Similar (sequential) blocks may be connected in parallel if power storage of one unit is enough for normal operation.
Types of batteries used in power supply systems
1. Usual lead-acid low-maintenance batteries. Under good conditions and proper selection of their number their service life is 5-6 years.
2. AGM batteries (electrolyte absorbed into glass fiber). Lifetime under optimal conditions is 10-12 years.
3. Gel batteries (GEL). The service life is about the same or slightly larger than the AGM - 10-15 years.
Certainly, AGM and GEL batteries are more suitable for uninterruptible power supply systems, but their cost is usually several times higher than that of conventional lead-acid with liquid electrolyte. The most important requirement when choosing batteries is not to put them less than the recommended amount, as any listed batteries are sensitive to overcharging, which can significantly reduce their life term.
Requirements for the use of batteries
When using batteries should remember that their capacity decreases with decreasing temperature. And this decrease is quite significant. Usually at 0°C, the capacity of AGM batteries is 2 times lower than the nominal and further lowering the temperature of their usable capacity is also reduced.
The negative effect has also high temperature in the room where batteries are located. To avoid reducing the service term of the battery, the room temperature should not be above 25°C.

Industrial wind turbines
According to a report by the World Wind Energy Association (WWEA), annual power output of all wind power turbines installed worldwide by the end of 2013 is 318TVt that exceeds current electricity consumption of the United Kingdom - the sixth largest economy in the world.
Wind energy is an industry with significant growth and investment attractiveness, which makes it very competitive area for investment.
In today's Ukraine to invest money in wind energy is the most profitable for industrial facilities as state electricity tariffs for them is higher than for the population and, consequently, the payback period of the equipment is much lower.
According to the common classification for industrial wind installations UNOSAT wind turbines of 100 kW.
the Implementation of such projects often looks like this: the company uses electricity from the network, but does not pay for it or even gets the money, as it sells the electricity network that is produced by industrial wind turbines on "green tariff". A huge plus of such systems is that you do not need to use batteries, respectively, the system cost is greatly reduced.
Of course, the sale of electricity on a green tariff requires permits. But we should not blame our state; registration of permits in our country is easier and faster than, for example, in the UK or Italy.
WINDER Company being a member of the World Wind Energy Association, working with a number of European and American manufacturers of wind turbines and supplies components for wind turbines of average power. We can offer a fairly wide range of industrial wind turbines.
In today's conditions particularly advantageous is the use of renovated wind turbines. The large number of such machines in the European market due to the rapid development of wind energy, and in this regard, - the replacement of industrial wind turbines, which have served 5-15 years, by more powerful wind turbines. In Europe, there is an acute shortage of free sites with good conditions of wind speed. As a result, each year on the market is released wind turbines that have served just 20-60% of the resource. Taking into account that the prices of such wind turbines are 5-10 times lower than for the new ones, this option turns to be very attractive investment option for investors and Ukrainian companies with significant energy usage.

For the assessment of investment attractiveness and profitability of the installation of industrial wind turbine data are used watermonitoring. That is, directly at the place where it is planned to install a wind turbine, installed support for veterinerary with special equipment.
These wind-monitoring data allows calculating the monthly production of the wind turbine and the payback period. If financing of the project will attract foreign investment, wind-monitoring data is a prerequisite for starting of the work.

We know firsthand how important is high-quality electronics in work of reserve system. In its early days, our company faced with unscrupulous suppliers of inverters. Their overall performance was so low that a large part of the energy generated by wind turbine went just to maintain the inverter. This problem is particularly acute for the inverter with capacity of more than 10 kW.
Stand-alone inverters for wind turbines and solar panels
Inverters that we mainly use for high power systems have been developed in 2009-2010 by engineers of the WEL Company for Winder Company. Currently we offer four basic models, each of which has several modifications: 10 kVA, 20 kVA, 30 kVA, 50 kVA. Possible modifications of the input voltage: 240 or 360 volts DC. Output of three-phase (380V) or single-phase (220V). Optional inverters can be equipped with automatic (ATS).
In our company you can order as making the inverter to order and pick up the inverter from those which are represented in stock. Winder Company imported to Ukraine network and stand-alone inverters of many manufacturers, including German inverters SMA and Steca, USA ABB Power One and Tripp Lite.

Network inverters for wind turbines and solar panels
Network inverters are used in a system without batteries. Inverters of this type are commonly used for systems for "green tariff". In such systems electricity that is produced by wind turbine or solar panels are sold in a network of special higher rate (which is subsidized by the state). There are also inverters that provide power loads taking energy from the wind turbine part or solar panels, and the missing part is consumed from a network or diesel generator.
For network systems we offer the world's leading inverter manufacturers: SMA, ABB Power-One, Siemens, Danfoss, Steca. Winder Company also supplies inverters on order.

This is just a small part of the network and stand-alone inverters offered by the company. During selecting the components for power system based on wind turbine or solar panels we calculate the necessary power of the inverter based on the peak power and energy consumers’ power.
Controllers for wind turbines
The charge controller is designed to control the charge and discharge modes of batteries and ensures maximum efficiency and durability of all elements of the system, protecting it from overloads and short circuits.
The charge controller for wind turbine usually is included in the basic configuration of the wind turbine. Most of the wind turbines manufacturers are developing controllers individually for their wind turbine. In 90% of cases the wind turbine controllers are effectively cope with their tasks. If for any reason you are not satisfied with your wind turbine controller, Winder Company is ready to offer you universal programmable controllers of Ukrainian and Danish production. We also have available universal controllers for wind turbine power of 5 kW to 50 kW, with electronically controlled gondola designed for wind turbines Winder.
Controllers for solar panels
Controllers for solar cells are selected basing on the rated voltage and the total maximum current of panels. Moreover, the rated current of the controller must be 10-20% greater than the maximum current of solar panels. That is, if the total current is such as of 17A, optimally you should use the controller of 20A.
