How to ensure backup power supply of a country house is better than a generator

Last spring in one of the electrical companies approached an elderly man from Voronezh and asked him to build his cottage inverter system. This desire arose after existing generator known firm would not start the next time power disconnection. The family were trapped in the dark on its own plot in the centre of Voronezh, as well as the front gate opened electrically, which at this point was de-energized.

Engineers have calculated and installed at this customer the power back up inverter type with capacity of 3 kVA with 4 batteries with a capacity of 200 Ah, which is sufficient to protect the most essential loads, including the gas boiler, fridge, 2 TV's, lights in 3 rooms, automatic gates.

This question bothers a lot of other people, which at the time I bought the generator. Proekspluatirovat it some time, they are looking for an alternative solution to the problem backup power supply without the noise and exhaust gas, without the hassle of having refueling, maintenance, construction of special spaces. They want backup power system was working in automatic mode without human presence to it instantly and is guaranteed to be included in the power outage. People want reassurance, peace and comfort. In the age of the iPhone and iPad they are looking for modern solutions to replace old backup power supply generator. So they choose inverter system with OutBack inverters (USA), won worldwide recognition for quality and reliability.





In the basic inverter system includes one or more OutBack inverters and maintenance-free special batteries with capacity of 200 Ah 230 Ah Gel technology or AGM with a lifespan of 10-12 years. One inverter can take power from 1.3 kVA to 7 kVA. Due to their parallel connection it is possible to create a system with a capacity of 70 kVA for single phase and up to 27 kVA for three-phase network. The number of batteries may also be different. It is determined by what time you need to provide the backup and what is an average hourly consumption at the facility. The inverter system can provide backup power from several hours to several days due to the energy stored in the batteries.

With the disappearance of the current in the power grid, the inverter automatically switches the power load to the batteries in such a short time that all devices continue to operate without shutting down.





During the period of the supply voltage built into the inverter of this five-step charger charges the batteries and keeps them fully charged. To charge batteries you can also use alternative sources of energy e.g. solar panels.
