2. It is known that specific fuel consumption of the diesel engine depends on the load. If the load of the diesel generator are, for example, asynchronous motors, starting current higher than the rated several times. From 3 to 7. After the starting mode with high currents power engine often work with 20-30% of the nominal power only. In this case, the diesel engine do not heats up to normal operating temperature. Unburned fuel, oil deposited inside and engine "coking". In addition, it gives increased fuel consumption Ideal for diesel – to work with constant load in the range of 70-80% of the nominal value ERGA'S HYBRID www.erga-genset.com

3. This idea was the basis for developing the hybrid plant of ERGA Need to say - there are two interpretations of hybrid plant term - - use in addition to diesel engine energy from the sun and wind - use ERGA hybrid plant as combination of using of energy from batteries and diesel engine in the optimal mode ERGA'S HYBRID www.erga-genset.com

4. Now we are talking more about the ERGA term, although the schema allows you to use all of the above types of energy ERGA'S HYBRID www.erga-genset.com

5. For extended of maintenance period are also used for more technical solutions: the increase in oil&fuel volume - increased crankcase and extended fuel tank oil, fuel, air filters with extended life can also be used oil cooled diesel engines (Deutz type) it is also possible to use Tesla battery - Tesla PowerWall Thus, overall system efficiency is achieved by working in a more favorable for diesel engines load mode and extending of maintenance time interval up to 1000 working hours There is the possibility of upgrading the already installed diesel gensets with battery system for hybrids and components for extending maintenance intervals.

6. For all applications, the battery is the Core of the Hybrid System Pb-acid batteries Limited number of cycles High ratio KWh/m 3 Large impact of the temperature in the capacity Competitive price No electronic system for managing the charge and discharge Ion-lithium batteries High number of cycles Low ratio KWh/m 3 Not-competitive price (until now) Free-maintenance Electronic system for managing charge and discharge must be included.

7. Lithium battery currently used in mobile phones and small devices Lithium battery used in electric cars Lithium battery developed for energy storage applications such back-up Characteristics: High price No good warranty conditions First units put in the market recently No mass production ERGA'S HYBRID – POWERWALL BATTERY www.erga-genset.com

8. ERGA'S HYBRID – POWERWALL BATTERY www.erga-genset.com Battery must include battery management system in order to avoid overcharged and overheated. A thermal regulation system also must be included. Overcharge and overheat no controlled must produce the cell rupture Battery is non emission device unlike Pb-acid battery which emits toxic and explosive gasses in normal working conditions

9. TESLA MOTORS It was born as an electric car manufacturer The presence of storage energy battery in the electric car as a main part of the car creates the need of improving current batteries. After the improvement of the batteries and charger systems for the electric cars, Tesla motors launched its batteries in 2015. ERGA'S HYBRID – POWERWALL BATTERY www.erga-genset.com

10. Tesla motors has designed a solution for energy storage in domestic framework Tesla motors has applied the know-how acquired developing electric batteries for its cars. The POWERWALL battery launch by Tesla Motors highlights for: Competitive price Mass production Number of cycles up to 10000 10 years of warranty Modularity ERGA'S HYBRID – POWERWALL BATTERY www.erga-genset.com

12. Without Genset: It can work as UPS or Back-Up System for power failure in the Grid It can work as a alternative energy source (charging battery from the Grid in cheapest tariffs periods and feeding energy to the loads in most expensive tariffs periods) With Genset: The battery reduces the working time of the genset, increasing the life time of the Genset The Genset increases the efficiency due to reach its optimal working point It can work as a alternative energy source (charging battery from the Grid in cheapest tariffs periods and feeding energy to the loads in most expensive tariffs periods) Renewable source may be included ERGA'S HYBRID – POWERWALL BATTERY www.erga-genset.com

15. ERGA'S HYBRID – POWERWALL BATTERY www.erga-genset.com Now the first battery TESLA started sales in the USA. For the European market TESLA company has identified key suppliers that need to meet certain requirements. TESLA delivered only batteries, but Europe partner should be a supplier of additional equipment, such as rectifiers and inverters We are in close contact with the TESLA company in Europe and with its partners since 2015 summer and will be ready to provide necessary solutions when POWERWALL sales will start in Europe

16. BENCHMARKING OTHER PRODUCTS www.erga-genset.com Company ERGA is a customer-oriented company Since we are developers and manufacturers at the same time, we would like to receive your specification, on the basis of the required for customer technical and economic conditions.
