3 Hybrid & Off-Grid Power Solutions The rapidly decreasing costs of renewables and battery storage have made hybrid power systems more affordable than diesel-based generation in most places around the world. About Us METKA IPS results from the combination of resources and expertise of METKA and International Power Supply (IPS), building on the strong technical expertise of IPS in the R&D and precision manufacturing of power electronics and energy conversion technologies, backed by the project execution capability and know-how of METKA, as a leading international EPC contractor, in addition to its robust financial resources. Through this joining of forces, METKA IPS is well positioned to meet the challenges of the rapidly growing hybrid and off grid power market, serving the needs of customers around the world with affordable and efficient solutions suitable for a wide range of applications, such as: telecoms, mini-grid, industrial, etc. Utilizing state of the art technology, an innovative R&D approach, and a flexible configuration architecture, METKA IPS is able to deliver affordable, clean power to non-electrified regions or unreliable grid locations in any part of the world. Hybrid energy systems support power grids that combine one or more sources of power generation (sun, wind, diesel generators and the grid) with battery storage to deliver a consistent level of electricity and/or store unused energy in a battery or future use. 3

4 EXERON Technology The EXERON range of off-grid power systems, developed and manufactured by International Power Supply (IPS), fulfils all the necessary requirements for effective energy management, communication and modularity, creating an optimal solution for off-grid locations. EXERON technology can offer power independence for areas with limited access to the grid or bad grid connection, whilst providing significant cost savings. This award winning technology features stringent modular design, easy-to-maintain hot plug technology, advanced battery management as well as the increased availability thanks to excellent system redundancy. How it works Uninterrupted output power through intelligent control of various energy sources: PV, wind, diesel genset and grid (if available). Battery banks are used to store energy for later use at night time, for peak shaving during day time or to provide resilient energy to the load during grid outages.

10 Which X system configuration do I need? I don t have power at all. EXERON is designed to generate, store and provide reliable power for remote and rural areas. The system can be installed indoors or outdoors. PV, wind and diesel gensets can be used as input power sources and a battery can be used for energy storage. The output can be 1 or 3 phase. I have power only from a diesel generator. EXERON can significantly reduce the OPEX costs related to the diesel genset (DG) operation. Depending on the system design, X can even completely replace the DG. It can be installed indoors or outdoors. It intelligently controls the operation of the DG, which minimizes the DG running hours, maximizes the maintenance period and reduces the overall operation costs (OPEX) up to 98%. PV is used as input power source and a battery is used for energy storage. The output can be 1 or 3 phase. I have a grid connection, but unreliable with regular power outages. EXERON is perfectly suited to locations with limited or bad grid power. It can secure continuous uninterruptible power and operates also as an UPS system. Installing PV strings at the input (and eventually a diesel genset as an emergency source) + battery storage, the required backup time can be reached so that the loads are always supplied with pure sine wave power from the EXERON. I have a reliable grid connection. If there is a reliable grid connection, EXERON is primarily used to generate power from PV or wind and to use the grid only when there is not enough solar or wind power, or when the battery is empty. 10

11 EXERON achieves a significant electricity bill reduction; a back-up power capacity for the unusual case of power outage; the best protection for the connected loads is guaranteed since the X output is galvanically isolated and supplies pure sine wave voltage. For countries in which different and dynamic electricity tariffs are available, then the EXERON can preferably use the grid when it is cheap to supply the load and/or charge the battery and use the battery later when the tariff price gets expensive. The system can be installed indoors or outdoors. I have already an On-Grid power system, but no more incentives If there is already an installed On-Grid system in operation and the back-feeding tariff is cancelled or uneconomical, the existing PV system can be connected to the EXERON to maximize energy self-consumption. Battery storage is installed to secure the power supply at night time. I have an unreliable grid connection with broad voltage and frequency fluctuations that damage my appliances. Due to the double energy conversion and the galvanic isolation between input and output, the EXERON's inverter output generates a perfect sine wave voltage, 50Hz or 60Hz with accuracy of +/ %. X guarantees the maximum possible protection for the connected loads against over-voltage, below-the-nominal voltage, frequency fluctuations and any other disturbances. Whatever comes to the input, it cannot be transferred to the X's output. 11
