11 11 \ Renewable Energy Solutions Renewable Energy Solutions Solar Products Smart and Bi-directional Solar Inverters, ON-grid and OFF-grid Jema Energy develops and manufactures Smart solar inverters to maximize PV plant performance and minimise operation and maintenance costs. High performance Protection The state-of-the-art 32-bit floating-point digital signal processor delivers the highest level of computation accuracy currently available on the market. The control panel contains a microprocessor specially designed for high performance solutions in complex control applications. Space Vector Modulation Technology The inverter incorporates a level II DC surge protector, through the integration of fuses per input, with independent measurement capability for module fault detection, as well as a ground fault detection system. Configuration of facilities Thanks to the control algorithms used, Space Vector Modulation (SVM) enables the inverters to offer support services to the grid. The inverters work in the four quadrants of active and reactive power. The main advantage of SVM is that the inverter has two independent control loops for active power P and reactive power Q. This makes it possible to work at night in STATCOM mode, i.e., to only offer reactive power, even if no active power is available. This algorithm also enables harmonic filtration up to the seventh harmonic. Jema s engineering team provides technical support to all customers. Customisation allows optimal configuration of the photovoltaic plant and takes into account external variables, such as grid codes (reactive management at rated power), environmental conditions (altitude) or DC panel configuration (MPPT optimisation and voltage tracking).

16 1000 Vdc IFX2 and IFX3 Series Jema photovoltaic inverters offer large advantages for your commercial and utility scale PV Plant. All inverters are bi-directional and can serve as dual use PV and battery chargers. Design and performance The independent and modular power columns enable optimum performance in the event of low irradiance or the failure of one column. Master/slave mode enables maximum efficiency in the event of low irradiance by concentrating all the energy in a single column. Capacity to manage reactive power. Anti-islanding with automatic disconnection. Design according to anti-seismic guidelines. Dual bi-directional inverter: battery charger capability. Indoor and outdoor systems.

17 17 \ Renewable Energy Solutions IFX2 and IFX3 Series IFX2 central photovoltaic inverters from 500 to 800 kw (1000 Vdc) IFX2B battery charger IFX3 photovoltaic inverter from 1050 to 1200 kw (1000 Vdc) IBX3 battery charger High temperature performance IFX inverters are designed to work at high temperatures without derating. All inverters ensure nominal power to an ambient temperature of 50 C, maximising performance in the event of extreme heat. The inverters are composed of columns or independent power units to optimise the thermal regulation system. Each column therefore has a separate ventilation system that can efficiently regulate the temperature of the critical system components. This design structure offers ventilation by levels by activating and deactivating the fans depending on the temperature. It is also able to reduce the consumption of auxiliary power and increase system redundancy.

18 IF Series Jema s IF series of solar inverters is the result of more than 60 years of experience in the design and manufacture of robust, reliable, safe and high performance industrial power systems. Single power block IF inverters are mainly used in small plants. It is possible to form microgrids or hybrid solution by joining several IFs. Also available in a transformerless version to connect it to the IFX models and offer a power solution in unusual sites.

Global Smart Grid Controller Interoperable communication system Electronic power inverters for generation and storage Electric vehicle integration (V2G & G2V) Total power flow control Maximisation of the renewable energy source Jema was recently chosen to be the lead designer in a multi-vendor Microgrid pilot project funded by the Spanish Government. The aim of the project was to create an interoperable microgrid based on the IEEE standard. It manages energy efficiently, optimises resources, and energy is distributed automatically and intelligently. Furthermore, it saves energy, increases reliability, reduces costs and optimises the generation infrastructure. It therefore seeks to provide greater grid efficiency and reliability and to improve the safety and quality of the power supply in accordance with the requirements of the digital age. This smart microgrid integrates different distributed renewable generators (micro wind turbine, PV inverter, fuel cells) and storage technologies (supercapacitors, flywheel, Li-ion battery).
