"TL" (Transformerless) Central Modular Inverters RADIUS Industrial Three-phase inverter The GEFRAN RADIUS Modular system offers modular PV inverter configurations which are also suitable for power ratings of over one megawatt. The possibility of choosing the single power modules according to the solar generator means multi-inverter systems can be created and specifically optimised for each MPPT, using solutions developed around the basic stand-alone modules. Since each inverter is operated independently, any losses in the event of one of the modules stopping are drastically reduced. Each application is engineered and built to customer specifications, bearing in mind their electrical requirements as well as their logistical and organisational needs. RADIUS Modular systems offer technical flexibility and thus facilitate the technical and economic optimisation of the entire PV plant. With the Modular solution, adding or removing individual power modules is also extremely quick and simple. The TL (TransformerLess) version is particularly suitable for multi-inverter plant configurations in which the inverters are joined via a parallel connection to the grid. The use of a single grid output transformer, instead of several dedicated transformers, results in an even more efficient and far more cost-effective plant. 24 RADIUS Catalogue www.radius-gefran.com

String inverters RADIUS Industrial Three-phase inverter Radius Industrial string inverters have power ratings of 10.2 kw up to 20 kw. The use of advanced technology and low-loss components, and the absence of a transformer, make it possible to achieve peak efficiency of 98%. The wide voltage range of up to 400-800 VDC responds to the need to reduce installation costs, as the reduced number of strings involves less DC cables. The double MPPT channel is an additional advantage that allows "independent" DC inputs to be used if the PV field has a "non-uniform structure" or features several strings with different orientations and inclinations; it also allows better monitoring of strings and fewer mismatching losses. Thanks to the potential of the multi-mppt tracking system, reduced energy production times due to partial shading are also cut to a minimum. Radius Industrial String Inverters combine the advantages of multi-mppt tracking with maximum efficiency. 28 RADIUS Catalogue www.radius-gefran.com

Plant accessories for Central Inverter "Smart" string box Accessories String box - Data Logger The RADIUS JBX-COM is a parallel string connection system that measures the current in each string to enable continuous monitoring of correct module operation and detection of any faults on defective strings. Faulty strings are immediately identified and located so that service technicians know which strings need repairing without touching the others. The surge arrestors are recommended when the inverter is installed more than 30 metres from the string box. The wide voltage range of up to 1000 VDC makes this unit compatible with all modules, including latest-generation cells. General Characteristics ÎÎString box for 8 and 16 strings.

RADIUS LOG PRO-PLUS Advanced plant monitoring system MONITORING Accessories String box - Data Logger Plant data can be remotely accessed and displayed at any time. PV plant monitoring is performed by simply logging-in to the web portal where the values of energy produced, the economic returns generated and even the reduction of CO 2 emissions are displayed in real-time. REPORTING Reports monitoring energy production can be stored, printed or e-mailed. In the event of stoppages, they can be used as "certified proof" of loss of production to claim insurance under the State incentive package. ALARM DIAGNOSTICS The data logger also acquires any alarm signals coming from the strings and inverter so that these can be detected remotely, reported to our service technicians (by fax, e-mail or SMS) and eliminated as soon as possible. AMBIENT MEASUREMENTS The data logger also measures "ambient" variables that could affect proper plant operation: ambient temperature, module temperature, radiation and wind speed. These data are measured by external sensors and sent to the control server which interfaces with a satellite weather-forecasting service, compares the data and reports any differences in messages sent by fax, e-mail or SMS. Plausibility checks are performed to eliminate any false alarms. 44 RADIUS Catalogue www.radius-gefran.com

RADIUS SOLAR SERVICE: Periodical maintenance Maintenance contract High-level efficiency can only be guaranteed by servicing the plant regularly and maintaining the conditions in place at the time of installation. The maintenance contract includes a yearly inspection or online check, on a date agreed upon in advance with the customer, to make sure that each single component is in perfect working order. Quality checks are performed once a year and include a general overhaul and replacement of any worn or critical parts to prevent the risk of future malfunctioning. Detailed records are kept of all work that is performed and any repairs are noted in the service report. RADIUS INDUSTRIAL Warranty Extension Contract The extended warranty gives you the chance to extend the manufacturer's warranty. This cover offers the best value for money, as it includes unlimited assistance, even after the end of the warranty period. All you have to do is call. The contract includes an emergency service following receipt of the written request for technical assistance. RADIUS Energy Non-Stop Contract GEFRAN agrees to assume full liability for any loss of energy production due to reduced or loss of RADIUS inverter efficiency. Should we be unable to provide the service within the term as specified in the contract, we will refund the entire incentive tariff for each hour for which the service is delayed after the first 72 hours (3 days). Periodical maintenance is always recommended, as this can help to prevent faults and thus avoid machine downtimes that result in energy production shortfalls.
