The digits accentuated in bold type in the option code correspond to the selected option in the table. Option code Selection Steel - standard paint / steel - heavy salty paint / stainless steel - standard paint Iron / amorphous Hz / 50 Hz None C to +40 C m to 1,000 m None English and Japanese 4.1 Enclosure Version and Ambient Conditions The selection of the enclosure version depends on the geographical, meteorological and material ambient conditions at the mounting location. Enclosure Steel - standard paint Steel - heavy salty paint Stainless steel - standard paint Proximity to sea from 7,000 m 300 m to 7,000 m 0 m to 1,000 m Steel - Standard Paint The version "Steel - standard paint" denotes steel with a paint coating which is 60 μm thick. This option should be selected at distances of more than 7,000 m to the sea. Steel - Heavy Salty Paint With this version, the paint coating is 80 μm thick. This option is recommended at distances of the Transformer Compact Station to the sea between 300 m and 7,000 m, providing that there is no exposure to salt spray. Stainless Steel - Standard Paint The version "Stainless steel - standard paint" is the option with the highest corrosion resistance. This option is recommended at distances of the Transformer Compact Station to the sea between 0 m and 300 m. It is also advisable to select this option at distances between 300 m and 1,000 m if the Transformer Compact Station is exposed to salt spray at this location. 8 TCS-JP-TI-ASB-A1-en-11 Technical Information

9 SMA Solar Technology AG 4 Option Code 4.2 Transformer Core Material Iron Transformers with a conventional iron core are cheaper to buy than those with an amorphous core. However, they are subject to higher losses. These losses are particularly high in comparison to an amorphous core when the transformer is running at low load or in no-load operation. Amorphous The use of amorphous core material leads to much lower losses in no-load operation. This is the case when the transformer is operated at night without load. If the inverter supplies reactive power during the night, using amorphous core material will become more and more uneconomical, since short-circuit losses (load losses) are generally higher for amorphous cores than for iron cores. As a transformer with amorphous core must be operated at lower induction levels, a higher copper input is required, which in turn leads to higher copper losses. Therefore, the use of amorphous core material is economically viable for powerful transformers. These are mostly only operated at full load during the day and at low load during the night, thus resulting in lower copper losses. Depending on the transformer size, the higher cost of the amorphous core material (compared to the iron core) will be paid back within its service life, and thereafter will generate energy and monetary savings. Calculated over the service life of the transformer, this saving can equal a multiple of the capital expenditure. Payback Calculation by SMA Solar Technology AG SMA Solar Technology AG offers consultation on how to determine the best transformer core material option for your application.

10 4 Option Code SMA Solar Technology AG 4.4 Additional Product Features Tap Changer The transformer of the Transformer Compact Station is equipped with a tap changer. Thus, it is possible to adjust the high voltage produced by the transformer to the regional Japanese voltage level. Depending on the mounting location of the Transformer Compact Station, the voltage level may deviate from the normal 6,600 V. It is possible to set the following levels: 6,750 V 6,600 V (default setting) 6,450 V 6,300 V 6,150 V* *At the lowest voltage level (6,150 V), a power reduction of 2.5% must be set in the inverter. Transformer Protection The Transformer Compact Station is equipped with a contact thermometer with two trip contacts. One contact is for the inverter. This switches the inverter off as soon as the transformer has reached a temperature of 100 C. This prevents overheating of the transformer. A second, potential-free contact is available for miscellaneous applications. Warranty The warranty period is five years. The statutory warranty covers all functions of the Transformer Compact Station. Wear and tear is excluded. 10 TCS-JP-TI-ASB-A1-en-11 Technical Information
