The new three-phase SolarMax 6MT2 inverter optimizes the yields of small PV power plants, while the MT3-SV significantly reduces the system cost for decentralized large-scale power plants.
Biel, May 28, 2013 – The successful range of SolarMax MT inverters the Swiss manufacturer Sputnik Engineering is extended with the three-phase 6MT2 inverter (6kW) offering the flexibility required to achieve ideal yields with small, individual solar power plants with the help of its symmetric dual-tracking concept. For decentralized solar power plants, SolarMax developed the new MT3-SV (18kW). With an increased output voltage, this device is capable of reducing the inverter-related plant costs by up to one third. Furthermore, the integrated multi-tracking concept allows for optimizing yields through the use of very small power units. Thus, the two SolarMax MT inverters offer both low plant costs and the highest possible yields for every PV system.
MT3-SV: large-scale plant – huge inverter power output
The requirements for PV power plants are increasing continuously. Given the discontinued subsidies, the profitability of plants is more important than ever before. With regard to large-scale PV power plants, important factors must be taken into consideration in order to optimize both the plant’s yield and thereby also the return. For example, this includes leveraging the installation area as efficiently as possible or taking into consideration different ambient conditions. Thanks to the integrated multi-tracking concept of the MT3-SV inverter, module row clearances can be shortened. At the same time uneven terrain structures or different irradiation conditions are compensated in an ideal manner. The AC current is transferred to the medium-voltage transformer with an increased output voltage of 3 x 480 Volts. This significantly reduces the costs of the inverter-related plant components, particularly of the AC cables. In addition, due to the high power density of the MT3-SV, a lower number of devices has be installed on site. This further helps to reduce the plant costs.
“Within the direct competition with conventional power plants, the costs of solar power plants must be reduced in order to remain a profitable investment in the future even without subsidies. That is why we have extended our MT portfolio with an inverter which perfectly meets the requirements of solar power plants and simultaneously contributes to the reduction of the total plant costs,” explains Olaf Geistlinger, Senior Product Manager for the SolarMax string inverters. “With the MT3-SV, solar farms will remain a secure investment in the future.”
6MT2: Stable even with small power plants
Small PV power plants are more and more frequently required to contribute to grid stability as well. The three-phase SolarMax 6MT2 inverter distributes the power output symmetrically to the three phases of the power grid. This prevents load peaks or drops from having too strong an influence on the mains voltage. The 6MT2 works with two symmetric trackers and input currents of 9 amperes in each case. The yields of the respective module fields are optimized by independent operation, e. g. in the event of different roof orientations or different string lengths.
All SolarMax MT string inverters are Swiss quality products with power classes from 6 to 18kW and optionally two or three MPP trackers. The devices are used to implement both private domestic power plants and decentralized large-scale power plants with the utmost flexibility and profitability.
Both inverters will be presented at the Intersolar Europe 2013 in hall B4 / booth 110.
