FLX PRO 15 SMA SMA

FLX PRO 15 is a series of three-phase, transformerless solar inverters from the brand SMA. These inverters convert the direct current generated by solar panels into alternating current and transmit it to the grid with the parameters of the local network. They are designed for use in small and medium-sized households and are highly efficient, achieving a maximum efficiency of 98%.

The FLX PRO 15 inverter has a flexible design, thanks to the use of Maximum Power Point Tracking (MPPT) technology that allows for optimal output even in partial shade and efficient operation when solar panels are oriented east-west. The inverter is also easy to install, thanks to its newly designed wall mounting.

The user-friendly interface of the FLX PRO 15 inverter features a high-resolution, multi-pixel screen that can display information in all languages and characters. The inverter operates with minimal cooling, resulting in low noise levels.

The FLX PRO 15 inverter has a maximum PV input power per MPPT of 8KW and a maximum DC voltage of 1000V. It has a nominal apparent power of 15 kVA and a nominal active power of 15 kW. The inverter's reactive power range is 0 to 9.0 kVAr, and its nominal AC voltage range is 3P+N+PE to 230/400 V (+/- 20%). The maximum AC current is 3×22.6 A, and the maximum DC current per input is 12.0 A. The inverter has three MPP trackers and three DC inputs (Sunclix).

The FLX PRO 15 inverter has a noise level of 55 dB and measures 570 × 774 ×356 mm. It weighs 39 kg and has an IP65 degree of protection in accordance with IEC 60529. Overall, the FLX PRO 15 inverter is a reliable and high-quality option for solar energy systems in small and medium-sized households.
