They are equipped with communication interfaces such as RS485 and USB for monitoring and control.

Key Features

Dual MPP trackers support asymmetrical loading, beneficial for installations with uneven solar exposure, such as East/West roof setups.
Models like the RPI M50A offer high power density and come with built-in surge protection devices and string fuses.
The SOLIVIA TL series is noted for its versatility and ease of installation, with a compact design and mounting plate for quick setup.

Applications
These inverters are suitable for large commercial and ground-mounted solar arrays, providing reliable performance and maximum energy yield even in challenging environmental conditions.

General Specifications
The document provides technical specifications for various Delta solar inverters, including the RPI M50A and SOLIVIA nano 260 models. Key parameters such as operating temperature, storage temperature, humidity, and maximum operating altitude are outlined. The RPI M50A model boasts a maximum efficiency of 98.6% and supports a nominal apparent power of 50 kVA, while the SOLIVIA nano 260 offers a maximum efficiency of 96% with a nominal power of 260 W.

Electrical Specifications
For the RPI M50A, the AC output specifications include a voltage range of 230 ± 20% / 400 V ± 20%, a nominal current of 72.5 A, and a frequency range of 50/60 Hz ± 5 Hz. The DC input specifications highlight a voltage range of 200 ... 1000 V and a maximum current of 100 A. The SOLIVIA nano 260 features a DC voltage range of 25 ... 50 Vdc and an AC voltage range of 230 V +/-10% / -20%.

Mechanical Design
The RPI M50A measures 740 × 612 × 278 mm and weighs 74 kg, while the SOLIVIA nano 260 is more compact at 227.6 x 211 x 33.4 mm and weighs 1.3 kg. Both models include integrated cooling systems and connectors for AC and DC inputs.

Safety and Standards
Both inverters comply with safety standards IEC62109-1 / -2 and have protection degrees of IP65 for the RPI M50A and IP66 for the SOLIVIA nano 260. They include features such as configurable trip parameters, insulation monitoring, and anti-islanding protection.
