The MV-Inverter Station: centerpiece of the PV eBoP solution

Use of renewable energy sources is growing at a tremendous pace. A once static power generation landscape of large, central power plants is transitioning into a flexible, intelligent, and increasingly distributed system comprising many different actors. The intermittent, fluctuating nature of electricity feed-in from distributed generating sources, however, poses major challenges for power grids, and significantly affects the stability of medium-voltage and low-voltage networks.

What’s needed are comprehensive approaches and customized products and systems serving a broad range of intelligent infrastructure and energy storage solutions, ensuring­ sustainable, reliable, and stable grids – for today and the future.

When it comes to state-of-the-art power grids, Siemens offers innovative solutions and comprehensive experience across the entire range of electrotechnical equipment for photovoltaic systems, including optimum interconnection of energy storage systems and even complete microgrids. The new electrical Balance of Plant (eBoP) solution for photovoltaic installations enables solar power to be intelligently integrated into the grid.

The portfolio includes all electrotechnical equipment needed. Siemens offers complete end-to-end planning, engineering, and financing, all the way to commissioning and service.

Smart power distribution:

PV power distribution in perfect balance

With fluctuating power generation and everchanging demand, innovative ideas are needed for PV installations to ensure consistently stable and reliable grid operation.

The PV eBoP solution from Siemens provides the right answer: a complete package of proven components, modern systems, and comprehensive service offerings.

This total package comprises an end-to-end power distribution solution – from the combiner box right through to the mediumor high-voltage grid connection.

Bundled power: the Combiner Box

The combiner box combines the output of multiple PV modules, protects the electrical components, and forwards important data and measured values. It’s also extraordinarily robust and is suitable for use in the most demanding climatic environments.

A MV-Inverter Station makes it all possible: skid or container

A highlight of this chain is the MV-Inverter Station, which comprises the switchgear, transformer, and inverter. With its broad portfolio of switchgear, Siemens offers the

right solution for any application – reliable and maintenance-free, for any climate. Their outdoor housing allows these switchgear to be installed in PV systems with no additional station enclosure. The state-of-the-art inverters can be operated at DC input voltages of up to 1,500 volts. The transformer, specially optimized for operation with PV inverters, ensures reliable and efficient connection to the medium-voltage grid.

Hydrogen generation with SILYZER

Siemens generates „green“ hydrogen from renewable energy using Proton Exchange Membrane (PEM) electrolysis, and this is making an important contribution to the global energy transition. The SILYZER product line helps integrating fluctuating energy sources like sun and wind in your process.
