Commercial self-consumption of solar power

Information for plant designers

Since July 1, 2010, the self-consumption of solar energy has become an attractive proposition for commercial consumers as well. Yet what level of self-consumption can be achieved in a commercial context? And what are the factors that can influence?

Simple and efficient directly into the grid

Reliable connection to medium voltage for trouble-free feed-in

Today, up to 99 % of the power genrated by PV power plants flows into the medium voltage grids all around the globe.

Practical knowledge about SMA system communications

SMA's system communications open up a multitude of possibilities for you. With our three-part series we can help you to use them optimally.

A matter of attitude (2)

Practical knowledge of SMA plant communication

Essential for the manifold functions of the Sunny WebBox: the correct configuration - from the IP address to date and time. For this reason, the second part of our series deals exclusively with the configuration of the SMA data logger.

SMA shifts the phase

Why reactive power is important - and no problem with SMA technology

What is reactive power? What is it good for? What are the requirements for PV systems? Most important realization: reactive power is no problem at all. It is actually a solution for some problems.

PV Inverters - Basic Facts for Planning PV Systems

The inverter is the heart of every PV plant

Inverters: power electronics for a clean power supply

What actually are inverters? What does one need them for, how did they function previously and how today? Which requirements are place on PV inverters today? And which in the future?

Which inverter is the right one?

The choice of PV modules is virtually endless

The choice of PV modules is virtually endless. Fortunately, there is a right inverter for every module technology.

Back to the Future

With its Sunny Boy HF, SMA has reinvented the transformer inverter

The new Sunny Boy HF is more efficient, more flexible, and easier to install than comparable models on the market, primarily because it combines a concept SMA developed 19 years ago and state-of-the-art technology.
