Forecast-Based Battery Charging: How to Store Solar Energy Properly Instead of Curtailing It

The aim of PV system operators is to achieve the highest yield and most efficient operation. However, reality can be rather different. Some Distribution Network Operators (DNO’s) or local connection conditions for residential storage systems require a limitation on the maximum PV feed-in power at the grid-connection point. So, if a PV system produces too much energy, it has to be curtailed and the highly valuable resource, solar power, goes to waste. SMA’s forecast-based battery charging feature helps combat this.

Grid Feed-In Prohibited — Energy Management Desirable

Energy management systems in companies in Nicaragua prevent solar power from finding its way into the utility grid. In this Central American country, no specifications have been defined for the grid feed-in of self-generated electricity. Grid operators fear that the electricity grids could collapse under the strain. For ECAMI S.A., a company that plans and builds renewable energy systems, SMA Data Manager M powered by ennexOS was just what it needed.

Energy transition live: In Frisia there is a unique battery-storage system for renewable energies

1144 castle church – 1671 orphanage – 1848 windmill – 2018 hybrid mass storage: Most of the sites in Varel, a city in Lower Saxony, were built some centuries ago. But this year another one joined them: An intelligent battery mass storage that stabilizes the utility grid and intermediately stores excess energy from renewable energy sources until it is needed. And everyone benefits from this.

Short-Term Weather Forecasts Save Additional Diesel Power in PV-Diesel Hybrid Systems

Factories located far away from utility grids depend on electricity supplied by diesel generators. For financial reasons, operators often rely on what is referred to as hybrid supply, i.e., a combination of a diesel system and PV system. The core element of the PV-diesel hybrid solution is the SMA Fuel Save Controller. It regulates the electricity supply to ensure that priority is given to cost-effective solar energy.

ennexOS: How Does SMA’s Energy Management Platform Work?

More and more companies and private households are discovering energy management to reduce their energy costs, to become more independent from electric utility companies and to secure a sustainable energy supply at the same time. For effective energy management, all energy sectors must be linked and their control optimized. Another important factor is the direct integration into the electricity market. To easily implement this, SMA has developed ennexOS. What is the IoT platform for energy management able to do and how does it work?

Reducing Costs and Protecting the Environment: How Does Energy Management Work?

Energy costs are a serious issue for companies because prices for electricity, oil and gas are continuing to rise. It is therefore becoming increasingly important to use energy efficiently for lighting, machinery, equipment, heating, cooling and air conditioning. This not only saves money but also is good for the environment and the company’s image. The best way to achieve the highest possible energy efficiency within the company is focused energy management.
