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.

Power up in Down Under

Australia is one of the world’s most exciting and promising photovoltaic markets, which was once again confirmed in the course of a number of conversations with customers during my visit last week. In all probability, after its record year in 2018, the Australian PV market will significantly grow again to 4.4 gigawatts this year. In addition to photovoltaics, storage systems are becoming ever more important, not only for independent electricity supplies for homes but also, in particular, for the power plant segment.

Fridays for Future—Homework for Politics

Sixteen-year-old Greta Thunberg from Sweden has initiated a worldwide movement with Fridays for Future, which each week reminds us adults anew that we finally have to act to prevent climate change and leave behind a planet for future generations that offers them a livelihood.

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.

Renewable Electricity Supply for Nigeria

Plenty of oil, but little electricity. Nigeria may be rich in raw materials, however, electricity supply leaves much to be desired. SMA supports the energy transition in Nigeria’s commercial and rural energy supply with a range of intelligent solar solutions and local training programs. Solar micro- and stand-alone grids ensure sustainable economic development in this Sunbelt nation.
