Volker Wachenfeld of SMA explores some technical and policy factors driving growing use cases for refurbishing home PV systems to add energy storage, and the markets where this is already gaining traction as an idea.

In contrast to “behind-the-meter” household energy storage systems, whose operational strategy is generally aimed at local financial optimisation of power consumption, the use cases for battery technologies on an industrial scale are primarily determined by the requirements of the electricity supply grids, particularly the regional distribution grids. SMA’s Voker Wachenfeld and Dr Alexsandra Sasa Bukvic-Schaefer take a closer look at some of the demands and applications driving the sector forward.

Through a brief history of batteries and some findings from his own team’s work, Volker Wachenfeld of SMA Solar Technology answers a frequently asked question in energy storage; how can compatibility with the existing variety of batteries in the market be put into practice?

It is sometimes said that as of today there is no business case which delivers economic viability for decentralised residential battery storage systems owned by private end customers- without subsidy programmes- or they propose other solutions which offer higher benefits. Despite the discussion, the market already offers a variety of storage solutions which seem to be well accepted by the end-customer. Volker Wachenfeld of SMA explains the contrast.
