From ESS NewsStationary BESS are typically categorized by size, beginning with stack systems, followed by cabinets, and ending with containerized units. A large container can store up to 5 MWh of energy. Cabinets typically hold several hundred kilowatt-hours, while stacks are mainly used by homes and small businesses. Although smaller BESS types can be combined, they have rarely been used to match the capacity of larger systems – until now. To continue reading, please visit our ESS News website.

From pv magazine GermanyLarks have become rare in the German agricultural landscape. But at this moment, I can hear several at once. There, just 30 meters away, another one takes flight. From the ankle-high grass, it soars vertically into the sky and, after just a few meters, begins to trill loudly. The nest is probably hidden somewhere below it on the ground, well camouflaged against accidental discovery.

From pv magazine GermanyAnyone who walked through the halls of Intersolar Europe in Munich with their eyes open could discover, in addition to standard module technologies such as Topcon and heterojunction, double-sided and with back contacts, other modules that are not in line with the mainstream and are currently waiting for a breakthrough.

From pv magazine GermanyAfter a sunny winter day, an electric vehicle and home battery may be fully charged. However, overnight, the storage capacity in the house decreases, forcing the operator to draw power from the grid despite unused solar energy. Many EV owners seek bidirectional charging, or vehicle-to-home (V2H), but it has not yet become standard. Today, many EVs can connect to small appliances, such as a vacuum cleaner or camping stove, via a 230 V socket.

From ESS NewsDegradation of individual battery cells is a driver in BESS losing storage capacity over time. Small differences in quality, which initially seem minimal, gradually increase and since the cells are connected in series, and can only be charged and discharged together, if one fails, it affects the performance of the entire string. With regular balancing coming at the expense of efficiency, systems that do not require an external inverter are attractive.
