Marstek has unveiled a plug-in storage system with a two-kilowatt-hour capacity. The device plugs into a standard household socket and is designed to store solar power from balcony systems or draw in cheap electricity from dynamic pricing tariffs.

Researchers at Germany’s Fraunhofer FKIE institute developed PowerRange, a virtual simulation platform that helps power grid operators safely test cybersecurity measures and respond to realistic cyberattacks. The platform supports both traditional and renewable grids, offering immersive training across IT, OT, and control systems while highlighting the importance of coordination, communication, and practical defense strategies.

The new prototype ranks among the most advanced sodium‑ion battery systems reported worldwide.

Australia’s rooftop solar market has bounced back into record-setting territory with 281 MW of new capacity registered across the country last month, marking the largest February total on record.

The electricity grid is a real bottleneck for energy in the United States, and it’s not only utilities and grid operators who are struggling. Grid congestion also puts pressure on renewable energy project owners and is as much a business problem as it is a technical one, writes Alon Mashkovich, CEO of energy management business software supplier enSights.

Malaysia’s rising power demand, driven by industrial growth and data centers, is exposing grid and capacity constraints, prompting policies like Corporate Renewable Energy Supply Scheme (CRESS) to enable corporate renewable procurement while maintaining system cost recovery. A key factor is the System Access Charge (SAC), whose uncertain future trajectory affects long-term solar PPAs and investment decisions, making scenario-based modelling crucial for assessing project bankability.

The country’s first solar-plus-storage project will be located on a 400 hectare surface near Kébili, a town in the south of Tunisia and one of the main cities in the Nefzaoua region.

Twelve photovoltaic storage systems with capacities of 5 kW or 10 kW were included in the comparison, among them several new products, all of which achieved efficiency class A. A new study – also examining efficiency losses when storing electricity from the grid – highlights the importance of highly efficient battery storage. The researchers also took a closer look at the warranty conditions of the devices.

The Chinese manufacturer said its new three residential battery lines support a depth of discharge of 90% and deliver over 6,000 cycles.

The new product has a maximum wattage of 725 W, a maximum current of 22 A, and a maximum efficiency of 99.6%.
