Distributed Storage

China’s Envision has launched a 12.5 MWh battery storage system and started production of a 790 Ah lithium iron phosphate (LFP) cell, as it advances an AI-driven storage strategy.

The new Anker Solix Solarbank Max AC steps up from balcony-scale storage with a 3.5 kW inverter, plug-in capabilities for do-it-yourself (DIY) ease of installation, and expandability to 42 kWh, priced from €2,229.

In its first monthly column for pv magazine, experts from UK-based consultancy Ricardo, part of the WSP Group, explain how UK will soon allow low-cost plug-in solar panels under 800 W to be installed without a qualified electrician, making home solar more affordable and accessible. These portable systems, expected on sale by summer 2026, could significantly boost household solar adoption while complementing the country’s wider renewable energy growth.

China’s Sigenergy has announced a Hong Kong initial public offering (IPO), with shares open to retail investors until April 13 and backing from major international asset managers.

Brazil’s National Electric Energy Agency (Aneel) has authorized a 5 MWh battery system co-located with a solar plant, setting a regulatory precedent for integrated storage.

A Japanese–Chinese team developed a titanium molten salt redox-flow battery using abundant titanium ions and molten salt electrolytes to enable high-voltage, fast, and stable grid-scale energy storage. The system demonstrates high efficiency of over 97%, strong cycling stability, and improved cost and scalability compared to vanadium-based batteries, with further optimization underway.

IT security firm Jakkaru has identified a vulnerability in microinverters from AP Systems that could enable a “kill switch” scenario, potentially shutting down tens of thousands of inverters simultaneously and disrupting grid operations.

A new sodium-ion cell for ESS may further improve competitiveness in large-scale systems against the weight of the lithium-ion battery sector.

Lambda Wärmepumpen GmbH said its Eureka heat pump series uses a patented fluid mechanics system that reportedly improves heat transfer by four to six times while maintaining a temperature difference of just 3 K between the air and the refrigerant. Its seasonal coefficient of performance ranges from 4.50 to 6.10.

The US manufacturer has launched a modular residential battery for Europe, scalable from 7.3 kWh to 47.9 kWh with LFP chemistry and IP65 protection. The system offers up to 23.3 kW nominal power, over 6,000 cycles, and a depth of discharge of 90%.
