Tesla launches three-phase Powerwall 3P
The system integrates a battery, hybrid inverter, and home energy management system into a single device. It supports the integration of additional appliances, including heat pumps via SG-Ready interfaces. A connection to Tesla’s proprietary wallbox is also planned.
Cyber threats for PV: What are ransomware attacks and how do they work
Ransomware attacks encrypt or lock critical PV system data and control platforms, preventing operators from accessing or managing their assets until a ransom is paid. These attacks can disrupt operations, reduce energy production, and create safety risks, making robust backups, segmentation, and incident response essential for resilience.
AI-enabled hacks expose remote shutdown risk in microinverters
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.
SolarEdge launches Nexis hybrid inverter and high-voltage battery for residential PV
The Nexis solution combines a flexibly configurable hybrid inverter with a modular high-voltage battery offering up to 14 kW charging capacity per stack. The inverter delivers 8–20 kW AC power, supports up to 200% DC oversizing, and features IP65-rated design with integrated backup power.
Marstek launches 2 kWh plug-in battery storage system
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.
EU to ban Chinese inverters? – Commission proposal in Cybersecurity mulls ‘high-risk vendors-list’
The European Commission is revising its Cybersecurity Act. While presenting the proposals in European Parliament, the commission’s Executive Vice-President for Tech Sovereignty, Security and Democracy, Henna Virkkunen, said dependency on a very limited number of solar inverter suppliers could “pose a significant security risk.”
Biwatt launches commercial sodium-ion energy storage product
Biwatt has unveiled a 155 kWh sodium-ion battery energy storage system (BESS) for commercial and industrial (C&I) customers.
German wholesalers hit by six-figure losses from new solar module scam
Suspected fraudsters are using false identities to claim they are interested in solar modules. The wholesalers typically respond by delivering the requested products, but the scammers never actually pay for their orders. These are not isolated cases, as a clear pattern has emerged.
Switzerland to host world’s largest redox flow storage project
Flexbase plans to build a 500 MW redox flow storage project in Laufenburg in early 2025.
AP Systems presents single-phase hybrid inverter for balcony photovoltaics
Until now, balcony inverters were mostly simple micro inverters, with batteries integrated via MC4 connectors. A hybrid inverter should improve this situation.
