Inverters

Sigenergy has launched a 166 kW IP66-rated inverter for C&I solar and storage offering nine MPPT trackers and flexible AC/DC connections. The launch coincided with the opening of its Nantong Smart Energy Center, a 136,000 m² facility for R&D, manufacturing, and global delivery.

A new global dataset of 119 energy-sector cyber incidents from 2022–2024 shows EU and BRICS countries, followed by the US, are most affected. Attacks targeted power, oil, gas, and nuclear infrastructure, driven by both financial and political motives, with diverse threat actors involved.

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.

Bifacial PV modules, string inverters and advanced trackers are becoming the preferred technologies in utility-scale solar project design, according to new data from RatedPower.

India-based Involtics has launched its GTSI series of single-phase hybrid inverters in 3 kW, 3.6 kW, 5 kW and 6 kW sizes for residential solar systems.

The 3 kW N3300S inverter combines a pure sine wave inverter with an integrated MPPT solar charge controller for small residential and hybrid PV systems. The unit supports multiple power sources, flexible battery chemistries, and rapid grid/off-grid switching.

EcoFlow has unveiled the single-phase Ocean 2 all-in-one battery inverter at Key Energy in Rimini. The system features a more compact 5 kWh LFP battery stackable up to 30 kWh and offering 100% depth of discharge, 3.4 kW discharge power, and IP66 protection.

The Iraqi Customs Authority has cut customs duties on solar energy systems from 33% to 5% – covering PV panels, inverters, cables, and lithium batteries – to accelerate solar adoption, following financing support from the Central Bank of Iraq.

The inverters offer up to 99.2% efficiency, 200% PV oversizing, dual battery inputs, IP65 protection, and support for installations up to 144 kWh of storage capacity.

An Australian research team has developed a five-step, rule-based method that detects and classifies underperformance in PV systems using only AC-side inverter data. Validated across more than 1,000 systems, the approach offers a low-cost, low-intervention solution for improving reliability, fault response, and PV system performance.
