Swiss researchers developing control algorithm for grid-forming inverters
Researchers at ETH Zurich have patented a grid-forming inverter algorithm that stabilizes frequency while protecting devices from damage by independently controlling frequency, voltage, and current.
Sungrow releases modular inverter for utility-scale solar
The Chinese manufacturer said its new product uses inverter units with an output of 800 kW, of which 12 can be connected in parallel. It can work in weather of up to 52 C.
Fronius launches hybrid inverters for residential, commercial applications
The Austrian manufacturer said its new hybrid inverters can increase the usable output of the PV system to up to 150%. They are available in six version with rated AC power ranging from 15 kW to 33.3 kW.
EcoFlow launches balcony PV system, batteries with AI features
EcoFlow’s new Stream series, its second-gen balcony solar plant, enables battery coordination and plug-and-play solar for distributed batteries, plus third-party microinverter coordination for its new battery.
Poland’s micro-solar growth slows slightly in 2024
Poland’s micro-scale solar sector grew to 1.5 million systems and 12.7 GW in 2024, with slower growth in both new installations and energy exports, according to the country’s energy regulator.
Asymmetrical 49-level cascaded inverter for PV applications
Researchers in Iraq have designed a multi-level cascaded inverter that can purportedly produce high-quality sinusoidal output voltage and current waveforms, while reduing harmonic distortion. It uses the so-called phase disposition level-shifted pulse width modulation (PDLSPWM) control technique to operate the switches in the circuit “effectively.”
GoodWe unveils hybrid inverters for large residential applications
GoodWe says its new EHB single-phase hybrid inverters suit larger residential energy storage applications with the series supporting 200% PV oversizing, allowing for systems up to 20 kW in size.
SMA releases 9.6 kW and 11.5 kW hybrid solar inverters
SMA America introduced two larger power classes to its Sunny Boy residential solar inverter line.
German startup launches bidirectional charging kit for EVs
Energy Island Power, a German startup, has developed a connection kit that allows electric vehicle owners to use their car’s power to support home energy needs by integrating with the solar inverter and the home grid.
Dual-component controller for three-phase solar inverters can reduce overshoot to less than 0.33%
An international research team has conceived a dual-component controller for three-phase inverters that can reportedly achieve faster settling times, reduced overshoot and more stable current tracking compared to conventional controllers.
