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.”
Optimizing residential PV-driven heat pumps with lithium-ion batteries reduces LCOE by 7%
Scientists in Spain have simulated the combination of power-to-heat-to-power storage systems with lithium-ion batteries to supply energy needs and heat pump production of an electrified dwelling. PV self-consumption was found to increase by up to 20% and levelized cost of energy decrease by 7%.
Latin America’s largest solar-plus-storage project goes online
ContourGlobal’s site features six-hour storage capacity alongside 221 MW of solar generation capacity. It is located in northern Chile and is part of a portfolio acquired from Spain’s Grenergy last year.
Trina debuts 5 MWh energy storage system
The Chinese manufacturer said its new utility-scale battery uses 314 Ah cells with a 15,000-cycle lifespan.
French solar-plus-storage product ‘could provide grid flexibility of six nuclear reactors’
Octopus Energy Services has responded to the government’s decision to slash the payments made to solar home owners for their excess electricity by launching its SolarPlus, home solar-plus-battery product.
The rise of bankable BESS projects in Europe
As the renewable energy sector rapidly evolves, battery energy storage systems (BESS) are emerging as a critical pillar for decarbonization. However, with capital constraints and rising market volatility, not all projects are equally viable. At ABO Energy, we’re witnessing a shift in the investment landscape, where preparedness is the key to success.
Smoke and vanadium leak from Swiss home energy storage unit
Vanadium redox flow energy storage manufacturer Prolux Solutions said 50 l of vanadium electrolyte leaked from a residential unit in Arbon but no fire occurred.
Gerchamp launches energy management system for C&I applications
The Chinese company said its new all-in-one module has a DC input current of up to 70 A and a voltage range of 650 V-900 V.
Compression-assisted adsorption thermal battery prototype for seasonal heat storage
Chinese researchers have developed a thermal battery prototype using composite sorbents and have scaled it up via simulation to operate in real world conditions. A compression ratio from 1 to 4 reporteldy boosts average output heat power by 300%.
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.
