Energy Storage

The Chinese manufacturer said the product line includes five models with outputs ranging from 25 kW to 50 kW, supporting charge and discharge currents of up to 150 A.

While solar modules and batteries have become icons of rapid progress, most energy models are still stuck in the past. A new global analysis shows that the cost of renewable energy has fallen far faster than expected. Solar PV, wind power, and battery technologies have already reached price levels that models once placed many decades ahead – a misplaced pessimism that risks misdirecting billions in climate investment and could distort long-term defossilization strategies.

The Chinese company says that its new ESA series is available with a hybrid inverter ranging from 3 kW to 10 kW and storage capacities of 5 kWh to 48 kWh. The IP66-rated product supports an MPPT current of up to 20 A on the PV side and allows 200% PV oversizing, according to the manufacturer.

Researchers in China developed a large-scale PV-thermal heat pump system using a liquid overfeed method that reportedly improves both thermal and electrical efficiency. Field tests showed up to a 4.81% boost in power generation and significantly reduced pressure losses compared to conventional systems.

Adani Group says it will install a 1,126 MW/3,530 MWh battery energy storage system (BESS) at its Khavda renewable complex, marking India’s largest and one of the world’s biggest single-site deployments.

The PPA price for pure photovoltaic projects has fallen by 20% over the past year, making such contracts less competitive. However, clear structures for bankable hybrid PPAs are now beginning to take shape, says Pieter van der Meulen, Senior Account Manager at LevelTen Energy, in an interview with pv magazine.

A key infrastructure asset at one of the world’s biggest batteries has reduced operations and delayed completion for more than six months, with few details made public regarding the critical asset.

Heat Pumps Watch will work to change consumer attitudes towards heat pump adoption by delivering evidence-based information on the technology aimed at professionals, policymakers and homeowners.

EFT Energy Solutions says its new Industrial Flex system, built around BYD lithium iron phosphate modules, applies residential-level standardization to the commercial and industrial (C&I) energy storage market.

The German company said its new device features a DC input supporting up to 3 kW of photovoltaic power. The heating output can be continuously adjusted between 0 W and 1,000 W. Priced at €549 ($635) including VAT, the heating element is designed for hot water storage tanks with capacities of up to 500 L.
