Solarwatt launches new inverters, batteries
Solarwatt has launched six new inverters and batteries as part of its Solarwatt Home line and outlined its future strategy. The German company, currently in transition, recently closed its solar module plant in Germany and announced staff reductions.
New grid forming strategy for solar batteries
A group of scientists from a major Chinese grid operator have proposed to use an enhanced version of the particle swarm optimization algorithm to adjust inertia and damping coefficients in batteries linked to PV systems. Their approach was validated through a series of simulation and was found to enhance transient performance.
Indian state of Rajasthan tendering up to 2 GWh of battery storage capacity
State utility Rajasthan Vidyut Utpadan Nigam Ltd (RVUNL) is tendering for 500 MW/1 GWh of standalone battery energy storage systems (BESS) and may allot double that capacity, given sufficient demand.
Phnix presents new residential air-to-water heat pumps
The Chinese manufacturer said its new Heco series uses propane (R290) as a refrigerant and includes five models with a nominal capacity ranging from 6 kW to 17 kW.
UK startup launches AI air-source residential heat pump
UK-based Wondrwall says its new heat pump has a coefficient of performance of up to 4.99, with an inlet-outlet temperature of 30 C to 35 C. The system is based on the company’s AI-powered Home Energy Management System (HEMS) to efficiently manage household energy flows.
New research optimizes energy density in sodium-ion batteries
A machine learning model has identified Na[Mn0.36Ni0.44Ti0.15Fe0.05]O2 as the optimum composition to attain the highest energy density for sodium-ion (Na-ion) devices.
Hydrogen detection system for safety, quality control
Researchers in Japan have developed an optimized hydrogen gas measurement using TDLAS technique. It is reportedly able to achieve a detection range of hydrogen gas concentration of 0.01% to 100%. The group said that it can improve hydrogen safety and in turn, its adoption.
