Viessmann launches new residential air-to-water heat pumps
The Germany manufacturer said its new heat pump systems use propane (R290) as the refrigerant and are able to provide a maximum flow temperature of 70 C. Their coefficient of performance ranges from 4.7 to 5.1.
Tigo Energy releases off-grid solar package
The off-grid solution includes module optimizers, an inverter, a battery, and an automatic transfer switch.
Enphase misses Q1 2025 revenue target, trims margin outlook on tariffs
Enphase Energy has posted $356.1 million in revenue for the first quarter of 2025, falling short of expectations. The solar microinverter and battery storage provider says it has lowered its margin outlook due to rising tariff pressures.
Ireland issues tender to stimulate limited industrial heat pump market
Government-run Sustainable Energy Authority of Ireland (SEAI) is tendering for the provision of technical and advisory support services for its grant programs aimed at organizations in Ireland planning to decarbonize. The tender follows a report by the SEAI that showed Ireland has a limited market for industrial heat pumps and called for greater outreach and support for businesses to install the technology.
Tariff uncertainty grips US battery development
The Trump administration’s China tariffs have piled atop existing and developing trade barriers on battery energy storage systems, components, and materials – destabilizing the US energy storage industry. While existing inventories will allow project development to move forward in the short term, uncertainty extends across the supply chain, including to prospective manufacturers.
Home batteries have same probability of catching fire as other appliances
New research from Germany shows that home batteries have much lower chances of being hit by fire than electric vehicles and most home appliances. The researchers warned, however, that fires in residential storage systems can be more dangerous than those of burning tumble dryers.
1Komma5° releases residential battery for non-PV homeowners
1Komma5° has launched PowerHarvester, a lithium iron phosphate battery system for residential customers without solar. It is offering six power classes and storage capacities from 7.7 kWh to 27.2 kWh.
Rhoss launches reversible heat pumps
Conceived for industrial applications, the novel heat pumps can reportedly deliver hot water at 65 C from -10 C up to 35 C of external air, and hot water at 55 C down to -20 C of external air. Their coefficient of performance reaches up to 3.60.
E.ON partners with Superdielectrics to develop novel polymer-based energy storage
E.ON is now working with a UK-based battery tech firm to advance more environmentally friendly energy storage for households.
PV-driven heating, cooling system for supermarkets
Scientists in China have developed a novel PV-powered cooling and heating system that combines a water-cooled gas cooler and an air-cooled gas cooler. The system went through a series of simulations and showed it can potentially achieve a coefficient of performance of up to 7.34.
