The French company says its Inelio thermal battery can store solar energy in the form of heat for heating and cooling applications, as well as for domestic hot water production, while maximizing self-consumption. It is said to be able to provide a hot water temperature of up to 65 C.
France-based FHE Group this week presented its thermal battery Inelio at the Energaia trade show, currently taking place in Montpellier, southern France.
“Our thermal battery can store solar energy in the form of heat for heating and cooling applications, as well as for domestic hot water production, while maximizing self-consumption,” said the company’s technical director Jonathan Iacono . pv magazine. “If the PV system is accurately dimensioned, the battery can guarantee 100% self-consumption.
The battery measures 75.4 cm x 57 cm x 143 cm and has a weight of 150 kg. It has a storage capacity of 2.5 kWh and a charging depth of 100%. It can supply hot water with a temperature of up to 65 C. The heating power is 2.5 kW and the cooling power is 5 kW.
The system uses ammonia (R717) as a refrigerant and has a sound power level of 35 dB(A). It reportedly has a life cycle of over 20,000 cycles and comes with a 20-year warranty.
“The system uses a fixed gas sorption system and operates without compressors,” Iacono said, noting that it also uses two thermal storage units and one storage tank.
“The core component is a solid gas sorption technology that relies on a thermochemical reaction between a solid material and ammonia, a natural refrigerant with a near-zero global warming potential,” he continued. This reaction absorbs or releases heat depending on the cycle phase, allowing efficient thermal storage and energy recovery.”
The system consists of a hermetically sealed sorption module with no moving parts, a thermal transfer heat exchanger and advanced control systems for predictive maintenance and seamless integration with renewable energy sources.
“The system is adaptable to residential, commercial and industrial applications, Inelio supports full energy autonomy and is compatible with various renewable energy systems. We often sell the system in combination with PV systems, because our approach is to provide a complete solution,” says Iacono.
FHG Group was founded in 2010 and is based in Perpignan, South-West France. It operates a factory near Rabat, Morocco.
