The new Dutch residence battery has a brand new twist on previous expertise: gel lead-acid batteries, for secure operation.
From ESS News
SS4U, a brand new firm from father or mother TSS4U, a Dutch off-grid photo voltaic specialist and engineering agency, has launched a brand new battery designed for residential use. It’s based mostly on what’s old-new-again expertise: lead-acid, with a twist.
The battery is a gel lead-acid implementation, developed in collaboration with VDL Groep, a diversified Dutch producer in power, mobility, tech, and extra. It options an built-in charging system designed by ESS4U, which optimizes battery life and efficiency.
A Qurmit system can retailer 17.6 kWh of power, emit 2.4 kW and cost 2 kW. The draw back is the load: the system weighs 550kg, in comparison with a extra frequent residence battery, just like the Tesla Powerwall 3, for instance, which shops 13.5 kWh and weighs 130kg, utilizing lithium iron phosphate (LFP) chemistry.
However, Qurmit’s benefits are that the batteries function between -40 C to 55 C, beating LFP batteries on the high and low finish, there isn’t any such thermal runaway or hearth hazard, and the substances from Europe, the corporate stated. , and made in Eindhoven.
In addition, recycling is easier, and the system can be utilized indoors. The firm claims a lifespan of 20-25 years.
Dop Brzesowsky, Managing Director of ESS4U, stated: “We have a few years of expertise in utilizing gel expertise for giant industrial off-grid photo voltaic power initiatives. After thorough analysis and a large throughout testing, we at the moment are on the level the place we are able to supply this fire-safe expertise within the type of a house battery. Qurmit battery cells consist of fifty% recycled materials and the entire home batteries are 95% recyclable on the finish of their life.
Brzesowsky continues: “Since our Qurmit residence battery is fireproof, we additionally clear up the insurance coverage drawback for small companies that wish to purchase a (residence) battery. Their insurance coverage typically doesn’t cowl the harm attributable to residence batteries based mostly on lithium-ion expertise, except sure further measures are taken, corresponding to hearth and explosion-free areas.
The firm advised the Netherlands-based media that it intends to supply a 90 kVA system that shops 740 kWh of power for the industrial and industrial sector.
Currently, installers providing residence batteries are situated within the Netherlands solely.
