British startup Wondrwall has developed a hybrid battery-inverter system for homes, offering up to 25.6 kWh of energy storage capacity.
Wondrwall, a UK-based renewable energy company, has unveiled a new all-in-one battery and inverter system with a storage capacity of up to 25.6 kWh. The new product comes in two versions, with storage capacities of 6.4 kWh and 12.8 kWh, and allows additional batteries to be stacked.
“The modular design halves installation times, enhancing the commercial benefits of the new hardware,” the company said in a statement. “The accompanying intelligent EV charger, slightly larger than an A5 notepad, is compact, untethered and available in 7 kWh and 22 kWh options.”
The system features lithium iron phosphate batteries (LiFePO4), which provide a charging capacity of 3 kW in the smaller model and 6 kW in the larger model. The maximum AC power is 5 kW and 6 kW respectively, with a maximum PV power of 8 kW for the smaller model and 9 kW for the larger one.
Each system has two MPPT (Maximum Power Point Tracking) inputs and achieves an efficiency of 99.9%. The smaller system is 73 cm wide, 20.5 cm deep, 92.9 cm high and weighs 95 kg. The larger system measures 73 cm by 20.5 cm by 1,399 m and weighs 154 kg. Each additional battery unit adds 59.4 kg.
“The system uses our brand new AI-powered renewable home energy system, delivering significant performance and cost-saving benefits to users,” the company added. “Our proprietary home energy management system (HEMS) can use 20,000 individual data points, including weather forecasts, to anticipate needs and automatically reduce costs. The system also has the ability to charge cars and home batteries when prices are at their lowest or even negative.”
