Wondrwall, a UK renewable energy firm, has launched an all-in-one battery and inverter system with up to 25.6 kWh capacity. The system comes in 6.4 kWh and 12.8 kWh versions, with stackable additional batteries for scalability.

“The modular design halves installation times, enhancing commercial viability,” the company stated. It includes a compact, untethered EV charger, available in 7 kWh and 22 kWh options, about the size of an A5 notepad.

Using lithium iron phosphate (LiFePO4) batteries, the system provides 3 kW charging power for the smaller model and 6 kW for the larger, with maximum AC outputs of 5 kW and 6 kW. The maximum PV input is 8 kW for the smaller version and 9 kW for the larger. Both models include two MPPT inputs and 99.9% efficiency.

The smaller system measures 73 cm wide, 20.5 cm deep, and 92.9 cm tall, weighing 95 kg. The larger model is 73 cm by 20.5 cm by 1.399 m, weighing 154 kg, with each additional battery adding 59.4 kg.

“Our new AI-powered renewable energy system leverages 20,000 data points, including weather forecasts, to optimise performance and costs,” Wondrwall added. The system can automatically charge cars and home batteries at the lowest or even negative electricity prices.
