Weiheng Ecactus has unveiled its new Myrtillo battery system, with a capacity of 4.99 kWh, giving users the flexibility to connect up to six units in parallel.
Chinese battery supplier Weiheng Ecactus has launched “Myrtillo”, its new 4.99 kWh high-voltage storage system for residential applications.
The systems feature lithium iron phosphate (LFP) batteries from unspecified top global suppliers. “Myrtillo uses industry-leading LFP battery cells, which have passed the industry’s most stringent safety certification, UL 9540A,” a company spokesperson said. pv magazine. “More sensors, heat-resistant insulation pads and explosion valves make safety at the module level promising.”
The company said the new battery gives users the flexibility to connect up to six units in parallel and achieve a capacity of 29.9 kWh. It measures 600mm x 300mm x 575mm and weighs 69kg.
The battery specifications include a nominal voltage of 96 V, an operating voltage of 84-108 V and an IP65 protection level. It also features natural cooling, a 90% depth of discharge and a 4-layer protection design, including a built-in fire protection module.
The new product reportedly has a life cycle of more than 10,000 cycles.
“Fully proprietary BMS and EMS, which integrate cloud-native technology and a machine learning platform, provide prediction, planning, control and protection throughout the device lifecycle,” the spokesperson added. “Remarkably, it delivers 100% power even at -20℃, ensuring uninterrupted energy supply regardless of the environment.”
The system also features an integrated plug-in terminal that replaces traditional manual wiring and ensures trouble-free installation, according to the manufacturer. “With guided shortcuts between battery modules, auto-plug functionality is activated once they are stacked, eliminating the need for cables,” the spokesperson said, noting that a stackable installation would take 15 minutes.
