V-Tac's new 10 kWh lithium iron phosphate, wall-mounting battery system purportedly runs for more than 5,000 cycles.V-Tac has developed a new wall-mounted storage system for use with residential PV systems. The AT48-200H measures 660 mm x 855 mm x 360 mm and weighs 89.9 kg. It uses lithium iron phosphate (LiFePO4) as the cathode material. The UK-based LED lighting specialist said the lithium-ion system has a storage capacity of 10 kWh and a nominal voltage of 51.2 V. It has an ambient operating temperature range of -20 C to 70 C, with a recommended temperature range of 10 C to 45 C. "Tested and ...Den vollständigen Artikel lesen ...
