The ACETECH-BOX12 is a premium 51.2V wall-mounted or floor-standing lithium iron phosphate (LiFePO₄) battery designed for reliable home energy storage. With a robust 280Ah capacity and 14.34kWh nominal energy output, it delivers superior safety through its UL-certified LFP cells and intelligent fire-extinguishing system. Engineered for versatility, it supports up to 15 parallel units (71.7kWh total) and seamlessly integrates with leading inverters like Growatt, Deye, and SMA via RS485/CAN communication. Its auto-heating function enables stable operation from -20°C to 65°C, while smart BMS allows remote monitoring and OTA updates. Backed by a 5-year standard warranty (extendable to 10 years), it offers 6,000+ cycles at 80% DoD for long-term sustainability.
