The SUNSYNK-L5.3 is a high-performance lithium iron phosphate (LiFePO4) battery designed for energy storage in residential and commercial applications. With a 5.32kWh capacity and scalable up to 170kWh by connecting up to 32 units in parallel, it offers flexibility for growing energy needs. Built with a robust Battery Management System (BMS), it ensures safety through protections against overcharge, over-discharge, over-current, and extreme temperatures. Its wall-mounted or rack-mount design saves space, while the IP65 rating ensures durability in diverse environments. The battery features low self-discharge, eco-friendly materials, and remote monitoring via the Sunsynk Connect App. Ideal for solar systems, it supports reliable power backup, long cycle life (6,000+ cycles at 90% depth of discharge), and seamless integration with inverters. Maintenance-free and equipped with self-cooling technology, it operates quietly and efficiently in temperatures from -20°C to 55°C.
