5.12kWh Portable Power Supply Wall-mounted LFP Battery

5.12kWh Portable power supply Wall-mounted LFP Battery

Product Overview

The XPB-512100 is a wall-mounted, low-voltage LiFePO4 energy storage battery engineered for residential solar backup, off-grid power supply, and small commercial energy projects, well-suited for the EU, Africa, and beyond. Rated at 51.2VDC and 100Ah with 5.12kWh of energy capacity, this battery uses Grade-A lithium iron phosphate cells for superior safety and a long service life. Its compact wall-mounted design saves floor space and enables straightforward installation for system integrators and end users. Up to 15 units can be paralleled flexibly to expand capacity as energy demand grows.

Core Technical Advantages

The integrated intelligent BMS provides comprehensive protection against overcharge, over-discharge, over-current, short circuit and over-temperature. It supports CAN, RS485, RS232, WiFi and Bluetooth communication protocols for seamless real-time monitoring and compatibility with mainstream 48V solar inverters. Equipped with active cell balancing, the pack maintains consistent cell voltage to maximise capacity utilisation and extend service life. It features an ultra-low monthly self-discharge rate below 3%, making it reliable for long standby backup applications on remote islands.

Adopting flame-retardant housing and a cell isolation structure, the battery effectively reduces thermal runaway risks for indoor household installation. It supports hot-swap parallel operation; single-unit replacement can be performed without shutting down the entire parallel system, greatly cutting downtime. Users can access smart local and remote monitoring with fault alerts via a mobile APP. The battery achieves ≥6000 charge-discharge cycles at 25°C under 80% DOD and allows 90% DOD to fully leverage stored energy.

It comes standard with an IP20 rating, with optional IP54 for humid island environments. Operating temperature ranges from 0~55°C and storage temperature ranges from -20~55°C for stable performance in diverse climates. CE, UL, UN38.3, MSDS and RoHS certifications are available to satisfy European and Oceania import compliance. Custom OEM & ODM services are offered, including custom casing, display, branding and communication parameter adjustments for wholesale partners.
