Description
W5-E5 is a comprehensive, wall-mounted home solar lithium battery from Lithium Valley, purpose-built for residential energy storage. This no-display variant delivers the same rugged, long-life LiFePO4 performance as the standard W5-E5, in a simplified, cost-effective format for installers and homeowners who don’t need an onboard screen — monitoring instead happens entirely via Bluetooth (BLE) and app connectivity.
At the core of the W5-E5 (No Display) is a rated capacity of 100Ah at 51.2V nominal voltage, built with A+ grade LiFePO4 cells rated for 6,000 cycles at 80% depth of discharge (25°C/0.5C) — a long-term, low-degradation energy storage solution for daily solar cycling. The independently designed Battery Management System (BMS) has been verified compatible with inverters from multiple brands, supporting both hybrid grid-tied and off-grid operation modes, giving installers real flexibility when integrating into existing or new solar systems.
Despite lacking a physical display, the W5-E5 (No Display) doesn’t compromise on visibility — BLE firmware updates and real-time BMS monitoring let homeowners track battery status, configure settings, and stay informed about system health directly from a mobile app. Conversion efficiency reaches 99% at 25°C/0.5C, ensuring minimal energy loss between charge and discharge cycles.
For growing energy needs, the W5-E5 (No Display) is scalable up to 20 units in parallel, reaching a maximum system capacity of 102.4kWh — making it equally suited to a single-household starter system or a larger multi-unit residential energy bank. Rated IP20 for indoor installation and built to operate across a wide –20°C to 60°C temperature range, this battery is certified to CE, UN38.3, and MSDS standards, offering a safe, reliable, and budget-conscious energy storage option for solar self-consumption and backup power.
