Alpha Ess SMILE-B3- PLUS with 5.04kw Module – (SMILE-B3-PLUS (AS4777-2 2020))
The SMILE-B3-PLUS is a modular, AC-coupled energy storage system with built-in inverter and LiFePO₄ battery, designed for retrofit or new solar installations. It combines a small inverter (~3 kW) with a 5.04 kWh battery module, and supports expansion up to ~30.24 kWh. It enables energy storage, self-consumption, and backup during grid outage — ideal for homes or small commercial setups.

- Delivery & return
Modular & Expandable Battery Storage
- The base unit provides 5.04 kWh storage, and you can expand by adding up to 5 additional battery modules (5.04 kWh each), enabling total storage up to ~ 30.24 kWh as needs grow.
Built-in Inverter + AC-Coupled Design — Retrofit-Friendly
- Comes with a built-in 3 kW inverter and is AC-coupled — making it compatible with most existing or new PV inverters. This makes it relatively easy to integrate into an existing solar system without redesigning the PV string.
Reliable Battery Technology & High Usable Capacity
- Uses LiFePO₄ battery chemistry (safe, long-life), with a design DoD (Depth of Discharge) up to 95%, and usable capacity per module around 4.79 kWh.
- Battery life/cycle-life is designed for long-term use.
Backup / UPS-Style Power with Real-Time Monitoring & Smart Features
- Provides “continuous 3 kW backup” — useful to power essential loads during grid outages.
- Supports 24/7 monitoring, remote system management (via AlphaCloud / Alpha ESS app), which helps in tracking battery status, grid/pv interaction, and optimizing use.
