Alpha Ess battery (SMILE5-BAT 5.7kw)
SMILE5-BAT is a modular residential lithium-battery storage module (5.7 kWh nominal capacity) from Alpha ESS, intended for home solar + storage installations (especially for use with the SMILE5 hybrid inverter family). It uses safe LiFePO₄ chemistry, supports “plug & play” modular expansion (1–6 modules in parallel), and provides a compact energy storage solution useful for backup, self-consumption, or load-shifting.

- Model No.:SMILE5-BAT
- Delivery & return
Modular, Plug-and-Play Design
- The 5.7 kWh module can be used standalone or in parallel (1 to 6 modules) to scale storage capacity based on needs — allowing total storage up to ~ 34.4 kWh.
- Modular approach simplifies installation and future expansion without replacing whole system.
Safe & Durable Battery Chemistry (LiFePO₄)
- Uses LiFePO₄ (LFP) cells — known for better thermal stability, safer chemistry, and longer cycle life compared to many other lithium-ion types.
- Built with battery-management and safety compliance — suitable for residential use.
Good Usable Capacity & High Depth-of-Discharge (DoD)
- Nominal capacity: 5.7 kWh, usable capacity about 5.5 kWh (≈ 96% DoD) under normal conditions.
- This ensures efficient use of stored energy, maximizing value for home backup or solar self-consumption.
Long Lifespan & High Cycle Life
- Rated cycle life up to 10,000 cycles (at rated DoD) under test conditions.
- With proper use, this gives a long-term, durable energy storage solution for home.
Flexible Installation — Indoor or Outdoor, with Solid Warranty Support
- Enclosure and design: supports both indoor (IP21) or protected/ outdoor installation (IP65) — offering flexibility in where you place the battery module.
- Backed by a 10-year battery warranty (on the module) under correct installation/use conditions.
