Alpha ESS SMILE-M5 Solar Battery System

At Trione Energy, we proudly supply and install the Alpha ESS SMILE-M5 solar battery.

The Alpha ESS SMILE-M5 is a single-phase all-in-one hybrid solar energy storage system. Combining inverter, battery and intelligent safety features into a compact stackable solution.

With a 5 kW hybrid inverter and scalable battery stacks offering 5–30 kWh usable capacity (100% depth of discharge), the SMILE-M5 delivers reliable backup and optimised solar capture (up to 200% PV oversizing).

Key Features

Stackable, modular design — 5 kWh battery modules, easy tool-free stacking to reach 30 kWh capacity.
Integrated hybrid inverter — 5 kW output with built-in backup (UPS class) so critical loads stay powered seamlessly.
200% PV oversizing capability — maximise solar generation yield and reduce payback period.
Built-in safety features, including aerosol fire suppression and rugged IP65 weather protection for both inverter and battery.
Quiet operation — < 35 dB sound during normal use; excellent for indoor or outdoor use near living areas.
Smart communications — Wi-Fi / Ethernet connectivity for remote monitoring and diagnostics.
