The AlphaESS SMILE-G3-S3.6 is a 3.68kW single-phase hybrid inverter and the control unit of a SMILE G3 home energy storage system. It handles solar generation, battery charging and discharging, grid interaction and backup supply from one IP65 wall-mounted box, with no separate high-voltage battery box required.
• 3680W nominal AC output, single phase
• Dual MPPT with 200% PV oversizing up to 7360W recommended PV
• 97.3% maximum efficiency
At 3.68kW it qualifies for straightforward G98 notification in the UK, so there is no DNO approval wait. It pairs with either the 3.8kWh SMILE-G3-BAT-3.8S modules (up to around 15.4kWh) or the 10.1kWh SMILE-G3-BAT-10.1P modules (up to around 60.5kWh), and the lego-style modular design means capacity can be added later without replacing the inverter.
