GoodWe ESA Athena S3 GW3K-EMA-G10 (ESS Hybrid Inverter)/Plug & Play (Type C socket)

The GoodWe GW3K-EMA-G10 is the hybrid inverter of the ESA Athena S3 all-in-one micro storage system, designed for plug-and-play installation — a one-person, five-minute setup in either wired or DIY plug-in mode, so it fits on a balcony, terrace or rooftop without a full electrical rebuild. It runs at 0.8 kW output by default, adjustable up to 3 kW by a qualified electrician per local rules, and draws up to 3.6 kVA from the grid. The PV side uses 4 MPPTs with 1.6× DC oversizing (up to 4.8 kW input, 60 V max, 13–48 V MPPT range) for strong harvest from split or shaded balcony arrays. It pairs with the 54 V GW3.0-BAT-LVD-G10 battery (1 to 5 modules, 3–15 kWh) and supports a 3 kVA backup output with a 10 ms switchover. Touch-safe <60 V DC architecture, 6-layer protection, AI-driven EMS via SEMS+ for dynamic-tariff savings, and a fanless design at <20 dB. Rated IP65, −20 °C to +55 °C, natural convection, wireless 4-unit parallel. Communication over RS485, LAN, WiFi and Bluetooth (Modbus-RTU); CAN to the BMS. 10-year warranty. Dimensions 480 × 170 × 290 mm, ≤15 kg.
