GoodWe ESA-Athena 0.8 kW/3.84 kWh – Micro Storage Set for Balcony Solar
All-in-one energy storage system with 3.84 kWh total capacity – base unit plus one extension battery for increased self-consumption on your balcony.
The GoodWe ESA-Athena 3.84 kWh set combines the base unit (EAA0800-03-00P) with one extension battery (BAG1900-02-00P) to form a compact micro storage system with 3.84 kWh total capacity – the ideal addition to your plug-in solar device or balcony solar system. Thanks to 4 independent MPP trackers, each PV module is optimised individually, which is especially beneficial under partial shading on balconies. If your energy needs grow further, the system can be expanded with up to 3 additional modules to a maximum of 9.6 kWh.
Features
- 4 independent MPP trackers: Module-level optimisation, up to 4 PV modules connectable (depending on their output voltage).
- Plug-and-play installation: Simple, tool-free setup and stacking.
- 800 W feed-in power: Matches the German balcony solar limit, no extra accessories needed.
- Increased self-consumption: 3.84 kWh storage capacity for significantly more stored solar power instead of unused grid feed-in.
- Further expandable: Up to 3 additional extension batteries stackable, mixing old and new modules supported.
- Heating technology: Reliable operation down to -20°C.
- Backup power & scheduling: Automatic standalone mode, mobile outdoor operation, and TOU scheduling (see below).
- IP65 protection rating: Weatherproof for outdoor use.
- SEMS+ App: Remote monitoring via Bluetooth/WiFi.
Backup Power, Standalone Mode & Scheduling
Automatic backup power (Backup port): A dedicated connection (Backup port) supplies selected, important loads independently of the normal grid connection. In the event of a power outage, the unit detects the missing grid voltage at the GRID port and automatically switches from grid-tied mode to standalone mode in under 10 ms, supplying this backup circuit with up to 1.5 kVA. For pure mobile outdoor use – i.e. taking the base unit to a different location, such as camping or the garden – a deliberate, manual reconfiguration is required: the grid, backup and PV cables are disconnected, the series connection to the extension batteries is removed, protective caps are fitted, and the unit is switched to outdoor mode at the press of a button.
The system also supports a TOU mode (Time-of-Use): in the SEMS+ App, time windows can be set in which the battery charges from the grid during low-demand periods and supplies the load from the battery during peak periods – matching known off-peak/peak tariff times. The exact possibilities for connecting to dynamic electricity tariffs should be checked directly with the manufacturer or tariff provider before purchase. Independently of this, a compatible smart meter such as the Shelly Pro 3EM can optionally be added to capture actual household consumption in real time and optimise self-consumption accordingly. A smart meter is not included in the scope of delivery – without one, the system operates with output power designed for 800 W from the factory. The list of supported smart meter models is regularly updated and expanded by the manufacturer, so we recommend checking current compatibility before purchase.

Safety Instructions:
- Installation by qualified personnel: The installation of a PV storage system must only be carried out by qualified professionals.
- Ensure ventilation: Install the storage system in a well-ventilated area to ensure heat dissipation and prevent the risk of overheating.
- Observe fire safety regulations: Battery storage systems should be installed at a safe distance from flammable materials.
- Ensure accessibility: Install the storage system in an easily accessible location to allow for safe maintenance and emergency shutdown.
- Mechanical safety: Ensure that the battery storage system is securely fastened and protected against tipping.
- Danger from high voltages: Battery storage systems can generate dangerously high voltages. Avoid contact with exposed terminals or wires.
- Observe polarity: Ensure that the terminals are correctly polarized to avoid short circuits and damage.
- Suitable cables and fuses: Use only cables, connectors, and fuses recommended by the manufacturer.
- Grounding: Ensure that the battery and the entire PV system are properly grounded.
- Avoid short circuits: Keep tools, wires, or other conductive objects away from the battery terminals.
- Proper use: Use the battery only for its intended purpose and under the specified conditions.
- Proper disposal: Batteries contain environmentally hazardous substances and must be recycled or disposed of in accordance with applicable regulations for electronic waste.
- Danger from residual charge: Be aware that batteries can retain dangerous residual charges even after being switched off.
- No modifications: Unauthorized alterations, modifications, repairs, and opening of the product are prohibited.
