About This Item
- Complete Plug-and-Play System: Everything needed for balcony solar is in one box — 1,229Wh battery unit with integrated 400W micro-inverter, two 200W solar panels, mounting brackets, and all cables. No electrician required.
- 1,229Wh LiFePO4 Battery Storage: Stores surplus solar energy during peak daytime production for discharge during evening peak pricing hours, maximizing your financial return on solar investment and reducing grid dependency.
- Integrated 400W Micro-Inverter: The built-in micro-inverter converts stored DC battery power to standard 120V AC and feeds it directly into your home’s electrical circuit via a standard NEMA 5-15 plug — displacing grid electricity with solar-generated power.
- Smart Time-of-Use Optimization: Automatically calculates optimal charge/discharge timing based on your electricity tariff schedule to maximize financial savings. Stores solar energy when prices are low, discharges when prices are highest.
- Balcony Rail Mounting: Specially designed mounting system attaches securely to standard apartment balcony rails without drilling or permanent modifications. System can be removed when moving without leaving any trace.
- Anker App Full Control: Monitor real-time solar generation, battery state, grid export, and financial savings via the Anker app. View daily, monthly, and annual energy production and cost savings reports.
- IP65 Outdoor Rated: Full IP65 weatherproofing enables permanent outdoor installation on balconies, terraces, and garden areas in all weather conditions including heavy rain and extreme temperatures.
