GoodWe ESA Series: 3-10kW Single Phase Home Storage Solution (HV)
An integrated all-in-one solar and storage solution.
Product Overview
The GoodWe ESA Series is a fully integrated all-in-one solar and storage solution that combines an inverter and battery in a pre-wired, modular design, significantly reducing installation time and complexity. Engineered for flexibility, the ESA system allows seamless expansion to meet evolving energy needs. The 5kWh and 8kWh battery modules support 1C charging/discharging and can be mixed within a single stack, supporting up to 48kWh capacity and up to 6 stacks in parallel. The ESA provides UPS-level, full house backup (63A) without requiring a gateway. Models feature 2-4 MPPTs, each supporting up to 26A short-circuit input current. Safety features include 6-level battery protection and AI-driven AFCI 3.0 as standard. With low noise levels of less than 35dB, the ESA is suitable for a wide variety of applications.
Key Features:
- Optimized Performance: 1C charge/discharge for rapid energy cycling, fanless design for quiet operation (noise <30dB), 20A per string, and 200% PV oversizing.
- Superb Safety & Reliability: Advanced 6-layer safety protection, heating mode for reliable performance down to -20°C, and AI-driven AFCI 3.0 for enhanced safety.
- Flexible & Adaptable Applications: Dual output ports for simplified installation and off-grid capability, flexible battery mixing with different capacities or older/newer batteries, and support for full backup load with 63A output.
- Smart Control & Monitoring: Seamless switching to backup power in less than 4ms, and one-click upgrade and configuration options.
