GoodWe ESA Battery Module 8.0 kWh GW8.3-BAT-D-G20

GoodWe ESA Battery Module 8.0 kWh GW8.3-BAT-D-G20

High-voltage battery module for the GoodWe ESA series (5-30 kW) – stackable, combinable with other capacities, integrated fire protection.

The GoodWe ESA Battery Module 8.0 kWh (BAE8000-06-00P) offers the highest system power among the ESA battery modules and is particularly suited for applications with high power demand – such as peak shaving, e-mobility or rapid discharge cycles. With an integrated DC-DC converter, the module can be flexibly combined with other capacities – even when retrofitting at a later stage. LFP cell technology ensures high safety and long service life, while a multi-level safety concept including integrated aerosol fire suppression provides additional protection at module level.

Features

• Integrated DC-DC converter: Enables flexible combination of different capacities and subsequent expansion.
• High system power: ≥8,000 cycles LFP cell technology, up to 1C charge/discharge rate – ideal for peak shaving and e-mobility.
• Integrated fire protection: Aerosol fire suppressant and heating function down to -20°C as standard in every module.
• Flexible stacking: Up to 4 modules per tower freestanding, or up to 6 modules with wall mounting.
• IP66 protection rating: Suitable for indoor and outdoor installation.
• TÜV-certified low noise: ≤29 dB operating noise – Grade A Low-Noise certification by TÜV Rheinland.
• AI-powered energy management: SEMS+ platform automatically optimises charge/discharge cycles based on solar forecast, consumption and electricity tariff.
• 10-year manufacturer's warranty: Performance guarantee of at least 70% usable capacity over the warranty period; extended warranty available via the GoodWe Plus+ programme with active SEMS+ connection.

Individual DC-DC converter per module – flexibility in capacity and expansion

Unlike many battery systems where all modules must operate within a fixed voltage chain, every GoodWe ESA battery module has its own DC-DC converter. This has two practical advantages: firstly, modules of different capacities (5.0 / 6.0 / 8.0 / 9.0 kWh) can be freely combined within one system without the overall performance being limited by the smallest or weakest module. Secondly, new modules can be added to existing, older modules at a later stage without any complications – protecting the investment in the existing storage rather than having to start from scratch.

An important difference between module types concerns the charge/discharge rate: the 8.0 kWh module (8.3 kWh rated capacity) supports a C-rate of up to 1C – meaning it can be fully charged or discharged within one hour, making it particularly well-suited for high-power applications. The 6.0 and 9.0 kWh modules are designed for 0.5C. If both types are combined in one system, the lower C-rate of 0.5C applies to the overall system.

For stacking: up to 6 modules per tower are possible with wall mounting, while freestanding installations are limited to 4 modules per tower. With wall mounting, module-type-specific limits apply per group – for the 8.0 kWh module (and the 9.0 kWh module) a maximum of 2 units is permitted, while for the 5.0 kWh and 6.0 kWh modules a maximum of 3 units applies. When different capacities are mixed in one tower, the lower of the two limits applies to the entire group. A single battery tower can cover 5 to 54 kWh depending on the modules selected. For more than 6 modules in total, a second or third tower with its own GoodWe Battery Expansion Kit for ESA Series is required (max. 3 towers per system) – allowing the overall system to be expanded to up to 12 modules and 108 kWh. For larger commercial applications, up to 6 ESA systems can be operated in parallel, enabling a total storage capacity of up to 576 kWh.

6-level safety concept: From cell to emergency protection

GoodWe officially divides the ESA series safety concept into six protection levels: Cell-Level, Electrical, Structural, Monitoring-Level, System-Level and Emergency Protection. At cell level, voltage and temperature sensors continuously monitor every individual cell. Electrical protection covers overcurrent, short-circuit and reverse polarity protection as well as surge arresters. Structural protection refers to the robust IP66 housing and the mechanical securing during stacking. At monitoring level, thermal monitoring as well as PV string and insulation monitoring run continuously in the background. At system level, the AI-powered arc fault detection AFCI 3.0 provides additional protection against cable fires. In an emergency, the final level – Emergency Protection – activates the integrated aerosol fire suppression directly in the battery module. The underlying principle: if one protection level fails in an edge case, one of the remaining five will typically intervene – making the overall system significantly more robust against individual failures.
