Specifications
Product Description
The GoodWe SECU A5.4-20 5.4kWh 48V LFP Battery Module is a low-voltage solution designed for residential systems and small businesses seeking to expand their self-consumption with safety, reliability, and native integration with 48 V GoodWe inverters. Its stackable modular architecture allows you to start with a single module and grow up to 32.4 kWh per string, maintaining a clean installation and full control through BMS and CAN/RS485 communications.
Main Features
- Usable energy per module: 5.4 kWh with high-safety LiFePO₄ (LFP) chemistry.
- Nominal voltage: 51.2 V (operating range 47.5–57.6 V) for 48 V LV systems.
- Nominal power per module: 2.56 kW; up to 5.12 kW with ≥2 modules in the same string.
- Integrated BMS with CAN and RS485 communications for advanced management and protection.
- Indoor stackable format (IP20) with floor or cabinet mounting.
- Simple scalability: from 1 to 6 modules per string (up to 32.4 kWh) and possibility to parallel strings via inverter/EMS.
Advantages or Benefits
- Superior safety thanks to LFP chemistry and BMS protections per cell and per rack.
- Savings and control: time-of-use strategies, self-consumption, and surplus management from SEMS.
- Professional and tidy installation with standardized wiring and communication.
- Total flexibility: expand capacity without redoing the electrical installation or technical room.
- Simple maintenance: module-level monitoring, alarms, and historical records.
- Native compatibility with GoodWe 48 V inverters for backup, smart charging, and tariff optimization.
Purpose or Applications
Ideal for residential self-consumption, small businesses, offices, and retrofit projects with 48 V inverters. It allows you to cover demand peaks, store photovoltaic surpluses, optimize tariffs with time-of-use rates, and provide basic backup when the compatible inverter allows.
