GoodWe Lynx U G3 LXU 5 0-30 - LiFePO4 battery 5 kW with heating and fire extinguishing

Description GoodWe Lynx U G3 LXU 5 0-30

GoodWe Lynx U G3 LXU 5.0-30 is a low-voltage LiFePO4 energy storage device for home systems, focused on self-consumption, backup power and operation in hybrid configurations. The module has a nominal energy capacity of 5.12 kWh and a usable capacity of 5 kWh, which is a practical standard for systems with a priority on real energy return.

Fast installation: fewer unnecessary components and easier assembly

The Lynx U G3 series is designed as an “all-in-one” module: each unit already has an integrated BMS, eliminating the need for a separate power control unit (PCU). This reduces the number of connections, speeds up commissioning and simplifies system diagnostics.
Installation is provided in two typical options - wall or floor, which is convenient for a boiler room, technical room or garage.
An additional plus for the real conditions of Ukraine is IP65, which means that the housing is designed for installation in places with increased dust/humidity (in compliance with the manufacturer's instructions).

Parallel scaling: from 5 to 150 kWh

The key advantage of the Lynx U G3 is its “on-demand” scaling. The system supports parallel connection of up to 30 modules , which gives a total capacity of up to 150 kWh. This allows you to start with a single 5 kWh unit and gradually increase the energy reserve for a larger house, heat pump, frequent outages or business loads.

Inverter compatibility: which series are supported

For the LX U5.0-30 model (similar marking U-30), the official GoodWe compatibility document indicates support for a number of inverter lines. In particular, compatibility with the following series is indicated: ES, EM, SBP, ES G2, SBP G2, ES Uniq (3–6 kW and 8–12 kW), EO, ET LV.

The notes also list the requirements for firmware versions/compatibility: for U-30 it is indicated that the appropriate BMS version is required (the manufacturer separately specifies the condition for batches after April 2025) and the minimum ARM firmware versions for different inverter series.

Heating and firefighting: focus on winter operation and safety

Optional features are announced for the Lynx U G3, which are particularly useful in cold seasons and with increased safety requirements:

Heating system (heating / heating film) - for more stable operation at low temperatures. The data sheet indicates that heating is an option, and also provides temperature ranges and recommendations.
Fire extinguishing (optional, aerosol) is an additional level of protection that can be important in boiler rooms, technical rooms, or facilities with increased insurance requirements.
An important nuance: GoodWe notes in its documentation that optional features/devices can be purchased separately, so it is worth checking the package before ordering.

Practical characteristics to pay attention to when choosing

Chemistry: LiFePO4 (emphasis on thermal stability and lifespan)
Nominal voltage: 51.2 V , operating range — 43.2…58.24 V
Currents: up to 90 A charge / 100 A discharge, pulse <200 A (30 s)
Energy conversion efficiency (round-trip): ≥96%
Resource: declared over 6000 cycles under manufacturer's test conditions

Conclusion: GoodWe Lynx U G3 (LXU 5.0-30) is a good option when you need a 5 kWh LiFePO4 battery with easy installation, the ability to parallel scale up to 150 kWh, official compatibility with popular GoodWe hybrid inverters, as well as heating and aerosol fire extinguishing options to increase reliability in real operating conditions.
