Description
The GoodWe BAT Series 14.3 kWh (model GW14.3-BAT-LV-G10) is a high-capacity, low-voltage energy storage module optimized for modern homes. Built with LiFePO₄ (LFP) cells, this battery offers excellent stability, safety, and a long lifetime.
Key Features:
-
Capacity & Energy: Rated at 14.3 kWh, with ≥ 13.8 kWh usable energy.
-
High Power Efficiency: Supports continuous charging at 0.8C and discharging at 0.94C, allowing for fast charge and strong output.
-
Cycle Life: Uses 280Ah cells, rated for up to 6,500 cycles — very durable for long-term use.
-
Parallel Expansion: Multiple units can be connected in parallel to expand storage capacity.
-
Temperature Resilience: Built-in heating technology supports stable performance even at –20°C.
-
Power Specs:
-
Max continuous charge current: 224 A
-
Max continuous discharge current: 260 A
-
Maximum output power: 12 kW normally, 13.2 kW for 10 mins, and 20 kW peak for 15 seconds.
-
-
Voltage: Nominal voltage of 51.2 V.
-
Operating Temperature:
-
Charging: 0 °C to 55 °C Discharging: –20 °C to 55 °C
-
-
Communication: Supports CAN and RS-485 for integration with inverters.
-
Protection / Enclosure: Rated IP20, meaning it’s better suited for indoor or protected installations.
-
Dimensions / Weight: ~530 × 885 × 246 mm (without base) and weighs around 125 kg.
-
Certifications / Safety:
-
IEC 62619, IEC 63056, IEC 60730. Transport: UN38.3.
-
Advantages / Use Cases:
-
Ideal for residential solar storage, especially when you want large capacity in a single unit.
-
The parallel expansion feature means you can start with one battery and add more later as your energy needs grow.
-
Great for cold climates or areas where temperature drops: the built-in heating ensures performance even at –20 °C.
-
Good for homes with high charge/discharge demand because of its high current capability.
Considerations / Challenges:
-
Indoor Installation: Because of its IP20 rating, you should install it in a protected or indoor environment — not ideal for totally exposed outdoor spots.
-
Weight: At 125 kg, it’s quite heavy — mounting and structural support need to be planned.
-
Cost: High capacity means potentially higher upfront cost; but the long cycle life can make the investment worthwhile in the long run.
-
Compatibility: Ensure your inverter supports this battery’s voltage and communication interfaces (CAN / RS-485).
