Description  

The Growatt APX is a modular, stackable high-voltage LiFePO₄ (LFP) battery system designed for the Growatt MIN series (3800–11400TL-XH-US) grid-tie inverters. It offers flexible capacity scaling from 5 kWh up to 30 kWh, with high efficiency, safety certifications (UL 9540, CEC listed), and comes with a 10-year warranty. Perfect for residential or small commercial solar storage.

Key Features & Benefits

  • Modular & expandable: Start with a single 5 kWh module and scale to 30 kWh as needed.

  • High-Voltage architecture: Operates in a nominal high-voltage range (≈ 385 V with a broader operating window) to reduce wiring losses and maximize inverter compatibility.

  • Efficient energy optimization: Each module features built-in BMS with multiple protection levels (overvoltage, undervoltage, overcurrent, temperature, etc.).

  • Safe & certified: Certified with UL 9540 and listed in CEC (California Energy Commission) for residential energy storage systems.

  • Long-lasting chemistry: Uses cobalt-free LiFePO₄ cells for long cycle life, high thermal stability, and safety. 

  • Power & performance: Designed to work harmoniously with Growatt MIN inverters, enabling efficient energy storage integration.

  • Robust & flexible installation: IP-rated/enclosure designs suited for indoor or sheltered outdoor installations depending on unit.

  • 10-Year Warranty: Backed by manufacturer support and warranty coverage for residential/commercial deployments.

Typical Specification Highlights

Parameter Typical Value / Range
Base Module Capacity 5 kWh
Expandable System Size Up to 30 kWh (stackable modules)
Nominal Voltage ~ 385 V
Operating Voltage Window ~ 330–450 V 
Peak Output Power (per module) ~ 3.5 kW (60 s)

Usage & Compatibility Notes

  • This battery system is specifically designed to pair with Growatt MIN series (3800–11400TL-XH-US) grid-tie inverters, enabling you to add energy storage capability to existing or new solar systems.

  • When scaling up, you can connect multiple power control modules in parallel to increase total capacity and output.

  • Ensure correct input voltage matching and that inverter firmware supports high-voltage battery integration.

  • Proper ventilation, temperature control, and environmental protection are essential for optimal performance and longevity.
