    Growatt 1Ph Inverter (Hybrid or AC-Coupled) plus AXE LV Battery System

    The Growatt AXE LV Battery System is a state of the art lithium iron phosphate (LiFePO4) battery with a flexible capacity between 5kWh to 400kWh.

    The system not only meets the growing demand for residential off-grid lithium battery storage systems but is also suitable for large business and industrial scenarios.

    The battery system is modular and comes with internal plugs, requiring no extra cable connections, with all the external cables integrated onto one plug, to simplify its connection to the inverter. Each module has an internal plug connection, and the battery pack quickly connects to the inverter with a single cable harness.

    In terms of safety, there are multi-level protections from the inverter and BMS, such as cell security monitoring and balancing. Meanwhile, as a cobalt-free LFP battery, it comes with high-temperature resistance, safety, and stability as well as up to 5,000 charge cycles. The AXE LV battery system also has an expected service life of more than 10 years. Generally, it holds more advantages in terms of the TCO (total cost of ownership) for customers.

    With regards to compatibility, AXE LV battery system can be used with all Growatt’s SPF off-grid series inverters and works along with the single-phase SPH and SPA series storage inverters. At Alternergy, we are only selling the system with single-phase SPH and SPA inverters.

    For daily use and maintenance, Growatt provides a whole-system warranty including the battery system and storage inverters. Additionally, Growatt allows installers to upgrade the firmware of the battery system remotely, which can help reduce the O&M cost and improve service efficiency.
