Description

Growatt APX 25.0M-S3 High-Voltage Battery Storage stores surplus solar power from your photovoltaic system and delivers it exactly when you need it. With a storage capacity of 25 kWh, this battery storage system provides ample reserve for families with high electricity demand and can be flexibly integrated into single-phase or three-phase systems.

Your Advantages at a Glance

High capacity: 25 kWh of usable energy increases your self-consumption and independence from the public grid.
Safe LFP technology: The cobalt-free lithium iron phosphate cells are known for their exceptional durability and thermal stability.
Easy installation: The stackable design without additional wiring simplifies assembly – choose between floor or wall mounting.
Flexible & robust: Compatible with single-phase and three-phase systems, IP66 protection rating, and a wide temperature range of –20 °C to 55 °C.

The System in Detail

The Power Module (Master Module)

The Growatt APX 5.0M-B3 power module forms the heart of the battery storage system. It controls the entire system, handles energy management at the module level, and is compatible with single-phase and three-phase systems. Via the CAN/RS485 communication interfaces, the master module continuously monitors state of charge (SOC), system voltage, current, as well as cell and PCBA temperatures, ensuring safe operation.

The Battery Modules

Four Growatt APX 5.0P-B3 battery modules, each with 5 kWh of rated energy, combine with the master module to form the total capacity of 25 kWh. Each battery module uses cobalt-free lithium iron phosphate (LFP) cells, known for their long service life and high safety. Thanks to the stackable design, the Growatt battery storage system can be expanded with minimal tools and without complex wiring – allowing you to make optimal use of your solar power throughout the day.
