Growatt APX 5.0P-B1 High-voltage battery 5kWh LiFePO4

The APX 5.0P-B1 battery module from Growatt (MPN APX 5.0P-B1) is a high-voltage battery that utilizes proven lithium iron phosphate storage technology. LiFePO4 batteries are characterized by a long service life and a high level of safety, even at high power output. In addition, modular energy optimization ensures that the system fully utilizes the energy of each battery. To achieve highly flexible system configuration, old and new battery batches, as well as batteries with different capacities, can be mixed and connected. A soft-start function is used to prevent overvoltage in the system.

The APX series is also compatible with the new inverter series featuring a backup function: MOD-XH BP

The APX High-Voltage Battery:

• Flexible capacity options up to 30 kWh
• Cobalt-free LiFePO4 storage technology
• 90% depth of discharge (DoD)
• Active protection at the BMS level
• Integrated modular energy optimization
• Supports the combination of new and old battery modules in a single system
• Soft start to prevent overvoltage in the system
• Modular and stackable design
• Easy installation

The APX Battery System

Thanks to its modular design, the APX system is flexible and can be expanded as needed. A battery tower can be configured with a minimum of one and a maximum of six storage modules. One power module is required per tower for operation. You can choose between the APX 98020-P1 and the APX 98034-P2. This must be purchased separately. The BMS must be purchased separately, and an additional base is required for floor mounting.

Flexible Expansion

The APX battery system from Growatt demonstrates its flexible configuration options here. These can be expanded from 5 kWh up to 30 kWh. Thanks to its simple and modular design, installation and expansion are very straightforward using cables. Another advantage of the new storage system is that, unlike other systems, a battery cabinet is no longer required. Only a battery base is needed to ensure stability. The APX series supports the combination of mixed battery packs from new and old batches, as well as different capacities.

High Cycle Life

The APX battery system uses cobalt-free LiFePO4 chemistry and offers a four-stage protection mechanism consisting of a battery management system (BMS), modular energy optimization, a fuse, and an aerosol. This ensures enhanced safety, reliability, and a long service life. Modular energy optimization ensures that the system fully utilizes the energy of each individual battery. Regardless of whether the solar system is grid-tied or off-grid, the Growatt storage system offers several advantages over typical lead-acid batteries and other lithium technologies.

Soft Start for System Protection

The soft-start mechanism is a protective feature used in the Growatt battery to safeguard the system against overvoltage. When starting or powering on the battery, the current supply is gradually increased to protect the system from damage that could be caused by a sudden voltage spike. This ensures smooth and safe operation of the battery system.
