Growatt APX 5kWh battery system with backup box and BMS P2 for MOD-XH BP inverters

The modular concept of the Growatt APX battery system allows you to use it in a variety of ways and expand it flexibly as needed. When combined with MOD XH-BP inverters, you have access to all the features of the series. Between 1 and 6 high-voltage batteries can be installed within a battery tower. The battery module is a high-voltage battery featuring the latest LiFePO4 technology and boasting a nominal energy of 5kWh. The design also includes a latest-generation battery management system, which protects the battery modules from adverse conditions, and a battery base that ensures a secure footing for floor installation. A back-up box can be added as an option for emergency power generation. In the event of a power failure, it is capable of providing up to 10kWh from the solar storage system.

The APX battery system includes:

• APX 5.0P-B1 high-voltage battery 5kWh LiFePO4 (1-6x depending on selection)
• APX 98034-P2 power module BMS
• APX battery base high-voltage battery
• Optional: SYN 50 XH 30 backup box emergency power supply

The APX battery system demonstrates its flexible configuration options here. These can be expanded from 5kWh to 30kWh. Thanks to its simple design, installation and expansion are very straightforward with the aid of cables. Another advance of the new storage system is that, unlike other systems, it no longer requires a battery cabinetall you need is the corresponding battery base, which is included with this storage system. The APX series supports the combination of mixed battery packs from new and old batches, as well as different capacities.

APX 5.0P-B1 high-voltage battery

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

The APX high-voltage battery:

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

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 aerosol. This ensures increased safety, reliability, and a long service life. Modular energy optimization ensures that the system makes full use of the energy of each individual battery. Regardless of whether the solar system is grid-connected or stand-alone, Growatt storage offers several advantages over typical lead-acid batteries and other lithium technologies.

Soft start to protect the system

The soft start mechanism is a protective function used in the Growatt battery to protect the system from power surges. When starting or switching on the battery, the power 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.

Battery management system

The new Growatt APX 98034-P2 battery management system (MPN 98034-P2) is a latest-generation control unit that protects every APX battery module from adverse conditions, ensuring safe and trouble-free continuous operation. It does not matter how many modules are in operation at the same time. It is important that one BMS is always used per tower. A tower consists of a minimum of 1 and a maximum of 6 Growatt APX 5.0P-B1 5kWh high-voltage battery modules, which can result in a storage capacity of 5-30 kWh.
