The modular concept of the Growatt apx battery system allows you a wide range of applications and flexible expansion as required. In combination with the mod xh-bp inverters, all the functionalities of the series are available to you. Between 1 and 6 high-voltage batteries can be installed within a battery tower. The battery module is a high-voltage battery that features the latest LiFePO4 technology and boasts a nominal energy of 5kWh. The body also includes a battery management system of the latest generation, which protects the battery modules from adverse conditions, and a battery base that ensures a secure stand during ground installation. As an option, a back-up box can be added for emergency power generation. It is able to provide up to 10kWh from the solar storage system in the event of a power failure.
The apx battery system contains:
- 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 Back-Up Box emergency backup power
The apx battery system demonstrates its flexible configuration options. These can be extended from 5kWh to 30kWh. The simple design makes installation and expansion very straightforward with the help of cables. Another advantage of the new storage system is that, unlike other systems, a battery cabinet is no longer required. All 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 with proven lithium iron phosphate storage technology. The LiFePO4 batteries are characterized by a long service life and a high level of safety, even at high power. In addition, the modular energy optimization ensures that the system fully utilizes the energy of each battery. In order to achieve a very 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 avoid 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 avoid overvoltages in the system
- Modular and stackable design
- Easy installation
- 10-year manufacturer's warranty
Long cycle life
The apx battery system is based on LiFePO4 chemistry without cobalt and offers a four-stage protection mechanism through a battery management system (bms), modular energy optimization, a fuse and aerosol. This ensures increased safety, reliability and a long service life. The modular energy optimization ensures that the system fully utilizes 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 that is used with the Growatt battery to protect the system from overvoltage. When the battery is started or switched on, 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 control unit of the latest generation that protects each apx battery module from adverse conditions and ensures safe and trouble-free continuous operation. It does not matter how many modules are in operation at the same time. What is important is that one bms is always used per tower. A tower consists of a minimum of 1 to 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.
