Growatt APX 98034-P2 + Base – Power Module for High-Voltage Energy Storage

Essential foundation for Growatt APX HV battery systems – scalable from 5 to 30 kWh

The Growatt APX 98034-P2 + Base bundle includes the core power module (BMS) and the battery base platform, forming the intelligent heart and physical foundation of Growatt’s modular high-voltage APX battery system. This configuration is designed for integration with Growatt MID 11-30KTL3-XH inverters and supports a total battery capacity between 5 and 30 kWh, depending on the number of APX 5.0P-B1 battery modules used.

Power Module (APX 98034-P2) – Intelligent System Control
