PRODUCT DETAILS
Complete product details — specifications, images, FAQ, and downloadable resources for this VoltCrave power solution
The system provides 20.48kWh of energy storage with a 51.2V 400Ah LiFePO4 battery configuration. Four stacked battery modules form the complete storage system.
The integrated 5.5kW hybrid inverter provides 230V AC output at 50Hz. The inverter and battery modules are combined into one compact home energy storage system.
Each LiFePO4 battery module provides 51.2V 100Ah and 5.12kWh. Four modules are vertically stacked to achieve the complete 20.48kWh configuration.
The system supports a 120–450VDC MPPT photovoltaic input range. Maximum solar charging current reaches 100A for compatible residential photovoltaic systems.
Maximum charging and discharging currents are both rated at 100A. The specified constant charging voltage is 58.6VDC.
The inverter and four battery modules are integrated into a vertical floor-standing system. This configuration combines solar conversion and battery storage for residential applications.
The stacked architecture provides 20.48kWh capacity while maintaining a compact vertical footprint. Integrated caster wheels make the system easier to position during installation.
VoltCrave Power provides configurable home energy storage solutions for B2B projects. Specifications and system configurations can be customized according to customer requirements.
