30kWh 15kVA Hybrid Solar Energy System with LiFePO4 Battery Storage for Grid-Connected and Off-Grid Operation
30kWh 15kVA Hybrid Solar Energy System with LiFePO4 Battery
The Voltertech BESS-30KWH-15KW-W is a compact hybrid solar energy system combining a 30kWh LiFePO4 battery with 15kVA AC output. Designed for solar energy storage, backup power and flexible grid operation, it supports both grid-connected and off-grid applications for small commercial and distributed energy projects.
30kWh Hybrid Solar Battery Storage System
The system stores electricity from compatible solar PV or the utility grid and supplies stored energy according to the site's operating strategy. It can be used to increase solar self-consumption, provide backup power and support energy management during different periods of the day.
Its integrated cabinet design combines battery storage, power conversion and communication functions in one system, helping reduce the number of separate components required during installation.

Grid-Connected and Off-Grid Operation
The BESS-30KWH-15KW-W supports both grid-connected and off-grid operating modes, allowing solar installers and system integrators to configure the system for different electricity conditions and project requirements.
For grid-connected sites, the battery can work with solar generation and utility power to improve energy utilization. In off-grid or backup applications, stored battery energy can supply supported loads when grid power is unavailable.
Optional Solar PV Input
For hybrid solar applications, PV input can be configured as an option. The system supports two PV input channels with a maximum PV configuration of 15kW + 15kW.
- MPPT operating voltage range: 200–800V
- Maximum PV voltage: 850V
- Two independent PV input channels
- Suitable for solar generation and battery storage integration
Actual PV configuration should be selected according to solar array voltage, local irradiation, load demand and overall system design.
Integrated LiFePO4 Energy Storage Cabinet
The system uses LiFePO4 battery technology and an integrated floor-standing cabinet structure. Battery storage, PCS and communication functions are arranged within one enclosure to simplify system deployment.
Air cooling provides straightforward thermal management, while IP54 protection helps protect internal equipment under suitable installation conditions.
LAN, RS485 and CAN communication interfaces support system monitoring and integration with compatible controllers and energy management equipment.
