Key Features and Project Advantages
A flexible high-voltage battery platform developed for system integrators, solar installers, distributors and project owners requiring scalable energy storage and simplified project deployment.
Nine Standard System Configurations
Nine battery configurations from 20.48kWh to 61.44kWh give project teams more flexibility than a fixed-capacity cabinet. The battery can be selected according to the required energy capacity, backup duration and inverter operating voltage.
Easier High-Voltage Inverter Matching
The broad system voltage range allows installers to select a battery configuration that more closely matches the DC operating window of compatible high-voltage hybrid inverters and PCS equipment.
Expandable as Project Demand Grows
Up to five complete battery systems can be integrated in parallel. This provides a practical expansion path for projects that expect future increases in electricity consumption, solar generation or backup power requirements.
Module-Level Installation and Service
Standardized 3U battery modules simplify transportation, rack assembly and system maintenance. Individual modules remain accessible, reducing the operational complexity associated with servicing a fully integrated battery cabinet.
Intelligent Battery Protection
The integrated BMS monitors battery voltage, current and temperature while providing protection against overcharge, over-discharge, overcurrent, short circuit and abnormal operating temperatures.
Stable LiFePO4 Battery Chemistry
Lithium iron phosphate chemistry provides stable thermal characteristics and long-term performance for stationary solar energy storage, daily cycling and backup power applications.
Communication for System Integration
CAN and TCP/IP communication support data exchange with compatible inverters, PCS equipment and energy management platforms. Communication matching can be confirmed before project delivery.
Project Engineering and OEM Support
GSL ENERGY supports battery configuration, inverter communication matching, system design and OEM/ODM requirements for distributors, installers, EPC contractors and energy solution providers.
Project configuration note: Battery selection should be based on the inverter or PCS voltage range, communication protocol, peak load, required backup duration and planned expansion capacity. GSL ENERGY can provide configuration support before quotation and order confirmation.
High-Voltage Battery Applications
The GSL-HV51100 can be configured for residential, commercial and off-grid projects requiring higher system voltage, modular battery capacity and future expansion.
Residential Solar Energy Storage
Store surplus rooftop solar energy for evening use, reduce grid electricity consumption and improve household solar self-consumption.
Whole-Home Backup Power
Support critical household loads during power outages when integrated with a compatible hybrid inverter and correctly designed backup circuit.
Small Commercial Energy Storage
Provide solar energy storage, peak-load support and backup power for offices, shops, workshops and other small commercial facilities.
Farms and Rural Properties
Store solar energy for irrigation controls, lighting, refrigeration, communications and essential rural electrical loads.
Hotels and Guesthouses
Improve solar utilization and maintain selected lighting, communication, security and service loads during grid interruptions.
Off-Grid and Microgrid Systems
Integrate solar generation, battery storage and compatible power conversion equipment for remote properties and local microgrids.
Is This Battery Suitable for Your Project?
This IP20 high-voltage battery is intended for protected indoor installation. Final selection should be based on the inverter voltage range, communication protocol, peak load, required backup duration and available installation space.
How to Select the Right Battery Configuration
Battery capacity alone does not determine the correct model. The system voltage, inverter operating range, load profile and required backup duration must be evaluated together.
Confirm the Inverter or PCS
Check the equipment model, DC operating voltage range, maximum battery current and supported communication protocol.
Calculate Required Energy
Identify the critical loads, operating power and required backup time to estimate the battery energy needed for the project.
Check Charge and Discharge Power
Confirm that the battery current, inverter power and expected peak load are properly matched under both grid-connected and backup operation.
Plan Future Expansion
Consider expected increases in solar capacity, operating loads or backup requirements before confirming the initial system configuration.
Information Required for System Selection
Providing complete project data allows the engineering team to recommend the correct battery voltage, module quantity and system capacity.
Frequently Asked Questions
Key information for selecting, installing and integrating the GSL-HV51100 high-voltage battery system.
What capacities are available in this battery series?
The series is available in nine nominal capacities: 20.48kWh, 25.60kWh, 30.72kWh, 35.84kWh, 40.96kWh, 46.08kWh, 51.20kWh, 56.32kWh and 61.44kWh.
How is the capacity of the system configured?
Each 3U battery module provides 5.12kWh at 51.2V and 100Ah. Four to twelve modules are connected in series to create the required system voltage and nominal capacity.
Can multiple battery systems be connected in parallel?
Yes. Up to five complete battery systems can be connected in parallel. Five GSL-R60K systems provide a combined nominal capacity of up to 307.2kWh.
Is the battery compatible with every high-voltage inverter?
No. Compatibility depends on the inverter’s DC voltage range, current limit, communication protocol and battery control strategy. The inverter or PCS model should be confirmed before ordering.
What communication interfaces are supported?
The current product specification lists CAN and TCP/IP communication. Protocol compatibility with the selected inverter, PCS or energy management platform should be confirmed during system design.
Can the battery be installed outdoors?
The system has an IP20 enclosure rating and is designed for protected indoor installation. Outdoor projects require a suitable weather-protected enclosure or equipment room.
Can the battery operate in cold climates?
The permitted discharge temperature is −20°C to 60°C. Charging is permitted from 0°C to 55°C. Temperature-controlled installation conditions may be required when the ambient temperature is below 0°C.
What warranty is provided?
The battery system is supplied with a 10-year warranty, subject to the applicable warranty conditions, approved system configuration and specified operating requirements.
