Designed Around Your Energy Needs
Active Cell Balancing
Active balancing helps manage cell consistency across the battery cluster, supported by monitoring of voltage, current and insulation status.
Cableless Module Stacking
Stacking connections between battery modules simplify assembly. Ergonomic handles support lifting and positioning during installation.
Flexible Project Sizing
Choose a battery-pack configuration to match your project, with parallel clusters available for larger storage requirements.
Protection Built Into the Battery
LiFePO4 cells, multi-level fuse protection and pack-level aerosol fire suppression are included in the documented system design.
Applications for FLEX16
FLEX16 is an indoor battery system. These application illustrations show the wider site context; plan the battery location indoors in accordance with the product manual.
Frequently Asked Questions
How do I choose the right FLEX16 configuration?
Start with the required storage capacity, site load and inverter voltage range. FLEX16 has two high-voltage box versions for different battery-pack configurations; the technical team can help select the correct combination.
Can FLEX16 capacity be expanded?
The current datasheet supports up to 12 clusters in parallel. Expansion should be planned with matching cluster configurations and inverter capacity. The datasheet also sets conditions for mixing battery modules, so check the proposed additions with the technical team.
Which inverters can be used with FLEX16?
The current datasheet lists Solis, iNVT, Fox ESS, Solinteg and Growatt. Confirm the exact inverter model, firmware, communication and battery voltage configuration before ordering.
Is FLEX16 designed for outdoor installation?
FLEX16 is documented as an indoor, smart air-cooled battery system with an IP20 rating. Plan a suitable indoor location with the installation clearances and operating conditions required by the product manual.
Can FLEX16 provide backup power or work with solar?
It can be considered for solar storage and backup projects when paired with an appropriately selected inverter and control system. Required load support, transfer operation and runtime must be confirmed for the complete project.
What information is needed for a quotation?
Share the project location, load profile, target storage capacity, solar and inverter details, intended operating mode and installation layout. This helps us prepare a configuration and quotation for your project.
