Utility-scale systems incorporate comprehensive multi-level protections, including:

Multi-layer BMS and EMS protection

Insulation monitoring

Thermal runaway early warning

Automatic fire suppression

Smoke and temperature monitoring

High-voltage protection and fault isolation

These measures ensure stable and secure operation in large grid environments.

Standard models generally have a 4–8 week delivery cycle. Large-scale customized projects may vary based on configuration. We also maintain overseas warehouses in key regions (Asia–Africa and Europe) to greatly shorten delivery time.

Liquid cooling provides precise thermal control for batteries, offering several benefits:

Temperature difference maintained within < 3°C

Significantly extended battery cycle life

Improved efficiency under high-temperature environments

Lower overall system energy consumption

It is widely suitable for C&I projects and utility-scale applications.

A complete commercial and industrial (C&I) energy storage system typically includes:

PCS (Power Conversion System)

Battery cabinet / battery racks

BMS (Battery Management System)

EMS (Energy Management System)

HVAC, fire suppression, and safety systems (for containerized solutions)

The system can be flexibly configured based on project size and application needs.

Yes. All SE-F models support Bluetooth local monitoring.

SE-F5 Pro and some advanced models support Wi-Fi remote monitoring.

Users can check real-time system status and manage settings via the Deye App or web portal.

Yes. Deye residential energy storage solutions support grid-tie mode, off-grid mode, and automatic switchover.

In the event of a power outage, the system can switch to off-grid operation within milliseconds to ensure uninterrupted power supply.

Yes. The SE-F series is designed with modular scalability:

Supports up to 32 units in parallel (depending on the model).

For optimal performance, expansion should be done using battery units of the same model and batch.

The SE-F series batteries are compatible with Deye’s own low-voltage inverters, as well as major third-party inverter brands.

A detailed compatibility list is available in the product manual. If you need help verifying device compatibility, please contact us through a service ticket.

The differences among SE-F series models mainly lie in their battery capacity and scalability:

• SE-F5: 5 kWh, ideal for basic backup needs of small households.
• SE-F12: 12 kWh, a mainstream choice for medium to large homes with higher load requirements.
• SE-F16: 16 kWh, suitable for powering high-demand appliances or extended backup scenarios.

All models support modular expansion and feature the same BMS protection level, communication interfaces, and monitoring functions.

Typical causes include:

Reversed or loose communication wiring

Battery not activated in the required sequence

Firmware version mismatch

Conflicting system parameter settings (e.g., voltage range)

The general commissioning procedure includes:

Connecting the battery to the inverter

Checking the communication cables

Activating the battery

Configuring system parameters

Verifying operational status through the monitoring platform

If any error codes appear, please refer to the product manual for troubleshooting instructions.

Some models support outdoor installation, provided that the required protection levels are met, including IP rating, waterproofing, dustproofing, and sunshade protection.

It is recommended to use a compatible protective cabinet or enclosure for optimal safety.

Immediately stop using the product, disconnect the power supply, and ensure proper ventilation. Do not attempt to disassemble the battery.

Please contact professional service personnel for inspection and handling.

The system incorporates multiple protection mechanisms, including:

Overcharge / over-discharge protection

Over-temperature protection

Short-circuit protection

Active fuse protection

Cell balancing management

These features ensure long-term safe and reliable system operation.
