Dyness Commercial ESS for C&I Energy Storage

Dyness Commercial ESS provides a powerful foundation for commercial and industrial energy strategies. Commercial energy storage systems can be used to reduce peak loads, make more efficient use of available grid connection capacity, increase PV self-consumption and store energy for use at a more suitable time. Rebor offers two complementary C&I systems: the fully integrated DH200F EnerCore (215 kWh / 100 kW) all-in-one outdoor ESS and the modular BF100-C140 (140.6 kWh) outdoor battery cabinet. Both systems use LiFePO4 battery technology, feature IP55 protection and are designed for demanding outdoor installations.

Product overview: DH200F EnerCore vs. BF100-C140

Both systems are LiFePO4-based outdoor C&I solutions with IP55 protection. The main difference is the level of integration and the system architecture: the DH200F EnerCore has an integrated PCS, while the BF100-C140 is a battery cabinet that must be combined with a compatible external PCS or inverter system.

Dyness DH200F EnerCore, 215 kWh / 100 kW all-in-one outdoor ESS

The Dyness DH200F EnerCore is an integrated industrial energy storage system for C&I applications. The system combines 215 kWh of LiFePO4 battery storage with 100 kW of bidirectional power in an IP55 outdoor enclosure. Depending on the configuration, the system can be used for peak shaving, PV self-consumption optimisation, energy management and applications with limited grid connection capacity.

Two configurations

  • DH200F-S000L00: AC integration without PV MPPT and without the STS backup functionality of the S150L01 variant.
  • DH200F-S150L01: Includes 3 MPPT trackers, up to 150 kW total PV capacity, 200–670 V DC and 50 kW per MPPT channel, plus <20 ms STS switching for the designated backup function.

Communication

The DH200F EnerCore supports Ethernet, 4G, RS485, Modbus TCP, IEC61850 and CAN for communication, monitoring and integration with higher-level energy management systems.

Fire protection

The system combines multi-sensor detection for relevant safety parameters with aerosol suppression. Depending on the configuration, Novec 1230 (Perfluorohexanone) or FM-200 are available as optional extinguishing agents. The actual fire protection configuration must be verified against the selected system version and current Dyness documentation before project planning and ordering.

Weight

The DH200F EnerCore weighs approximately 3,300 kg. The current technical documentation for the specific configuration must be used when planning transport, lifting and foundation requirements.

Scalability

For larger projects, the system specifications indicate that up to 12 units can be connected on-grid, corresponding to 2.58 MWh of nominal storage capacity. Up to 5 units are specified for off-grid applications. The exact parallel configuration must be engineered on a project-specific basis in accordance with Dyness system requirements.

⚠️ Installation by qualified professionals only. The system weighs approximately 3,300 kg and requires a foundation suitable for the system and installation location. The current Dyness installation documentation and all applicable electrical, structural and fire safety requirements at the installation site must be followed during planning and installation.

Dyness BF100-C140, 140.6 kWh LFP outdoor battery cabinet

The Dyness BF100-C140 is a 140.6 kWh LiFePO4 outdoor battery cabinet for commercial and industrial energy storage applications. With a nominal voltage of 448 V DC, integrated BMS/EMS, IP55 protection and C3 corrosion protection class, the BF100-C140 is designed for suitable outdoor installations. The BF100-C140 does not contain an integrated PCS and is therefore not a complete standalone energy storage system. Operation requires a compatible PCS or inverter system approved by Dyness for the specific system configuration.

1. What applications are commercial energy storage systems suitable for?

Commercial energy storage systems can be used for applications including peak shaving, increasing PV self-consumption, time-based charging and discharging, and managing sites with limited grid connection capacity. Which functions are technically and economically suitable depends on the load profile, grid connection, electricity tariff, PV system and selected system configuration.

2. How can a Dyness Commercial ESS help optimise energy costs?

An energy storage system can reduce peak loads, store surplus PV generation and charge or discharge energy according to the required operating strategy. The actual financial benefit depends on the site's load profile, electricity tariffs, grid connection, PV generation and EMS strategy. The DH200F EnerCore S150L01 variant additionally provides direct PV integration of up to 150 kW through three MPPT channels and STS switching of <20 ms.

3. Are Dyness systems scalable for larger C&I projects?

According to the system specifications, the DH200F EnerCore supports AC parallel connection of up to 12 units on-grid, corresponding to 2.58 MWh of nominal storage capacity, and up to 5 units for off-grid configurations. For the BF100-C140, scalability must be assessed together with the external PCS and the specific DC system architecture. The maximum permitted configuration must be determined from the current Dyness system documentation.

4. What is the difference between the DH200F EnerCore and the BF100-C140?

The DH200F EnerCore (215 kWh / 100 kW) is an integrated all-in-one system with its own PCS and EMS. The S150L01 variant additionally provides three PV MPPT channels with up to 150 kW total PV capacity and STS switching of <20 ms. The BF100-C140 (140.6 kWh), by contrast, is an outdoor battery cabinet with a nominal voltage of 448 V DC and an operating voltage range of 406–504 V DC. It requires a compatible external PCS or inverter system. The two products therefore differ primarily in system architecture, integration level, storage capacity and the external components required.

5. Which PCS or inverter systems are compatible with the BF100-C140?

The Dyness BF100-C140 is a high-voltage DC battery cabinet with a nominal voltage of 448 V and an operating range of 406–504 V DC. A matching voltage range alone does not confirm system compatibility. Before system design, the exact PCS or inverter model, communication interface, system parameters, firmware and official approval for use with the BF100-C140 must be verified. The presence of a CAN or RS485 interface alone is not proof of compatibility. Connection to 48 V low-voltage battery inverters or conventional PV string inverters without a suitable battery interface is not permitted.

6. What safety features do the Dyness C&I systems provide?

Both systems use LiFePO4 battery technology and feature IP55 enclosures. The DH200F EnerCore combines multi-sensor detection with aerosol suppression, with additional extinguishing-agent options depending on the selected configuration. The BF100-C140 includes multiple safety and detection functions, including aerosol suppression, a water spray system, multi-sensor detection, water ingress detection, ventilation and audible/visual alarms. These integrated safety functions do not replace project-specific fire safety and installation planning in accordance with manufacturer documentation and applicable local requirements.

7. What are the installation requirements for Dyness C&I systems?

The systems must be designed and installed by appropriately qualified professionals. For the BF100-C140, factors including the approximately 1,650 kg system weight, foundation requirements, specified service and safety clearances, and site drainage must be taken into account. The DH200F EnerCore weighs approximately 3,300 kg. For both systems, the current manufacturer documentation is authoritative for transport, foundation design, electrical connections, clearances and fire safety. All applicable legal and technical requirements at the installation location must also be observed.
