Dyness DH200F Cabinet with STS

The Dyness DH200F is a fully integrated, cabinet-style energy storage system designed specifically for commercial and industrial (C&I) applications. The system combines the battery, BMS, inverter (PCS/DCAC), and optional STS (automatic transfer switch) into a single unit, providing a complete, ready-to-install solution.

What is it used for?

The DH200F is designed for projects involving not just energy storage, but complex energy usage.

Typical applications:

• peak shaving
• load shifting
• backup power for critical consumers
• integration of PV + ESS systems
• industrial and commercial energy optimization

With the STS option, the system can quickly switch between grid and island mode, which is particularly important for critical infrastructure.

How does it work?

The system is based on a high-voltage (HV) LiFePO₄ battery, which provides approximately 215 kWh of capacity. The energy stored on the DC side is converted to AC by the built-in inverter and supplied to consumers or the grid.

The central component of the system is the BMS, which continuously monitors the battery’s status and ensures safe operation. The system is also capable of handling multiple PV inputs (via optional DC/DC modules), allowing it to be directly integrated with a solar panel system .

Technical and System-Level Benefits

One of the DH200F’s biggest advantages is its “all-in-one” design. No separate battery, inverter, or controller is needed—everything comes in a single unit, which significantly simplifies installation.

The system:

• has a capacity of approx. 215 kWh
• provides 100 kW of AC power
• operates as a three-phase system
• can be used in both off-grid and on-grid modes

The built-in fire protection system and multi-level protection enhance operational safety, which is a fundamental requirement in industrial environments.

Important to know

This system is not a residential product. It falls into the industrial category in terms of both size (~3 tons) and power output, so a suitable location, infrastructure, and planning are required.

The configuration (e.g., PV connection, STS, DC-DC modules) may be project-specific, so it must always be considered as part of a system, not as a standalone product.

SOLARKIT Reviews

The DH200F is a typical “boxed” BESS solution, which is becoming increasingly common on the market. Its biggest advantage is that the system does not need to be assembled from separate components—this saves time, planning, and reduces the risk of errors.

The STS option is particularly valuable in locations where uninterrupted power supply is critical. In such cases, the system can switch between grid and island mode virtually seamlessly.

Overall, this is a robust, industrial-grade energy storage solution well-suited for medium and large C&I projects where stability and energy management are critical from a business perspective.
