Mains Charging Current | 100A | 120A | Mains charging current increased by 20% |
Maximum Bypass Overload Current | 40A | 40A | — |
Maximum PV Input Power | 6000W | 9000W | Maximum PV input power increased by 50% |
Number of PV Inputs | 1 Channel | 1 Channel | — |
Maximum PV Input Current | 22A | 27A | Maximum PV input current increased by 22.7% |
Maximum PV Charging Current | 100A | 120A | Maximum PV charging current increased by 20% |
Number of PV Inputs | 1 Channel | 1 Channel | — |
MPPT Tracking Range | 120-500V | 60-500V | MPPT tracking range voltage is wider, as low as 60V |
MPPT Start-up Voltage | 120V | 80V | MPPT start-up voltage is lower |
In addition, the PRO version is also equipped with dual output function and PV reverse connection protection as standard, further improving the flexibility and safety of the system, allowing users to use it with confidence even in complex power consumption scenarios.
II. Three Innovative Forms: Unlocking Full-Scenario Applications
To meet the differentiated needs of different users, Demuda has innovatively launched three core versions based on the DFHY6.2KW-EU PRO: installment payment, IP54 waterproof and dustproof, and built-in circuit breaker, realizing the transformation from "single product" to "solution".
1. Installment Payment Version: Making Green Energy Accessible
For many household and small industrial and commercial users, paying the full price for PV energy storage equipment at one time is often a threshold. The launch of the installment payment version has completely broken this barrier:
• Low Threshold Entry: Users only need to pay a low down payment of 10%-30% to install and use.
• Flexible Repayment: Supports 1-12 installments, with monthly payments as low as 100 yuan, making it easy and stress-free.
• Loan Repayment with Power Generation: After installation, electricity bills can be saved through photovoltaic power generation, and the power generation income can cover the monthly installment payment, realizing "zero-cost" enjoyment of green energy.
This model not only reduces the financial pressure on users, but also effectively reaches potential users in the sinking market with limited budgets, accelerating the popularization of PV energy storage technology.
2. IP54 Waterproof and Dustproof Version: Fearless of Harsh Working Conditions
For dusty, humid semi-outdoor environments such as roofs, balconies, garages and small factories, Demuda has launched the PRO version with IP54 protection level:
• Level 5 Dustproof: Effectively blocks most dust from entering, protecting core components such as inverters and MPPT from stable operation.
• Level 4 Waterproof: Resists light rain, splashes, environmental condensation and cleaning water sprinkling, adapting to complex outdoor scenarios.
• Full-Dimensional Protection: Through professional sealing technology and anti-corrosion hardware, it fundamentally reduces equipment loss, extends service life, and reduces the repair rate caused by environmental factors.
3. Circuit Breaker Version: Dual Upgrade of Safety and Operation and Maintenance Efficiency
The PRO version with built-in circuit breaker has raised safety protection and operation and maintenance convenience to a new level:
• Millisecond-Level Response: Quickly cuts off in case of circuit overload or short circuit, eliminating the risk of fire and electric shock from the root.
• Quick Fault Location: The circuit breaker status is visualized, and the fault point can be directly judged in case of failure, greatly shortening the operation and maintenance time.
• No Additional Cost: The circuit breaker is pre-installed at the factory, so users do not need to purchase and install it separately, saving supporting costs and construction time.
• Adapt to Complex Scenarios: It can stably carry large current output and protect equipment in extreme environments such as power grid fluctuations and lightning surges.
III. Conclusion: More Than Upgrade, It's Empowerment
The Demuda DFHY6.2KW-EU PRO upgraded version is not only an optimization of the performance of the previous generation product, but also an in-depth insight into and response to user needs. With the improvement of performance and the support of three innovative forms, it provides more flexible, reliable and cost-effective PV energy storage solutions for users with different budgets and scenarios.
Whether it is household users pursuing efficient power generation, industrial and commercial owners who need to cope with harsh environments, or potential consumers who hope to reduce the financial threshold, the DFHY6.2KW-EU PRO can be the ideal choice to start a green energy life. Demuda will continue to innovate, empower a sustainable future with technology, and allow every family to easily embrace clean energy.
