Outstanding Safety With Huawei SUN2000-150K-MG0 Inverter

When investing in solar power systems, besides efficiency, safety is also a top priority, especially for businesses in the C&I (Commercial & Industrial) segment. Electrical problems can lead to equipment damage, production disruptions or even fire hazards, seriously affecting business operations.

Huawei SUN2000-150K-MG0 – the new generation of high-power inverters from Huawei, not only brings high efficiency but is also equipped with a series of advanced safety protection technologies, helping businesses minimize risks and operate the system efficiently and sustainably.

1. SSLD – Smart disconnect system protection

SSLD (Smart String-Level Disconnect) is a string-level smart disconnection technology that ensures the safety of the solar power system. This technology can detect DC-side problems such as reverse polarity, reverse current or short circuit inside the inverter and cut off the current immediately within milliseconds.

Highlights:

• Fast Fault Detection: SSLD integrates fault recognition algorithm, identifies problems such as reverse polarity connection, DC reverse current, short circuit and disconnects immediately.
• Comprehensive protection: Reduces the risk of equipment damage and prevents problems from spreading throughout the solar system.
• Ensure safe operation: Minimize the risk of damage, helping the system operate more stably.

2. Ground fault protection – Reduce inverter errors by 75%

Ground faults can cause current leakage, reducing system performance and posing a potential safety risk. Huawei SUN2000-150K-MG0 is equipped with advanced ground fault protection technology that can:

• Fault isolation within 15 milliseconds, ensuring stable system operation.
• Prevents faults from spreading, reducing inverter faults by more than 75% compared to conventional products.
• Increase system reliability, reduce maintenance costs and extend equipment life.

3. AFCI – Leading arc protection technology

AFCI (Arc-Fault Circuit Interrupter) is a technology that detects and extinguishes electric arcs, helping to prevent the risk of fire and explosion in solar power systems.

On Huawei SUN2000-150K-MG0 inverter, AFCI technology has been upgraded with outstanding improvements, providing higher safety:

• Detection range increased from 200m to 450m, helping to identify problems faster and more accurately.
• Arc extinguishes within 0.5 seconds, minimizing the risk of fire and explosion.

4. SCLD – Monitor connector temperature and disconnect immediately

SCLD (Smart Connector-Level Detection) is an intelligent temperature monitoring technology at AC/DC connectors, helping to detect early signs of abnormalities to prevent the risk of fire and explosion.

• Detects excessive temperature at connectors, protecting the system from short circuit and fire.
• Automatically disconnects within 0.5 seconds when temperature exceeds the allowable level, ensuring maximum safety.
