User-focused benefits:

• Optimized string-level energy output

• Extended daily operating hours

• Enhanced compatibility with high-power PV modules

• Increased overall kWh production and ROI

Cost-Effective Operations

Smart functions to lower BOS

The Q-at-night function reduces unnecessary reactive power consumption, saving on operational costs. Power line communication (PLC) simplifies wiring and reduces installation expenses, while intelligent IV curve monitoring supports proactive O&M to prevent downtime.

Operational advantages:

• Reduced labor and wiring costs

• Lower operational expenses

• Improved energy efficiency

• Predictive system maintenance

Robust Grid Support

Stable operation in challenging conditions

SG350HX-US maintains SCR ≥ 1.15, ensuring stable output in extremely weak grid areas. Reactive power responds in less than 30ms, and the inverter is fully compliant with North American and global grid codes.

Benefits:

• Stable energy delivery in weak or unstable grids

• Rapid reactive power adjustment

• Reduced curtailment and system interruptions

• Compliance with international and North American standards

Proven Safety and Reliability

Continuous protection for large-scale PV

The inverter supports 2 strings per MPPT without risk of reverse connection. 24-hour real-time AC and DC insulation monitoring ensures safe operation while protecting both personnel and equipment.

Key advantages:

• Continuous electrical insulation monitoring

• Prevention of wiring errors and faults

• Reduced fire and electrical hazards

• Long-term system reliability
