FAQs

 

Is the GoodWe UT series compatible with the latest 210mm high-power solar modules?
Yes. The UT series supports a maximum input current of 20A per string, making it fully compatible with ultra-high power 600W+ (210mm) bifacial modules, preventing current clipping and maximizing system power output.
How does this inverter help in reducing the Levelized Cost of Energy (LCOE)?
It reduces LCOE through three pillars: 1) 1500V high-voltage design to reduce DC cabling costs; 2) HPLC communication to save communication wiring; 3) Integrated reactive power compensation at night to save equipment investment (SVG).
Can these inverters be installed in coastal areas with high salt spray?
Absolutely. The unit features IP66 ingress protection and an optional C5-level anti-corrosion treatment, providing superior resistance to salt spray, humidity, and harsh chemical environments typical of coastal PV plants.
What is the advantage of having 15 MPPTs for a 350kW inverter?
More MPPTs allow for finer granularity in tracking. This significantly reduces losses caused by string mismatch, partial shading, or complex terrain
Does the inverter support PID protection for the solar panels?
Yes, it features integrated Anti-PID and PID Recovery functions. It can apply a reverse voltage at night to repair panels affected by Potential Induced Degradation, maintaining the generation efficiency of your module assets.
What communication methods are supported for remote monitoring?
We offer flexible communication options including RS485, WiFi, 4G, and PLC (Power Line Communication). Buyers can monitor real-time data at the string level via GoodWe's SEMS portal or mobile app.
What safety protections are built into the system?
The UT series includes comprehensive protection: DC/AC Type II Surge Protection (SPD), DC Reverse Polarity Protection, Short Circuit Protection, and optional AFCI 2.0 for arc fault detection to prevent fire hazards.
What certifications does the UT series hold for international grid connection?
It is fully compliant with major international standards including IEC 62109, IEC 61727, CE (LVD/EMC), and country-specific grid codes like G99 (UK), VDE 4110 (Germany), and SASO, ensuring smooth grid-tie approval globally.
