Compatible with Mainstream PV Modules
SUN2000-330KTL trumps industry compatibility standards, covering the majority of mainstream PV
modules.
Facilitate simple accessory management by smart purchases and flexible pairing, lowering costs.
Safe & Reliable
-
Smart String-level Disconnection (SSLD)
The SSLD technology enables intelligent fault detection and disconnects the string within milliseconds if an abnormal current occurs. This quick response effectively addresses issues such as internal short circuits, DC reverse polarity, and string backflow, ensuring optimal system safety.
-
Smart Connector-level Detection (SCLD)
To ensure connector wiring safety, the SCLD technology integrates a precise sensor to trigger alarms or shutdowns in case of abnormal signals or high connector temperatures, preventing fault escalation.
-
MPPT-level DC Insulation Monitoring
Our industry-first MPPT-level insulation monitoring significantly improves malfunction location accuracy sixfold, facilitating prompt safety issue resolution with lower maintenance costs.
L5-level MBUS Power Line Communication
For the first time, L5 MBUS power line communication is introduced into an inverter, realizing
further transmission distance and lower latency. Whether it's used in large-capacity arrays or
large-span power plants, communication ceases to be an issue.
The extraordinary performance of the Huawei-developed wireless MBUS chip also brings about fast
and reliable communication.
