lp68 Junction Box and Connector have a high degree of waterproof, effectivelyresist the harsh environment
The junction box carries a current of 15A, ensuring high current flow throughthe modules
Glue-spilled tank has a doubletayer waterproof, cross-section with hook-shapedaluminum frame.enhanced by 10% of the mechanical load strength
The module refines the current division, thus effectively reducing the loss of up to2% due to mismatch and increasing the power output of the system
resistanceExcellent salt spray ,anti-ammonia and anti PID, TUV, SUD certificationapproved
Passed the 2400pa wind load and 5400pa snow load test, ensuring that themodule has a stable mechanical life
Modules are packaed accordina to color classification, to achieve consistentappearance after installation
