1.IP68 junction box and connector have a high degree of waterproof, effectively resist the harsh environment;
2.The junction box carries a current of 15A, ensuring high current flow through the modules;
3.Glue-spilled tank has a double-layer waterproof, cross-section with hook-shaped aluminum frame, enhanced by 10% of the mechanical load strength;
4.The module refines the current division, thus effectively reducing the loss of up to 2% due to mismatch and increasing the power output of the system;
5.Excellent salt spray resistance, anti-ammonia and anti PID, TUV, SUD certification approved;
6.Passed the 2400pa wind load and 5400pa snow load test, ensuring that the module has a stable mechanical life;
7.Modules are packaged according to color classification, to achieve consistent appearance after installation;
