The installation ambient temperature of the combiner box should be between -25℃ and +60℃, and the relative humidity should be between 0 and 95%. All electrical connections generate heat due to I²R losses—the power dissipated is proportional to the current squared times the resistance. The question. . A good Inverter Combiner Box should have a high temperature rating, typically around 60°C to 85°C. Key features include: Reverse current protection is essential when module shading or mismatched strings cause imbalance.
