1. If optimizers and PV modules are installed close to the rooftop (for example, color steel tile
rooftop), ensure that the optimizers are well ventilated. It is recommended that the ambient

optimizers may shut down for overtemperature protection. After the operating temperature
decreases, the optimizer automatically recovers with no risk of damage.
