The reason why aluminum shell products must be selected: Since the power inverter has a large power and generates a lot of heat, if the internal heat cannot be dissipated in time, it will affect the life of the components at best, and there is a risk of fire at worst.

Aluminum alloy shell has good heat dissipation characteristics and will not burn. Plastic shell products are not recommended even if fans are added to help dissipate heat, because the fan will increase noise while in use, and the shell is prone to aging and shortening its life when working.
