An enclosure design is disclosed to accommodate and support the unique features and capabilities of the Smart and Scalable Power Inverters or Mini-Inverters that have multiple input channels to easily connect to multiple solar PV panels, invert the DC power to AC power, and daisy chain together to generate AC power to feed the power grid or supply power to electrical devices. Further disclosed is a message system using LEDs (light-emitting diodes) mounted on the enclosure to indicate the system status and the status of each input channel of the Smart and Scalable Mini-Inverters.
