Inverter Distribution Box

This box distribution box is designed for power measuring and fan control of up to four micro inverters. After using a larger four channel inverter to feed my solar panel to the mains (and having loads of trouble with that smart device) I switched over to four separate Grid Tie Micro Inverters.To monitor and control the cooling of these units I developped this distribution box and a Multiboard base for the inverter. ( https://makerworld.com/en/models/1234658-grid-tie-micro-inverter-base-350-for-multiboard#profileId-1254080 ) The box contains Energy meters and switches that are measured and controlled by Home Assistant.The fans can be individually controlled using the Home Assistant Automations. I have them switch on when the power of an inverter gets over 175W for more than a minute and it switches off when below 150W for more than a minute. These values are good for the 350W inverter. If you use a different power rating then you should adjust these values accordingly. The components a
