Taking the cooling into consideration, today I start looking at how I plan to move the DC isolator and on/off switch out from under the unit, without making any structual modification to keep the warranty. I want the new elctrical cabinet designed specifically for the this inverter to bolt directly to the bottom. I will get it built at a local panel builder who is certified to build electrical panels.

If I fit a DC isolator into the elctrical cabinet mounted below the inverter, there will be no need to have one under the unit.

Someone said to me that customer dont want to spend money on the electrical par tof the install, the way I see it, if you have have taken the step to piss R 150 k against the wall what another R20k to make it look good and be functional., with emnough space to add more circuits and even the equipment for the EV charger, smart devices and all the otehr stuff people are adding to their properties. The old days of those silly 1 tier DB are like fax machines.
