If you want to replace that inverter, you need to remove the entire chassis. This of course exposes the lone service worker to high voltage DC. The unit looks like it can be separated but they tell me it cannot be. This reminds me of the Fronius IG series inverter. I argued with Fronius for an entire day about how idiotic it was to propose tarping panels to protect service workers. I submit that an inverter without a separatable disconnect requires an outboard DC disconnect or it is not viable. The DC disconnect adds cost and clutter to any install.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'>Solectria has an outboard, remotely activated disconnect. I was hoping to get my hands on one at a recent local sales seminar Solectria held, but the goofball presenting the seminar did not bother bringing one ( I can call him a goof ball because he has since left Solectria. I would not otherwise call anyone at a manufacturer a name, they are all good people doing the best job they can with the products they are hired to represent). Anyway, before I bid another Solectria I will price compare with the cost of the remote disconnect included. I won’t install one until I have touched the device to verify it is suitable.<o:p></o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'>I am taking a poll: Which GT inverters have included, separatable DC disconnects?

The bracket is not wide enough to span two studs in most cases, so if you are mounting it inside, you cannot mount it on a plywood backboard and you cannot mount it on the exterior of a wood-sheeted structure. It is not unlikely that if any trees are near your inverter, a few leaves will likely become lodged behind the inverter over time and they then could burst into flames. To me this inverter heating seems very limiting.
