My guess is not. I would be very surprised if the gfi would even hold with that inverter.

If it were outside as you say, would the extreme cold
affect it, we only use the cottage on weekends etc. and
the temp. drops as low as -40C from time to time.

It's interesting how Morningstar can get things to run so cool and without cans, whether it be their Sure Sine inverter, or their MPPT, TS-60 controller. They prove it can be done. Meanwhile my MX-60's fan is blowing hot air.

It's all about having enough heat sink area and contact surface with components capable of operating at a given thermal level. Or in English, getting the heat out of the semiconductors. The closer the components are run to their maximum current, the more heat they generate. Run 80 Amp components at 40 Amps, less heat. Run them at 80 Amps, more heat. You can only remove so much of that so fast without a fan. How much depends on the surface area of the component in contact with the heat sink (conductance) and the thermal difference between that and ambient. Put a fan in the design and suddenly you can lose a lot more heat very quickly. That's why so many companies do that.
Any minute now an engineer is going to come in to this thread and go into great detail about what I've just alluded to.
