I recommend Victron and Outback now.

I really don't know if my Outback gets hot. Guess I'll go check, but I'm thinking since it's 48v I may be a bit safer not pumping hundreds of amps through it, since that's where heat usually comes from. Resistance.

The Magnum is fine. That is until after a heavy load for an hour or two. Then the cooling fans are running, flat out. As soon as the fans, which are 120 volt, no longer receive power from the inverter, they stop. No fans, no cooling. End result extreme heat inside the case.

If they had used dc fans, or dc control circuits to dc fans it would be a superior design.

The unit I have weighs 47 lbs.

But the scorch marks/ cooked inverter happened because you turned it off before it cooled down not realizing the fans would stop not having 120v power. Poor design possibly but I believe it wasn't designed to be used like a light bulb.

I've been using the exact Magnum inverter as you with the only difference is I never have turned it off except 2 times in over 5.5 years and I do pull heavy loads at times for hours, no scorch marks or cooked unit yet. It does throw some heat. ;)
