Magnum Inverter

i like it,,, looks real good and well thought out
should be NO problems

Ok here are some pictures what do you think. There is the 6" air space all around and I will install guards for the r side and bottom



sub Panel fuse and cutoff

Now on to the wiring unless there is a problem anyone sees

Actually, it should not have a shutoff. Most are wired directly to the batteries. That way the charger will work any time that you are connected to shore power.

My Magnum cannot be turned off and will drain the battery to 50 percent in a month. Therefore I added a shutoff switch.

x2 on a shutoff. great for storage as well as maintenance to the batteries or inverter... less exciting that just pulling the fuse / cable and getting that nice arc when you install it again as the capacitors recharge.

I am putting a shutoff in because it is easier to turn a knob than having sparks

My Magnum is mounted upside down from the factory and works just fine.

Page 12 of the owners manual has depictions of the Magnum's vents and the mounting orientations that are suggested. I also read that it should not be directly attached to a combustible surface and that is also wood.

On the big low frequency inverters, orientation is as much about the weight of that big, honkin' transformer, and how it is supported in the unit as anything.

Sam,

Assuming his is the same as mine intake and exhaust are on the sides where the 6" clearance is needed and fans control the flow. There are 4 approved and I'm sure engineered orientations.

I still don't understand.

Hot air flows from bottom to top.
If the intake and exhaust are on opposite sides, then mounting it "upside down" does nothing.

If the intake is NOT opposite the exhaust, then the exhaust port NEEDS to stay on top.....because that is the way the best airflow was engineered.

Now, can you get away with changing the orientation ?
Maybe if there still is an opening on the top.
Rotating it so that the now top side is the solid one without a vent is NOT a good thing to do.
