Thanks. I was able to order one. VERY hard to find item. Hard to believe it’s not included with the inverter.

So now I’m searching for the fuse holder for the output ac line on the inverter. Can anyone point me in the right direction to a fuse holder that I can connect 12 AWG wire to? It’s only a 3 amp fuse but the instructions say to use #12 wire so I was hoping to find one that would work.

For lower voltage wiring stuff, I rely on DEL CITY in Milwaukee. Bruce Roe

But the 3A fuse is in the 120V AC output. Can't use a cheap automotive 32V rated fuseholder

Right, choose the part rated for the ap. Del City is great for battery stuff, but they do have
some high voltage fuse stuff. Bruce Roe

The inverter came today. Testing resistance between the 12v input negative lug and the ground lug shows open/no circuit. Reverse leads same result. I would say that this inverter weighs as much as a half dozen or so of the units from the big box outfits.

The sure sine is a beast of an inverter. It needs that 100A input fuse to be able to deliver a surge without blowing the fuse.
And yes, the 3A 240V fuseholder is a odd duck tor try to find, they are about $1 in bulk, why they could not include one in the box, and instead risk folks not using one, or using a 32V one from the auto parts store is beyond me.

SO for grounding I’ll have a relay controlled conductor joining one of the inverter outputs to the neutral in the panel. That should do it.
