Tip to help others. If you install an inverter and it doesn't power up or put out power this might help.

I installed my new Sungold SPH10K48SP 10kw all in one inverter today and I had no power coming out of it. Here is why :

Yes,
You have to open the terminal (unscrew it all of the way), before inserting the conductor.
Hopefully this video will help people see how they work.

On this one if you notice the one at them bottom of the screen has the plastic cover removed. I removed the screw ALL the way out of the housing on that one and it still wasn't opening like it should. Needed some kind of spring or even gravity except mounting on the wall gravity isn't helping

Laying flat it would of at least tried to release as you unscrewed it. Ive never had those kind of connectors do that before. I unscrewed them before putting the wires in.

The AC in connector worked right but the ac out (load one) is what I'm videoing there flat out wasn't working right.

The one you can't see in the video which is the first one going from left to right (L1) worked right. This held the wires in place (they are in insulation together) so it seemed like it was connected correctly. Powering up and nothing coming out. I kept looking at it and everything looked right. Tugging on the insulation it seemed firmly in there. I took needle nose pliers and went to wiggle each wire to see if anything stood out and the first wire was firmly in place but I found all the others could be moved a bit side to side (very stiff wire, solid core not mulit strand). Hmmm.

So I released the first screw and the entire bundle dropped out. Ok this was weird. So I redid it again and again the first one worked flawlessly but I couldn't get the other ones to do right. Finally put my phone under there in selfie mode allowing me to see what was happening. Figured while I was fixing it I would shoot a vid of it happening.

I backed that missing cap one out all the way and removed the cover (cap) to see what was going on.

Yeah I also learned to always check that the terminal has the tensioning device open since the wire can be inserted as you show under the closed rising style. Good idea to remind folks and your video should help explain it better for others.

Usually you can push the screw back, after loosening.
Clamp style terminals are usually floating, until tightened.

I think the AC IN messed up too the first time now that I think out it. When I connected it up the first time I had warning and it should 0 volts for L1 on that one. I couldn't find anything wrong with it so I figured maybe I pushed the wires too far in and the insulation was in the connector somewhat and I removed it some and re-tightened it or I removed it completely and redid (I can't remember for sure now) and it worked fine. Now I'm worried it's just laying on the backside of that connector and not in place right even though it reads right.....

I may pull the cover off (after de-powering of course) and double check it

I'm paranoid about this kind of stuff connection wise.

Yep that's what Ive always seen. This style is used on tons of stuff. Ive dealt with them for years in all kinds of equipment mostly in the computer field.

I prefer the pure lug, or lug with anvil attached to the screw, but ya just dont see that type much on these devices.

It's always good practice to tug on the conductor after tightening to verify.

Yep and my new method will be grabbing the wires with pliers and making sure it won't move side to side also when dealing with firm insulation wires in case its neighbors are being held in place by a few good connections
