Inverter Sub Panel

I have installed solar panels with charger and a Magnum pure sine inverter/charger with a sub-panel to run a separate 15 amp circuit for tv, computers and charging needs. It is not tied into the regular house circuits. My question is this, The sub panel I purchased has only 1 bar without a separate ground bar like in the main panel. That being the case, can I combine the ground and the neutral to the single bar?

Second question, the inverter has a pass thru a/c charger that kicks in when on shore or gen set power. What about he existing converter, do I just disconnect it?

Thank you in advance for any help.

Thank you all for the advice.

The neutral buss must be isolated from the ground. Leaving the bonding screw out isolates the buss making it an isolated neutral.
I would not recommend splicing the neutrals, but yes, you can.
I would splice the grounds and run pigtail to the box.

Bud, as it turns out the green bonding screw is set up to install in the neutral buss if required. I am planning on grounding the box utilizing the bonding screw (it is designed for it) do I need to install a new neutral buss or can I connect the a/c in neutral and a/c out neutral together with wire nut in the box?

Do not combine them. Go and pick up a ground bar at your local hardware store.
Make sure the one in your sub-panel does not have a bonding screw installed in the neutral buss.

Yes. Yank or switch its 120v supply.

In case you haven't started this sub-panel job, many of us find it's much easier to plug the shore cord into the inverter or hard-wire it to the main panel. Makes things much easier. And if you sell the rig you don't have all that explaining to do.

No- make sure the neutral bar is isolated from the case (insulated) and just add a ground bar- there is usually a place for one.
