If the inverter output is bonded you should never bond elsewhere. If it is not bonded internally (I’m thinking/hoping it is switched) you should not bond elsewhere than the incoming AC load center depending on the pass through / switching convention it uses.So, you didn't bond to ground anywhere on your AC Output?
You probably shouldn’t do that unless you know how it handles the N/G bond or switching.And did you jumper the AC input & output Neutrals like all the lv2424 folks do?
That isn’t a good idea, either. I remember putting a meter on a case screw and batt(-) terminal but can’t remember but I’m assuming case is bare/grn/neg to DC because I think I’d remember if it were open. ??? I’d have to check again.Finally, did you earth the inverter box to a grounding rod? If so, where on the box did you ground it?
No, I am not bonding anywhere on the AC output. No, I did not jumper the Neutrals. No, I did not ground the box (as you said, there is no provision for this)... Based on Will's videos, I'm assuming the earth ground is coming from the AC input. (In my case my main service panel). Not sure what you would do if you are not using AC input at all?Thanks for reply. I appreciate your help. So, you didn't bond to ground anywhere on your AC Output?

Actually you hit all the important points!No, I am not bonding anywhere on the AC output. No, I did not jumper the Neutrals. No, I did not ground the box (as you said, there is no provision for this)... Based on Will's videos, I'm assuming the earth ground is coming from the AC input. (In my case my main service panel). Not sure what you would do if you are not using AC input at all?
If it were open N-G something should be done. Where? At breaker panel or in the unit but not both. That’s only for 100% no grid off grid. With a generator usage you’d have to figure that out too. Because you’d only want one ground point connected to N and that at the ‘source.’Not sure what you would do if you are not using AC input at all?
You might want to but a standalone offgrid system? I don’t think you should drive a ground rod. There’s opinions on that but adding a ground rod? What does that do? Really nothing electrical. None of your power will have anything to do with earth.I'd want to bond a lug to the AOI's case, then ground it to earth via a rod.
Could you tell me why running the inverter chassis to a rod isn't beneficial?
Here you go man!not sure about that model, for any particulars
I believe OP needs to verify. @thetimboIs the inverter connected to grid?
I contacted MPP support and they told me that it does bond N/G while Inverting from battery. I wasn't sure this could be tested while the unit was "hot" (without smoking my multimeter)? So I didn't tryThere's nothing in the installation manual, that tells if it performs a N/G bond when in battery mode.
This will have to be tested, if no one else can verify it.
Just use AC Voltmeter to test the AC Voltage between G and N, G and L.I contacted MPP support and they told me that it does bond N/G while Inverting from battery. I wasn't sure this could be tested while the unit was "hot" (without smoking my multimeter)? So I didn't try
