Inverter Installed - Open Ground?
I finished installing my new Victron 250w 12v inverter. I hard-wired it with direct connections to + and - battery terminals using 9 feet of 8AWG wire. There is a connection point on the inverter for ...

It is showing OPEN GROUND because there is electrical potential between the inverter's outlet GROUND pin and its "NEUTRAL" pin. The only way to get this to not show OPEN GROUND is to connect the inverter's NEUTRAL pin to its GROUND pin. The same thing happens with a lot of the inverter generators. We build a "bonding plug" and plug it into an outlet on the generator that fixes that.
This is NOT of concern. This is not power from the utility company. The inverter, like the inverter generators, has a floating NEUTRAL and does not need to have its GROUND pin connected. Read some of the threads on this topic concerning the inverter generators. There are a lot of them. There is disagreement on whether to bond the generators with good arguments on both sides. (The only good argument on the side of bonding the generator is because some EMS units won't let power in if you don't.)
My advice is to contact the manufacturer, merely for your peace of mind, then stop testing the outlet. It is fine.
WARNING: I do not know if bonding is safe with your inverter. I do not know if bonding should be done with your inverter. I am providing this information only so you know what is causing that error message.
