Their N, your L2, is bonded to ground.
Modifications are required for North American use.

And I'm pretty sure he's got no NG bond at the breaker panel. Having NG bonding screw in Growatt and NG bond at the panel would cause a short circuit through the autotransformer and trip the inverter.You don't have a N/G bond.

Not in the least just look at the wide variety of answers thrown out there from the armchair DIYers. Every response should have first asked and received more information before making their wild a** guess based on what they think they know. It's called the Dunning-Kruger Effect.First, this is DIY.
Second, it is pretty arrogant of you to assume nobody here knows anything about this sort of problem.
Many here have practical experience and more than enough education to know what they are saying. I know I wouldn't give advice in here until the OP posts back pictures and a wiring diagram so I wouldn't give a wrong answer.
I can see your point that the OP should carefully consider the advice he is given before doing things. And be double careful about testing before letting his famliy near. But it doesn't take a certified master electrician to track down an issue like this.
Helpful people offering possible solutions based off the information someone provides isn't Dunning-Kruger lol.It's called the Dunning-Kruger Effect.

Detailed pictures of each panel and device wiring would help.
Please…
Before you attempt ANY troubleshooting, get good lighting, and take detailed pictures of everything connected to the container, let us see the boxes, wires junctions everything.
We may see the issue right away, and save you a lot of headache.
Would you mind double checking my wiring please? im new to this. solar systems are relatively new to Puerto Rico and the 3 electricians I know are not able to see the problem due to their low knowledge on solar.I don't need any pictures to know what the problem is.
But that's because I am familiar with their equipment.
And 40 years in the trade , doesn't hurt.
Just a quick follow-up to my advice I offered. I fed my family working as an electrician giving me enough knowledge to know I can't walk you through this online and be 100% certain of your family's safety.
To those posting help do you feed your family doing electrical work? or is this a hobby? The OP has a right to know just how much you really know.
I'm seeing a green wire connected to a black wire with a red wire nut in that breaker panel on the lower left. Green or Green/yellow stripe is for ground.
Perhaps we should go through the whole wiring scheme device by device.
I think we could still use detailed wiring pics. There's all sorts of possibilities and people jump to conclusions especially about grounding and bonding.
Is ground bonded to neutral in your right panel? I can't tell from looking at the pic.Would you mind double checking my wiring please?

Just explain to them that those units are 240v single phase (European L, N, G). And bonding their neutral to ground. So, the transformer input has its L2 bonded.Would you mind double checking my wiring please? im new to this. solar systems are relatively new to Puerto Rico and the 3 electricians I know are not able to see the problem due to their low knowledge on solar.
See the picture for explanation.Does not have to. Please excuse my ugly drawing. Still need to figure out which wire was bonding to shipping container via 120v outlet or if there was earth ground connection to the Growatt. Need more info.

Thank you so much for this!!!Just explain to them that those units are 240v single phase (European L, N, G). And bonding their neutral to ground. So, the transformer input has its L2 bonded.
The bonding screw inside them needs to be removed. And then, the neutral from the transformer output needs to be bonded to the ground.
This is the screw that needs to be removed from each unit.
grounds are at their designated ground busbar as labeled on the right of that panel and neutrals are at their designated busbar on the left of the panel as labeled on the panel.Is ground bonded to neutral in your right panel? I can't tell from looking at the pic.
OK but what I am asking is, in the right panel, is the neutral bar connected to ground bar also knows as N/G bond? Also when you unplug that second outlet jumper from first outlet, does your shipping container still zap you or are you seeing 120V between ground and container?grounds are at their designated ground busbar as labeled on the right of that panel and neutrals are at their designated busbar on the left of the panel as labeled on the panel.
