RCD, GFCI, will only protect if the power source in grounded and there is a neutral to protective earth bond.you need breakers/fuses and RCD on the AC output

Very helpful thanks,You pretty much understand. You do not want TWO different grounds from your gear to earth. Only one. If the stuff you are powering is going to be connected to house ground (Generally should not be if you unplug it) say thru a different grounding mech, you would want to use that ground only.
Yes 2 power strips with breakers would act like a breaker panel with two circuit breakers. Spend a few extra and get a couple of nicer (Ebay used?) 20A PDU's for computer gear that have a more robust breaker. I'd look at the Cyberpower rackmount units. The breaker is sized for the wiring not the source output, so with a 3KW unit you would you could push lopsided, but still protect the wiring from cooking A 20A PDU is de-rated to 16A, so more inline with your max output as well. They usually have longer pigtails, you could rig them to detach from your cart, or just trim the pigtails and stuff them into the inverter, mount it up like a generator. Use a Ferrule to combine the leads, make sure your phasing is the same in both strips.
Really, really, really bad idea.This may be common knowledge but if I was to have the EG4-3k cart setup plugged into the house wall outlet while the power is out and it running a refrigerator plugged into the power strip, the system is technically grounded thru the house outlet for AC charging cord and if the power comes back on during the night the system will start charging the battery and continue to run the fridge. Right?
This will be the likely use for this system for me. Solar will be a stand alone function not running anything off of it as during the day I have a generator to handle day time needs during power outages.

If the inverter's power input is plugged into the wall, nothing bad will happen.Really, really, really bad idea.
Really bad, no really.
Magic smoke time.

You mean plugged into the AC IN on your eg4, so power passes through?
Or are you trying to send your house electric circuits live during a powercut ?
Yes the AC in to the EG4 so power will pass thru once power is restored.You mean plugged into the AC IN on your eg4, so power passes through?

Since we were talking about grounding would it (the cart system) not be grounded this way?
Huh? There is a reason they are called suicide cords. If he's talking unplug fridge plug into cart, plug cart into fridge outlet for grid bypass, then yes, no problem. If he's talking plug a suicide cord into the outlet the fridge is plugged into not so much.If the inverter's power input is plugged into the wall, nothing bad will happen.
Input of eg4, not the output of the eg4. He's just charging from the grid, a normal configuration.Huh? There is a reason they are called suicide cords.

No suicide cord. Wall to EG4 input and cart to fridge. Sorry for the confusion. Like I said not just learning but also learning the lingo.Huh? There is a reason they are called suicide cords.

Yes, you answered my question with a much better response than how my question was phrased.So if he's putting the cart BETWEEN the outlet and the fridge, that would give you the ground, bond it to the cart. No different than A simple UPS
Having said that, ... A quality line-interactive UPS would be better for your TV's. Laptop, or anything that has a nice power supply in the front it won't matter, and the fridge won't care.I edited my post when I caught the drift but that is not what I read in my brain, sorry. You are just building a UPS with a solar input. Not a problem will work as you desire.
