Hello Tecnodave,
Your analysis is very helpful. I actually purchased the Fution Power Wall on Amazon last year and installed it on a 45 ft boat. Our mechanics/electrician used a 110/240 transformer to make it work. The power in is just taken from the grid directly for 240V. Because it is on a boat and is not being charged and discharged daily, it works for us so far. But we do have minor issues. I wonder whether you can offer your insights since you already took one apart. I will take all the precautions since I know this machine is not safe or UL listed. So I will not leave it being charged unattended and has to be vigilant on what is going on with the machine. Thank you.

First look under the right bottom of the cabinet and you will see a white handled circuit breaker there labeled DC BREAKER check the label on that breaker, if it is the same as mine rated for 230 volts AC and NO rating for DC.
AC breakers are not designed for DC and will arc and burst into flames on a overload situation. This is extremely dangerous as all the power of the batteries will be shorted to arc in that breaker......A plain old fast blow fuse would be much better but a much better solution is a true DC rated breaker such as the MidNite Solar MNDC breaker which is really a Carlingswitch D series breaker, <EDIT Ancor Marine also is a Carlingswitch breaker rebranded > Just be sure rated for 72 volts or so....and rated for “DC”.....off shore sh** probably does not have a high enough rating. Many are 12/24 volt only.
OK That is what could burn you down.......change that breaker
On to the cells......I have never seen cells like this in a consumer product...They are aluminized plastic foil pouches, with no outer housing. I have pulled open a few dead LFP cells and they had several pouches like these but they were encased, in a glued plastic housing that can contain a ruptured cell, these are just the pouches with no containment.
Someone else posted in another thread that i have on this unit that speaks of a burst cell and the release of toxic gasses in a housing situation.
Not Good.......toxic gasses while you sleep anyone?
The BMS in the unit is the cheapest, wimpiest, Daly unit that i have ever seen, characters all in chinese
Do i wanna trust that?....
I scrapped my unit and will use the cells reconfigured for 24 volt to use with my existing system using better BMS’s and my existing charge controllers and inverter/charger.
