F01 fault DC Inversed failure on 2 x 5kw inverters in parallel

Any ideas
Follow up on the problem, i decided to start at the bottom and work upto the inverters.
The consumer unit had the neutral cable from the inverters ac supply loose, literally fell out when I touched it.
Fixed that problem. And followed the powering of procedure for the inverters and batteries. Still wouldn’t turn on, when the AC is turned back on the second slave inverter would power up the lcd screen and you assume it’s on however the blue light is not illuminated the side power switch, as soon as that was turned on,
The master inverter recognise it and everything went back to normal. It’s been running okay since this afternoon now fingers crossed it was just the loose neutral cable. Please be extremely careful if you decide to investigate this.
