Cheers for the link.@Andy6ft4Tall think this is the same inverter, the shipping seems to be free in the UK. It came up as £0.00 in my basket

Yes i'v spoken to Vevor and they have stock in their Czech warehouse. Vevor don't have the best reputation for customer services but the same can be said for many retailers on Amazon and eBay. At least in the UK we have an option to ask the bank to claw back any card payment in full if a card purchase is faulty or not as described. It's a faff to do a clawback with a bank because you usually have to go into a branch to start a clawback instead of doing banking services online.
I'v spent the last couple of days online, picking up bits of information from different sellers about this LF inverter charger.
From one seller you can buy this unit with an additional On/Off switch panel with 3 LED's to show what mode the inverter is in.
Originally you could buy a complete LCD control panel with a 5 meter extension lead but that seems to have been fazed out (probably due to the 5x increase in price of chips in the past 18 months & the US sanctions on chips being supplied to China)
Most retailers cannot supply either type of remote control panel.
Apparently this inverter is an upgraded version of the W7 inverter?
The inverter comes with an option for a port (the green plug) for a generator start up, if the battery voltage drops to low, making this unit a true UPS.
From everything i have read so far this unit has to be manually switched between battery or shore power priority (not sure if automatic switching is possible?)
I'v only seen one seller mention a User-defined battery charging voltage option, (which i will ask the seller to confirm) but the Gel-USA setting of 14v fast charge (Bulk) and 13.7v float or the setting for AGM1 14.1v Bulk and 13.4v float, both fall into useable charging parameters for Lifpo4 prismatic cells.

I can tell you im sick of looking at bright yellow inverters.
All the parts for these generic LF inverter are coming out of the same factory and being put inside slightly different metal boxes with slight different specs.
Most retailer dont have any more information than they have already put online.
Honestly for the price I have not found a better/cheaper LF inverter charger.
So when i finally get my hands on one i will report back with anything else i find out. (user functions, Pro and Cons)
I already know I will have to replace the noisy fan for a quieter one.
Only time will tell if they are a reliable inverter?
