Hi all We're making good use of cargo trailer for now, (until our next toy ) I found tiny fridge and wanted to run lights ect, I have two brand new 6 volt batteries, also 90 watt solar panel. What s...

Maybe small tv fridge is 88 watts
That is the "run" wattage, startup surge wattage will be pretty close to 700W-800W.
Some folks have had success with 800W inverters but in reality 1,000W-1,200W (2,000W-2,400W SURGE rating)inverter will ensure a successful fridge startup.
To handle the large startup surge current you will also need to use rather heavy ga of wire, something like 2ga or better and keep the 12V side from the inverter to battery as short as possible. The typical 10 ga wires they give with cheap inverters simply will not do when dealing with high surge currents. Minimizing the voltage drop from battery to the inverter is key to keeping the inverter from shutting down under the surge.
I used 1/0 and have no more than 6ft total wire (three feet for positive and three feet for the negative).
Make darn sure you add in a FUSE for the wire FEEDING the inverter, place it close to the battery as possible. Size the fuse to the wire size..
