Best fixed solar panel size for eb 55-to get most wattage

please give you 2ctz

Here’s a test I did with my EB55 a while back comparing a 200 watt Renogy fixed with a Bluetti 200 watt portable. Bluetti SP200 portable panel vs Renogy 200 watt fixed panel

The Renogy panel has an open circuit voltage of 27.5 which is pretty close to the 28v max of the the EB55.
