The OP has mentioned they want to go fulltime and mostly away from hookups. Obviously they are very new to understanding battery power with different draws from items in the trailer, then add solar into the mix and it might be a little more confusing to them during this time of the year with caviar power wants.
Having 1,280w of solar might be considered moderate amount by some. Unless you don't mind dragging out the generator and listening to it for long periods of time then there shouldn't be no issues at all.
I personally don't like listening to them even mine and it's only eu2200i so it gets run only when necessary and try to use it for the least amount of time. Over the past 40 days boondocking traveling out of CO, UT, NV and AZ now. Shorter daylight hours, overcast and rainy days and one location was no option than pointing the trailer west which is just horrible for my solar production potential. Batteries living in the PSOC (bouncing between 25%-95%) using whatever is needed at anytime during this period of time with the daily use of 200-250ah. Decided yesterday to do a full charge using the generator, it was another overcast/ drizzle day and at 1:45pm (47% SOC) with solar production of only 50ah total for the entire day. The batteries needed 265ah (53%) taking 2 3/4 hours to fill the batteries completely charging to 14.1v at 100a.
If the OP can afford them LiFePO4 batteries can have alot of benefits over dead lead. Weight is major factor when living fulltime and traveling. My entire system solar panels, inverter/ charger, solar controller, batteries and misc wiring was 500# total. Just food for thought.
