In this episode we build a 5 kWh mobile portable rolling solar generator in 15 minutes or less for less than $2000. This portable power station is the Delta pro in Delta ultra killer because of its massive storage capacity and it's massive solar input. This e.g. for hybrid all in one inverter can take 5000 W of solar input and put out 3000 W continuous with up to 6000 W of surge capacity. With enough solar panels you should be able to run this all day. You could run it in your trailer set up for whatever you need it to and you would be good with mounting solar panels on the roof of your trailer. This is a great set up which is portable because it's on wheels and you can wheel it to where ever it needs to go and can easily be recharged by mains power or solar.

EG4 3kW OffGrid Inverter | 3000EHV48 | 3000W Output | 5000W PV Input | 500 VOC Input [$675]
3000EHV48's Design Improvements:
Larger Battery Terminal Connections(Supports up to 2 AWG)
Minor Improvements to the exterior design
Fully compatible with V1 units(may require a simple firmware update, can be found on www.eg4electronics.com)
The EG4 3000EHV48 is a 3000W allinone, multifunction inverter/charger; it combines the capabilities of an inverter, MPPT solar charger, and battery charger to offer uninterrupted power support in a single, portablesized package. Its comprehensive LCD display offers userconfigurable and easyaccessible button operation including battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications.
