Solar power pack

Hi all, Sorry if this has been asked in different formats etc but can anyone help me with this: I am setting up a solar power unit for a storage container, looking at 2000w inverter to run from 24v battery. My question is, what is the power usage on the stick up external camera please? Need to work out Load analysis for the inverter and panel requirement. Hope this makes sense, basically i want to put a camera connected to a Mifi network inside a 40foot shipping container and plug it in to an inverter instead of powering by battery.
