Seems like a simple question but.... we're entirely off-grid, powered by a single large pole-mounted solar array and 18.5 Kwh Fortress Power Lithium battery. 2 or 3 days without sunlight and the generator often goes on. On multiple sunny days, the Lithium battery will be at 100%, by early afternoon. At the same time, on partially sunny days an additional array would charge the single battery faster. To diminish any use of the generator, ideally we might add an array and a battery, BUT..... finances for now dictate either doing nothing or choosing between adding a second array or a second battery.
Any suggestions on how to tease this out, are there significant pros (or cons) to one choice over another. Do you need additional data to help us decide?
Many thanks for any help.
