 Only you will know that, because only you will know what kinds of electrical [[electrical:12v:loads|loads]] you need (or want) to run.  Unlike a wall socket in a house where you can run pretty much anything you want, **using power you make off-grid is a series of choices and compromises**.   Some things are easy to run off-grid;  some things are harder and require more infrastructure, planning, and money. Some things are impractical in campervans.  Car-dwelling presents [[rv:car#power|additional power challenges]] due to limited space and charging methods. Only you will know that, because only you will know what kinds of electrical [[electrical:12v:loads|loads]] you need (or want) to run.  Unlike a wall socket in a house where you can run pretty much anything you want, **using power you make off-grid is a series of choices and compromises**.   Some things are easy to run off-grid;  some things are harder and require more infrastructure, planning, and money.
