Re using the load terminals on the controller, I have found this article which describes the idea that the terminals are powered by the panels as "a common misunderstanding".
Have you ever stared at your solar charge controller, wondering if you should connect your devices to that mysterious "load" terminal? You're not alone.

The
Victron controllers may be different, in view of Wildebus's post, but with my controller and it seems many others the power in fact comes from the
battery. I suppose if the panels are replenishing the
battery at the same rate it makes no difference.
I found it convenient to use the output to power the computer fans I fitted on the fridge vent. As the power comes from the leisure
battery they don't shut down at night!
