I agree completely. If you decide later adding some extras, you may need it.
Congratulations, your installation looks very well done. A professional job.
Quote:Quick question since I know little to nothing about solar. Right now my panel is completely shaded from the sun by the trees on the edge of my property, but it still has a view of the clear sky. Is this voltage normal for a shaded panel? I can guess that it depends, but just trying to gauge how well the panel and controller are working.
A battery voltage of 13.75V is absolutely normal when it is being charged.
