Are you reading that on the panel feed OR out of the controller? Is this in bright sun or not? Get back to me with this information and the size of your panel and brand of controller and I can offer more here. All follow ups are included in our fee. And please include the watts rating and voltage of your panel.
Just checking back in to see if you still need some additional input from me on this issue?
That will be kind of slow for battery charging and you might want to add another. Most of these are "plug and play" and adding one is easy and your controller is plenty large enough. That would handle up t 450 watts of output which is 6 -75 watt panels. Thanks for getting back to me and a positive rating on my assistance would be appreciated!
