Hello Larryboy,

My post to Greg may attempt to answer your question. I'm told by people who are supposed to know, that you need approximately 50% more wattage on the panel than the load you are trying to pull with solar. This is near the capacity of your panel, if this is true. The only way around this would be a timer to reduce the run time to 3-4 hours instead of all night. Hope this helps.

Bob
