I have experience with solar systems and am willing to help you out.
I have some questions.
1 - Are you charging through a solar charge controller?
2 - Is your system properly protected with fuses or DC Breakers?
2 - Do you have a way of measuring voltage and amperage?
3 - Is the wiring clean and corrosion free?

Also if you wish to learn about this (and a ton of other maintence things) There is a good book out there by Nigel Calder - Boatowner's Mechanical and Electrical Manual. (McGraw Hill)
I will send you a PM with my e-mail adress if you want to get back to me quicker.
