360Ah of deep-cycle batteries would require a 40A, 3-stage mains battery charger to properly get them up to a fully charged state. Most people have trouble because they buy too much capacity, but don't have a serious enough charger. Your 75W solar panel & 100W wind genny will be pretty much useless on a battery bank of this size, unless first taken to 98% capacity by a hefty mains charger or alternator with smart regulator. If you've let them drop below 30% charge they will be useless by now i'm afraid!
